Embodiment Construction
[0035] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.
[0036] The general idea of the present invention is to start from the place where the event occurred, search for multiple shortest paths within the radius D of the set range based on the road network, find out the front-end devices on these paths according to all the nodes and paths obtained, and for a video review. It is possible to more accurately find the front-end equipment that requires video viewing, which reduces the workload of video viewing and improves work efficiency.
[0037] like figure 1 As shown, a road network-based video tracking method in this embodiment includes:
[0038] Step S1, determine the point on the road closest to the place where the incident occurred in the road network as the starting point, and sea...
