Abstract

The invention discloses a synchronization method, device, device and system for improving video data stream frames. According to the size of the video frame, a buffer space is adaptively applied; when the current frame data transmission ends, a first end interrupt signal INT1 is generated; Once the current frame data transmission in the interrupt signal INT1 ends, the interrupt is terminated, and the current frame data is obtained from the corresponding buffer area. After image algorithm processing is performed on the current frame data, the processing result is transmitted to the buffer area, and the transmission of the pending result is completed. The current frame result is generated, and the second end interrupt signal INT2 is transmitted; the transmission completion interrupt is completed according to the processing result, and the time difference Tp between the first end interrupt signals INT1 and INT2 is calculated, and linear segmentation processing is performed according to the size of the time difference Tp. The invention can adaptively improve the video data frame and improve the frame synchronization output precision.

Description

technical field [0001] The invention relates to the field of video image processing, and particularly discloses a synchronization method, device, device and system for improving video data stream frames. Background technique [0002] With the development of modern information technology, video image processing technology has developed very rapidly. Increasing the frame rate of video images can acquire or display more and more detailed image information. Especially in the industrial and military fields, the real-time requirements for video and image processing are very high. In order to meet this feature, high frame rate machine vision equipment is often used to obtain the motion features and trajectories of fast-moving objects. Although rich motion details are obtained, it increases the difficulty and complexity of frame synchronization processing of high frame rate video data. In general, the transmission throughput problem of high frame rate video data can be solved by in...
