Characteristics and application scenarios of non-contact laser speedometer for motor vehicles
Non-contact laser speedometer for motor vehicles is a new type of laser speedometer based on distance measurement, which is installed directly above the lane; it is mostly used for speed detection of high-speed moving objects. Compared with traditional radar, it has high accuracy and strong anti-interference ability, such as tunnel vehicles. Detection
Characteristics of non-contact laser speedometer for motor vehicles:
The use of 4 laser beams in a single lane solves the problem that the speed detection laser detection range is too narrow in the past, and fully realizes full lane coverage;
It is based on the detection time difference between the two groups of laser beams before and after, to measure the accurate driving speed of the motor vehicle. At the same time, by measuring the height of the vehicle, the vehicle type to be tested can be output.
Adopt high-frequency pulsed laser to ensure the extremely fast response speed, which solves the problem of drift of the capture position that often occurs in radar speedometers. Can also capture the illegal behavior of ultra-high-speed vehicles.
The built-in narrow-band optical filter can filter all light waves except the emitted light, effectively removing strong light interference such as sunlight and vehicle headlights. And through advanced signal processing algorithms, it can also work normally under severe weather conditions such as rain, snow, fog, and haze.
