In addition, the server 100 may be a cloud server or a traditional server, the camera 200 may be a gun camera, a hemisphere camera, a high-definition smart sphere camera, a pen container camera, a single-board camera, a flying saucer camera, a mobile phone camera, etc., and the lens of the camera may be a wide-angle lens, a standard lens, a telephoto lens, a zoom lens, a pinhole lens, etc., and is not limited herein.
In some embodiments, the plurality of cameras 200 are disposed at different positions for photographing different areas, and photographing areas of each two adjacent cameras 200 of the plurality of cameras 200 are adjacent or partially coincide. It can be understood that each camera 200 can correspondingly shoot different areas according to the difference of the angle of view and the setting position, and the shooting areas of every two adjacent cameras 200 are arranged to be adjacent or partially overlapped, so that the area to be shot by the distributed system can be completely covered. The plurality of cameras 200 may be arranged side by side at intervals in a length direction, and configured to capture images in the length direction area, or the plurality of cameras 200 may also be arranged at intervals in a ring direction, and configured to capture images in the ring area, and of course, the plurality of cameras 200 may further include other arrangement modes, which are not limited herein.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an image processing method according to an embodiment of the present application. The image processing method is used for monitoring and shooting through a plurality of cameras distributed at different positions, then grouping the shot images of the cameras according to different differences, removing designated contents of the shot images in the grouping, splicing and synthesizing the shot images according to the grouped shot images to form video files corresponding to different moving objects, removing the designated contents from the video files, reducing the interference of the designated contents to users, and facilitating the viewing of the users. In a specific embodiment, the image processing method is applied to the image processing apparatus 400 shown in fig. 7 and the server 100 (fig. 11) configured with the image processing apparatus 400. The specific flow of the embodiment will be described below by taking a server as an example, and it is understood that the server applied in the embodiment may be a cloud server, and may also be a traditional server, which is not limited herein. The multiple cameras are distributed at different positions, and shooting areas of two adjacent cameras in the multiple cameras are adjacent or partially overlapped. As will be described in detail with respect to the flow shown in fig. 2, the image processing method may specifically include the following steps:
step S110: and acquiring shot images of the plurality of cameras.
In the embodiment of the application, the plurality of cameras distributed at different positions can shoot the shooting areas, and each camera can shoot the shot image of the corresponding shooting area. The plurality of cameras can upload shot images to the server, and the server can receive shot images uploaded by the plurality of cameras. The plurality of cameras are distributed at different positions, and the shooting areas of two adjacent cameras are adjacent or partially overlapped, so that the server can acquire the shooting images of different shooting areas, and the shooting areas can form a complete area, namely, the server can acquire the shooting image of a large-range complete area. The method for uploading the shot images by the camera is not limited, and for example, the shot images may be uploaded according to a set interval duration.
In some embodiments, each of the plurality of cameras may be in an on state, so that the entire shooting area corresponding to the plurality of cameras may be shot, wherein each of the plurality of cameras may be in an on state at a set time period or all the time. Of course, each camera in the multiple cameras may also be in an on state or an off state according to the received control instruction, and the control instruction may include an instruction automatically sent by a server connected to the camera, an instruction sent by the electronic device to the camera through the server, an instruction generated by a user through triggering the camera, and the like, which is not limited herein.
Step S120: and according to moving objects existing in the shot images, grouping the shot images of the multiple cameras according to different moving objects to obtain multiple first image groups, wherein the first image groups are a set of shot images containing the same moving object, and the moving objects corresponding to the first image groups are different.
In the embodiment of the application, after acquiring the shot images of the multiple cameras, the server can acquire the moving object existing in the shot images. The moving object may be a movable object such as a person, an animal, or a vehicle, and is not limited herein. In some embodiments, the server may identify the moving object in the captured image through feature information of the moving object, for example, the server may identify a moving person or a moving animal through facial features, body type features, and the like, and may identify a moving vehicle through vehicle features (license plate, vehicle color, vehicle type, and the like), which is not limited herein.
After acquiring the moving object in the captured images, the server may obtain captured images in which the moving object exists in the captured images of the plurality of cameras. The server can group the shot images with the moving objects in the shot images of the cameras in real time according to different moving objects to obtain a plurality of first image groups, wherein the plurality of first image groups correspond to the plurality of moving objects one to one, namely each first image group corresponds to different moving objects. Thus, the server can obtain all the photographed images of the moving object photographed. It is understood that since a plurality of moving objects may exist in the captured images, the same moving object may exist in the captured images of different first image groups.
For example, referring to fig. 3, when the moving object includes object 1, object 2, and object 3, and object 1, object 2, and object 3 move in different camera areas, the cameras in the corresponding areas capture images, and the captured images corresponding to object 1, object 2, and object are grouped, so that an image group corresponding to object 1, an image group corresponding to object 2, and an image group corresponding to object 3 can be obtained.
Step S130: when a removal instruction for removing specified content from at least one captured image of the first image group is received, the specified content existing in the captured image of the at least one first image group is removed, and at least one second image group is obtained.
In the embodiment of the application, the server may receive a removal instruction sent by the electronic device, where the removal instruction is used to instruct the server to specify content in the captured images of the at least one first image group.
In some embodiments, the user sends the removal instruction to the server through the electronic device, so as to meet the requirement that the user wants to remove the specified content in the captured image of a certain first image group, so that the specified content is not contained in the video file obtained according to the first image group later.
In some embodiments, the removal instruction received by the server may carry the selected at least one first image group and the specified content to be removed, where the specified content may include the target person, the target object, the target background, and the like.
In some embodiments, the server may determine, according to the received removal instruction, at least one first image group required by the user to remove the specified content, and determine specific content of the specified content. The server may perform removal of the specified content for the captured image in the at least one first image group based on the determined at least one first image group and the specified content. The server can identify the designated content of each captured image in the first image group when the designated content existing in the captured image of at least one first image group is removed, and if the designated content exists in the captured image, the designated content in the captured image is removed, so that the server can remove the designated content existing in the captured image of the first image group after the operation is performed on each image of the first image group. The server may identify the designated content according to feature information of the designated content, image content, and the like, which is not limited herein.
In some embodiments, the removing of the designated content in the captured image may include: and cutting the specified content in the shot image or blurring the specified content. The blurring of the designated content may be, but is not limited to, reducing the sharpness, brightness, etc. of the designated content.
Step S140: and splicing and synthesizing the shot images of the at least one second image group according to the shooting time sequence of the shot images to obtain a video file corresponding to the at least one moving object.
In this embodiment of the application, after obtaining the second image group corresponding to the mobile object, the server may perform stitching synthesis on the captured images in the at least one image group according to the order of the capturing time of the captured images, so as to obtain the video file corresponding to the at least one mobile object.
In some embodiments, the server may acquire the photographing time of the photographed image from the stored file information of the photographed image. The camera can send the shooting time to the server as one of the description information of the shot images when uploading the shot images, so that the server can obtain the shooting time of the shot images when receiving the shot images. Of course, the manner in which the server acquires the shooting time of the shot image is not limited, and for example, the server may search for the shooting time of the shot image from the camera.
In some embodiments, the server may sort the shooting times of all the shot images in each second image group from first to last, so as to obtain the sequence of the shooting times. And then according to the sequence, all the shot images of the second image group are spliced and synthesized to obtain the video file of the moving object corresponding to the second image group. That is, the captured images in the second image group constitute each frame of image in the video file, and the order of the images in the video file is the same as the order of the capturing time.
In some embodiments, the server may also send the video file to an electronic device or a third-party platform (e.g., APP, web mailbox, etc.) for convenient viewing and downloading by the user, so that the user can directly view the video formed by the captured images of the moving object.
In addition, because time is needed for moving the moving object from one shooting area to another shooting area, different cameras can shoot the moving object in sequence, so that the shooting time for shooting images has a sequence, and the behavior track of the moving object in the shooting area formed by the cameras can be reflected in the video spliced and synthesized by the server according to the sequence of the shooting time. And because the shooting areas of two adjacent cameras in the cameras are adjacent or partially overlapped, the shooting area formed by the cameras is a complete area, and therefore the spliced and synthesized video file can reflect the activity change of the content of a moving object in a larger area.
According to the image processing method provided by the embodiment of the application, shot images shot by a plurality of cameras distributed at different positions are grouped according to the moving object degree of the shot images, then a removal instruction for removing specified contents of the shot images in at least one grouped image is received, and based on the instruction, after the specified contents of the shot images in at least one group are removed, the shot images in the group are spliced and synthesized according to the shot images in the group, so that video files corresponding to different moving objects are formed, the monitoring effect is improved, the specified contents in the video files are removed, the interference of the specified contents to users is avoided, the users do not need to check the shot images in all shooting areas independently, and the user experience is prompted.
Referring to fig. 4, fig. 4 is a flowchart illustrating an image processing method according to another embodiment of the present application. The method is applied to the server, the server is in communication connection with a plurality of cameras, the cameras are distributed at different positions, and shooting areas of two adjacent cameras in the cameras are adjacent or partially overlapped.

Therefore, the server can determine the shot image with at least one human face from the shot images of the plurality of cameras, so as to obtain the shot image with at least one moving object in the shot images of the plurality of cameras.
After obtaining the captured images of at least one moving object in the captured images of the plurality of cameras, the server may group all the captured images with at least one moving object according to different moving objects to obtain a plurality of first image groups, where the first image groups are a set of captured images including the same moving object, and the moving objects corresponding to each of the first image groups are different.
Step S230: and sending at least one shot image of each of the plurality of first image groups to the electronic device.
In some embodiments, after obtaining the plurality of first image groups, the server may select at least one captured image from each of the plurality of first image groups, and then send the at least one captured image corresponding to each of the plurality of first image groups to the electronic device, so that a user corresponding to the electronic device selects at least one first image group from which specified content needs to be removed and selects specified content from the captured images which needs to be removed, and when the selected first image groups are multiple, different specified content may be selected for different first image groups. The user can select a target area in the shot image, and the content of the target area is used as the designated content selected by the user.
In some embodiments, at least one captured image is selected from each of the plurality of first image groups, and the selection may be performed according to a set rule. As an embodiment, the captured image selected according to the setting rule may be an image of the first image group when the moving object is at an intermediate position of the capturing area. Of course, the specific setting rule may not be limiting.
After receiving the at least one captured image corresponding to each first image group, the electronic device may display a selection interface for selecting the removed content according to the at least one captured image of each first image group in the plurality of first image groups, so that a user selects the first image group, and selects a target area from the at least one captured image corresponding to the selected first image group, where the content of the target area is used as the selected designated content. And the electronic equipment can generate a removal instruction according to the at least one first image group selected by the user and the selected specified content, and send the removal instruction to the server. Therefore, after the user views at least one shot image in each first image group, the user can select at least one first image group needing to remove the specified content and the specified content needing to be removed, and the user experience is improved.
Step S240: and receiving a removal instruction sent by the electronic equipment, wherein the removal instruction is sent by the electronic equipment when the selection interface for selecting the removal content is detected to select the content of the target area in the shot image corresponding to at least one first image group in the selection interface after the selection interface for selecting the removal content is displayed according to at least one shot image of each first image group in the plurality of first image groups.
In some embodiments, after receiving the removal instruction, the server may obtain, according to the removal instruction, at least one first image group selected by the user and the specified content, where the specified content is content of the selected target area in the captured image corresponding to the first image group.
Step S250: and responding to the removal instruction, and identifying the content of the target area to obtain the characteristic information of the content of the target area.
In some embodiments, after obtaining the removal instruction, the server may identify the content of the target area to obtain feature information of the content of the target area, where the feature information may be an image feature. For example, when the content of the target area is a person, the feature information may be a face feature, a body shape feature, or the like, and when the content of the target area is an object, the feature information may be an appearance feature of the object, or the like, which is not limited herein.
Step S260: and removing the content matched with the characteristic information in each shot image of the at least one first image group based on the characteristic information to obtain at least one second image group.
After the server identifies the feature information of the target area selected by the user, each shot image can be matched with the feature information, and the shot image with the content matched with the feature information is determined. The server may then remove the content matching the feature information in the captured image for the captured image in which the content matching the feature information exists. The server can obtain at least one second image group after processing each shot image of the at least one first image group.
Step S270: and splicing and synthesizing the shot images of the at least one second image group according to the shooting time sequence of the shot images to obtain a video file corresponding to the at least one moving object.

For example, the shooting area 1, the shooting area 2, the shooting area 3, and the shooting area 4 are adjacent in sequence, and if the designated area selected by the user is the shooting area 1, the shooting area 3, and the shooting area 4, the designated area is the intermittent shooting area 2, and thus the designated area selected by the user is not a continuous area.
Further, if the server determines that the designated area selected by the user is not a continuous area, prompting content for prompting the user that the designated area is discontinuous may be sent to the electronic device, so that the user may reselect the designated area. It can be understood that, generally, a user needs to view a moving video of a moving object in a continuous area, and if the specified area is not a continuous area, the requirement of the user cannot be met, so that the prompt content is sent to prompt the user, and the user can conveniently select the continuous area as the specified area.
Of course, the user may also send an instruction to the server to determine the selected designated area (non-continuous area) through the electronic device, and the server may perform the screening of the captured image according to the currently selected designated area.
In some embodiments, the images shot by the camera in the designated area and the images shot in the designated time period can be used as the screening conditions at the same time, so that the moving video of the moving object in the shooting area and the time period required to be viewed by the user can be obtained conveniently. Of course, the specific screening conditions may not be limiting.
Step S322: and according to moving objects existing in the shot images meeting the screening conditions, grouping the shot images meeting the screening conditions according to different moving objects to obtain a plurality of first image groups.
After the captured images of the plurality of cameras are screened, the captured images meeting the screening condition may be grouped according to different moving objects according to the screened captured images, so as to obtain a plurality of first image groups.
Step S330: a plurality of types of contents in which the captured image of each of the plurality of first image groups exists are identified.
In the embodiment of the present application, the server may identify a plurality of types of contents in which the captured image of each of the plurality of first image groups exists. Wherein the plurality of types of content may include: people, articles, animals, plants, etc., without limitation.
Step S340: and sending the plurality of types of content corresponding to each first image group in the plurality of first image groups to the electronic equipment.
After obtaining the multiple types of content existing in the captured image of each first image group in the first image group, the server may send the multiple types of content corresponding to each first image group to the electronic device, so that the electronic device displays a selection interface for selecting to remove the content according to the multiple types of content, where the selection interface includes the multiple types of content corresponding to each first image group, and thus, a user may select, according to the selection interface, the first image group from which the specified content needs to be removed and at least one type of content in the first image group that needs to be removed.
Step S350: and receiving a removal instruction sent by the electronic equipment, wherein the removal instruction is sent by the electronic equipment when the selection operation of the appointed type content corresponding to at least one first image group in the selection interface is detected after the selection interface for selecting the removal content is displayed according to the plurality of types of content corresponding to each first image group in the plurality of first image groups.
In some embodiments, after receiving the removal instruction, the server may obtain, according to the removal instruction, at least one first image group selected by the user and the specified type of content that needs to be removed.
Step S360: and in response to the removal instruction, removing the specified type of content existing in each captured image of the at least one first image group to obtain at least one second image group.
In some embodiments, the server may identify a specified type of content present in each captured image of the first image group and then remove the specified type of content present in each captured image, thereby obtaining the second image group with the specified type of content removed. The server may identify whether the specific type of content exists in the captured image according to the feature information of the specific type of content, for example, when the specific type of content is a vehicle type of content, the captured image may be identified according to the feature information of the vehicle, and if content matching the feature information of the vehicle exists in the captured image, it is determined that the vehicle type of content exists in the captured image.
In some embodiments, before removing the specified content present in the captured image of at least one of the first image groups, the method may further include:
judging that the number of target shooting images in the at least one first image group is smaller than a first set threshold value, wherein the target shooting images are shooting images with the appointed content; if the first set threshold value is smaller than the first set threshold value, sending prompt content to the electronic equipment, wherein the prompt content is used for prompting whether the specified content existing in the shot image of the at least one first image group is removed; upon receiving the determination instruction, then performing removal of the specified content present in the captured image of at least one of the first image groups.
In some embodiments, when the number of the target captured images is not greater than the first image group with the first set threshold, the user may not be disturbed, so that the user may be prompted to determine whether to perform the removal of the designated content for the first image group with the number of the target captured images not greater than the first set threshold.
When the number of the target captured images is larger than the first set threshold, the captured images indicating that the designated content exists in the first target image group are more, and the interference to the user is highly likely to be caused, so that the server can remove the designated content from the first image group in which the number of the target captured images is larger than the first set threshold. The first image group is screened by using the removing conditions, so that the number of the first image groups with the appointed contents removed by the server can be reduced, and the processing efficiency of the server is improved.
Step S370: and splicing and synthesizing the shot images of the at least one second image group according to the shooting time sequence of the shot images to obtain a video file corresponding to the at least one moving object.
In some embodiments, after obtaining the plurality of second image groups, the server may further filter the captured images in the second image group corresponding to each moving object before performing stitching synthesis on the captured images in each of the plurality of second image groups.
As an embodiment, the server may determine whether the second image group includes captured images of two adjacent cameras at the same time on the moving object; if the second image group comprises images shot by two adjacent cameras at the same time for the moving object, acquiring a first target image shot by a first camera in the two adjacent cameras at the same time and acquiring a second target image shot by a second camera in the two adjacent cameras at the same time; and screening an image with the optimal image quality parameter of the moving object from the first target image and the second target image.
In this embodiment, the areas shot by two adjacent cameras partially overlap, so when the moving object is located in the overlapping portion of the areas shot by the two adjacent cameras, the two adjacent cameras may shoot the moving object at the same time, and therefore the captured image acquired by the server includes two captured images including the moving object and shot at the same time. Therefore, a target image (referred to as a first target image) captured by a first camera (one of the two adjacent cameras) at the same time and a target image (referred to as a second target image) captured by a second camera (the other camera) at the same time can be acquired.
Further, after acquiring the first target image and the second target image, the server may acquire an image quality parameter of the moving object in the first target image (denoted as a first image quality parameter) and an image quality parameter of the moving object in the second target image (denoted as a second image quality parameter), respectively. The image quality parameters may include sharpness, brightness, sharpness, lens distortion, color, resolution, color gamut, purity, and the like, which are not limited herein.
After obtaining the first image quality parameter and the second image quality parameter, the server may compare image quality effects corresponding to the first image quality parameter and the second image quality parameter, obtain an optimal image quality parameter from the first image quality parameter and the second image quality parameter according to a comparison result, and then screen an image corresponding to the optimal image quality parameter from the first target image and the second target image. For example, when the image quality parameter includes a sharpness, an image corresponding to the highest sharpness may be obtained from the first target image and the second target image.
After the server performs the image screening on each second image group, the server may perform stitching and synthesizing on the captured images of each second image group subjected to the image screening to obtain video files corresponding to a plurality of moving objects.
In some embodiments, after the video files corresponding to the plurality of mobile objects are acquired, the server may send the video files corresponding to the plurality of mobile objects to the electronic device. As one way, the server may send video files corresponding to a plurality of moving objects to the same electronic device. As another mode, the video file corresponding to each moving object is sent to the electronic device corresponding to each moving object.

It can be understood that, in the video file corresponding to a certain obtained moving object, there may be contents of other moving objects, and the other moving objects are also contents of interest to the user. Therefore, it is possible to determine whether the video file corresponding to the moving object includes the content of the other moving object by determining whether the second image group corresponding to the moving object includes the captured image of the other moving object.
Further, if at least the shot images of other moving objects exist in the second image group corresponding to the first moving object, the server may send the prompting content to the electronic device while sending the video files corresponding to the plurality of moving objects to the electronic device, so that the user may be prompted that the contents of other moving objects exist in the video file corresponding to the first moving object.
In some embodiments, the server may also mark other mobile objects in the video file, facilitating the user to view the other mobile objects in the video file. For example, in a scene for police to check evidence, if the content of the suspect B exists in the video file corresponding to the victim a, the content of the suspect B is marked, so that the police can conveniently and quickly find out the video evidence.
Of course, the above embodiment may also be applied to the foregoing embodiment, that is, the above-described manner of determining whether the video file corresponding to the moving object has the content of another moving object, and sending the prompt content may also be applied to the foregoing embodiment.
In some embodiments, the image processing method may also be applied to monitoring a scene of a moving object. The video file corresponding to the mobile object obtained by the server can be used as a monitoring video corresponding to the mobile object, and the server can send the monitoring video to the monitoring terminal corresponding to the mobile object, so that a user corresponding to the monitoring terminal can know the activity condition of the mobile object in time. For example, the mobile object may be an old person or a child, and the monitoring terminal may correspond to a guardian of the old person or the child, so that the guardian can timely know the condition of the old person or the child at home, and the occurrence of an accident is avoided.
Further, after the server obtains the monitoring video of the mobile object, the server can automatically analyze the monitoring video to judge whether the mobile object in the monitoring video is abnormal, and when the judgment result represents that the mobile object is abnormal, alarm information can be sent to the monitoring terminal corresponding to the mobile object, so that a user corresponding to the monitoring terminal can timely perform corresponding processing. The abnormal condition may include falling, lying down, crying, onset of disease, etc., which is not limited herein. In addition, when the server sends the alarm information to the monitoring terminal, the server can also send the monitoring video or the video clip corresponding to the abnormal condition to the monitoring terminal, so that a user corresponding to the monitoring terminal can know the real condition of the mobile object in time.
In some embodiments, after receiving the monitoring video sent by the server, the monitoring terminal may send target instruction information to the server based on the monitoring video, and accordingly, after receiving the target instruction information, the server performs a corresponding operation in response to the target instruction information, for example, dialing an alarm call, dialing an emergency call, and the like.
