101. Acquire a first 3D model of a target scene and a first position of a first camera, where the first camera is a camera in the target scene, and the first position is a position in a coordinate system of the first 3D model.

For example, the target scene is inside a building; for another example, the target scene is an underground parking lot; for another example, the target scene is a campus; for another example, the target scene is a scene in a shopping mall.

In the embodiment of the present application, the three-dimensional model (including the first three-dimensional model and the second three-dimensional model to be mentioned below) may be a computer-aided design (computer aided design, CAD) three-dimensional model, and the three-dimensional model may also be a three-dimensional convex hull, A 3D model can also be a 3D point cloud.

In an implementation manner of acquiring the first 3D model of the target scene, the image processing device uses the 3D model of the target scene input by the user through the input component as the first 3D model. The above-mentioned input components include: a keyboard, a mouse, a touch screen, a touch pad and an audio input device.

In another implementation manner of acquiring the first 3D model of the target scene, the image processing apparatus receives the 3D model of the target scene sent by the terminal as the first 3D model.

In yet another implementation manner of acquiring the first three-dimensional model of the target scene, the image processing device includes a laser radar. The image processing device scans the target scene through the laser radar, and obtains a 3D model of the target scene as a first 3D model.

In an implementation manner of acquiring the first position of the first camera, the image processing apparatus uses the position of the first camera input by the user through the input component as the first position.

In another implementation manner of acquiring the first position of the first camera, the image processing apparatus receives the position of the first camera sent by the terminal as the first position.

In yet another implementation of acquiring the first position of the first camera, the image processing device acquires the second position of the first camera in the global positioning system and the coordinate transformation relationship, wherein the coordinate transformation relationship is the coordinate system of the global positioning system The conversion relationship with the coordinate system of the first 3D model. The image processing device converts the second position according to the coordinate transformation relationship to obtain the first position of the first camera.

It should be understood that, in this embodiment of the present application, acquiring the first three-dimensional model of the target scene and acquiring the first position of the first camera may be performed separately, or may be performed simultaneously.

102. Display the first camera in the first three-dimensional model according to the first position.

In the embodiment of the present application, the image processing device displays the first camera in the first three-dimensional model according to the first position, so as to more intuitively display the position of the first camera in the target scene.

It should be understood that the first camera in this embodiment of the present application is only an example, and in practical applications, the image processing apparatus may display any camera in the target scene in the first three-dimensional model.

As an optional implementation manner, the image processing device also performs the following steps:

1. Obtain the camera parameters of the above-mentioned first camera.

In this step, the camera parameters include one or more of the following: orientation, camera type, and viewing angle. The orientation may be the orientation of the camera in the coordinate system of the first three-dimensional model, or the coordinates of the camera in the coordinate system of the global positioning system. Camera types include dome cameras, bolt cameras, and dome cameras. The viewing angle may be the shooting range of the camera in the coordinate system of the first three-dimensional model, and the shooting range may also be the coordinates of the camera in the global positioning system coordinate system.

In an implementation manner of acquiring the camera parameters of the first camera, the image processing device uses the camera parameters input by the user through the input component as the camera parameters of the first camera.

In another implementation manner of acquiring the camera parameters of the first camera, the image processing apparatus receives the camera parameters sent by the terminal as the camera parameters of the first camera.

2. Visually display the camera parameters in the first three-dimensional model.

In this step, visualization refers to converting data into graphics or images for display on the screen. The image processing device displays the camera parameters in the first three-dimensional model in a visualized manner, which can make the display effect of the first camera more intuitive.

For example, the effect shown in FIG. 2 can be obtained by displaying camera parameters in a scalable manner, wherein the fan-shaped area captured by the first camera is the shooting range of the camera. It can be known from FIG. 2 that the first camera is a dome camera, that is, the first camera is a dome camera. The orientation of the first camera can also be intuitively felt through FIG. 2 .

The image processing device can improve the display effect of the camera parameters of the first camera by performing step 1 and step 2

As an optional implementation manner, the image processing device also performs the following steps:

3. When an instruction to preview the picture captured by the above-mentioned first camera is detected, display the picture captured by the above-mentioned first camera in the display area of the above-mentioned first camera, and the display area of the above-mentioned first camera belongs to the above-mentioned first camera. A display area covered by a 3D model.

In this step, previewing the picture captured by the first camera may be displaying the image or video stream captured by the first camera.

The instruction to preview the picture captured by the first camera may be an instruction input by the user to the image processing device through the input component. For example, when the image processing device displays the first three-dimensional model on the touch screen, when the user touches the first camera in the first three-dimensional model, the image processing device generates an instruction to preview the picture captured by the first camera . For another example, when the image processing device displays the first 3D model on the screen, and the user clicks the first camera in the first 3D model with a mouse cursor, the image processing device generates an instruction to preview the image captured by the first camera.

The instruction to preview the image captured by the first camera may also be an instruction generated when a condition for previewing the image captured by the first camera is met.

For example, the condition for previewing the picture captured by the first camera is that the target object appears within the shooting range of the first camera. When the image processing device determines that the image captured by the first camera contains the target object by comparing the image captured by the first camera with the image containing the target object, it determines that the target object appears within the shooting range of the first camera, that is, determines Meet the conditions for previewing the images captured by the first camera.

For example, image processing determines that Zhang San appears in the shooting range of the first camera when the image captured by the first camera is compared with Zhang San's face image to determine that the image captured by the first camera contains Zhang San Then, it is determined that the conditions for previewing the picture captured by the first camera are satisfied.

For another example, the condition for previewing the picture captured by the first camera is that the duration of the target object appearing in the shooting range of the first camera exceeds a duration threshold. When the image processing device compares the image captured by the first camera with the image containing the target object and determines that the duration of the target object appearing in the shooting range of the first camera exceeds the duration threshold, it determines that the first camera meets the preview requirement. The condition of the captured picture.

In this step, the display area of the first camera is used to display the picture captured by the first camera, and the display area of the first camera is located in the display area of the first three-dimensional model.

In a possible implementation manner, in the display area of the first three-dimensional model, the display area of the first camera points to the first camera, indicating that the picture displayed in the display area of the first camera is captured by the first camera screen.

In another possible implementation manner, the display area of the first camera is a head up display (head up display, HUD) layer where the first camera is located.

Since the display area of the first camera is used to display the pictures captured by the first camera, the image processing device can display the pictures captured by the first camera in the display area of the first camera to make the pictures captured by the first camera The display of the picture is more intuitive, so that the user can feel more intuitively that the picture displayed in the display area of the first camera is the picture collected by the first camera. If the display area of the first camera is located in the area covered by the first three-dimensional model, the display effect of the picture captured by the first camera can be further improved.

As an optional implementation manner, the first three-dimensional model includes a first point and a second point, and a position of the first point in the first three-dimensional model is different from a position of the second point in the first three-dimensional model. In this embodiment, the image processing device also performs the following steps:

4. Determine the first number of second cameras and the second number of third cameras, the second camera is a camera whose shooting range includes the first point, and the third camera is a camera whose shooting range includes the second point.

5. The first camera coverage index is obtained according to the first quantity, and the first camera coverage index is positively correlated with the first quantity.

6. The first camera coverage index is obtained according to the above-mentioned first quantity, and the above-mentioned second camera coverage index is positively correlated with the above-mentioned second quantity.

In the embodiment of the present application, the camera coverage index of a certain point is used to represent the number of cameras whose shooting range covers the point. Suppose the first number is n ₁ , the second number is n ₂ , the coverage index of the first camera is i ₁ , and the coverage index of the second camera is i ₂ .

In a possible implementation manner, n ₁ , n ₂ , i ₁ , and i ₂ satisfy the following formula:

Wherein, k ₁ and k ₂ are positive numbers, and c ₁ and c ₂ are real numbers.

In another possible implementation manner, n ₁ , n ₂ , i ₁ , and i ₂ satisfy the following formula:

Wherein, k ₁ and k ₂ are positive numbers, and c ₁ and c ₂ are real numbers.

In yet another possible implementation manner, n ₁ , n ₂ , i ₁ , and i ₂ satisfy the following formula:

Wherein, k ₁ and k ₂ are positive numbers, and c ₁ and c ₂ are real numbers.

Since different cameras capture different images, different cameras obtain different information. Therefore, the greater the number of cameras whose shooting range includes a certain point, the higher the accuracy of the information obtained by the cameras at the point, and thus the higher the accuracy of the processing result obtained based on the information obtained by the cameras.

For example, the shooting range of camera a and the shooting range of camera b both include point A, that is, the number of cameras whose shooting range includes point A is 2. The shooting range of camera c includes point B, that is, the number of cameras whose shooting range includes point B is 1. Since the number of cameras whose shooting range includes point A is greater than the number of cameras whose shooting range includes point B, the information of point A obtained through the camera (including camera a and camera b) is greater than the information of point B obtained through the camera (ie, camera c). Point information is accurate.

If person C appears at point A, camera a captures image d containing person C. When person C appears at point A, camera b captures image e containing person C. When person D appears at point B, camera c captures image f containing person D.

The attribute information of person C determined based on image d and image e (including clothing attributes and appearance attributes) is more accurate than the attribute information of person C determined based on image f.

7. Display the above-mentioned first camera coverage indicator at the above-mentioned first point, and display the above-mentioned second camera coverage indicator at the above-mentioned second point.

In this step, the image processing device can intuitively display the accuracy of the information of the first point acquired through the camera by displaying the coverage index of the first camera at the first point. Similarly, by displaying the coverage index of the second camera at the second point, the image processing device can visually display the accuracy of the information of the second point acquired through the camera.

When the first point and the second point belong to different floors, the image processing device may display the camera coverage indicators of different floors based on steps 4 to 7 to improve the display effect of the camera coverage indicators.

Wherein, the display effect of the image processing device displaying different floors in the first three-dimensional model can be referred to FIG. 3 and FIG. 4 . The building shown in Figure 3 is the same as the building shown in Figure 4, and the target scene is the interior of the building. The floor shown in Figure 3 is the A floor of the target scene, and the floor shown in Figure 4 is the B floor of the target scene, that is, the display effect of the image processing device displaying the A floor in the first three-dimensional model can be referred to in Figure 3, the image processing device Refer to FIG. 4 for the display effect of displaying the B floor in the first three-dimensional model.

In a possible implementation manner, the first point belongs to the first floor, and the second point belongs to the second floor, wherein the first floor and the second floor are different. The image processing device may display the camera coverage index of the first point when displaying the first floor, and display the camera coverage index of the second point when displaying the second floor.

It should be understood that in this implementation manner, the first point and the second point are only examples, and should not be understood as only displaying the camera coverage indicators of any two points in the first three-dimensional model. In practical applications, the image processing device may display camera coverage indicators of all points in the first three-dimensional model.

When the first point belongs to the first floor and the second point belongs to the second floor, it should not be understood that the camera coverage indicator can only be displayed at one point in the first floor, nor that it can only be displayed in the second floor A dot shows the camera coverage indicator. In practical applications, the camera coverage index can be displayed at one or more points on the first floor, and the camera coverage index can also be displayed at one or more points on the second floor.

As an optional implementation manner, before the image processing device displays the coverage index of the first camera at the first point, the following steps are further performed:

8. Obtain the third number of cameras on the first floor above.

In this embodiment of the present application, the third number is the number of cameras on the first floor.

In an implementation manner of acquiring the third number of cameras on the first floor, the image processing device uses the number of cameras on the first floor input by the user through the input component as the third number.

In another implementation manner of acquiring the third number of cameras on the first floor, the image processing device receives the number of cameras on the first floor sent by the terminal as the third number.

9. Obtain the coverage index of the first camera according to the ratio of the first quantity to the third quantity.

In the embodiment of the present application, the ratio of the first quantity to the third quantity=the first quantity/the third quantity. For example, if the first quantity is 10 and the third quantity is 30, then the ratio of the first quantity to the third quantity is 1/3.

Assume that the ratio of the first quantity to the third quantity is n ₃ , and the coverage index of the first camera is i ₁ . In a possible implementation, n ₃ and i ₁ satisfy the following formula:

i ₁ =k ₃ ×n ₃ +c ₃ (4)

Among them, k ₃ is a positive number, and c ₃ is a real number.

In another possible implementation, n ₃ and i ₁ satisfy the following formula:

Among them, k ₃ is a positive number, and c ₃ is a real number.

In yet another possible implementation, n ₃ and i ₁ satisfy the following formula:

i ₁ =(k ₃ ×n ₃ +c ₃ ) ² (6)

Among them, k ₃ is a positive number, and c ₃ is a real number.

Optionally, the image processing device acquires the fourth number of cameras on the second floor, and obtains the second camera coverage index according to a ratio between the second number and the fourth number.

As an optional implementation manner, the image processing device displays the first camera coverage index at the first point by performing the following steps:

10. Obtain a mapping relationship, the above mapping relationship represents the mapping relationship between the camera coverage index and the color.

In a possible implementation manner, the camera coverage index represented by green is larger than the camera coverage index represented by red.

In another possible implementation manner, the darker the color, the greater the coverage index of the camera.

In yet another possible implementation manner, the image processing apparatus obtains the first camera coverage index by performing step 8. The mapping relationship can be seen in the table below:

Camera Coverage Metrics	Pixel values
[0,0.1)	40
[0.1, 0.3)	80
[0.3, 0.5)	100
[0.5, 0.7)	140
[0.7, 0.8)	170
[0.8, 0.9)	200
[0.9, 1]	240

11. Determine the color of the first point according to the coverage index of the first camera.

12. Display the above-mentioned first point in the color of the above-mentioned first point.

As a possible implementation manner, the first camera is located on the first floor. In this embodiment, since the first camera is located on the first floor, the image processing device displays the first camera in the first three-dimensional model, that is, the image processing device displays the first floor in the first three-dimensional model.

In a possible implementation manner, the image processing apparatus displays the first floor in the first three-dimensional model by hiding floors in the first three-dimensional model except the first floor.

For example, the first three-dimensional model has five floors in total, and the first floor is the third floor in the first three-dimensional model. The image processing device can hide the fourth floor and the fifth floor in the first three-dimensional model, and then display the first floor while displaying the appearance of the first three-dimensional model. Since the first floor is the third floor, the first floor and the second floor will be covered when the first floor is displayed. In this way, when the first 3D model is displayed, the first floor and the second floor will be avoided. Display the resulting interference, thereby improving the display effect of the first floor.

Optionally, the image processing device acquires road network information of the first floor, and determines whether the first point belongs to the feasible area according to the road network information. When it is determined that the first point belongs to the feasible area, the step of displaying the coverage indicator of the first camera at the first point is performed, wherein the feasible area refers to an area where people can walk.

In this embodiment, the image processing device also performs the following steps:

13. When an instruction to display the second floor is detected, display the second floor in the first three-dimensional model.

In this step, the image processing device switches the floor displayed on the first three-dimensional model to the second floor when an instruction to display the second floor is detected.

The instruction to display the second floor may be an instruction input by the user to the image processing device through the input component. For example, when the image processing device displays the first 3D model and the floor information of the first 3D model on the display page, when the user touches the second floor in the floor information through the touch screen, the image processing device generates an instruction to display the second floor. For another example, when the image processing device displays the first 3D model and the floor information of the first 3D model on the screen, and the user clicks the second floor in the floor information with the mouse cursor, the image processing device generates an instruction to display the second floor.

The command to display the second floor may be a command generated when a condition for displaying the second floor is satisfied. For example, the condition for displaying the second floor is that the target object is present in the second floor. The image processing device determines that the target object appears on the second floor when determining that the image collected by the camera on the second floor contains the target object by comparing the image captured by the camera on the second floor with the image containing the target object, That is, it is determined that the condition for displaying the second floor is satisfied.

For example, image processing compares the image captured by the camera on the second floor with the face image of Zhang San and determines that the image captured by the camera on the second floor contains Zhang San, and determines that Zhang San appears in In the second floor, it is further determined that the condition for displaying the second floor is satisfied.

For another example, the condition for displaying the second floor is that a fire event occurs on the second floor. The image processing device determines that the condition for displaying the second floor is met when the image processing device determines that a fire event occurs on the second floor by processing the image collected by the camera in the second floor.

In a possible implementation manner, the image processing device displays the second floor in the first three-dimensional model by hiding floors in the first three-dimensional model except the second floor.

For example, the first three-dimensional model has five floors, and the second floor is the fourth floor in the first three-dimensional model. The image processing device can hide the fifth floor in the first three-dimensional model, and then display the second floor while displaying the appearance of the first three-dimensional model. Since the second floor is the fourth floor, the first, second and third floors will be covered when the second floor is displayed, so that when the first 3D model is displayed, the first, second and third floors The interference caused by the third floor to the display of the second floor, thereby improving the display effect of the second floor.

As an optional implementation manner, the image processing device further performs the following steps before performing step 102:

14. Obtain the target orientation of the first camera and the second three-dimensional model of the first camera, where the target orientation is the orientation of the first camera in the global positioning system coordinate system.

In another implementation manner of acquiring the target orientation of the first camera, the image processing apparatus receives the orientation of the first camera sent by the terminal as the target orientation.

In yet another implementation of acquiring the target orientation of the first camera, the image processing device acquires the orientation and coordinate transformation relationship of the first camera in the target scene, wherein the coordinate transformation relationship is the global positioning system coordinate system and the first three-dimensional model The conversion relationship between the coordinate systems. The image processing device converts the orientation of the first camera in the target scene into the orientation of the first camera in the first three-dimensional model according to the coordinate transformation relationship to obtain the orientation of the target.

In an implementation manner of acquiring the second 3D model of the first camera, the image processing apparatus uses the 3D model of the first camera input by the user through the input component as the second 3D model.

In another implementation manner of acquiring the second 3D model of the first camera, the image processing apparatus receives the 3D model of the first camera sent by the terminal as the second 3D model.

In yet another implementation manner of acquiring the second three-dimensional model of the first camera, the image processing device includes a laser radar. The image processing device uses the laser radar to scan the first camera to obtain the 3D model of the first camera as the second 3D model.

15. Taking the above-mentioned first position as the position of the above-mentioned second three-dimensional model in the above-mentioned first three-dimensional model, and taking the above-mentioned target orientation as the orientation of the above-mentioned second three-dimensional model in the above-mentioned first three-dimensional model, in the above-mentioned first three-dimensional model The above second 3D model is shown in .

In step 15, the image processing device determines the position of the second 3D model in the first 3D model according to the first position, and determines the orientation of the second 3D model in the first 3D model according to the orientation of the target, and then according to the second 3D model The position in the first three-dimensional model and the orientation of the second three-dimensional model in the first three-dimensional model display the second three-dimensional model in the first three-dimensional model, so as to achieve better display effect, so that the second three-dimensional model is displayed in the first three-dimensional model The display effect of the 2D and 3D models is more realistic. In addition, since the second 3D model can accurately display the first position (ie, the abscissa, ordinate and vertical coordinate of the first camera in the first 3D model), by displaying the second 3D model in the first 3D model, the The accuracy of the displayed position of the first camera.

Optionally, the display effect obtained by the image processing device by performing step 15 can be referred to in FIG. 2 .

As an optional implementation manner, the image processing device further performs the following steps before performing step 102:

16. Obtain the target orientation of the first camera and the image of the first camera.

In a possible implementation manner, the image of the first camera may be obtained by shooting the first camera.

After performing step 16, the image processing device performs the following steps in the process of performing step 102:

17. Display the image of the first camera in the first three-dimensional model according to the first position and the orientation of the target.
