Traffic flow microscopic simulation method and system based on UAV image analysis

The invention discloses a traffic flow microscopic simulation method and system based on UAV image analysis. Relates to the technical field of analogue simulation, and discloses a traffic microscopic simulation method, which comprises the following steps of: introducing a UAV image to penetrate through the whole traffic flow microscopic simulation process, acquiring a whole traffic organization in a multi-intersection region, fully automatically restoring vehicle running track points in the region by using the UAV image, and applying to each link of traffic microscopic simulation based on analysis of vehicle running track point information. A scientific data basis is provided for OD input, parameter calibration and operation check of traffic simulation, and the precision and accuracy of a simulation model are improved; the real driving track of the vehicle is advanced, the vehicle running characteristics in the area and the traffic demand distribution in the traffic can be restored to the maximum extent, the
