Problems solved by technology
[0004] If you only rely on video AI recognition technology, you often need to perform feature matching calculations on a large number of videos. This method requires strong computing power support, consumes a lot of computing resources, and may retrieve a large number of targets with the same features, resulting in extremely unstable tracking effects. , poor video transitions
Combining the relationship between the road network and monitoring greatly reduces the amount of calculation, but because it judges based on the spatial relationship, it does not consider the visual range of monitoring, and there may be cases where the camera is only close in space and does not cover the required area.

The present invention relates to the technical field of video tracking, and discloses a video tracking method and system based on pixel spatial resolution. The video tracking method and system based on pixel spatial resolution of the present invention calculates the spatial visual range of monitoring and monitors the monitoring screen. Divide the grid and calculate the spatial resolution, determine the predictive monitoring in combination with the predicted area, and filter the target monitoring through the spatial resolution threshold to ensure that the target monitoring shot can identify and track the target in the predicted area picture, and eliminate invalid monitoring, which can greatly reduce the amount of calculation and improve The efficiency of video tracking provides strong support for urban monitoring, early warning and handling of emergencies.
Description
technical field [0001] The present invention relates to the technical field of video tracking, in particular to a video tracking method and system based on pixel spatial resolution. Background technique [0002] With the development of the city, the surveillance deployed in the city is becoming more and more intensive, and the video network built is becoming more and more perfect. These surveillance videos provide important information resources for urban management. The use of urban monitoring, through the calculation and analysis of the monitoring screen, to realize the tracking of personnel, vehicles and other elements has become an important technical means of smart city governance, how to efficiently and accurately track video becomes more and more important. [0003] At present, based on related technologies such as computer vision and deep learning, the use of computers can realize target detection, recognition and tracking of objects in surveillance videos. In the p...
