Embodiments of the invention

In the following description, for purposes of illustration and description However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the application.

In order to explain the technical solutions described in the present application, the following description will be made by way of specific embodiments.

FIG. 1 is a schematic diagram of a transmission scenario of a surveillance video according to an embodiment of the present disclosure, where the scenario includes a monitoring terminal and a video image collection terminal, where:

The monitoring terminal may be a server monitoring center, a desktop computer terminal or a mobile terminal, and the monitoring terminal may receive video images of multiple video image collecting ends through multiple code stream channels, and may simultaneously display multiple images through an image array. The video image is convenient for the monitoring staff to monitor multiple scenes at the same time.

The video image collecting end may include a camera, a processor, a memory, and a communication circuit, and the camera may be used to capture a high-definition video image, and the processor may perform rate conversion on the high-definition video image to obtain two different Rate video image. For example, a 720P high-definition code stream can be obtained, and the corresponding code rate is about 4 Mbps, and the code rate of the other video image can be 700 Kbps, and the obtained video images of different code rates are respectively stored in the memory. One or two video images can be selected for transmission through a communication circuit in combination with a video image selection command.

FIG. 2 is a schematic flowchart of an implementation process of a monitoring video transmission method according to an embodiment of the present disclosure, which is as follows:

In step S201, the video image is acquired by the camera, and the acquired video image is converted into a video image of a first code rate and a video image of a second code rate, where the first code rate is less than the second code rate;

Specifically, the camera of the present application may include a high-definition camera, and the obtained video image has higher definition and code rate, and more network bandwidth is required for transmitting the video image. Of course, the camera may also include a microphone to collect audio data, and the collected audio data may also be high-fidelity audio.

When the video image acquired by the camera is converted into a video image of a first code rate and a video image of a second code rate, the following situations may be included:

1. The video image captured by the camera is a video image of a second code rate, and the video image of the first code rate is converted according to the video image of the second code rate. Wherein, the second code rate is greater than the first code rate, and more image details are included in the video image of the second code rate, and the video image of the second bit rate can be converted to the first code rate by sacrificing image details. Video image, although the video image of the first bit rate loses more detail, but still includes the main content in the video image, and plays the video image of the first bit rate and the video of the second bit rate in the image array. When the image is used, the user generally cannot feel the obvious difference.

2. The video image captured by the camera is a video image of the original code rate, and the video image of the original code rate is subjected to rate conversion to obtain a video image of the first code rate and a video image of the second code rate, and the first The code rate is less than the second code rate, and the second code rate is less than the original code rate. The second code rate can be adjusted according to the transmission speed of the communication circuit of the video image collecting end. For example, when the communication circuit is a 3G communication circuit or a 4G communication circuit, the corresponding transmission speed is also different.

In step S202, when the video attention instruction is not received, the video image of the first code rate is transmitted to the monitoring end in real time;

The video attention instruction may be sent by the monitoring end. When the monitoring end is a video of multiple channels simultaneously displayed on the same display screen, the attention instruction may be a video screen input by the user to one of the channels. Select the command, or the user's zoom instruction for the video screen of a channel.

Of course, the video attention instruction is not limited to the above two types, and the user's attention instruction to the video may be generated by means of marking or by setting a menu option.

When the video image acquisition end does not receive the attention instruction, the video image of the first code rate can be transmitted to the monitoring end, and the video image occupied by the first code rate occupies less network resources, saving the need for transmitting the video image. The traffic can be played in real time on the monitoring end, and when it is in the small window playing state, the difference between the played video image of the first bit rate and the video image of the second bit rate cannot be obviously perceived.

In step S203, when the video attention instruction is received, the video image of the second code rate is transmitted to the monitoring terminal.

When the video attention instruction is received, the video image of the second bit rate is transmitted to the monitoring end, so that the monitoring end can view and analyze the details of the image according to the video image of the second bit rate with higher resolution.

Certainly, after the monitoring terminal sends the instruction of the video image, the attention of the video image may be cancelled, and the video cancellation cancellation instruction is sent to the monitoring end, and the monitoring terminal reselects the first code according to the attention cancellation instruction. The rate of video images is transmitted.

The video attention cancellation instruction may be generated when the enlarged video image is reduced.

The present invention obtains video images of two different code rates by performing rate conversion on the video images acquired by the camera, and transmits a video image of a higher bit rate to the monitoring end when receiving the video attention instruction, and does not receive the video. When attention is paid to the instruction, the video image of the lower bit rate is transmitted, so that the system can transmit the video image of the lower bit rate obtained by the conversion, which can effectively save network resources, reduce the flow rate, and can also observe in real time. The video image and the high bit rate picture of the video image of interest can be obtained, which is convenient for the monitoring personnel to acquire the detailed image.

3031. Determine a video segment including the time point according to a time point when the video attention instruction is received;

The time point may be the time end point of the video segment, the forward time is searched for a predetermined duration, the starting point of the video segment is determined, and the video segment is determined according to the starting point and the ending point.

3032. Determine the object that has changed as an abnormal object by comparing the image frame in the video segment, or determine that the image of the person in the image is an abnormal object.

By comparing the image frames of the video clips, an object that changes in the video image frame is determined, such as an object that has a position change in the video frame image or an artificial abnormal object. Alternatively, the portrait image included in the image frame in the video segment may be searched according to the portrait feature, and the portrait in the video segment is regarded as an abnormal object.

In step S304, searching for a start time of the abnormal object in the video image of the second code rate according to the abnormal object;

After determining the abnormal object, the feature information of the abnormal object, such as a shape feature, a color feature, or the like of the abnormal object, may be used to search for the abnormal object in the video image of the second code rate by using the feature information. The start time to be able to determine when an abnormal event occurs.

In step S305, the video image of the found start time and/or the second code rate corresponding to the start time is sent to the monitoring end.

The video interception is performed on the second code rate of the video image collecting end according to the occurrence time of the abnormal event, so that the monitoring terminal can see the time point when the abnormality starts to occur, so that the abnormality can be analyzed quickly and effectively.

In addition, as a preferred embodiment of the present application, when a plurality of cameras are included in the scene, the method may further include the steps of joint image analysis as shown in FIG. 4, including:

In step S401, acquiring a first location corresponding to the camera that receives the video attention instruction;

The position of the camera corresponding to the video image of each channel is pre-registered, and when the video attention instruction for the video image of one of the channels is received, the first position of the corresponding camera may be determined according to the video attention instruction.

In step S402, searching for a neighboring video image of a second code rate captured by a camera adjacent to the first location;

And searching for other cameras adjacent to the first position of the camera corresponding to the video attention instruction, and acquiring other cameras, according to the first position of the camera corresponding to the determined video attention instruction, in the position of the registered camera A second video rate of adjacent video images is taken.

In step S403, it is detected whether an abnormal object is included in the adjacent video image, and the video segment including the abnormal object is sent to the monitoring end.

Searching for whether the abnormal object is included in the adjacent video image by using a predetermined abnormal object may perform a search within a predetermined predetermined time period starting from the current time to determine whether an abnormal object is included, and if the abnormal object is included, intercepting The video clip including the abnormal object is sent to the monitoring end, so that the monitoring terminal can fully understand the scene condition.
