The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic diagram of an architecture of a surveillance image processing system according to an embodiment of the present disclosure, where the system is suitable for performing cloud storage on a video surveillance image and a user equipment querying a data stream of video surveillance stored in the cloud storage. The system comprises a terminal 101, a server 102 and a user terminal 103.
The camera terminal 101 acquires a video monitoring image in real time; judging whether the content of the video monitoring image changes or not; if the content of the video image changes, acquiring a complete data stream of the video monitoring image, and sending the complete data stream to the server 102; if the content of the video image is not changed, acquiring an I frame data stream of the video monitoring image, and sending the I frame data stream to the server 102; or, acquiring I frame data streams of the video monitoring images at regular time and quantity according to preset time and preset data quantity, and sending the I frame data streams to the server. If the camera terminal 101 sets a fixed-time quantitative image acquisition, an I frame data stream of the video surveillance image is acquired according to a preset data volume at a defined preset time, and the I frame data stream is sent to the server 102.
After acquiring the video surveillance image, the camera terminal 101 stores the video surveillance image in a buffer queue. And judging whether the content of the video monitoring image changes or not by comparing the difference degree of the content of the video monitoring image in the buffer queue. The degree of difference can be determined by the degree of variation in the pixel values. The buffer queue can be a circular queue, so that the problem of data write-in overflow is avoided, and the data write-in reliability is improved. The camera terminal 101 may be connected to a local area network, and transmit the complete data stream or the I-frame data stream to the server through the local area network. Or, the camera terminal 101 determines whether the current system time is the same as the preset time, and if the timing set by the user is obtained quantitatively, obtains an I frame data stream of the video surveillance image when the current system time is the same as the preset time, and sends the I frame data stream to the server.

The I frame data stream corresponds to video content with unchanged or little change of the monitored video content, so that a plurality of I frame data streams can be spliced, and the generated miniature video data can reflect the monitored video content corresponding to a plurality of I frame data. The user terminal 103 can play back the thumbnail video data and the full video data stored in the server 102 by accessing the server 102. During playback, the user terminal 103 first sends a video query request to the server to obtain an index corresponding to the time information focused by the user. The video query request carries time information of user interest, and the server 102 provides an index of a response video stream for the user according to the time information. The user terminal 103 receives the index and outputs the index. The user selects one of the video data to play according to the index displayed by the user terminal 103, and when playing, the user terminal 103 triggers to send a pull request to the server 102, wherein the pull request contains the identifier of the video data that the user wants to view. The server 102 determines the storage address of the corresponding video data according to the identifier, obtains the video data through the storage address, and provides a pull stream service for the user terminal 103.
For example, the time information carried in the video query request sent by the user terminal 103 is 11: 30-12: 30. the server 102 inquired according to the time information, the target video data is 11:30-11:40 target video data A1, 11:40-11:50 target video data A2, 11:50-12:00 target video data A3, 12:00-12:10 target complete data stream B1, 12:10-12:20 target complete data stream B2 and 12:20-12:30 target complete data stream B3. The index of the target video data a1 is a1, the index of the target video data a2 is a2, the index of the target video data A3 is A3, the index of the target complete data stream B1 is B1, the index of the target complete data stream B2 is B2, and the index of the target complete data stream B3 is B3. The server 102 feeds back the indexes a1, a2, a3, b1, b2, and b3 to the user terminal 103. The user terminal 103 displays a1, a2, a3, b1, b2, and b3 as a video list. The user selects a certain video, for example, A3, according to the video list output by the user terminal 103, the pull request sent by the user terminal 103 to the server 102 carries A3, and the server 102 searches for the storage address of the target miniature video data A3 pointed by the index A3 according to the index A3. And acquiring target video data A3 according to the storage address, and feeding back the target video data A3 to the user terminal 103 to realize the pull streaming service provided for the user terminal 103.
