For example, the scanning function of an electronic device.

目前，可通过扫描仪实现对目标对象的扫描，但不便于携带。若通过电子设备的摄像头拍摄目标对象，得到目标对象对应的图像，可以理解实现对目标对象的扫描。由于摄像头的镜头小，且镜头的焦距通常在2.5厘米左右，利用摄像头进行扫描得到的图像容易出现失真，导致得到的图像准确性低。At present, the scanning of the target object can be realized by a scanner, but it is not easy to carry. If the target object is photographed by the camera of the electronic device and an image corresponding to the target object is obtained, it can be understood that the scanning of the target object is realized. Because the lens of the camera is small, and the focal length of the lens is usually about 2.5 cm, the image obtained by scanning with the camera is prone to distortion, resulting in low accuracy of the obtained image.

具体实施方式detailed description

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

本发明还提供一个实施例的扫描方法，应用于电子设备，如图1所示，电子设备包括光学指纹模组101以及OLED(Organic Light-Emitting Diode，有机发光二极管)显示屏103，光学指纹模组101位于OLED显示屏103下方，可以理解，OLED显示屏103下方为电子设备内侧，即光学指纹模组101是置于电子设备内的。The present invention also provides a scanning method of an embodiment, which is applied to an electronic device. As shown in FIG. The group 101 is located below theOLED display 103. It can be understood that the bottom of theOLED display 103 is inside the electronic device, that is, the optical fingerprint module 101 is placed in the electronic device.

如图2所示，本实施例提供的扫描方法包括：As shown in Figure 2, the scanning method provided in this embodiment includes:

步骤201：接收用户的扫描输入。Step 201: Receive a user's scan input.

可将电子设备靠近待扫描对象104，使待扫描对象104可紧贴电子设备的OLED显示屏103远离光学指纹模组101的外侧面。通过用户的扫描输入(例如，对扫描按钮的点击输入等)，开启扫描。The electronic device can be placed close to theobject 104 to be scanned, so that theobject 104 to be scanned can be close to theOLED display screen 103 of the electronic device and away from the outer surface of the optical fingerprint module 101 . Scanning is started by the user's scanning input (for example, a click input on a scanning button, etc.).

步骤202：响应于扫描输入，控制OLED显示屏向外发出第一光线。Step 202: In response to the scan input, control the OLED display to emit a first light.

OLED显示屏103发光后，发出的第一光线可向电子设备外侧传输，上述OLED显示屏向外发出第一光线，可以理解为，OLED显示屏向电子设备外侧发出第一光线，即可传输到电子设备外侧。优选地，可向OLED显示屏103远离光学指纹模组101的一侧(即OLED显示屏103的外侧，在电子设备外侧)发出第一光线。在接收到用户的扫描输入后，响应于该扫描输入，即可控制OLED显示屏103向外发出第一光线。在一个示例中，OLED显示屏103中包括OLED发光二极管102，可控制OLED显示屏103的OLED发光二极管102发出第一光线，即可通过OLED显示屏103中OLED发光二极管102点亮发光，从而实现OLED显示屏103向外发出第一光线。After theOLED display 103 emits light, the emitted first light can be transmitted to the outside of the electronic device. outside of electronic equipment. Preferably, the first light can be emitted to the side of theOLED display 103 away from the optical fingerprint module 101 (ie, the outside of theOLED display 103 , outside the electronic device). After receiving the scanning input from the user, in response to the scanning input, theOLED display screen 103 can be controlled to emit the first light. In one example, theOLED display 103 includes an OLED light-emitting diode 102, and the OLED light-emitting diode 102 of theOLED display 103 can be controlled to emit the first light, that is, the OLED light-emitting diode 102 in theOLED display 103 can be lighted to emit light, thereby realizing TheOLED display screen 103 emits first light outward.

步骤203：基于光学指纹模组对接收的第二光线进行光电转换得到灰度图像。Step 203: Based on the optical fingerprint module, the received second light is photoelectrically converted to obtain a grayscale image.

通过光学指纹模组可接收第二光线，并通过光学指纹模组对其进行光电转换得到灰度图像，从而可获取基于光学指纹模组对接收的第二光线进行光电转换得到的灰度图像。其中，第二光线为第一光线经过待扫描对象后反射至光学指纹模组的反射光线，即OLED显示屏103向外发出第一光线，待扫描对象置于电子设备外侧，第一光线经过待扫描对象后，反射至光学指纹模组，光学指纹模组即可接收反射的第二光线，并对接收的第二光线进行光电转换得到灰度图像。优选地，待扫描对象可置于OLED显示屏远离光学指纹模组101的外侧面，可向OLED显示屏的远离光学指纹模组101的外侧发出第一光线，经过待扫描对象后反射。不同的待扫描对象，其形状或颜色等不尽相同，反射的第二光线的能量则不尽相同，如此，得到的灰度图像不尽相同。The second light can be received by the optical fingerprint module and photoelectrically converted by the optical fingerprint module to obtain a grayscale image, so that the grayscale image obtained by photoelectrically converting the received second light by the optical fingerprint module can be obtained. Wherein, the second light is the reflected light of the first light passing through the object to be scanned and reflected to the optical fingerprint module, that is, theOLED display screen 103 emits the first light outward, the object to be scanned is placed outside the electronic device, and the first light passes through the object to be scanned. After the object is scanned, it is reflected to the optical fingerprint module, and the optical fingerprint module can receive the reflected second light, and perform photoelectric conversion on the received second light to obtain a grayscale image. Preferably, the object to be scanned can be placed on the outer side of the OLED display away from the optical fingerprint module 101, and the first light can be emitted to the outer side of the OLED display away from the optical fingerprint module 101, and reflected after passing through the object to be scanned. Different objects to be scanned have different shapes or colors, and the energy of the reflected second light is also different, thus resulting in different grayscale images.

本发明实施例提供的扫描方法，在接收到用户的扫描输入后，可控制OLED显示屏103向外发出第一光线，通过光学指纹模组对接收的第二光线进行光电转换得到灰度图像，第二光线为第一光线经过待扫描对象后反射至光学指纹模组的反射光线。由于在扫描过程中，是利用OLED显示屏103向外发出第一光线，通过光学指纹模组对接收的第一光线经过待扫描对象反射的第二光线进行光电转换得到灰度图像，实现对待扫描对象的扫描，不再通过摄像头进行扫描，可避免摄像头镜头的限制，提高扫描得到的灰度图像的准确性。而且，利用OLED显示屏103以及光学指纹模组进行扫描过程中，由于光学指纹模组近距离(接近0)的焦距以及大面积为指纹接收区的特点，可减小扫描失真，扫描精度可达到几十um，甚至um级别。而且无需额外增加成本，便捷且快速。The scanning method provided by the embodiment of the present invention can control theOLED display screen 103 to emit the first light outward after receiving the scanning input from the user, and the optical fingerprint module can photoelectrically convert the received second light to obtain a grayscale image. The second light is the reflected light that is reflected to the optical fingerprint module after the first light passes through the object to be scanned. During the scanning process, theOLED display screen 103 is used to send out the first light, and the optical fingerprint module performs photoelectric conversion on the received first light and the second light reflected by the object to be scanned to obtain a grayscale image, realizing the The scanning of the object is no longer performed by the camera, which can avoid the limitation of the camera lens and improve the accuracy of the grayscale image obtained by scanning. Moreover, during the scanning process using theOLED display 103 and the optical fingerprint module, due to the short-distance (close to 0) focal length of the optical fingerprint module and the characteristics of a large area as a fingerprint receiving area, scanning distortion can be reduced, and the scanning accuracy can reach Dozens of um, even um level. And without additional cost, convenient and fast.

在一个实施例中，基于光学指纹模组对接收的第二光线进行光电转换得到灰度图像，包括：基于光学指纹模组对接收的第二光线进行N次光电转换，得到N个灰度图像，N为正整数；对N个灰度图像进行合成得到目标灰度图像。即如图3所示，本实施例提供一种扫描方法，应用于上述电子设备，电子设备包括光学指纹模组以及OLED显示屏，光学指纹模组位于OLED显示屏下方，该方法包括：In one embodiment, performing photoelectric conversion on the received second light based on the optical fingerprint module to obtain a grayscale image includes: performing N times of photoelectric conversion on the received second light based on the optical fingerprint module to obtain N grayscale images , N is a positive integer; the target grayscale image is obtained by synthesizing N grayscale images. That is, as shown in Figure 3, this embodiment provides a scanning method, which is applied to the above-mentioned electronic equipment. The electronic equipment includes an optical fingerprint module and an OLED display. The optical fingerprint module is located below the OLED display. The method includes:

步骤301：接收用户的扫描输入；Step 301: Receive user's scanning input;

步骤302：响应于扫描输入，控制OLED显示屏向外发出第一光线。Step 302: In response to the scan input, control the OLED display to emit a first light.

优先地，可控制OLED显示屏向OLED显示屏远离光学指纹模组的一侧发出第一光线。Preferably, the OLED display screen can be controlled to emit the first light to the side of the OLED display screen away from the optical fingerprint module.

步骤303：基于光学指纹模组对接收的第二光线进行N次光电转换，得到N个灰度图像。Step 303: Perform N times of photoelectric conversion on the received second light based on the optical fingerprint module to obtain N grayscale images.

N为正整数，第二光线为第一光线经过待扫描对象后反射至光学指纹模组的反射光线。N is a positive integer, and the second light is a reflected light that is reflected to the optical fingerprint module after the first light passes through the object to be scanned.

步骤304：对N个灰度图像进行合成得到目标灰度图像。Step 304: Synthesize the N grayscale images to obtain a target grayscale image.

步骤301-302与上述步骤201-202一一对应，不再赘述。Steps 301-302 correspond to the above-mentioned steps 201-202 one by one, and will not be repeated here.

在本实施例中，在接收用户的扫描输入后，可进行N次的扫描，每一次扫描过程中，接收一次第二光线，进行一次光电转换，如此，可得到N个灰度图像。然后对N个灰度图像进行合成得到目标灰度图像。如此，即便待扫描对象体积较大，也能通过N次扫描得到N个灰度图像，并进行合成得到目标灰度图像，确保目标灰度图像的完整，使扫描得到的目标灰度图像能准确体现待扫描对象。In this embodiment, after receiving the scanning input from the user, N times of scanning can be performed. During each scanning process, the second light is received once, and photoelectric conversion is performed once. In this way, N grayscale images can be obtained. Then synthesize the N grayscale images to obtain the target grayscale image. In this way, even if the volume of the object to be scanned is large, N grayscale images can be obtained through N times of scanning, and the target grayscale image can be synthesized to ensure the integrity of the target grayscale image, so that the scanned target grayscale image can be accurately Indicates the object to be scanned.

在一个实施例中，控制OLED显示屏向外发出第一光线，包括：控制OLED显示屏向外发出N次第一光线；In one embodiment, controlling the OLED display to emit the first light outwards includes: controlling the OLED display to emit the first light N times;

基于光学指纹模组对接收的第二光线进行N次光电转换，得到N个灰度图像，包括：基于光学指纹模组对每一次接收到的第二光线进行光电转换，得到N个灰度图像。Based on the optical fingerprint module, the received second light is photoelectrically converted N times to obtain N grayscale images, including: based on the optical fingerprint module, photoelectric conversion is performed on each received second light to obtain N grayscale images .

在进行N次扫描过程中，可控制OLED显示屏向外发出N次第一光线，每扫描一次，控制发出一次第一光线，则会反射一次第二光线，即光学指纹模组会接收N次第二光线。如此，可减少OLED显示屏的发光时间，节省电能。光学指纹模组每次接收到第二光线，即可对其进行光电转换，如此，可实现对反射的N次第二光线进行光电转换，从而得到N个灰度图像。In the process of scanning N times, the OLED display can be controlled to send out the first light N times. Every time it is scanned, the first light is controlled to be emitted once, and the second light will be reflected once, that is, the optical fingerprint module will receive N times. second light. In this way, the light-emitting time of the OLED display can be reduced and power can be saved. Each time the optical fingerprint module receives the second light, it can perform photoelectric conversion on it. In this way, it can realize photoelectric conversion on N times of reflected second light, so as to obtain N grayscale images.

在一个示例中，可根据预设间隔时长或预设距离，控制OLED显示屏向外发出N次第一光线。即每两个相邻的第一光线之间的发出时间间隔时长为预设间隔时长，即电子设备每间隔预设间隔时长进行一次第一光线的发出，实现一次扫描。或者每两个相邻的第一光线对应的电子设备所在位置之间的距离为预设距离，即电子设备每移动预设距离进行一次第一光线的发出，实现一次扫描，以满足对多次扫描的需求。In an example, the OLED display screen may be controlled to emit the first light N times outward according to a preset interval or a preset distance. That is, the emission time interval between every two adjacent first light rays is the preset interval length, that is, the electronic device emits the first light rays once every preset interval length to realize one scan. Or the distance between the positions of the electronic devices corresponding to every two adjacent first light rays is a preset distance, that is, the electronic device sends out the first light rays once every time the electronic device moves a preset distance, so as to realize one scan to satisfy multiple scanning needs.

在一个实施例中，基于光学指纹模组对接收的第二光线进行光电转换得到灰度图像，还包括：在完成一次光电转换之后，输出提示信息。In one embodiment, the photoelectric conversion of the received second light based on the optical fingerprint module to obtain the grayscale image further includes: outputting prompt information after one photoelectric conversion is completed.

每完成一次光电转换可得到一个灰度图像，则表示完成一次扫描，则在完成次光电转换之后，可输出提示信息，以提示完成一次扫描，以便用户查看以及了解扫描情况。例如，提示信息可以是语音提示信息或/和文字提示信息等。A grayscale image can be obtained every time a photoelectric conversion is completed, which means that a scan is completed, and after the photoelectric conversion is completed, a prompt message can be output to prompt the completion of a scan, so that the user can view and understand the scanning situation. For example, the prompt information may be voice prompt information or/and text prompt information.

在一个实施例中，对N个灰度图像进行合成得到目标灰度图像，包括：In one embodiment, the target grayscale image is obtained by synthesizing N grayscale images, including:

在N个灰度图像不同的情况下，基于N个灰度图像对应的位置信息，对N个灰度图像进行拼接得到目标灰度图像；In the case where the N grayscale images are different, based on the position information corresponding to the N grayscale images, the N grayscale images are spliced to obtain a target grayscale image;

在N个灰度图像相同的情况下，对N个灰度图像进行图像融合处理，得到目标灰度图像。In the case that the N grayscale images are the same, image fusion processing is performed on the N grayscale images to obtain the target grayscale image.

在N个灰度图像不同的情况下，表示在扫描过程中电子设备有移动，对待扫描对象的不同区域进行了扫描，如此，可基于N个灰度图像对应的位置信息，对N个灰度图像进行拼接得到目标灰度图像。其中，位置信息可以理解为在得到灰度图像时电子设备所在的位置。通过N个灰度图像对应的位置信息，对N个灰度图像进行拼接得到目标灰度图像，可确保拼接的准确性，从而提高目标灰度图像的准确性。在一个示例中，可通过传感器记录电子设备的位置，例如，重力传感器等。In the case where the N grayscale images are different, it means that the electronic device has moved during the scanning process, and different areas of the object to be scanned have been scanned. In this way, based on the position information corresponding to the N grayscale images, the N grayscale The images are spliced to obtain the target grayscale image. Wherein, the location information can be understood as the location of the electronic device when the grayscale image is obtained. According to the position information corresponding to the N gray-scale images, the N gray-scale images are spliced to obtain the target gray-scale image, which can ensure the accuracy of splicing, thereby improving the accuracy of the target gray-scale image. In one example, the location of the electronic device may be recorded by a sensor, such as a gravity sensor or the like.

另外，在N个灰度图像相同的情况下，表示N个灰度图像为电子设备在同一位置进行光电转换得到的灰度图像或特征信息相同，则对N个灰度图像进行图像融合处理，得到目标灰度图像。In addition, in the case that the N grayscale images are the same, it means that the N grayscale images are grayscale images obtained by photoelectric conversion at the same position of the electronic device or the feature information is the same, then image fusion processing is performed on the N grayscale images, Get the target grayscale image.

在一个示例中，可基于N个灰度图像对应的位置信息或N个灰度图像的特征信息，检测N个灰度图像是否相同，若N个灰度图像对应的位置信息相同，则表示电子设备在同一个位置进行了多次光电转换，得到的N个灰度图像相同。若N个灰度图像的特征信息相同，则表示N个灰度图像相同。通过该方式能准确检测N个灰度图像是否相同，以提高得到的目标图像的精确性。In an example, based on the position information corresponding to the N gray-scale images or the feature information of the N gray-scale images, it can be detected whether the N gray-scale images are the same. If the position information corresponding to the N gray-scale images is the same, it means that the electronic The device performs multiple photoelectric conversions at the same position, and the obtained N grayscale images are the same. If the feature information of the N grayscale images is the same, it means that the N grayscale images are the same. In this manner, it can be accurately detected whether the N grayscale images are the same, so as to improve the accuracy of the obtained target image.

下面以一个具体实施例对的上述扫描方法加以具体说明。The above-mentioned scanning method will be described in detail below with a specific embodiment.

如图1所示，以待扫描对象104为表面不平整(例如，存在脊和谷)的物体为例，通过感应待扫描对象104的突出部分(脊)和凹陷部分(谷)反射光源能量的差异，从而形成不同灰度的图像，实现平整度检查，微裂缝探伤，脉络拓印，碑文无纸拓印功能。首先进入光电指纹脊谷模式，将电子设备靠近待扫描对象，将待扫描对象104紧贴电子设备的OLED显示屏103远离光学指纹模组101的一侧。通过按侧键或其他方式，开启扫描，控制OLED显示屏103中的OLED发光二极管102点亮，向外发出第一光线，即实现OLED显示屏103向外发出第一光线。第一光线到待扫描对象的表面，第一光线产生反射。反射的第二光线达到光学指纹模组101。不同的脊和谷，反射回来的第二光线的能量有差异，进行光电转换，即可生成灰度图像。后续可输出第二提示信息，以提示用户扫描完成。后续可将得到的灰度图像传递给电子设备中后端进行分析处理，例如，进行平整度分析、微裂缝分析、植物脉络拓印、碑文拓印等。在一个示例中，电子设备还包括玻璃盖板105，置于OLED显示屏103的一侧，待扫描对象104可置于玻璃盖板105远离OLED显示屏103的一侧。通过玻璃盖105可对OLED显示屏起到保护作用。可将电子设备靠近待扫描对象104，使待扫描对象104可紧贴电子设备的玻璃盖板105远离OLED显示屏103的一侧。通过用户的扫描输入，开启扫描。As shown in FIG. 1 , taking theobject 104 to be scanned as an object with an uneven surface (for example, there are ridges and valleys) as an example, by sensing the protruding parts (ridges) and concave parts (valleys) of the object to be scanned 104 to reflect the energy of the light source Differences, thereby forming images of different gray levels, realizing the functions of flatness inspection, micro-crack flaw detection, vein rubbing, and inscription rubbing. First enter the photoelectric fingerprint ridge-valley mode, put the electronic device close to the object to be scanned, and put theobject 104 to be scanned against the side of theOLED display 103 of the electronic device away from the optical fingerprint module 101 . By pressing the side key or other methods, the scanning is started, and the OLED light-emittingdiode 102 in theOLED display 103 is controlled to light up to emit the first light, that is, theOLED display 103 emits the first light. The first light rays hit the surface of the object to be scanned, and the first light rays are reflected. The reflected second light reaches the optical fingerprint module 101 . For different ridges and valleys, the energy of the reflected second light is different, and the grayscale image can be generated by photoelectric conversion. Subsequently, a second prompt message may be output to prompt the user that the scanning is completed. Subsequently, the obtained grayscale image can be transmitted to the backend of the electronic device for analysis and processing, for example, for flatness analysis, micro-crack analysis, plant vein rubbing, inscription rubbing, etc. In one example, the electronic device further includes aglass cover 105 placed on one side of theOLED display 103 , and theobject 104 to be scanned can be placed on a side of theglass cover 105 away from theOLED display 103 . The OLED display screen can be protected by theglass cover 105 . The electronic device can be placed close to the object to be scanned 104 so that the object to be scanned 104 can cling to the side of theglass cover 105 of the electronic device away from theOLED display screen 103 . Scanning is started by the user's scan input.

若待扫描对象104体积较大，可对其进行N次第一光线的发出，进行N次光电转换，得到N个灰度图像，在对N个灰度图像进行合成得到目标灰度图像。具体地，首先，进入光电指纹脊谷模式。通过按侧键或其他方式，开启扫描。If the volume of theobject 104 to be scanned is large, N times of first light emission and N times of photoelectric conversion can be performed on it to obtain N grayscale images, and then the N grayscale images are synthesized to obtain a target grayscale image. Specifically, first, enter the photoelectric fingerprint ridge-valley mode. Start scanning by pressing the side button or other methods.

扫描一次(即光电转换一次)，产生一个灰度图像，并通过传感器记录该灰度图像的位置信息。产生扫描提示音即提示信息，以提示用户完成一次扫描。扫描第N次，产生第N个灰度图像，记录位置信息，如此，可得到N个灰度图像。按侧键或其他方式触发，结束扫描。根据位置信息或图像特征分析N个灰度图像是否相同，若分析为相同的图像，则将N个灰度图像直接融合，可产生清晰度高的目标灰度图像。可将得到的清晰度高的目标灰度图像传递给给后端进行平整度分析、微裂缝分析、植物脉络拓印、碑文拓印等。Scanning once (that is, photoelectric conversion once), a grayscale image is generated, and the position information of the grayscale image is recorded by the sensor. Generate a scanning prompt tone, that is, a prompt message, to prompt the user to complete a scan. The Nth grayscale image is generated by scanning for the Nth time, and the position information is recorded. In this way, N grayscale images can be obtained. Press the side button or other triggers to end the scan. According to the location information or image features, analyze whether the N grayscale images are the same. If the analysis is the same image, then directly fuse the N grayscale images to generate a high-definition target grayscale image. The obtained high-definition target grayscale image can be passed to the back-end for flatness analysis, micro-crack analysis, plant vein rubbing, inscription rubbing, etc.

若分析为不相同的图像，则可根据位置信息和相邻图片重叠部分信息，进行拼接，生成完整的目标灰度图像。完整的目标灰度图像给后端进行平整度分析、微裂缝分析、植物脉络拓印、碑文拓印等。If it is analyzed as different images, it can be spliced according to the position information and the overlapping information of adjacent pictures to generate a complete target grayscale image. The complete target grayscale image is used for back-end flatness analysis, micro-crack analysis, plant vein rubbing, inscription rubbing, etc.

以待扫描对象104为表面平整(例如，文档)的物体为例，如图4所示，深色(如黑色)区域会吸收较多的能量，反射的能量会减少较多，浅色(如白色)区域吸收能量非常少，反射的能量多。通过感应待扫描对象的颜色反射的光线的能量的差异(即不同的颜色吸收能量有差异，反射回来的能量有差异，光电转换，产生灰度原始图像)，从而形成不同的灰度的图像。实现文档扫描、识别二维码以及识别条形码等功能。Taking theobject 104 to be scanned as an object with a flat surface (for example, a document) as an example, as shown in FIG. White) areas absorb very little energy and reflect more energy. By sensing the difference in the energy of light reflected by the color of the object to be scanned (that is, different colors absorb energy differently and reflect back energy differently, photoelectric conversion produces a grayscale original image), thereby forming different grayscale images. Realize functions such as document scanning, QR code recognition and barcode recognition.
