Vehicle-mounted surface unevenness monitoring method based on multiple sets of laser lines

Abstract

The present invention discloses a vehicle-mounted surface unevenness monitoring method based on multiple sets of laser lines. A monitoring device includes laser line emitters, an imaging device, an image acquisition device, an information processing device and a road condition warning device. The imaging device is responsible for the real-time monitoring of an image formed by laser line signals emitted by the laser line emitters on a road surface to obtain a road surface image signal. The image acquisition device reads the road surface image signal and converts the signal into a digital signal, then transmits the signal to the information processing device to carry out analysis calculation, a road surface pit depth or raised height is obtained and is compared with a vehicle minimum groundclearance h, and a driver is timely notified through the road condition warning device when passing requirements are not satisfied. The method has the advantages of a simple and convenient algorithm and a reliable conclusion, the real-time monitoring of road surface unevenness is facilitated and is timely delivered to the driver, and the driving safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of road surface passability monitoring and safe driving, and in particular relates to a vehicle-mounted road surface unevenness monitoring method based on multiple sets of laser lines. Background technique [0002] Urban roads are easy to be damaged. Due to the problems of roadbed and materials during construction, as well as the influence of bad weather, heavy vehicles stay on the road for a long time, and the road surface is easily damaged, with pits, bumps, cracks and other problems. Poor road smoothness will affect the comfort of the car, reduce the speed of the car, accelerate the wear and tear of vehicle parts, and increase the operating cost of the vehicle. When the road surface is severely depressed, the chassis of the car is likely to hit the ground heavily, causing a car accident. Especially when driving at night, the road visibility is poor, and accidents are more likely to occur on roads with po...

AI Technical Summary

Problems solved by technology

Poor road smoothness will affect the comfort of the car, reduce the speed of the car, accelerate the wear of the vehicle parts, and increase the operating cost of the vehicle

When the road surface is severely depressed, the chassis of the car is likely to hit the ground heavily, causing a car accident

Especially when driving at night, the road visibility is poor, and accidents are more likely to occur on roads with poor passability

In traditional cars, the driver often only relies on the driver to observe the road conditions, and it is often impossible to observe the pits and bumps on the road in time, let alone know whether the road ahead meets the passability requirements
