The invention discloses a left-turn human-vehicle interaction risk assessment method and system based on an unmanned aerial vehicle video, and relates to the technical field of traffic safety. Starting from three aspects of a man-vehicle blind area field, a potential energy field and a future possible operation space field, the safety risk of a man-vehicle interaction scene in the left turning process of a vehicle is comprehensively evaluated; video data are collected in real time through the unmanned aerial vehicle technology, and the traffic data collection efficiency and accuracy are improved. A target detection and tracking algorithm is utilized to more accurately extract the feature information of the vehicle and the pedestrian, so that the evaluation precision of the left-turn human-vehicle interaction risk is improved, and the human-vehicle interaction condition is fed back in real time; based on the blind area field risk quantity, the potential energy field risk quantity and the future possible operation space field risk quantity, a left-turn human-vehicle interaction risk assessment result is determined, mutual influence and action mechanisms of different factors are comprehensively considered, scientific basis and suggestions can be provided for traffic management departments and related decision makers, the traffic accident rate is reduced, and the risk assessment efficiency is improved. And the driving safety is improved.
