Traffic roadside sensing system and method based on remote and close-range multi-sensor integrated fusion

The invention discloses a traffic roadside sensing system and method based on remote and close-range multi-sensor integrated fusion, and the method comprises the steps: enabling the transverse sensing range of a remote camera and a close-range camera to be larger than the width of a road through setting the pitch angle and the focal length of a camera; meanwhile, the optimal sensing range which can be achieved by mutual cooperation of the far-shot camera and the close-shot camera under the condition that the sensing area of the millimeter wave radar is known is deduced through a related geometric model. According to the invention, the effect of sensing the data redundancy of the overlapping area is achieved through the splicing and target detection of the far-shot and close-shot videos; and in cooperation with millimeter wave radar data, target state information is enriched, and related indexes are introduced to screen and match regions of interest of the multi-source sensor, so that the gain effect of mutual
