Embodiment Construction

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0037] see Figure 4 , the adaptive tracking method that is used to improve capture rate in the traffic velocity measuring system of the present invention, comprises the following steps:

[0038] According to the parameter information of the radar (the parameter information of the radar includes: the response cycle T of the radar and the detection distance range (that is, the first distance ΔR')) and the installation information of the radar on the road (the installation information of the radar on the road includes: the installation height and installation angle), calculate the size of the first distance ΔR' from when the vehicle normally enters the radar detection area to being captured by the camera, and feed back the size of the first distance Δ...

Abstract

The invention discloses a self-adaptive tracking method and system for improving the capture rate in a traffic speed measurement system. The method comprises the steps that according to the parameterinformation of radar and installation information of the radar on a road, a first distance delta R' from normal driving of a vehicle into a radar detection area to snapshot by a camera is calculated,and the first distance delta R' is fed back to the radar in real time; and the radar adjusts the tracking period of the radar to the measured vehicle according to the received first distance delta R'in combination with the driving speed of the measured vehicle. According to the invention, the capture rate of vehicle detection is improved.

Description

technical field [0001] The invention relates to the field of traffic speed measurement, in particular to an adaptive tracking method and system for improving the capture rate in a traffic speed measurement system. Background technique [0002] With the increasing number of vehicles, the number of traffic violations is also increasing, which brings great challenges to traffic operation management. The traditional traffic speed measurement system mainly consists of two parts, such as figure 1 As shown, it includes a camera module and a radar module. The radar module first detects the vehicle to be detected, and then uploads the vehicle distance, speed and other information to the camera, and the camera captures the vehicle according to the vehicle information. As a tool for detecting vehicle distance and driving speed, traffic speed radar transmits the detected vehicle movement information to the camera, and the camera captures the corresponding vehicles, effectively counting...
