Application of Laser Range Finder in Car Collision Avoidance Detection, Traffic Flow Monitoring and Drone Control

1. Car anti-collision detection

Most existing automotive collision prevention systems use laser ranging sensors that use laser beams to identify separation between cars without contact.

When the distance between the cars is less than the predetermined safe interval, the car anti-collision system can emergency brake the car, or send an alarm or comprehensive data to the driver. The timely judgment and response time of the car while driving can greatly reduce driving accidents. Laser ranging The advantages of sensors on highways are becoming more and more obvious.

2. Traffic flow monitoring

The method of use is generally fixed on a gantry on a highway or an important

intersection. The laser emits and receives vertical air downwards and is aimed at the middle position of the lane. When a vehicle passes, the Laser Ranging Sensor can output the relative change value of the measured interval value in real time. , thereby depicting the measured vehicle profile. This measurement method generally uses a ranging range, and the laser ranging speed requires high speed. Monitoring on important road sections can identify various vehicle types, and the sampling rate of body height scanning is high. The height and length limits of traffic flow and vehicleclassification can be recognized in real time and the results can be output quickly.

3. Drone control

New concept systems such as autonomous driving technology stimulate the need for ranging and obstacle avoidance technologies. In these technologies, ranging is the basis for obstacle avoidance, and there are a variety of technologies to complete ranging, including radio frequency, ultrasonic, infrared and laser. Laser etc. The ranging module has a built-in drone, which can identify the height to the ground and the distance to obstacles or targets in real time to adjust the drone's attitude and flight speed in real time.

Meskernel have mainly focused on the field of laser measurement and control, Laser Ranging Module, Laser Distance Sensor, Laser Rangefinder Module as long as Laser Distance Meter, Laser Rang Finder and 2D 3D LiDAR.
