The embodiment of the invention provides a radar measurement data and vehicle trajectory association method and device, a medium and an electronic device which are used for solving the problem that static queuing vehicles cannot be detected in the prior art. The method comprises the following steps: obtaining a measurement data set obtained by a radar at the current moment and a measured target vehicle trajectory; calculating an incidence relation between measurement data in the measurement data set and a target vehicle trajectory according to a pre-trained sub-region joint effective measurement probability matrix of a region adjacent to the prediction position of a target vehicle; and if the measurement data associated with the trajectory of the target vehicle does not exist in the measurement data set, judging that the measurement data in the measurement data set is invalid, and judging that the target vehicle is a preset vehicle tending to be static.
Description
technical field [0001] The present 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 trajectories. 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. Sin...
