In October 2012, a number of media reported that Nissan Motor Co. successfully developed a car auto-avoidance pedestrian system. The system consists of a camera and five laser ranging sensors, which can sense obstacles within 20 meters on the left and right sides of the car, 150 meters in front of the car and 70 meters behind the car. Once the pedestrian suddenly appears in front, the system automatically controls the steering wheel and takes care of it. Actions can not only avoid pedestrians, but also avoid collisions with other vehicles. At present, the automatic brake safety system has been introduced and loaded on some vehicles. The steering wheel control system developed this time can solve the traffic accidents that the brakes can't stop, and the technology is advanced.
Therefore, this article will introduce the laser ranging sensor. The laser ranging sensor is a high-precision distance measuring sensor that uses the laser phase method to measure the distance of objects. Some laser sensors have a response speed of up to 50 Hz. The sensor can measure the distance without a mirror, and the filter can also measure the distance of the high temperature object. It has a wide range of applications, such as container positioning, elevator operation measurement, and electrified railway contact network measurement.
Application field
Hanging XY positioning, container positioning, target distance automatic control, ship safety distance, elevator operation measurement, large workpiece assembly positioning, moving object position monitoring, large object geometry measurement, large shelf inventory management, electrified railway contact network measurement, railway construction The measurement of the boundary of the object and the water level measurement, distance, position, liquid level, material level and production line of the production line of the rivers, lakes and seas.
