Abstract

The present invention provides a vehicle trigger capture method and system, wherein the above method includes: obtaining the vehicle density of vehicles in the target area; Sending a working mode switching signal, wherein the working mode switching signal is used to instruct the image acquisition device and / or the radar to use the working mode corresponding to the vehicle density to trigger and capture the vehicles in the target area, When the vehicle density is higher than the first threshold, only the image acquisition device is used to trigger and capture the vehicles in the target area. The above technical solution solves the problem of vehicle density on the road in related technologies. In the case of high, the recognition accuracy and recognition efficiency of the radar to the vehicle are not high.

Description

technical field [0001] The present invention relates to the field of millimeter-wave radar, in particular to a method and system for triggering and capturing images of vehicles. Background technique [0002] At present, commonly used snapshot recognition systems on expressways generally have a radar speed measurement module and a video recognition module. The former is used to measure the driving speed of the vehicle, and the latter is used to recognize the license plate of the speeding vehicle, and the radar speed measurement module is limited by the speed of the vehicle. state (for example, speed, car following, parallel, vehicle length, etc.), of course, in the application field with high requirements for vehicle capture and license plate recognition, video recognition equipped with radar speed measurement is no longer sufficient for vehicle capture and identification of the entire section. identify. [0003] Related technologies can only perform a single trigger capture...
