Embodiment Construction
[0101] The hardware equipment required by the present invention includes a video collector and a video processor. Set up a standard video collector (such as a camera, etc.) on an overpass in an urban expressway section, and adjust its position so that it is aligned with the lane to be detected and recognized. The captured video signal is sent to a video processor (usually a personal computer). In the algorithm implementation part of the software, related interfaces such as Opencv and Directshow can be used to realize the video reading and preprocessing part, and Matlab and other tools are called in Visual C++2008 to complete the processing and calculation of the matrix, the realization of the SVM part and the integration of the system Debugging works.
[0102] Based on the video collected on the urban expressway, the present invention extracts the time-space line sequence symbol that can represent the time-space information from the video, then performs data compression and f...
