An integrated device and method for intelligent capture of emergency lanes based on radar technology

Abstract

The invention discloses a radar technology-based intelligent capture integrated device and method for emergency lanes, comprising a radar speed measurement module, a capture module and a computer processing module, the capture module and the radar speed measurement module are connected to the computer processing module; the radar speed measurement module includes a microwave The radar module, the signal received by the microwave radar module is transmitted to the signal processing module for processing, the output signal end of the signal processing module is provided with an analog-to-digital conversion module, and the digital signal output by the analog-to-digital conversion module is transmitted to the FPGA control module; the capture module includes There are a panoramic camera and a close-up camera, and the output ends of the data collected by the panoramic camera and the close-up camera are all connected to the video distribution module. The present invention not only organically unifies the radar system and the capture system, but also gives a capture command to the speeding vehicle detected by the radar, ensuring Speeding vehicles have better recognition, and the capture mode has been improved to improve the clarity of the captured video screen.

Description

technical field [0001] The invention relates to the technical field of radar speed measurement and capture, in particular to a radar technology-based intelligent capture integrated device and method for emergency lanes. Background technique [0002] With the steady growth of the national economy, the construction of national infrastructure such as highways in our country is constantly improving, and modern vehicles such as motor vehicles are widely popularized. Concepts such as traffic supervision system, electronic police, and speed radar are gradually becoming familiar to everyone. All kinds of electronic police speeding evidence capture equipment appear on both sides or central isolation belts of expressways, urban elevated roads and expressways, and patrol cars equipped with electronic police speed measuring equipment are also emerging in every corner of the city. However, at present, the speed detection accuracy rate of most speeding forensic capture equipment in China...

AI Technical Summary

Problems solved by technology

[0006] (1) The existing emergency lane capture system uses radar speed measurement to directly roughly display the shape and speed information of the vehicle, and cannot clearly capture and save the video files of the speeding vehicle, resulting in the inability to identify many speeding vehicles in the emergency lane, which is unfair

[0007] (2) The existing express lane capture system only uses the camera capture mode, which wastes a lot of memory, and the proportion of useful data is small. Not only that, the existing video capture system is greatly affected by the weather and the noise of the video itself, and the accuracy unable to meet people's needs
