Requirements of Sensors in Lidar System

Update: 2019-10-12 17:15 Source: LUFTMY

The lidar system is a basic component of the automobile, which relies less and less on the driver's active control. In this paper, we summarize the functions of such systems and the special functions of sensors.

Lidar (light detection and ranging) technology constitutes an effective driver assistance system, such as adaptive cruise control, collision warning system, lane change assistant and blind spot alarm. Even if lidar is related to radar, it uses laser beams instead of radio waves to measure speed and distance. With its high angle and range resolution, lidar system replaces traditional radar and camera systems. With software, very accurate models of the area around the vehicle can be created. This can not only detect road users (such as vehicles and pedestrians), but also provide information about road signs, signs and other transportation facilities (such as obstacles or traffic lights).

Requirements to be met by lidar system

1. Surveillance of surrounding areas: High-speed vehicles in particular need a very broad "horizon", as effective a prediction system as possible and a very fast and reliable detection system.

2. Resistance: The sensor used must be able to withstand various environmental impacts, all weather conditions and wind speed.

3. Compliance: Electronic systems must naturally meet the usual industry requirements, and the sensors used must be suitable for the overall design of the sensor system used.

4.Cost efficiency: People who develop lidar systems need to pay attention to cost and find a solution that is 100% reliable and cost-effective.

Which system meets the requirements of maximum security and flexibility? For high-speed vehicles, the remote lidar system can detect objects up to 300 meters away, which is the most consistent laser.

How to Choose the Best Sensor

Sensors are the core of any lidar system. Each sensor technology has its own advantages and disadvantages. Without lidar, no driver assistance system can survive. Sensors, in turn, play a major hidden role in this technology. Without them, automatic driving would be unthinkable. If the laser beam is not used, the distance and velocity of the object can not be measured safely.

Guangzhou LUFTMY s7-l Smart Dust sensor can accurately detect the number and concentration of particles in the ventilation duct of the vacuum cleaner through the handle or extension rod pipe, sweeping robot, range hood, particle detection instrument and other equipment with the principle of optical injection. The vacuum cleaning effect of the equipment and the cleanliness of the floor, carpet, bed sheet, etc. are presented to the user visually through the output data of the sensor and LED color display.
