technical field

The embodiments of the present application relate to the field of cameras, and in particular, to a method for debugging a camera and related equipment.

Background technique

With the rapid development of camera technology and artificial intelligence (AI), current cameras usually also support AI capabilities, for example, the camera can identify targets and capture the recognized targets.

Before the camera works, the user (for example, a camera installer) can first install the camera at a suitable position, so that the camera can capture a preset monitoring scene. Then, the user needs to debug the camera so that the camera can capture objects (for example, people or vehicles) in the monitoring scene with higher quality when the camera is working later. In the debugging process, the debugging target as the shooting target is usually preset in the monitoring scene, and then the user repeatedly adjusts the shooting angle and shooting parameters of the camera based on the shooting pictures of the camera and manual experience, so that the debugging target The position, size and angle of the target in the shooting picture of the camera meet the requirements.

It can be seen that in this debugging process, the efficiency is extremely low; moreover, since this process is adjusted based on manual experience, the final debugging effect cannot be guaranteed.

Contents of the invention

Embodiments of the present application provide a method for debugging a camera and related equipment, which are used to improve the debugging efficiency of the camera and improve the debugging effect of the camera. The embodiment of the present application also provides a corresponding computer-readable storage medium, a device for debugging a camera, and the like.

The first aspect of the present application provides a method for debugging a camera, including: obtaining a shooting picture obtained by shooting a monitoring scene with the camera, the shooting picture includes a debugging target, and the debugging target is set in the monitoring scene and is used for debugging the camera The shooting target; display the guide frame on the shooting screen, the guide frame is used to guide the user to adjust the shooting angle and/or shooting parameters of the camera, so that the overlap between the first area and the second area meets the user's needs, the first area is The area where the debugging target is located in the shooting screen, and the second area is the area where the guide frame is located in the shooting screen.

When the camera is being debugged, it continuously obtains the shooting images, so that the user can debug the camera based on the shooting images and the guide frame in the shooting images. The area where the above-mentioned guide frame is located can be understood as the ideal or expected area in the shooting picture captured by the camera when it is working. Therefore, the higher the coincidence degree between the first area and the second area above, the better the shooting angle and shooting parameters of the camera are. The closer to the ideal angle and parameters. Therefore, in the first aspect above, by displaying the guide frame on the shooting screen of the camera, the user can intuitively see the comparison between the debugging target and the guide frame in the shooting screen during the debugging process, thus guiding The user quickly adjusts the shooting angle and/or shooting parameters of the camera, so that the debugging target and the guide frame in the obtained shooting picture overlap as much as possible, thereby improving the debugging efficiency of the camera. Moreover, in this solution, since each user debugs the camera according to the guide frame, the standard is unified, so the problem that the debugging effect of the camera cannot be guaranteed due to the uneven manual experience of different users can be avoided.

In a possible implementation manner of the first aspect, displaying the guide frame on the shooting screen includes: acquiring a target type of the debugging target, and displaying the guide frame on the shooting screen, where the type of the guide frame is determined based on the target type.

Since the debugging target is usually set based on the actual capture requirements, for example, if you want to capture a person in the monitoring scene, the debugging target is a person (at this time, the target type is a person), if you want to If the vehicle in the monitoring scene is captured, the debugging target is a vehicle (at this time, the target type is a vehicle). Therefore, in this possible implementation, different types of guide frames can be determined based on different target types, and different types of guide frames have different shapes, thus making the outline of the guide frame more closely match the outline of the actual captured target , that is, the ideal or expected area is made more accurate, and thus the debugging effect can be further improved.

In a possible implementation manner of the first aspect, the above step of: displaying the guide frame on the shooting screen includes: obtaining the resolution of the camera; displaying the guide frame on the shooting screen, and the size of the guide frame is determined based on the resolution.

In this possible implementation, guide frames of different sizes are determined based on different resolutions, so that the size of the guide frame matches the resolution of the camera, so that the guide frame can be used for shooting pictures with different resolutions. The size of is displayed on the shooting screen, so the applicability and debugging effect of the solution can be improved.

In a possible implementation manner of the first aspect, the above step of: displaying the guide frame on the shooting screen includes: displaying the guide frame in a preset area of the shooting screen. For example, the second area may be set according to the focus area of the camera. Specifically, from the left-right (horizontal) dimension, the guide frame is located in the middle of the shooting picture, and from the up-down (vertical) dimension, the guide frame is located at the bottom of the shooting picture, for example, the focus area (second area) of the camera is In the middle of the bottom of the shooting screen, and the height is not greater than one-third of the height of the shooting screen, this area is an ideal focus area for the camera. Then, if the guide frame is set in this area, the camera can see the area where the guide frame is located. Focusing can further make the area where the guide frame is located (that is, the area where the capture target is located when the camera is working) clearer in the picture captured by the camera, and the image quality of the capture target is the best, so the capture effect can be improved.

In a possible implementation manner of the first aspect, the transparency of the second area and the third area are different, and the third area is an area in the shooting frame other than the second area.

In this possible implementation manner, the second area corresponding to the guide frame and the remaining third area in the shooting screen are displayed separately, which enhances the guidance function for the user and improves the user experience.

In a possible implementation manner of the first aspect, the above step of: displaying the guide frame on the shooting screen includes: displaying an outline of the second region on the shooting screen.

In this possible implementation manner, it is equivalent to displaying the guide frame by displaying the outline of the second area when the second area is displayed on the shooting screen, which enhances the guiding function for the user and improves the user experience.

In a possible implementation manner of the first aspect, the method further includes: determining the focus area and/or encoding parameters of the camera, so that the definition of the second area is higher than the definition of the third area, and the third area is Capture the area of the frame other than the second area.

It should be understood that after the debugging is completed, the second area where the guide frame is located is the area where the captured target is located. Therefore, in this possible implementation mode, in the shooting picture obtained by the camera during operation, the clarity of the area where the captured target is located The sharpness is higher than that of other areas, which can improve the effect of capture.

In a possible implementation manner of the first aspect, the above step: after displaying the guide frame on the shooting screen, the method further includes: detecting a degree of overlap between the first area and the second area; and outputting the degree of overlap.

Since the degree of overlap quantifies the overlap or matching of the first area and the second area, it can reflect the overlap of the two areas more accurately. Therefore, in this possible implementation, the user can conveniently know the The precise coincidence of the two regions allows the user to debug according to the change of the coincidence, thus further improving the efficiency of debugging and improving the user experience.

Optionally, the coincidence degree can be played and output in the form of voice, or displayed in the form of text, and the user can intuitively feel the current coincidence degree in the process of debugging the camera, which is convenient for the user to debug and improves the user experience.

In a possible implementation manner of the first aspect, the above step: after detecting the degree of overlap between the first area and the second area, the method further includes: when the degree of overlap is not higher than the first threshold, outputting the first Prompt information, the first prompt information is used to prompt the user to adjust the shooting angle and/or shooting parameters of the camera.

In this possible implementation manner, improving the guiding function for the user to debug the camera can improve the user's experience.

Optionally, the first prompt information can be played and output in the form of voice, or displayed and output in the form of text, and the user can intuitively feel the first prompt information during the process of debugging the camera, which is convenient for the user to debug and improves the user experience.

In a possible implementation of the first aspect, when the coincidence degree is less than the second threshold, the first prompt information is used to prompt the user to adjust the shooting angle of the camera; In the case of a threshold value, the first prompt is used to prompt the user to adjust the shooting parameters of the camera.

In this possible implementation, different prompt information is sent to the user according to different overlapping degrees, which further improves the guiding function for the user to debug the camera, thereby further improving the debugging efficiency and the user debugging experience.

In a possible implementation of the first aspect, the above step: after detecting the degree of overlap between the first area and the second area, the method further includes: outputting a second prompt when the degree of overlap is higher than the first threshold information, and the second prompt information is used to indicate that the debugging of the camera has been completed.

In this possible implementation manner, the guiding function for the user to debug the camera can also be improved, and the user experience can be improved.

Optionally, the first prompt information can be played and output in the form of voice, or displayed and output in the form of text, and the user can intuitively feel the second prompt information in the process of debugging the camera, which is convenient for the user to debug and improves the user experience.

In a possible implementation manner of the first aspect, the above step of: displaying the guide frame on the shooting screen includes: displaying the guide frame on the shooting screen in response to a first instruction, the first instruction being used to indicate entering the debugging mode.

In this possible implementation manner, after the user issues the first instruction for instructing to enter the debugging mode, a guide frame is displayed on the shooting screen, which improves the feasibility of the solution.

In a possible implementation manner of the first aspect, the above steps: after displaying the guide frame on the shooting screen in response to the first instruction, the method further includes: in response to the second instruction, stop displaying the guide frame on the shooting screen, The second command is used to indicate to exit the debug mode.

In this possible implementation manner, after the user issues the second instruction for instructing to exit the debugging mode, the display of the guide frame on the shooting screen is stopped, which improves the feasibility of the solution.

In a possible implementation manner of the first aspect, the position or angle of the first area is related to a shooting angle, and the size of the first area is related to a shooting parameter.

In addition, in order to better illustrate the present application, numerous specific details are given in the following specific implementation manners. It will be understood by those skilled in the art that the present application may be practiced without certain of the specific details. In some instances, methods, means, components and circuits well known to those skilled in the art have not been described in detail in order to highlight the gist of the present application.

Embodiments of the present application provide a method for debugging a camera and related equipment, which are used to improve the debugging efficiency of the camera and improve the debugging effect of the camera. The embodiment of the present application also provides a corresponding computer-readable storage medium, a device for debugging a camera, and the like. Each will be described in detail below.

The application scenarios of the embodiments of the present application are illustrated below with examples.

With the rapid development of camera technology, the application of cameras is becoming more and more extensive, and cameras supporting artificial intelligence (AI) capabilities can realize intelligent target capture. Specifically, when the camera is working, it continuously shoots the monitoring scene (that is, continuously records or continuously shoots), and the shooting result obtained by the camera is a video that contains continuous multi-frame shooting pictures. The user (for example, the installer of the camera, or The user) can set the capture range on the shooting screen in advance; when the camera captures the shooting screen and performs capture target detection on the shooting screen, when the camera detects the capture target in a certain shooting screen and detects that the capture target is located at When shooting the preset capture range in the picture, the capture target can be automatically captured to obtain an image including the capture target, that is, a capture frame or a capture image.

In order to obtain better capture results, it is usually necessary to debug the camera. During the debugging process, the camera is usually allowed to shoot continuously to obtain the shooting picture, and by setting the debugging target, and then adjusting the shooting angle and shooting parameters of the camera, the debugging target is located in the ideal area of the camera shooting picture.

Before debugging the camera, the user (for example, a camera debugging worker) may first specify the capture target and the capture area in the monitoring scene.

Exemplarily, as shown in FIG. 1 , assuming that the monitoring scene of camera C is the entrance of a certain building, specifically, camera C needs to capture the crowd entering a certain building, then the user can determine that the capturing target in the monitoring scene is a person . Moreover, after analysis, the user finds that people pass through area A with a high probability when entering the building, so the user can use area A as the capture area in this scene.

Exemplarily, as shown in FIG. 2 , assuming that the monitoring scene of the camera C is a certain parking lot, and a vehicle entering the parking lot needs to be captured, the user can determine that the target of the capturing in the monitoring scene is a vehicle. After analysis, the user finds that when the vehicle enters the parking lot, it usually stops in front of the barrier, and the license plate of the vehicle is likely to be in area B. Then, the user can use area B as the capture area in this scene.

After specifying the capture target and capture area in the monitoring scene, the user can set a debugging target consistent with the capture target in the capture area of the monitoring scene. For example, in the scenario shown in FIG. 1 , the user may allow a certain person to be a debugging target, and allow the person who is the debugging target to be in area A. In the scenario shown in FIG. 2 , the user may use a certain vehicle as a debugging target, and let the license plate of the vehicle used as the debugging target be located in area B. During the debugging process, the debugging target can always be located at the above-mentioned pre-defined capture area, so as to assist the user to complete the camera debugging.

It should be understood that the situation of the debugging target in the shooting picture reflects the situation of the captured target in the shooting picture when the camera is working subsequently. Therefore, by adjusting the shooting angle and shooting parameters of the camera, so that the angle, size and position of the debugging target are in an ideal state, the camera can capture the angle, size and position of the target in most cases during follow-up work. It is in an ideal state, so that the quality of the captured target is guaranteed.

The present application provides a method for debugging a camera, and the method for debugging a camera may be executed by a device for debugging a camera (referred to as a debugging device). It should be understood that the debugging device may be the camera to be debugged itself, or any other device with computing and display functions, for example, it may be a computer, mobile phone or tablet computer, etc., which is not limited in this embodiment of the present application.

This application uses the application scenario shown in FIG. 1 as an example to introduce the method for debugging the camera.

An implementation manner of the method for debugging a camera provided by the present application will be described below with reference to FIGS. 3-6B .

As shown in Figure 3, the method for debugging the camera includes but is not limited to the following steps:

S301. Obtain a shooting picture obtained by shooting a monitoring scene by a camera.

During the debugging process, the debugging device can continuously and in real time acquire the shooting pictures obtained by the camera shooting the monitoring scene, so that the user can complete the debugging of the camera according to the shooting pictures. Since during the debugging process, a debugging target is set at a preset position of the monitoring scene (that is, a position in the pre-determined capture area), therefore, the shooting screen includes the debugging target. For example, in the scene shown in FIG. 1 , a person located in area A is included in the shooting picture.

It should be understood that when the debugging device is other equipment different from the camera, the debugging device can communicate with the camera and receive the shooting pictures sent by the camera; screen.

S302. Display the guide frame on the shooting screen.

Wherein, the guide frame is used to guide the user to adjust the shooting angle and/or shooting parameters of the camera, so that the coincidence degree of the first area and the second area meets the needs of the user; wherein, the first area is where the debugging target in the shooting picture is located. area, and the second area is the area where the guide frame is located in the shooting screen.

The following describes the shape, size and position of the guide frame displayed on the shooting screen.

Exemplarily, the shape of the guide frame displayed on the shooting screen may be determined according to the capture requirements. Specifically, multiple types of guide frames may be set according to capturing requirements, and each type of guide frame has a different shape. Then, the type of the guide frame can be determined according to the type of the debugging target, and the guide frame of this type can be displayed. For example, guide frames of the "person" type and "vehicle" type can be set in advance, wherein the shape (contour) of the "person" type guide frame can be the whole body or the upper body of a person, and the shape (contour) of the "vehicle" type guide frame can be for the vehicle. In this embodiment, the type of the debugging target is "person", so a guide frame of the type "person" can be displayed.

It should be understood that according to the actual capture requirements, the debugging target can also include other types besides the above-mentioned "person" and "vehicle". Correspondingly, more types of guide frames can be set, that is, more shapes of guide frames can be set , which is not limited in this application.

In addition, optionally, the shape of the guide frame displayed on the shooting screen may also be a preset fixed shape, which is not limited in this application.

Exemplarily, the size of the guide frame displayed on the shooting screen may be determined according to the resolution of the camera. That is to say, the size of the guide frame can be adjusted according to the resolution of the camera, so that the size of the guide frame in the shooting pictures of different cameras can be all appropriate. It should be understood that when the resolution of the camera is higher, the size of the guide frame should be larger, and when the resolution of the camera is lower, the size of the guide frame should be smaller. In actual implementation, the corresponding relationship between different resolutions and different guide frame sizes (dimensions) can be preset, and guide frames of corresponding sizes can be displayed on the shooting screen according to the resolution of the camera to be debugged.

Optionally, the size of the guide frame displayed on the shooting screen can also be set according to the pixel requirements of the capture target, that is, the size of the guide frame can be adjusted according to the pixel requirements of different capture targets in the actual scene, which can make Under different capture targets, the guide frame can meet its pixel requirements.

Optionally, the size of the guide frame displayed on the shooting screen may also be a preset fixed size, which is not limited in this application.

Exemplarily, the displayed position of the guide frame on the shooting screen may be a preset position according to actual needs, for example, the displayed position of the guide frame may be set according to the focus area of the camera. Specifically, from the left-right (horizontal) dimension, the guide frame is located in the middle of the shooting picture, and from the up-down (vertical) dimension, the guide frame is located at the bottom of the shooting picture, for example, the focus area (second area) of the camera is The bottom of the shooting screen is in the middle, and the height is not greater than one-third of the height of the shooting screen. More specifically, the longitudinal centerline of the shooting screen and the longitudinal centerline of the second area are coincident, and the bottom of the shooting screen and the second area The bottoms of the two areas overlap, and the vertical height of the second area is not greater than one-third of the vertical height of the shooting screen, that is, the shooting screen is divided into three horizontally, and the second area is located in the area closest to the bottom Middle, the middle position in the horizontal direction. This area is the most ideal focus area of the camera. Then, the position of the guide frame can be set in this area, so that the camera can focus on the area where the guide frame is located, and then the area where the guide frame is located can be made in the picture captured by the camera. (that is, the area where the captured target is located when the camera is working) is clearer, and the image quality of the captured target is the best, thus the effect of capturing can be improved. For example, 20 shown in FIG. 4 . It should be understood that since the guide frame corresponds to an area, the display position of the guide frame on the shooting screen can be measured by the position of a certain point of the guide frame on the shooting screen, for example, the position on the outline of the guide frame can be measured A certain point, or the center point of the guide frame (the intersection of the horizontal midline and the vertical midline), which is not limited in this application.

It should be understood that the location of the above second area is generally an ideal focus area of the camera in the entire shooting picture, and setting the guide frame in this area can make the quality of the captured object in the shooting picture higher, thereby improving the effect of capturing. It should be noted that, depending on the actual situation, the preferred area where the camera focuses will also change. Correspondingly, the specific position of the second area in the shooting picture can be adjusted according to the actual situation, which is not limited in this embodiment of the present application. Of course, in some implementation manners, the displayed position of the guide frame on the shooting screen may be other positions preset according to actual needs, regardless of the focus area of the camera, which is not limited in this application. In combination with the above solution, in a practical example, the debugging device can display an interface for the user to input the type of the debugging target, the resolution of the camera, or the position of the required guide frame, so that the position of the guide frame can be determined based on the user's input. shape, size or position, so that a guide frame of corresponding shape and size is displayed at the corresponding position of the shooting screen.

The present application does not limit the display form of the guide frame on the shooting screen, as long as the user can intuitively recognize the guide frame in the shooting screen. Several possible display forms of the guide frame on the shooting screen are introduced below.

Manner 1: The guide frame may be displayed in the form of a contour line, specifically, the contour line of the guide frame may be displayed on the shooting screen, for example, the second area 20 in FIG. 4 . Wherein, the contour lines may be dotted lines or solid lines of different thicknesses, types, and colors, etc., which are not limited in this embodiment of the present application.

Manner 2: The guiding frame may be displayed by setting different transparencies in the second area (ie, the area where the guiding frame is located) and the third area. Wherein, the third area is an area in the shooting frame other than the second area. As shown in FIG. 5 , when the debugging device displays the guide frame, the transparency of the second area 20 and the third area 30 may be set to be different. It should be understood that the present application does not limit the specific transparency values of the second area and the third area, as long as the user can distinguish the second area and the third area through different transparency. When the second area is not completely transparent, it can also be filled, for example, it can be filled with a solid color, filled with a gradient, or filled with a pattern. The third area may also be treated similarly, which is not limited in this embodiment of the present application. For example, in FIG. 5 , the debugging device fills the third area with oblique lines.

Optionally, in the second method, the guide frame is displayed on the shooting screen by superimposing a transparent picture with an alpha channel (alpha channel), so as to realize different transparency of the second area and the third area, wherein the alpha channel can be Used to adjust the translucency of an image, the camera debugging system superimposes a transparent image with an alpha channel on the shooting screen as a guide frame.

Optionally, the above method 1 and method 2 can also be used in combination, that is, while displaying the guide frame in the form of outlines, the second area and the third area can also be set with different transparency, so as to further enhance the guiding effect on the user .

It should be understood that, in the process of debugging, the shape, size and position of the guide frame (that is, the second area) displayed on the shooting screen of the camera generally remain unchanged (that is, the content in the shooting screen can change, but the display on the shooting screen The bootstrap frame remains the same). Therefore, the overlapping of the above-mentioned first area (that is, the area where the debugging target is located in the shooting picture) and the second area is determined by the shape, size and position of the first area. Wherein, the shape and position of the first area are related to the shooting angle of the camera, and the size of the first area is related to the shooting parameters of the camera. Specifically, adjusting the shooting angle of the camera is equivalent to controlling the camera to rotate, and the range of the camera shooting the monitoring scene can be adjusted. At this time, the shape and position of the area (ie, the first area) of the debugging target in the shooting picture can be adjusted. Adjusting the shooting parameters of the camera is equivalent to controlling parameters such as the optical magnification of the camera lens, and can adjust the distance of the camera shooting the monitoring scene. At this time, the size of the area (ie, the first area) of the debugging target in the shooting picture can be adjusted. Therefore, the user can continuously adjust the shooting angle and/or shooting parameters of the camera to increase the degree of overlap between the first area and the second area until the degree of overlap reaches the user's satisfaction. For example, the user can complete the debugging when he sees that the first area and the second area almost completely overlap. Exemplarily, as shown in FIG. 6A , assuming that the debugging device displays a guide frame on the shooting screen after acquiring the shooting screen, the user finds that the first area 10 where the debugging target is located and the second area 20 where the guide frame is located do not overlap. . Then, after the user adjusts the shooting angle and/or shooting parameters of the camera, as shown in FIG. 6B , the first area 10 and the second area 20 are almost completely overlapped. The degree of coincidence meets the requirements, so the camera shooting angle and/or shooting parameters can be adjusted to complete the debugging of the camera.

In addition, the advantages of the above-mentioned solution of the present application are more obvious in the scene where there is a requirement for the pixels of the captured object in the shooting picture of the camera. For example, in the scene of face capture, it is usually required that the pixels between the two ears of the face in the captured picture be 120px; Under such circumstances, in the existing debugging scheme, the user cannot directly judge whether the pixel value of the capture target in the shooting screen meets the requirements with the naked eye, so the user needs to manually adjust the optical magnification of the camera repeatedly to meet the capture requirements. And if the above-mentioned solution of the present application is adopted, by displaying the guide frame on the shooting screen, and setting the size of the guide frame to meet the capture requirements (for example, the width in the horizontal direction is not less than 120px), then the user only needs to adjust the camera to make the shooting The debugging target in the screen basically coincides with the guide frame, so that the pixel value of the capture target in the shooting screen of the camera can meet the requirements.

Since the camera usually focuses based on a preset focusing algorithm, the focusing algorithm usually takes the central area of the shooting picture as a high-weight area for focusing, and the result of this is to make the picture quality of the central area of the shooting picture better. However, in actual situations, the second area where the guide frame is located may not be in the central area of the screen. Also, in some other cases, the camera may focus on the background or other areas that the user does not care about. For example, in a low-light environment, in order to obtain better shooting results, the camera usually shoots with a large aperture and a shallow depth of field. This shooting method may cause the camera to focus on the background of the shooting picture and other things that the user does not care about. in the area. In view of the above two situations, optionally, in the embodiment provided by this application, the debugging device can also adjust the focus area of the camera, so that the camera uses the second area as the focus area, so that the definition of the second area is higher than that of the first area. Three-zone clarity. It should be understood that after the debugging is completed, the second area where the guide frame is located is the area where the capture target is located. Therefore, in this way, the resolution of the area where the capture target is located in the shooting picture obtained by the camera during operation can be higher. , so that the capture effect can be improved, and the accuracy of subsequent intelligent analysis of the capture target can be improved.

Optionally, the user can manually confirm the focus area. After the user thinks that the coincidence degree of the first area and the coincidence degree of the second area meet the requirements, the user triggers the camera to focus, or the debugging device automatically triggers the camera to focus. This application implements For example, this is not limited. The default focus area of the camera is the second area. After the user confirms that the definition of the debugging target meets the user's needs after the camera is focused, the user can confirm that the focus area of the camera is the current focus area through the debugging device. After confirming the focus area, the camera will use the focus area confirmed by the user as the focus area to shoot or capture during the subsequent working process of the camera. If the definition of the debugging target does not meet the user's needs after the camera is focused, the user can also use the debugging The device manually adjusts the current focus area and then confirms the focus area of the camera.

It should be noted that, in the above implementation process, when the debugging device is other equipment than the camera, the debugging device can also send the determined focus area to the camera, so that the camera can capture pictures according to the focus area during operation, thus obtaining Make the capture target clear and capture the picture.

Optionally, after the focus area is determined, the user can determine the capture range of the camera in the shooting screen through the debugging device. The default capture range of the camera is the entire shooting screen, but there are cases where the camera also captures when the capture target is not in the focus area. , the quality of the capture result will be relatively poor, so the user can draw or adjust the capture range of the camera in the shooting screen through the debugging device, for example, the user sets the capture range to the bottom third of the shooting screen, and for example The capture range set by the user is the second area. When the capture target is within the capture range in the shooting screen, the camera will start capturing, so that the quality of the capture result can be significantly improved.

In addition, when the camera is working, it may need to compress the captured pictures and send them to other devices. For example, the camera may encode the captured pictures in JPEG (joint photographic experts group) mode, or use standard encoding such as H.264 and send them to stored on the server. Therefore, also optionally, the debugging device can also determine the encoding parameters of the camera, so that the camera can use the area where the guide frame is located (that is, the second area) as the encoding parameter when encoding the shooting picture during subsequent work. A region of interest (region of interest, ROI), so that in the encoded corresponding image, the definition of the second region is higher than the definition of other regions. In this implementation mode, the above encoding parameters may be the indication information of the encoded ROI area; and, when the debugging device is a device other than the camera, the debugging device may also send the encoding parameters to the camera, so that the camera is Encode according to this encoding parameter during work. It should be understood that, in this way, the definition of the area where the captured target is located can also be made higher, thus the effect of capturing can be improved, and the accuracy of subsequent intelligent analysis of the captured target can be improved.

Another implementation of the method for debugging a camera provided by the present application will be introduced below with reference to FIGS. 7-8 .

As shown in Figure 7, the method for debugging the camera includes but is not limited to the following steps:

S701. Acquire a shooting picture obtained by shooting a monitoring scene by a camera.

Please refer to the relevant description in S301 above, and details will not be repeated here.

S702. Display a guide frame on the shooting screen in response to the first instruction.

As shown in FIG. 8 , after the shooting screen is acquired, the guide frame may be displayed on the shooting screen after the user triggers the debugging mode. Exemplarily, the debugging device includes a display screen, and a debugging interface and a shooting frame can be displayed on the display screen, wherein the shooting frame frame is set on the left side of the display screen, and the debugging interface is set on the right side of the display screen. After the screen is displayed, the shooting screen is displayed in the shooting screen frame. When the user clicks the button to start debugging in the debugging interface, it is equivalent to sending the first instruction by the user. The debugging device may respond to the user's first instruction indicating to enter the debugging mode, and start displaying the guide frame on the shooting screen. For the manner of displaying the guide frame on the shooting screen, reference may be made to the introduction of S302 above, and details will not be repeated here.

It should be noted that there are many ways and forms for the display screen to display the debugging interface and the shooting picture. After the debugging button (virtual button) is pressed, the shooting picture will start to be displayed in the shooting picture frame, and the guide frame will be displayed at the same time. The return button on the display screen exits to re-display the adjustment interface, which is not limited in this embodiment of the present application.

S703. Detect the overlapping degree of the first area and the second area, and output the overlapping degree.

After the guide frame is displayed on the shooting screen, the user can adjust the shooting angle and/or shooting parameters of the camera. Specifically, the user can adjust the shooting angle and shooting parameters of the camera, for example, move the camera to adjust the shooting angle, control the adjustment buttons of the camera to adjust the shooting parameters, and in order to make debugging more convenient for the user, the user can also input the The shooting angle and shooting parameters need to be adjusted, and the debugging device transmits these data to the camera, and the camera automatically adjusts the shooting angle and shooting parameters according to these data. During this process, the debugging device can monitor the coincidence degree of the first area and the second area in real time, and output the coincidence degree.

Specifically, the debugging device can identify the first area. Then, for example, according to the area proportion of the first area in the second area and the area proportion of the second area in the first area, the degree of overlap between the first area and the second area can be determined, and based on this, real-time Output coincidence. Since the degree of overlap quantifies the overlap or matching of the first area and the second area, it can reflect the overlap of the two areas more accurately. Therefore, in this possible implementation, the user can conveniently know the The precise coincidence of the two regions allows the user to debug according to the change of the coincidence, thus further improving the efficiency of debugging and improving the user experience.

It should be noted that the coincidence degree between the first region and the second region may also be calculated in other ways, which is not limited in the present application.

Optionally, the debugging device is also equipped with a sound, and the coincidence degree can be played and output in the form of voice, or displayed in the form of text, or output in both forms at the same time, so that the user can intuitively feel it in the process of debugging the camera. To the current coincidence degree, it is convenient for users to debug and improves user experience.

Among them, when the coincidence degree is output in the form of text, the coincidence degree can be displayed on the shooting screen or on an interface outside the shooting screen, for example, displayed above the second area on the shooting screen, or displayed in the debugging interface , the coincidence degree can be displayed by text in various fonts, colors, or sizes, or the percentage represented by the coincidence degree can be displayed through a bar graph, which is not limited in this embodiment of the present application.

S704. In a case where the overlap degree is not higher than the first threshold, output first prompt information.

When the coincidence degree is not higher than the first threshold, it means that the gap between the debugging target and the guide frame is still relatively obvious, and the user needs to adjust the shooting angle and/or shooting parameters of the camera. At this time, the first prompt message is output to prompt the user to adjust the shooting angle of the camera. The shooting angle and/or shooting parameters improve the guiding function for the user to debug the camera and improve the user experience.

Optionally, when the coincidence degree is less than the first threshold, the debugging device can also provide more detailed and targeted prompts to the user. Specifically, a second threshold can be set (the second threshold is less than the first threshold), and when the degree of overlap is less than the second threshold, the first prompt information can be information for prompting the user to adjust the shooting angle of the camera; and In a case where the coincidence degree is greater than the second threshold and less than the first threshold, the first prompt may be information for prompting the user to adjust shooting parameters of the camera. Wherein, the above-mentioned first threshold and second threshold may be preset values, which are not limited in this application.

For example, assuming that the first threshold is 90% and the second threshold is 70%, then when the user starts to debug the camera, the debugging target may be far away from the guide frame, so the debugging device detects the first area and the second area The coincidence degree is less than 70%. At this time, the debugging device may output first prompt information prompting the user to adjust the shooting angle of the camera. For example, in the debugging interface, it displays "Please adjust the shooting angle of the camera so that the position of the debugging target is close to the guide frame", and at the same time play the video "Please adjust the shooting angle of the camera so that the position of the debugging target is close to the guiding frame". voice.

Then, when the user adjusts the shooting angle of the camera so that the debugging device detects that the coincidence degree between the first area and the second area is greater than or equal to 70% but less than or equal to 90%, it means that the debugging target and the guide frame are shooting The position and shape in the screen may be relatively close, but the size of the debugging target may be different from the guide frame. In this case, the debugging device may output first prompt information prompting the user to adjust the shooting parameters of the camera. For example, "Please adjust the shooting parameters of the camera so that the debugging target coincides with the guiding frame" is displayed in the debugging interface, and at the same time the voice of "Please adjust the shooting parameters of the camera so that the debugging target coincides with the guiding frame" is played. At this point, after seeing the prompt, the user can adjust the optical magnification of the camera lens so that the size of the debugging target better matches the size of the guide frame. It should be understood that, further, when the debugging device detects that the coincidence degree of the first area and the second area is higher than 90%, step S706 is executed.

S705. In the case that the degree of coincidence is higher than the first threshold, output second prompt information.

Optionally, the second prompt information can be played and output in the form of voice, or displayed and output in text form, and the user can intuitively feel the second prompt information in the process of debugging the camera, which is convenient for the user to debug and improves the user experience.

When the coincidence degree is higher than the first threshold, it usually indicates that the coincidence of the debugging target and the guide frame meets the expected requirements. Therefore, at this time, the debugging device can output a second prompt message, for example, display "commissioning completed" in the debugging interface , and at the same time play the voice of "debugging completed", the second prompt information indicates that the debugging of the camera has been completed, which improves the guiding function for the user to debug the camera and improves the user experience.

S706. Stop displaying the guide frame on the shooting screen in response to the second instruction.

When the debugging device outputs the second prompt information, the user can observe the relationship between the debugging target and the guide frame in the shooting screen at this time. It is determined to stop debugging in the debugging device. For example, after the debugging device outputs the second prompt message, the user clicks the button to stop debugging in the debugging interface. The second command is to stop displaying the guide frame on the shooting screen and complete the debugging of the camera. When the debugging device outputs the second prompt information, the user can also continue debugging according to the observed situation until the user's requirement is met, and details will not be repeated here.

It should be noted that the user can click the button to stop debugging under any circumstances to make the debugging device exit the debugging module. At this time, the debugging device will control the camera to save the current shooting parameters and shooting angles, so that when the user returns to the debugging mode later, he can Continue the last debugging work.

In the embodiment of the present application, the debugging device detects the degree of coincidence between the first region corresponding to the debugging target and the second region corresponding to the guide frame, and can output the degree of coincidence in various ways; The coincidence degree outputs different prompt information. Therefore, compared with the embodiment shown in FIG. 3 , this embodiment can further enhance the guiding function for user debugging, thereby further improving the efficiency of user debugging of cameras and improving user experience.

It should be understood that, similar to the implementation shown in FIG. 3 , in the implementation shown in FIG. 7 , the debugging device may also determine the focus area and/or encoding parameters of the camera, so that in the picture captured by the camera and the encoded picture, The area where the guide frame is located is clearer, which can improve the quality of the capture, so I won’t repeat it here.

Also similar to the implementation manner shown in FIG. 3 , the implementation manner shown in FIG. 7 can also be applied to a scene where there are multiple capture objects, so details will not be repeated here.
