Abstract

Embodiments of the present invention provide a method, device, medium, and electronic device for associating radar measurement data with vehicle trajectories, so as to solve the problem in the prior art that vehicles in a stationary queue cannot be detected. The measured data set and the measured target vehicle trajectory; according to the sub-area joint effective measurement probability matrix in the vicinity of the predicted position of the target vehicle obtained by pre-training, the relationship between the measured data in the measured data set and the target vehicle trajectory is calculated; if the measurement If there is no measurement data associated with the trajectory of the target vehicle in the data set, it is judged that the measurement data in the measurement data set are all invalid, and it is judged that the target vehicle is a preset stationary vehicle.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device, medium and electronic device for associating radar measurement data with vehicle tracks. Background technique [0002] With the improvement of the economy and people's living standards, the sharp increase in the number of private cars has made the problem of urban traffic congestion increasingly prominent. The intersection is the key point of the whole traffic network control, the effective monitoring and control of the traffic at the intersection can improve the performance of the whole traffic network. Our country started relatively late in the research and application of urban traffic signal control. On the one hand, we learned from foreign advanced control technologies, and on the other hand, we independently developed related traffic signal control systems. A relatively complete traffic signal control system has been established. Since the 1980s, ...
