A method, apparatus, and medium for generating a display screen

Abstract

The present application discloses a method, device and medium for generating a display screen, which relates to the field of cameras. The monitoring screen initially displayed on the terminal display screen is a primary display screen obtained by intercepting the monitoring screen captured by a non-pan-tilt camera. When a monitoring screen movement instruction is received, the non-pan-tilt camera analyzes the monitoring screen movement instruction and sends the corresponding moving display screen to the terminal display screen. Since the primary display screen and the moving display sent by the non-pan-tilt camera to the terminal display screen are only a part of the monitoring screen, while expanding the monitoring display range, the transmission bandwidth required for the non-pan-tilt camera to display is also saved.

[0002] A camera, also known as a computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine, real-time monitoring, etc. A pan-tilt unit (PTZ) is a support device for installing and fixing a camera. The PTZ can receive PTZ commands. In security monitoring, PTZ is the abbreviation of Pan / Tilt / Zoom, which represents the omnidirectional (up and down, left and right) movement of the PTZ and the control of lens zooming and focusing. Through the PTZ, the shooting angle of the camera can be adjusted to expand the monitoring display range. However, for a non-PTZ camera based on a network protocol, the shooting scene is fixed. To obtain a larger monitoring screen, only the shooting range of the non-PTZ camera can be expanded. However, since the shooting range of the non-PTZ camera is expanded, the bandwidth required for the file stream transmitted to the terminal for display increases.

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0051] The core of the present application is to provide a method for generating a display screen to save the transmission bandwidth required for non-pan-tilt camera display.

[0052] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] Since the shooting scene of a non-pan-tilt camera based on a network protocol is fixed, if a larger monitoring range is to be obtained, only the shooting range of the non-pan-tilt camera can be expanded. However, if the shooting range of the non-pan-tilt camera is expanded, the transmission bandwidth required for the file stream transmitted to the terminal for display increases. In order to save the transmission bandwidth required for non-pan-tilt camera display, Figure 1 The following is a flowchart of a method for generating a display screen provided for an embodiment of the present application, as Figure 1 shown, including:

[0054] S11: Receive the primary display screen sent by the non-pan-tilt camera, where the non-pan-tilt camera obtains the primary display screen after intercepting the captured monitoring screen;

[0055] S12: Display the primary display screen on the terminal display screen;

[0056] S13: Receive a monitoring screen movement instruction;

[0057] S14: Send the monitoring screen movement instruction to the non-pan-tilt camera so that the non-pan-tilt camera can parse the monitoring screen movement instruction;

[0058] S15: Receive the moving display screen sent by the non-pan-tilt camera and display the moving screen on the terminal display screen, where the non-pan-tilt camera generates the moving display screen based on the monitoring screen movement instruction on the basis of the primary display screen.

[0059] The non-pan-tilt camera mentioned in this embodiment refers to a camera with a fixed shooting angle and no pan-tilt installation. The non-pan-tilt camera cannot move the shooting angle, and the picture taken by the camera displayed on the corresponding terminal is usually fixed. The monitoring picture cannot be moved up, down, left, right, zoomed in or out, etc. This application does not limit the applicable scenarios and types of non-pan-tilt cameras, such as wide-angle cameras, zoom cameras, telephoto cameras, etc. The non-pan-tilt camera realizes data transmission based on the Open Network Video Interface Forum (ONVIF) network video protocol. This embodiment does not limit the specific number of non-pan-tilt cameras. It can be one camera, and the monitoring picture is the picture taken by one camera; it can also be composed of multiple cameras, and the monitoring picture is a composite picture of the pictures taken by multiple cameras. This embodiment does not make specific restrictions.

[0060] The terminal display screen mentioned in this embodiment refers to the display device of the terminal platform for displaying the primary display image sent by the non-pan-tilt camera. This embodiment does not limit the connection method between the non-pan-tilt camera and the terminal platform, and can be designed according to actual conditions.

[0061] In addition, the monitoring screen movement instruction mentioned in this embodiment refers to the one issued by the operator. After the central processor of the terminal platform receives the monitoring screen movement instruction, it sends the monitoring screen movement instruction to the non-pan-tilt camera. The non-pan-tilt camera parses the monitoring screen movement instruction, generates the corresponding mobile display screen, and transmits it to the terminal platform and displays it on the terminal display screen.

[0062] Step S11 mentions that the non-pan-tilt camera will capture the surveillance image and obtain a primary display image after interception and processing. This embodiment does not specifically limit how to intercept and process the surveillance image. It can be designed according to actual needs. For example, the primary display image is intercepted at a preset size based on the center of the surveillance image; the preset size image is intercepted based on the edge of the surveillance image.

[0063] The moving display screen mentioned in step S15 is generated by the non-pan-tilt camera according to the monitoring screen movement instruction. If the monitoring screen movement instruction indicates up and down movement, the moving display screen is generated by the non-pan-tilt camera moving up and down on the basis of the primary display screen. Similarly, if the monitoring screen movement instruction indicates left and right movement, the moving display screen is generated by the non-pan-tilt camera moving left and right on the basis of the primary display screen. If the monitoring screen movement instruction indicates enlarging the screen, the moving display screen is generated by the non-pan-tilt camera enlarging a partial area of the primary display screen on the basis of the primary display screen. Similarly, if the monitoring screen movement instruction indicates reducing the screen, the moving display screen is generated by the non-pan-tilt camera reducing a partial area of the primary display screen on the basis of the primary display screen. It should be noted that the convenience rate of the moving display screen and the primary display screen is the same. For example, the size of the monitoring screen captured by the non-pan-tilt camera is 4096×2160, and the size of the intercepted primary display screen is 1920x1080. If the monitoring screen movement instruction indicates displacement movement (upward movement, downward movement, leftward movement, rightward movement, etc.), the moving display screen is a 1920x1080 screen generated by displacing on the basis of the primary display screen. If the monitoring screen movement instruction indicates enlarging or reducing, the moving display screen is a screen enlarged or reduced to the size of 1920x1080 within a specified range or a preset range on the basis of the primary display screen. Among them, the specified range refers to the specified reduction or enlargement area sent by the terminal platform to the non-pan-tilt camera; the preset range means that if the terminal platform does not specify an area, the non-pan-tilt camera reduces or enlarges the primary display screen according to the preset area.

[0064] Specifically, the terminal platform receives the primary display screen sent by the non-pan-tilt camera and displays the primary display screen on the terminal display screen. Among them, the primary display screen is obtained by intercepting the monitoring screen captured by the non-pan-tilt camera; when receiving the monitoring screen movement instruction, the terminal platform sends the monitoring screen movement instruction to the non-pan-tilt camera, the non-pan-tilt camera parses the monitoring screen movement instruction, and the moving display screen sent by the non-pan-tilt camera according to the monitoring screen movement instruction is displayed on the terminal display screen.

[0065] Through the display screen generation method provided in this embodiment, the monitoring screen initially displayed on the terminal display screen is the primary display screen obtained by the non-pan-tilt camera intercepting the captured monitoring screen. When receiving the monitoring screen movement instruction, the non-pan-tilt camera parses the monitoring screen movement instruction and sends the corresponding moving display screen to the terminal display screen. Since the primary display screen and the moving display sent by the non-pan-tilt camera to the terminal display screen are only part of the monitoring screen, through the method provided in this application, while expanding the monitoring display range, the transmission bandwidth required for the non-pan-tilt camera to display is also saved.

[0066] According to the above embodiments, if there is only one non-pan-tilt camera, the present embodiment provides a preferred solution. The non-pan-tilt camera mentioned in step S11 obtains a primary display screen after intercepting the captured surveillance image, including:

[0067] Intercept a screen of a preset size from the physical center of the surveillance image to generate a primary display screen.

[0068] When there is one non-pan-tilt camera, the non-pan-tilt camera intercepts a screen of a preset size from the physical center of the captured surveillance image to obtain a primary display screen. The present embodiment does not limit the shape of the surveillance image captured by the non-pan-tilt camera. For example, if the surveillance image captured by the non-pan-tilt camera is circular, the center of the circle is the physical center of the surveillance image; if the surveillance image captured by the non-pan-tilt camera is square, the center of the square is the physical center. In addition, the primary display screen obtained by intercepting the surveillance image can be circular or polygonal. The present embodiment does not make specific limitations and can be designed according to actual needs.

[0069] Specifically, the non-pan-tilt camera captures a surveillance image, performs an interception process on the surveillance image to obtain a primary display screen, and the terminal platform receives the primary display screen sent by the non-pan-tilt camera. Since the primary display screen sent by the non-pan-tilt camera to the terminal display screen and the mobile display are only part of the surveillance image, while expanding the surveillance display range, it also saves the transmission bandwidth required for the non-pan-tilt camera display.

[0070] According to the above embodiments, the surveillance range captured by a single surveillance camera is limited. In order to monitor a larger range, the present embodiment provides a preferred solution. If there are multiple non-pan-tilt cameras, the non-pan-tilt cameras mentioned in step S11 obtain a primary display screen after intercepting the captured surveillance images, including:

[0071] Stitch the sub-surveillance images captured by multiple non-pan-tilt cameras to obtain a surveillance image;

[0072] Intercept a screen of a preset size from the physical center of the surveillance image to generate a primary display screen.

[0073] The multiple non-pan-tilt cameras mentioned in the present embodiment refer to non-pan-tilt cameras whose captured images can be processed to obtain a complete and larger range. The sub-surveillance images mentioned in the present embodiment are the surveillance images captured by multiple non-pan-tilt cameras.

[0074] The multiple non-pan-tilt cameras mentioned in the present embodiment can be regarded as a non-pan-tilt camera system, and the surveillance image captured by it is obtained by stitching the sub-surveillance images captured by multiple non-pan-tilt cameras.

[0075] Specifically, multiple non-pan-tilt cameras capture sub-monitoring images. After stitching the sub-monitoring images, a complete monitoring image is obtained. A preset-sized image is intercepted from the monitoring image with the physical center as the center, resulting in a primary display image. The shape of the monitoring image is not limited in this embodiment. For example, if the monitoring image is circular, the center of the circle is the physical center of the monitoring image; if the monitoring image is square, the center of the square is the physical center. Additionally, the primary display image obtained by intercepting the monitoring image can be circular or polygonal. This embodiment does not make specific restrictions and can be designed according to actual needs.

[0076] Specifically, multiple non-pan-tilt cameras capture sub-monitoring images. After stitching the sub-monitoring images, a complete monitoring image is obtained. A preset-sized image is intercepted from the monitoring image with the physical center as the center, resulting in a primary display image. Since the primary display image and the mobile display sent by the non-pan-tilt camera to the terminal display screen are only part of the monitoring image, while expanding the monitoring display range, the transmission bandwidth required for the non-pan-tilt camera display is also saved.

[0077] According to the above embodiments, this embodiment provides a preferred solution. The monitoring image movement instruction includes: a movement instruction and a zoom instruction.

[0078] Correspondingly, the non-pan-tilt camera mentioned in step S15 generates the mobile display image based on the primary display image according to the monitoring image movement instruction, including:

[0079] Analyze the movement instruction and the zoom instruction:

[0080] Perform movement processing and zoom processing on the primary display image to generate the mobile display image.

[0081] The movement instruction refers to a displacement instruction, and the zoom instruction refers to a reduction or enlargement instruction. The monitoring image movement instruction includes both of these instructions. The non-pan-tilt camera analyzes the monitoring image movement instruction and sends the corresponding mobile display image after displacement and enlargement processing to the terminal display screen. Additionally, the zoomed image mentioned in this embodiment can be displayed in the form of a picture-in-picture or directly display the final enlarged image. This embodiment does not make specific restrictions.

[0082] The non-pan-tilt camera receives the monitoring image movement instruction, analyzes the movement instruction and the zoom instruction: performs movement processing and zoom processing on the primary display image according to the movement instruction and the zoom instruction to generate the mobile display image. By the method provided in this embodiment, the problem of first sending a movement instruction and then sending a zoom instruction and displaying the operation results step by step is avoided. The non-pan-tilt camera directly sends the final display result, improving the control and display speed.

[0083] In addition, this embodiment also provides a preferred solution, wherein the monitoring screen movement instruction further includes: an operation center instruction;

[0084] Correspondingly, the non-PTZ camera generates a moving display image based on the primary display image according to the monitoring image movement instruction, including:

[0085] Parsing move commands, zoom commands and operation center commands:

[0086] The primary display image is moved and scaled with the area represented by the operation center instruction as the center to generate a moving display image.

[0087] The operation center instruction mentioned in this embodiment refers to an operation area specified by an operator or a default operation area of a terminal platform, and the primary display screen is moved and zoomed with the operation area as the center.

[0088] The non-PTZ camera receives a surveillance image movement command, parses the movement command, zoom command, and operation center command, and performs movement and zoom processing on the primary display image based on the movement and zoom commands, centered on the area indicated by the operation center command, to generate the moving display image. The method provided in this embodiment avoids the problem of first sending the surveillance image movement command and then displaying the surveillance image in steps. The non-PTZ camera directly sends the final display result, improving control and display speed.

[0089] According to the above embodiment, this embodiment provides a preferred solution, such as Figure 2 As shown, step S11: receiving the primary display image sent by the non-pan-tilt camera, including:

[0090] S111: receiving a file stream of a real-time slice or a video-on-demand slice sent by a non-pan-tilt surveillance camera;

[0091] S112: Parse the file stream to obtain a primary display screen.

[0092] The real-time slicing mentioned in this embodiment means that the non-pan-tilt camera only saves the set number of slices N for fixed storage. When the saved file reaches the number of slices, it will be re-counted, the old slices will be removed, and a new index file will be generated. The non-pan-tilt camera will transmit the file that has reached the number of slices to the terminal platform for display on the terminal display screen. The non-pan-tilt camera will update the captured monitoring screen in real time, and send the monitoring screen to the terminal platform after processing. This embodiment does not limit the format of the file stream transmitted to the terminal platform. If the terminal platform sends a monitoring screen movement instruction to the non-pan-tilt camera, the non-pan-tilt camera will parse the monitoring screen movement instruction and generate a corresponding mobile display screen output to the terminal platform.

[0093] The captured surveillance footage is processed through real-time slicing by a non-pan-tilt camera and transmitted to the terminal platform for display, achieving real-time updates of the surveillance footage. Since the primary display image and the mobile display sent by the non-pan-tilt camera to the terminal display are only part of the surveillance footage, it not only expands the surveillance display range but also saves the transmission bandwidth required for the non-pan-tilt camera display.

[0094] The on-demand slicing mentioned in this embodiment refers to generating the number of slices at preset time intervals, and the slice files are always saved. If the terminal platform sends a request to the non-pan-tilt camera to view the surveillance footage, the non-pan-tilt camera will transmit the stored files to the terminal platform.

[0095] Specifically, the non-pan-tilt camera outputs the processed surveillance footage stored through on-demand slicing to the terminal platform for display. If the terminal platform sends a surveillance footage movement instruction to the non-pan-tilt camera, the non-pan-tilt camera parses the surveillance footage movement instruction and generates a corresponding mobile display image for output to the terminal platform.

[0096] Through the method provided in this embodiment, users can view the surveillance footage of the past time period. Since the primary display image and the mobile display sent by the non-pan-tilt camera to the terminal display are only part of the surveillance footage, it not only expands the surveillance display range but also saves the transmission bandwidth required for the non-pan-tilt camera display.

[0097] Step S112 parses the file stream to obtain the primary display image.

[0098] After the terminal platform receives the real-time slice file stream or the on-demand slice file stream sent by the non-pan-tilt camera, it parses the file stream through the ONVIF protocol to obtain a video stream that can be used for playback. Through the ONVIF protocol, communication connection is achieved between the terminal platform and the non-pan-tilt camera, without being restricted by the inconsistent interface protocols between different non-pan-tilt cameras.

[0099] According to the above embodiment, this embodiment provides a preferred solution. As Figure 3 shown, sending the surveillance footage movement instruction to the non-pan-tilt camera mentioned in step S14 includes:

[0100] Step S141: Send a request to the interface of the non-pan-tilt camera;

[0101] Step S142: Obtain the stream address of the non-pan-tilt camera;

[0102] Step S143: Send the surveillance footage movement instruction to the non-pan-tilt camera according to the stream address.

[0103] In this embodiment, a request is sent to the interface of a non-pan-tilt camera. Since the non-pan-tilt camera is based on the ONVIF protocol, communication connection with the non-pan-tilt camera can be achieved through the ONVIF protocol, without being restricted by the inconsistent interface protocols between different non-pan-tilt cameras.

[0104] The terminal platform sends a request to the interface of the non-pan-tilt camera through the ONVIF protocol. After receiving the interface send request, the non-pan-tilt camera sends a stream address to the terminal platform, so that the terminal platform can send a monitoring screen movement instruction, enabling communication connection between the terminal platform and the non-pan-tilt camera, without being restricted by the interface protocol of the non-pan-tilt camera.

[0105] To enable those skilled in the art to understand the technical solution of this application, the following describes the application of the method for generating a display screen in an actual scenario. For example Figure 4 As shown, this method is mainly applied to the terminal platform side and the non-pan-tilt camera side;

[0106] S41: The non-pan-tilt camera side obtains a primary display screen after intercepting the captured monitoring screen;

[0107] S42: The non-pan-tilt camera side sends the primary display screen;

[0108] S43: The terminal platform side receives the primary display screen and displays the primary display screen on the terminal display screen;

[0109] S44: The terminal platform side receives a monitoring screen movement instruction;

[0110] S45: The terminal platform side sends a monitoring screen movement instruction;

[0111] S46: The non-pan-tilt camera side receives the monitoring screen movement instruction;

[0112] S47: The non-pan-tilt camera side analyzes the monitoring screen movement instruction and generates a moving display screen based on the primary display screen according to the monitoring screen movement instruction;

[0113] S48: The non-pan-tilt camera side sends the moving display screen;

[0114] S49: The terminal platform side receives the moving display screen and displays the moving screen on the terminal display screen.

This application also provides an embodiment corresponding to the device for generating a display screen. It should be noted that this application describes the embodiments of the device part from two perspectives, one is from the perspective of functional modules, and the other is from the perspective of hardware.

The updated display module 55 receives the moving display screen sent by the non-pan-tilt camera according to the monitoring screen movement instruction and displays the moving screen on the terminal display screen. Since the primary display screen and the moving display sent by the non-pan-tilt camera to the terminal display screen are only part of the monitoring screen, while expanding the monitoring display range, it also saves the transmission bandwidth required for the non-pan-tilt camera to display.

[0123] Through the display screen generation device provided by this embodiment, the monitoring screen initially displayed on the terminal display screen is the primary display screen obtained after intercepting the captured monitoring screen by the non-pan-tilt camera.
