Highway pedestrian crossing time prediction method, system, equipment and medium

Abstract

The invention provides a highway pedestrian crossing time prediction method, a highway pedestrian crossing time prediction system, highway pedestrian crossing time prediction equipment and a medium. Estimating a preliminary prediction result of road crossing of the pedestrians, continuously acquiring real-time information of road crossing of the pedestrians, predicting based on a Kalman filtering trajectory to obtain a real-time prediction result of road crossing of the pedestrians, and comparing the difference between the preliminary prediction result and the real-time prediction result to form a combined prediction method; sufficient safety margin can be provided for vehicles receiving active safety early warning, the probability of occurrence of collision between the vehicles running on the expressway and operating personnel or illegal crossing personnel is reduced, and the road safety is improved; the pedestrian crossing time can be predicted, the pedestrian movement can be monitored in real time, and the requirements of pedestrian safety, pedestrian movement randomness and vehicle active collision avoidance are met while the prediction precision is met; safety of vehicles and pedestrians on the expressway is facilitated, and new safety protection measures are provided for the vehicles and the pedestrians.

Description

technical field [0001] The invention relates to the technical field of active safety, in particular to a method, system, equipment and medium for predicting pedestrian crossing time on a highway. Background technique [0002] In the expressway scene, the vehicle travels at a fast speed, and when passing through villages and towns or construction areas, pedestrians and operators who illegally climb over the guardrail or cross the central isolation belt often appear and appear, which is likely to cause serious vehicle-person conflicts. Some data show that vehicle-person collisions account for up to 28% of all highway traffic accidents, and the fatality rate is about 65%. Studies have shown that active safety control of vehicles with the help of V2X technology can effectively reduce the number and severity of vehicle-person collisions. One of the core technologies is pedestrian trajectory prediction. [0003] The current research on vehicle-human active collision avoidance app...
