当前，随着摄像技术的发展，摄像设备的应用场景也随之丰富，比如将摄像设备应用于视频监控等，而在摄像设备的应用过程中，有时为了拍摄到清晰的图像，需要对摄像设备进行变焦拍摄，这样可以保证拍摄得到的图像放大后依然清晰，然而，在此过程中，容易出现拍摄图像间的位置关系发生变化的情况，使得拍摄图像与被拍摄物的真实情况不相符。而本申请提供的图像处理方法可以解决因变焦出现的拍摄图像间的位置关系发生变化的问题，提高摄像设备在变焦过程中的拍摄准确性。At present, with the development of camera technology, the application scenarios of camera equipment are also enriched, such as the application of camera equipment to video surveillance. Zoom shooting can ensure that the captured image is still clear after zooming in. However, in the process, the positional relationship between the captured images is prone to change, making the captured image inconsistent with the real situation of the subject. However, the image processing method provided by the present application can solve the problem that the positional relationship between captured images changes due to zooming, and improve the shooting accuracy of the camera device during the zooming process.
请参阅图1，图1为本申请实施例提供的一种图像处理方法的第一流程图。Please refer to FIG. 1 . FIG. 1 is a first flowchart of an image processing method provided by an embodiment of the present application.
本申请实施例提供的一种图像处理方法，可以包括以下步骤：An image processing method provided in an embodiment of the present application may include the following steps:
步骤S11：确定摄像设备在变焦过程中出现的光心偏差信息。Step S11: Determine the optical center deviation information that occurs during the zooming process of the imaging device.
实际应用中，可以先确定摄像设备在变焦过程中出现的光心偏差信息。也即本申请发现摄像设备在变焦过程中，会出现光心偏移现象，光心也即光学中心，光心偏移现象指的是变焦前后，光心的位置发生偏差，此种现象产生的原因可能为摄像设备的生产误差，也可能为摄像设备因碰撞等因素造成的光心移动等，光心偏差后，成像图像与光心间的位置关系便会发生变化，由此使得成像图像中物体间的相对位置关系也会发生变化，也即变焦会使得拍摄图像中物体间的相对位置关系发生变化，由此使得图像出现偏差，本申请正是发现了变焦过程中的这一现象，并提出了本申请根据光心偏差信息来对图像进行偏差消除的技术方案。In practical applications, the optical center deviation information that occurs during the zooming process of the imaging device may be determined first. That is to say, the present application finds that during the zooming process of the imaging device, there will be an optical center shift phenomenon. The optical center is also the optical center. The optical center shift phenomenon refers to the deviation of the position of the optical center before and after zooming. The reason may be the production error of the camera equipment, or the optical center movement of the camera equipment due to factors such as collision, etc. After the optical center deviates, the positional relationship between the imaging image and the optical center will change, thus making the object in the imaging image The relative positional relationship between objects will also change, that is, zooming will cause the relative positional relationship between objects in the captured image to change, thereby causing image deviations. This application discovered this phenomenon during the zooming process, and proposed The present application provides a technical solution for eliminating the deviation of the image according to the deviation information of the optical center.
应当指出，本申请中的光心指的是一切方向的光线通过透镜时，都会产生偏折，使光线传播方向发生变化，但透镜上有一点，任意方向的光线通过该点时，光线的传播方向不变，即出射方向和入射方向相互平行，这一点叫透镜的光学中心。It should be pointed out that the optical center in this application refers to the deflection of light rays in all directions passing through the lens, which changes the direction of light propagation. However, there is a point on the lens. When light rays in any direction pass through this point, the propagation of light The direction remains unchanged, that is, the outgoing direction and the incident direction are parallel to each other, which is called the optical center of the lens.
步骤S12：基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到目标图像。Step S12: Based on the optical center deviation information, perform deviation elimination on the image captured by the imaging device to obtain the target image.
实际应用中，在确定出光心偏差信息之后，便可以对摄像设备拍摄的图像进行偏差消除，得到目标图像。In practical applications, after the optical center deviation information is determined, the deviation can be eliminated on the image captured by the camera device to obtain the target image.
本申请提供的一种图像处理方法，能够确定摄像设备在变焦过程中出现的光心偏差信息；基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到目标图像。本申请中，由于确定出了变焦过程中出现的光心偏差信息，而光心偏差信息会导致变焦前后拍摄图像中物体的位置相对关系发生变化，所以之后会基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到位置相对关系不会随变焦变动的目标图像，拍摄准确性高。An image processing method provided by the present application can determine the optical center deviation information that occurs during the zooming process of the imaging device; based on the optical center deviation information, the deviation is eliminated on the image captured by the imaging device to obtain a target image. In this application, since the optical center deviation information that occurs during the zooming process is determined, and the optical center deviation information will cause changes in the relative positions of objects in the captured images before and after zooming, the imaging equipment will be analyzed based on the optical center deviation information. The deviation of the captured image is eliminated to obtain a target image whose position relative relationship does not change with zooming, and the shooting accuracy is high.
本申请实施例提供的一种图像处理方法中，可以通过对摄像设备进行测试来确定摄像设备的光心偏差信息，在此过程中，为了降低测试难度，可以预先选定测试场景，借助摄像设备对测试场景的变焦拍摄图像来确定光心偏差信息，此外，在拍摄图像中，图像的几何中心也即摄像设备的光学中心，所以可以借助几何中心来确定摄像设备的光心偏差信息，也即步骤S11确定出摄像设备在变焦过程中出现的光心偏差信息的步骤，可以具体为：获取摄像设备在不同焦距下对测试场景拍摄得到的测试图像；基于位于测试图像几何中心的对象间的位置信息，确定光心偏差信息。In an image processing method provided by an embodiment of the present application, the optical center deviation information of the camera device can be determined by testing the camera device. In this process, in order to reduce the difficulty of testing, the test scene can be pre-selected, and The optical center deviation information is determined by zooming and shooting images of the test scene. In addition, in the captured images, the geometric center of the image is also the optical center of the camera device, so the geometric center can be used to determine the optical center deviation information of the camera device, that is Step S11 determines the step of determining the optical center deviation information of the imaging device during the zooming process, which can be specifically: obtaining the test images obtained by the imaging device shooting the test scene at different focal lengths; information to determine the optical center deviation information.
实际应用中，为了降低测试复杂度，可以在测试场景中指定目标对象，根据目标对象在变焦过程中的位置变化信息来确定光心偏差信息，比如获取摄像设备在不同焦距下对测试场景拍摄得到的测试图像，基于位于测试图像几何中心的对象间的位置信息，确定光心偏差信息的步骤，可以具体为：在测试场景中确定出目标对象，将摄像设备的焦距调至最大，将摄像设备的屏幕几何中心对准目标对象，保持摄像设备与测试场景间的位置不变，将摄像设备的焦距调至最小，拍摄得到测试图像，由于摄像设备的光心不随变焦偏移的话，目标对象理论上应该位于测试图像的几何中心，所以可以根据测试图像中目标对象的位置及测试图像的几何中心间的位置信息，确定光心偏差信息。In practical applications, in order to reduce the complexity of the test, the target object can be specified in the test scene, and the optical center deviation information can be determined according to the position change information of the target object during the zooming process. The test image, based on the position information between the objects located in the geometric center of the test image, the step of determining the optical center deviation information can be specifically: determine the target object in the test scene, adjust the focal length of the camera device to the maximum, and set the camera device Align the geometric center of the screen with the target object, keep the position between the camera device and the test scene unchanged, adjust the focal length of the camera device to the minimum, and shoot the test image. Since the optical center of the camera device does not shift with the zoom, the target object theory should be located at the geometric center of the test image, so the optical center deviation information can be determined according to the position of the target object in the test image and the position information between the geometric center of the test image.
请参阅图2，图2为本申请实施例提供的一种图像处理方法的第二流程图。Please refer to FIG. 2 . FIG. 2 is a second flowchart of an image processing method provided by an embodiment of the present application.
本申请实施例提供的一种图像处理方法，可以包括以下步骤：An image processing method provided in an embodiment of the present application may include the following steps:
步骤S21：获取第一焦距下，摄像设备对测试场景进行拍摄得到的第一测试图像。Step S21: Acquiring a first test image obtained by shooting a test scene by an imaging device at a first focal length.
步骤S22：获取第二焦距下，摄像设备对测试场景进行拍摄得到的第二测试图像。Step S22: Obtain a second test image obtained by shooting a test scene by the imaging device at the second focal length.
实际应用中，因为摄像设备的光心偏差信息不会随着变焦倍数的变化而变化，所以可以通过两个焦距下的测试图像来确定光心偏差信息，也即获取摄像设备在不同焦距下对测试场景拍摄得到的测试图像的步骤，可以具体为：获取第一焦距下，摄像设备对测试场景进行拍摄得到的第一测试图像；获取第二焦距下，摄像设备对测试场景进行拍摄得到的第二测试图像。In practical applications, because the optical center deviation information of the imaging device does not change with the change of the zoom factor, the optical center deviation information can be determined through the test images at two focal lengths, that is, the optical center deviation information of the imaging device at different focal lengths can be obtained. The steps of the test image obtained by shooting the test scene can be specifically: obtaining the first test image obtained by shooting the test scene by the camera device at the first focal length; obtaining the first test image obtained by shooting the test scene by the camera device at the second focal length; Two test images.
实际应用中，第一焦距和第二焦距的倍数可以根据实际需要确定，比如第一焦距可以为最大焦距，第二焦距可以为原始焦距等。In practical applications, the multiples of the first focal length and the second focal length can be determined according to actual needs, for example, the first focal length can be the maximum focal length, and the second focal length can be the original focal length.
步骤S23：在摄像设备对测试场景的一幅拍摄图像中，将位于第一测试图像与第二测试图像几何中心的对象间的相对位置关系，作为光心偏差信息。Step S23: In one captured image of the test scene by the imaging device, the relative positional relationship between the objects located at the geometric center of the first test image and the second test image is used as the optical center deviation information.
实际应用中，在获取第一测试图像和第二测试图像之后，可以在摄像设备对测试场景的一幅拍摄图像中，将位于第一测试图像与第二测试图像几何中心的对象间的相对位置关系，作为光心偏差信息，具体的，可以直接在第一测试图像或第二测试图像中，将位于第一测试图像与第二测试图像几何中心的对象间的相对位置关系，作为光心偏差信息等；比如，可以在第一测试图像中，确定出位于几何中心的目标对象，在第二测试图像中，将目标对象与第二测试图像的几何中心间的相对位置关系，确定为光心偏差信息。In practical applications, after the first test image and the second test image are acquired, the relative position between the object located in the geometric center of the first test image and the second test image can be calculated in a captured image of the test scene by the camera device relationship, as the optical center deviation information, specifically, the relative positional relationship between the objects located at the geometric center of the first test image and the second test image can be directly in the first test image or the second test image, as the optical center deviation information, etc.; for example, in the first test image, the target object at the geometric center can be determined, and in the second test image, the relative positional relationship between the target object and the geometric center of the second test image can be determined as the optical center Deviation information.
应当指出，由于同一物体在不同焦距下的成像范围不同，所以位于第一测试图像中的目标对象在第二测试图像中的范围会发生变化，为了确定目标对象的位置，可以根据拍摄焦距灵活选择目标对象的范围；并且，在此过程中，可以灵活选择目标对象的范围形状，比如矩形、三角形等，且可以将目标对象的几何中心作为目标对象的位置等。It should be pointed out that since the same object has different imaging ranges at different focal lengths, the range of the target object in the first test image will change in the second test image. In order to determine the position of the target object, it can be flexibly selected according to the shooting focal length The range of the target object; and, in this process, the range shape of the target object can be flexibly selected, such as rectangle, triangle, etc., and the geometric center of the target object can be used as the position of the target object.
步骤S24：基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到目标图像。Step S24: Based on the optical center deviation information, perform deviation elimination on the image captured by the imaging device to obtain the target image.
请参阅图3，图3为本申请实施例提供的一种图像处理方法的第三流程图。Please refer to FIG. 3 . FIG. 3 is a third flowchart of an image processing method provided by an embodiment of the present application.
本申请实施例提供的一种图像处理方法，可以包括以下步骤：An image processing method provided in an embodiment of the present application may include the following steps:
步骤S31：获取第一焦距下，摄像设备对测试场景进行拍摄得到的第一测试图像。Step S31: Obtain a first test image obtained by photographing a test scene by an imaging device at a first focal length.
步骤S32获取第二焦距下，摄像设备对测试场景进行拍摄得到的第二测试图像。Step S32 acquires a second test image obtained by shooting a test scene by the imaging device at the second focal length.
步骤S33：在第一测试图像中，确定位于几何中心的目标对象。Step S33: In the first test image, determine the target object located at the geometric center.
步骤S34：确定目标对象在第二测试图像中的第一位置；确定第二测试图像的几何中心的第二位置；Step S34: determining the first position of the target object in the second test image; determining the second position of the geometric center of the second test image;
步骤S35：将第一位置与第二位置间的比值，作为光心偏差信息。Step S35: Using the ratio between the first position and the second position as the optical center deviation information.
步骤S36：基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到目标图像。Step S36: Based on the optical center deviation information, perform deviation elimination on the image captured by the imaging device to obtain the target image.
实际应用中，可以先确定目标对象在第二测试图像中的第一位置，确定第二测试图像的几何中心的第二位置，将第一位置与第二位置间的比值，作为光心偏差信息；也即可以将位于两幅测试图像几何中心的物体间的坐标比值作为光心偏差信息，这样，在基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到目标图像时，可以直接将图像坐标与光心偏差信息进行相乘或相除，即可进行偏差消除。In practical applications, the first position of the target object in the second test image can be determined first, the second position of the geometric center of the second test image can be determined, and the ratio between the first position and the second position can be used as the optical center deviation information ; That is to say, the coordinate ratio between the objects located at the geometric centers of the two test images can be used as the optical center deviation information, so that, based on the optical center deviation information, the image taken by the camera device is eliminated to obtain the target image. The deviation can be eliminated by multiplying or dividing the image coordinates and the deviation information of the optical center.
实际应用中，为了降低光心偏差信息的复杂度，可以将光心偏差信息分为横坐标偏差信息和纵坐标偏差信息，也即第一位置包括第一横坐标、第一纵坐标；第二位置包括第二横坐标、第二纵坐标；相应的，将第一位置与第二位置间的比值，作为光心偏差信息的步骤，可以具体为：确定第一横坐标与第二横坐标间的横坐标比例；确定第一纵坐标与第二纵坐标间的纵坐标比例；将横坐标比例和纵坐标比例作为光心偏差信息。应当指出，横坐标比例也即横坐标偏差信息，纵坐标比例也即纵坐标偏差信息。In practical applications, in order to reduce the complexity of the optical center deviation information, the optical center deviation information can be divided into abscissa deviation information and ordinate deviation information, that is, the first position includes the first abscissa and the first ordinate; the second The position includes a second abscissa and a second ordinate; correspondingly, the step of using the ratio between the first position and the second position as the optical center deviation information may specifically be: determine the distance between the first abscissa and the second abscissa The abscissa ratio; determine the ordinate ratio between the first ordinate and the second ordinate; use the abscissa ratio and the ordinate ratio as the optical center deviation information. It should be noted that the ratio of the abscissa is also the deviation information of the abscissa, and the ratio of the ordinate is also the deviation information of the ordinate.
具体应用场景中，基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到目标图像的过程中，若摄像设备拍摄图像时焦距变大，也即当前拍摄得到的图像是经过调大焦距操作得到的图像，则需要将图像中待调整对象的坐标与光心偏差信息的乘积，作为目标图像中待调整对象的新坐标。In a specific application scenario, based on the optical center deviation information, the deviation of the image captured by the camera device is eliminated. In the process of obtaining the target image, if the focal length of the image captured by the camera device becomes larger, that is, the currently captured image is obtained after the focal length is increased. To operate the obtained image, the product of the coordinates of the object to be adjusted in the image and the optical center deviation information needs to be used as the new coordinates of the object to be adjusted in the target image.
具体应用场景中，基于光心偏差信息，对摄像设备拍摄的图像进行偏差消除，得到目标图像的过程中，若摄像设备拍摄图像时焦距变小，也即当前拍摄得到的图像是经过调小焦距操作得到的图像，则需要将图像中待调整对象的坐标与光心偏差信息的比值，作为目标图像中待调整对象的新坐标。In a specific application scenario, based on the optical center deviation information, the deviation of the image captured by the camera device is eliminated. In the process of obtaining the target image, if the focal length becomes smaller when the camera device captures the image, that is, the currently captured image is obtained after reducing the focal length. To operate the obtained image, it is necessary to use the ratio of the coordinates of the object to be adjusted in the image to the optical center deviation information as the new coordinates of the object to be adjusted in the target image.
实际应用中，本申请中的横坐标与纵坐标可以为摄像设备的屏幕坐标系下的坐标值。也即可以根据屏幕坐标系来确定光心偏差信息，由于屏幕坐标系与摄像设备的屏幕分辨率相关，所以可以基于摄像设备的屏幕分辨率来确定光心偏差信息，比如摄像设备的分辨率为(width，height)，原先位于第一测试图像几何中心处的物体A，在第二测试图像中的坐标为(x，y)，则可以将(2x/width)作为横坐标比例，将(2y/height)作为纵坐标比例等。In practical applications, the abscissa and ordinate in this application may be coordinate values in the screen coordinate system of the imaging device. That is, the optical center deviation information can be determined according to the screen coordinate system. Since the screen coordinate system is related to the screen resolution of the camera device, the optical center deviation information can be determined based on the screen resolution of the camera device. For example, the resolution of the camera device is (width, height), the object A originally located at the geometric center of the first test image, the coordinates in the second test image are (x, y), then (2x/width) can be used as the abscissa ratio, and (2y /height) as the ordinate scale, etc.
