基于上文步骤11至步骤12的相关内容可知，在一些应用场景下，当地图处于展示状态时，如果想要针对目标建筑群进行位置确定处理，则可以先利用该目标建筑群对应的地图展示配置参数调整地图的展示状态，得到调整后的地图，以使该调整后的地图能够在确保该目标建筑群完整的前提下更清晰地描述出该目标建筑群；再针对该调整后的地图进行截图处理，以得到该目标建筑群对应的图像数据，以使该图像数据能够清晰完整地展示目标建筑群，以便后续能够借助针对该图像数据的处理过程(比如，下文S2-S3所示的处理过程)，确定出该目标建筑群中各个建筑物所处位置。Based on the relevant content of steps 11 to 12 above, in some application scenarios, when the map is in the display state, if you want to determine the location of the target building group, you can first use the map display corresponding to the target building group. Configure parameters to adjust the display status of the map to obtain an adjusted map so that the adjusted map can describe the target building group more clearly while ensuring the completeness of the target building group; and then proceed with the adjusted map Screenshot processing to obtain the image data corresponding to the target building group, so that the image data can clearly and completely display the target building group, so that subsequent processing of the image data can be used (for example, the processing shown in S2-S3 below) process) to determine the location of each building in the target building complex.
基于上文S1的相关内容可知，如果想要针对目标建筑群进行位置确定处理，则获取该目标建筑群对应的图像数据，以使该图像数据携带有该目标建筑群中各个建筑物对应的像素点，从而使得该图像数据能够表示出该目标建筑群中各个建筑物所处位置。Based on the relevant content of S1 above, it can be known that if you want to perform position determination processing on the target building group, then obtain the image data corresponding to the target building group, so that the image data carries the pixels corresponding to each building in the target building group. points, so that the image data can represent the location of each building in the target building group.
S2：从图像数据中确定各建筑物对应的边缘点集合。S2: Determine the edge point set corresponding to each building from the image data.
其中，对于任一建筑物来说，该建筑物对应的边缘点集合用于记录该建筑物在上文图像数据上所占用的所有像素点中位于边缘位置的像素点，以使该建筑物对应的边缘点集合能够描述出该建筑物在该图像数据中所呈现的轮廓。Among them, for any building, the edge point set corresponding to the building is used to record the pixel points located at the edge among all the pixel points occupied by the building on the above image data, so that the building corresponds to The set of edge points can describe the outline of the building in the image data.
另外，本申请不限定上文S2的实施方式，比如，该S2可以采用现有的或者未来出现的任意一种能够从图像数据中提取出一些对象的边缘信息的方法(比如，任意一种边缘提取方法)进行实施。In addition, this application does not limit the implementation of S2 above. For example, S2 can use any existing or future method that can extract edge information of some objects from image data (such as any edge information). Extraction method) is implemented.
实际上，为了更好地提高边缘点集合的确定效果，本申请还提供了上文S2的一种可能的实施方式，在该实施方式中，当上文图像数据至少包括至少一个建筑物对应的像素点时，该S2具体可以包括下文步骤21-步骤23。In fact, in order to better improve the determination effect of the edge point set, this application also provides a possible implementation of the above S2. In this implementation, when the above image data at least includes at least one building corresponding When selecting pixel points, S2 may specifically include steps 21 to 23 below.
步骤21：对上文图像数据中除了至少一个建筑物对应的像素点以外的其他像素点进行挖空处理，得到建筑物描述图像，该建筑物描述图像包括上文至少一个建筑物对应的像素点。Step 21: Hole out pixels other than the pixels corresponding to at least one building in the above image data to obtain a building description image. The building description image includes the pixels corresponding to at least one building above. .
其中，建筑物描述图像用于只记录上文图像数据所描述的各个建筑物在该图像数据上所占用的像素点，以使该建筑物描述图像能够表示出上文图像数据所描述的所有建筑物。可见，该建筑物描述图像只包括上文至少一个建筑物对应的像素点。Among them, the building description image is used to record only the pixel points occupied by each building described in the above image data on the image data, so that the building description image can represent all the buildings described in the above image data. things. It can be seen that the building description image only includes pixels corresponding to at least one building above.
另外，本申请不限定挖空处理的实施方式，比如，其具体可以为：只是单纯地删除了像素点的像素值，并保留了像素点所处位置。作为示例，当上文图像数据采用下文公式(1)所示的F1进行实施时，如果需要针对该F1中第2行第2列像素点进行挖空处理，则可以得到下文公式(2)所示的F2这一图像数据。In addition, this application does not limit the implementation of the hollowing out process. For example, it can be as follows: simply deleting the pixel value of the pixel and retaining the location of the pixel. As an example, when the above image data is implemented using F1 shown in the following formula (1), if it is necessary to hollow out the pixels in the 2nd row and 2nd column of the F1 , the following formula (2) can be obtained ) is the image data of F2 shown.
其中，F1表示挖空处理前的图像数据；F2表示针对该F1中第2行第2列像素点进行挖空处理之后的图像数据。Among them, F1 represents the image data before hollowing out; F2 represents the image data after hollowing out the pixels in row 2 and column 2 of F1 .
基于上文步骤21的相关内容可知，在获取到包括至少一个建筑物对应的像素点的图像数据之后，可以利用该图像数据中所记录的所有建筑物对应的像素点，构建建筑物描述图像，以使该建筑物描述图像只包括这些建筑物对应的像素点，从而使得该建筑物描述图像只用于描述这些建筑物在该图像数据中所呈现的状态，如此能够有效地避免该图像数据中其他像素点(比如，用于两个建筑物之间的空地的像素点)对建筑物位置确定所造成的干扰，从而有利于提高位置确定效果。Based on the relevant content of step 21 above, it can be known that after obtaining the image data including the pixel points corresponding to at least one building, the building description image can be constructed using the pixel points corresponding to all the buildings recorded in the image data. So that the building description image only includes the pixels corresponding to these buildings, so that the building description image is only used to describe the state of these buildings in the image data, which can effectively avoid the image data. The interference caused by other pixels (for example, pixels used for the open space between two buildings) on the determination of the location of the building is beneficial to improving the location determination effect.
步骤22：若上文建筑物描述图像中存在第六类点以及该第六类点对应的相邻点，而且该第六类点对应的相邻点的个数达到第四阈值，则对该建筑物描述图像中的第六类点进行挖空处理，得到边缘点描述图像，该边缘点描述图像包括所述至少一个建筑物对应的边缘点。Step 22: If there are sixth category points and adjacent points corresponding to the sixth category points in the above building description image, and the number of adjacent points corresponding to the sixth category points reaches the fourth threshold, then The sixth type of points in the building description image are hollowed out to obtain an edge point description image. The edge point description image includes edge points corresponding to the at least one building.
其中，第六类点用于代表上文建筑物描述图像中存在的、位于某个建筑物所占区域内部的像素点，以使该第六类点能够代表内部点(也就是，非边缘点)。其中，该内部点是指该建筑物描述图像中存在的、位于某个建筑物所占区域内部的像素点。可见，在一种可能的实施方式下，该第六类点可以包括所有建筑物对应的内部点。Among them, the sixth type of points is used to represent the pixel points that exist in the above building description image and are located inside the area occupied by a certain building, so that the sixth type of points can represent internal points (that is, non-edge points ). Among them, the internal points refer to pixel points that exist in the building description image and are located inside the area occupied by a certain building. It can be seen that, in a possible implementation, the sixth type of points may include internal points corresponding to all buildings.
另外，对于上文第六类点来说，因该第六类点属于内部点，以使该第六类点在上文建筑物描述图像中存在很多相邻点(比如，在前、后、左、右、以及四个斜角方向上出现的相邻点)，从而使得该第六类点具有以下特点：该建筑物描述图像中存在该第六类点以及该第六类点对应的相邻点，而且该第六类点对应的相邻点的个数达到第四阈值。其中，该第四阈值可以预先设定，比如，其可以为8。该第六类点对应的相邻点是指在该建筑物描述图像中存在的与该第六类点位置相邻(比如，在前、后、左、右、以及四个斜角方向上相邻)的有效像素点。该有效像素点是指该建筑物描述图像中存在的、具有像素值的像素点(也就是，用于描述某个建筑物的像素点)。In addition, for the sixth type of point above, because the sixth type point belongs to the internal point, there are many adjacent points (for example, in the front, back, front, back, etc.) in the above building description image. adjacent points appearing in the left, right, and four oblique directions), so that the sixth type point has the following characteristics: the sixth type point and the corresponding phase of the sixth type point exist in the building description image adjacent points, and the number of adjacent points corresponding to the sixth type point reaches the fourth threshold. The fourth threshold can be preset, for example, it can be 8. The adjacent points corresponding to the sixth type point refer to the positions adjacent to the sixth type point in the building description image (for example, in the front, back, left, right, and four oblique directions). neighboring) effective pixels. The effective pixel points refer to pixel points with pixel values that exist in the building description image (that is, pixel points used to describe a certain building).
边缘点描述图像用于描述在上文图像数据中所呈现的各个建筑物的轮廓；而且该边缘点描述图像只包括上文至少一个建筑物对应的边缘点。其中，对于任一建筑物，该建筑物对应的边缘点用于描述该建筑物在该图像数据中所呈现的轮廓。The edge point description image is used to describe the outline of each building presented in the above image data; and the edge point description image only includes edge points corresponding to at least one of the above buildings. Wherein, for any building, the edge points corresponding to the building are used to describe the outline of the building presented in the image data.
基于上文步骤22的相关内容可知，在获取到用于描述上文至少有一个建筑物所处状态的建筑物描述图像之后，可以从该建筑物描述图像中挖空每个建筑物对应的内部点，以使挖空处理后的图像数据中只保留了每个建筑物对应的边缘点，以使该挖空处理后的建筑物描述图像能够以较少像素点表示出每个建筑物所处位置。Based on the relevant content of step 22 above, it can be known that after obtaining the building description image used to describe the state of at least one of the above buildings, the interior corresponding to each building can be hollowed out from the building description image. points, so that only the edge points corresponding to each building are retained in the image data after hollowing out, so that the building description image after hollowing out can express the location of each building with fewer pixels. Location.
步骤23：对上文边缘点描述图像中的像素点进行分组处理，得到各建筑物对应的边缘点集合。Step 23: Group the pixels in the edge point description image above to obtain a set of edge points corresponding to each building.
需要说明的是，本申请不限定步骤23的实施方式，例如，其可以采用现有的或者未来出现的任意一种能够将上文边缘点描述图像中像素点进行分组处理的方案进行实施。It should be noted that this application does not limit the implementation of step 23. For example, it can be implemented using any existing or future solution that can group the pixels in the image described by the above edge points.
又如，上文步骤23可以借助近邻传播方式进行实现，其具体为：首先，从该边缘点描述图像中随机选择一个像素点，并利用该像素点初始化一个建筑物对应的边缘点集合，以使该边缘点集合包括该像素点；其次，查找距离该像素点最近的像素点，并将该“距离该像素点最近的像素点”添加至该边缘点集合；然后，查找距离该“距离该像素点最近的像素点”最近的像素点，并将该查找到的像素点添加至该边缘点集合；如此迭代多次即可构成该建筑物对应的边缘点集合；而且每个建筑物对应的边缘点集合的确定过程均采用前述过程进行实现即可。需要说明的是，本段所涉及的迭代过程的停止条件为：在查找过程中，查找到的像素点与作为查找关键词的像素点之间的距离大于预设距离阈值，该预设距离阈值可以依据实际的应用场景进行设定。As another example, step 23 above can be implemented using the nearest neighbor propagation method, which is specifically as follows: first, randomly select a pixel point from the edge point description image, and use the pixel point to initialize a set of edge points corresponding to the building, so as to Make the edge point set include the pixel point; secondly, find the pixel point closest to the pixel point, and add the "pixel point closest to the pixel point" to the edge point set; then, find the distance from the "pixel point closest to the pixel point" The nearest pixel of the pixel is the nearest pixel, and the found pixel is added to the edge point set; by iterating many times in this way, the edge point set corresponding to the building can be formed; and the edge point set corresponding to each building is The determination process of the edge point set can be implemented using the aforementioned process. It should be noted that the stopping condition of the iterative process involved in this paragraph is: during the search process, the distance between the found pixel and the pixel used as the search keyword is greater than the preset distance threshold, which is It can be set according to the actual application scenario.
基于上文步骤21至步骤23的相关内容可知，在获取到用于描述至少一个建筑物的图像数据之后，可以先从该图像数据中获取所有建筑物对应的像素点；再挖空每个建筑物对应的内部点；最后，对剩余点进行分组处理，即可得到各个建筑物对应的边缘点集合，以便后续能够基于各个建筑物对应的边缘点集合，分别分析各个建筑物所处位置。Based on the relevant contents of steps 21 to 23 above, it can be known that after obtaining the image data describing at least one building, the pixels corresponding to all buildings can be obtained from the image data; and then each building can be hollowed out internal points corresponding to the object; finally, the remaining points are grouped to obtain the edge point set corresponding to each building, so that the location of each building can be analyzed based on the edge point set corresponding to each building.
基于上文S2的相关内容可知，在获取到用于描述上文至少一个建筑物的图像数据之后，可以从该图像数据中提取出各个建筑物对应的边缘点集合，以使各个建筑物对应的边缘点集合分别能够描述出各个建筑物在该图像数据中所呈现的轮廓，以便后续能够基于各个建筑物对应的边缘点集合，分别分析各个建筑物所处位置。Based on the relevant content of S2 above, it can be known that after obtaining the image data used to describe at least one building above, the edge point set corresponding to each building can be extracted from the image data, so that the edge points corresponding to each building can be The edge point set can describe the outline of each building in the image data, so that the location of each building can be analyzed based on the edge point set corresponding to each building.
S3：对于任一建筑物，利用该建筑物对应的边缘点集合，分析该建筑物的位置信息。S3: For any building, use the edge point set corresponding to the building to analyze the location information of the building.
其中，对于任一建筑物来说，该建筑物的位置信息用于描述该建筑物所处的地理位置；而且本申请不限定该建筑物的位置信息的表示方式，比如，其可以借助任意一种地理位置表示方法(比如，经纬度等表示方法)进行实施。Among them, for any building, the location information of the building is used to describe the geographical location of the building; and this application does not limit the representation method of the location information of the building. For example, it can use any A geographical location representation method (such as longitude and latitude representation methods) is implemented.
另外，本申请不限定上文S3的实施方式，例如，当上文“至少一个建筑物”包括N个建筑物时，该S3具体可以为：先将第n个建筑物对应的边缘点集合中各个像素点的图像坐标转换为地理坐标，得到该边缘点集合中各个像素点对应的地理坐标；再将该边缘点集合中所有像素点对应的地理坐标进行集合，得到该第n个建筑物的位置信息，以使该位置信息包括该边缘点集合中所有像素点对应的地理坐标。其中，该像素点的图像坐标用于描述该像素点在上文图像数据的图像坐标系下所具有的坐标；而且本申请不限定该图像坐标系，比如，该图像坐标系是指将该图像数据的左上角作为原点所建立的坐标系。需要说明的是，本申请不限定坐标转换的实施方式，比如，其可以采用现有的或者未来出现的任意一种能够将地图截图中的图像坐标转换为实际的地理坐标的方法(比如，按照某种预先设定的转换规则进行坐标转换等实施方式)进行实施。其中，n为正整数，n≤N，N为正整数，N表示上文图像数据所描述的建筑物的个数。还需要说明的是，在一些应用场景下，本申请所涉及的坐标转换过程可能需要使用上文图像数据自身所具有的地理坐标信息(比如，该图像数据所描述的建筑群所处区域的地理坐标范围等)。In addition, this application does not limit the implementation of the above S3. For example, when the above "at least one building" includes N buildings, the S3 may specifically be: first, collect the edge points corresponding to the n-th building. The image coordinates of each pixel point are converted into geographical coordinates to obtain the geographical coordinates corresponding to each pixel point in the edge point set; then the geographical coordinates corresponding to all pixel points in the edge point set are collected to obtain the nth building Location information, so that the location information includes the geographical coordinates corresponding to all pixels in the edge point set. Among them, the image coordinates of the pixel point are used to describe the coordinates of the pixel point in the image coordinate system of the above image data; and this application does not limit the image coordinate system. For example, the image coordinate system refers to the image coordinate system. A coordinate system established with the upper left corner of the data as the origin. It should be noted that this application does not limit the implementation of coordinate conversion. For example, it can adopt any existing or future method that can convert the image coordinates in the map screenshot into actual geographical coordinates (for example, according to Some preset conversion rules are used to implement coordinate conversion and other implementations). Among them, n is a positive integer, n≤N, N is a positive integer, and N represents the number of buildings described in the above image data. It should also be noted that in some application scenarios, the coordinate conversion process involved in this application may need to use the geographical coordinate information of the above image data itself (for example, the geographical coordinate information of the area where the building group described by the image data is located). coordinate range, etc.).
实际上，对于上文边缘点集合来说，该边缘点集合中存在的像素点依旧比较多，故为了更好地节省资源(比如，存储资源、计算资源、时间资源等)，本申请还提供了上文S3的一种可能的实施方式，在该实施方式中，当上文“至少一个建筑物”包括N个建筑物时，该S3具体可以包括下文步骤31-步骤32。In fact, for the above edge point set, there are still relatively many pixels in the edge point set. Therefore, in order to better save resources (such as storage resources, computing resources, time resources, etc.), this application also provides A possible implementation of the above S3 is provided. In this implementation, when the above "at least one building" includes N buildings, the S3 may specifically include the following steps 31 to 32.
步骤31：对第n个建筑物对应的边缘点集合进行简化处理，得到该第n个建筑物对应的简化处理后的边缘点集合，以使该第n个建筑物对应的简化处理后的边缘点集合中的像素点个数少于该第n个建筑物对应的边缘点集合的像素点个数。其中，n为正整数，n≤N，N为正整数。Step 31: Simplify the set of edge points corresponding to the nth building to obtain a set of simplified edge points corresponding to the nth building, so that the set of simplified edges corresponding to the nth building is The number of pixels in the point set is less than the number of pixels in the edge point set corresponding to the n-th building. Among them, n is a positive integer, n≤N, and N is a positive integer.
其中，简化处理用于删除一个建筑物对应的边缘点集合中存在的一些使用价值比较小的像素点。Among them, the simplification process is used to delete some pixels with relatively small use value existing in the edge point set corresponding to a building.
另外，本申请不限定简化处理的实施方式，比如，其可以为：按照预先依据应用场景所设定的简化处理规则，对第n个建筑物对应的边缘点集合进行简化处理，得到该第n个建筑物对应的简化处理后的边缘点集合。其中，n为正整数，n≤N，N为正整数。In addition, this application does not limit the implementation of the simplification process. For example, it can be: according to the simplification processing rules set in advance according to the application scenario, the edge point set corresponding to the n-th building is simplified to obtain the n-th building. The simplified set of edge points corresponding to each building. Among them, n is a positive integer, n≤N, and N is a positive integer.
此外，为了更好地理解简化处理，下面结合一些情况进行说明。In addition, in order to better understand the simplified processing, some situations are explained below.
情况1，在一些应用场景下，对于由上文边缘点集合中多个像素点所构成的斜线来说，该斜线可能会因为矢量像素化的原因产生的锯齿情况(比如，由图3或者图4中“处理前的斜线”所示的锯齿情况)，以使该锯齿情况下作为尖齿的像素点所提供的位置信息的使用价值不大。Case 1: In some application scenarios, for a diagonal line composed of multiple pixels in the above edge point set, the diagonal line may be jagged due to vector pixelation (for example, as shown in Figure 3 Or the jaggy situation shown by the "slant line before processing" in Figure 4), so that the position information provided by the pixel points as sharp teeth in this jaggy situation is of little value.
基于上段内容可知，为了更好地提高简化效果，可以针对上文边缘点集合进行锯齿简化处理。基于此可知，在一种可能的实施方式下，上文简化处理可以至少包括下文步骤311。Based on the above paragraph, it can be seen that in order to better improve the simplification effect, sawtooth simplification can be performed on the above edge point set. Based on this, it can be known that, in a possible implementation, the above simplified processing may include at least the following step 311.
步骤310：若第n个建筑物对应的边缘点集合中存在第一类点，则从该第n个建筑物对应的边缘点集合中删除该第一类点；该第n个建筑物对应的边缘点集合包括该第一类点对应的第一邻点和该第一类点对应的第二邻点；该第一邻点与该第二邻点位于同一条直线上，该第一类点不位于该直线上。其中，n为正整数，n≤N，N为正整数。Step 310: If there are first-type points in the edge point set corresponding to the n-th building, delete the first-type point from the edge point set corresponding to the n-th building; The edge point set includes a first neighbor point corresponding to the first type point and a second neighbor point corresponding to the first type point; the first neighbor point and the second neighbor point are located on the same straight line, and the first type point is not on this straight line. Among them, n is a positive integer, n≤N, and N is a positive integer.
其中，第一类点是指满足预设锯齿简化条件的像素点，以使该第一类点能够代表充当尖齿的像素点(比如，图4所示的Pn这一像素点)。The first type of points refers to pixels that meet the preset sawtooth simplification conditions, so that the first type of points can represent pixels that serve as tines (for example, the pixel Pn shown in Figure 4).
预设锯齿简化条件用于筛选锯齿情况下所需删除的像素点(也就是，上文第一类点)；而且本申请不限定该预设锯齿简化条件，比如，当上文第n个建筑物对应的边缘点集合包括该第一类点(比如，图4所示的Pn这一像素点)、该第一类点对应的第一邻点(比如，图4所示的Pn-1这一像素点)、以及该第一类点对应的第二邻点(比如，图4所示的Pn+1这一像素点)时，该预设锯齿简化条件具体可以为：该第一邻点与该第二邻点位于同一条直线上，而且该第一类点不位于该直线上。其中，该第一邻点是指在某个方向(比如，图4所示的斜线方向等)上排列位置比该第一类点所处位置靠前，而且与该第一类点所处位置相邻的像素点。该第二邻点是指在该方向上排列位置比该第一类点所处位置靠后，而且与该第一类点所处位置相邻的像素点。可见，该第一邻点、该第一类点以及该第二邻点是一组位置依次相邻的像素点。The preset sawtooth simplification condition is used to filter the pixels that need to be deleted in the case of sawtooth (that is, the first type of points above); and this application does not limit the preset sawtooth simplification condition, for example, when the nth building above The set of edge points corresponding to the object includes the first type point (for example, the pixel point Pn shown in Figure 4), the first neighbor point corresponding to the first type point (for example, the Pn - shown in Figure 41 ), and the second neighbor point corresponding to the first type point (for example, the pixel point Pn+1 shown in Figure 4), the preset sawtooth simplification condition can be specifically: the third A neighbor point is on the same straight line as the second neighbor point, and the first type point is not on the straight line. Wherein, the first neighbor point means that the arrangement position in a certain direction (for example, the diagonal direction shown in Figure 4, etc.) is earlier than the position of the first type point, and is located in the same direction as the first type point. adjacent pixels. The second neighbor point refers to a pixel point arranged behind the position of the first type point in the direction and adjacent to the position of the first type point. It can be seen that the first neighbor point, the first type point and the second neighbor point are a group of pixel points that are adjacent in sequence.
又如，在一些应用场景下，上文预设锯齿简化条件可以用于筛选锯齿情况下充当尖齿的像素点(比如，图4所示的Pn这一像素点)。基于此可知，在一种可能的实施方式下，当上文第n个建筑物对应的边缘点集合包括该第一类点(比如，图4所示的Pn这一像素点)、该第一类点对应的第一邻点(比如，图4所示的Pn-1这一像素点)、以及该第一类点对应的第二邻点(比如，图4所示的Pn+1这一像素点)时，该预设锯齿简化条件具体可以为：该第一类点位于由该第一类点、该第一邻点以及该第二邻点所构成的锯齿形状(比如，图4中左边虚线框所框定的形状)中的尖齿位置(比如，图4中Pn这一像素点在图4中左边虚线框所框定的形状内所处位置)。可见，该第一类点可以位于其前后相邻点之间的犄角位置，比如，左-中上-右。For another example, in some application scenarios, the preset aliasing simplified conditions above can be used to filter pixels that serve as sharp teeth in the case of aliasing (for example, the pixel Pn shown in Figure 4). Based on this, it can be seen that, in a possible implementation, when the edge point set corresponding to the n-th building above includes the first type of point (for example, the pixel point Pn shown in Figure 4), the The first neighbor point corresponding to a type of point (for example, the pixel point Pn-1 shown in Figure 4), and the second neighbor point corresponding to the first type point (for example, Pn+ shown in Figure 41 this pixel), the preset sawtooth simplification condition can be specifically: the first type point is located in a sawtooth shape composed of the first type point, the first neighbor point and the second neighbor point (for example, The position of the tines in the shape framed by the left dotted box in Figure 4) (for example, the position of the pixel point Pn in Figure 4 within the shape framed by the left dotted box in Figure 4). It can be seen that the first type point can be located at the corner position between its front and rear adjacent points, for example, left-middle-upper-right.
基于上文步骤310的相关内容可知，在一些应用场景中，对于任一建筑物来说，当获取到该建筑物对应的边缘点集合之后，可以检测该边缘点集合中是否存在满足预设锯齿简化条件的第一类点，若存在，则为了更好地提高简化效果，可以直接从该边缘点集合中删除该第一类点，以使删除处理后的边缘点集合中不存在满足预设锯齿简化条件的第一类点，从而使得删除处理后的边缘点集合中不存在因锯齿情况而导致的具有较小使用价值的像素点，进而使得该删除处理后的边缘点集合能够以更少的像素点表示出该建筑物所处位置。Based on the relevant content of step 310 above, it can be known that in some application scenarios, for any building, after obtaining the edge point set corresponding to the building, it can be detected whether there is a preset jaggedness in the edge point set. If the first type point of the simplified condition exists, in order to better improve the simplification effect, the first type point can be directly deleted from the edge point set, so that there is no edge point set after deletion that satisfies the preset The first type of points under the aliasing simplification condition, so that there are no pixels with smaller use value due to aliasing in the deleted edge point set, which in turn enables the deleted edge point set to be processed with fewer The pixels represent the location of the building.
情况2，在一些应用场景下，对于由上文边缘点集合来说，该边缘点集合中多个位置依次相邻的像素点可以形成一条直线，以使该直线内处于中间位置的像素点所提供的位置信息的使用价值不大。Case 2: In some application scenarios, for the above edge point set, multiple adjacent pixels in the edge point set can form a straight line, so that the pixels in the middle position within the straight line are The location information provided is of little use.
基于上段内容可知，为了更好地提高简化效果，可以针对上文边缘点集合进行中心点简化处理。基于此可知，在一种可能的实施方式下，上文简化处理可以至少包括下文步骤311。Based on the above paragraph, it can be seen that in order to better improve the simplification effect, the center point simplification process can be performed on the above edge point set. Based on this, it can be known that, in a possible implementation, the above simplified processing may include at least the following step 311.
