Application of laser radar filter in unmanned driving

Driverless car is an intelligent car that senses the road environment through the on-board sensing system, automatically plans the driving route and controls the vehicle to reach the predetermined target. Lidar is one of the most commonly used environmental sensing technologies in unmanned technology, which transmits laser beams and receives their reflected signals to identify and measure information such as distance, position and shape of surrounding objects.

Lidar filters play an important role in unmanned driving. LIDAR is a type of sensor that uses a laser beam to measure distance and obtain information about the environment. Lidar systems typically consist of a laser transmitter and receiver capable of detecting objects, obstacles and terrain in the surrounding environment. A LiDAR filter is an optical element used to adjust the spectral characteristics of a liDAR system. Here are some common uses for LiDAR filters in unmanned driving:

Wavelength selection

Lidar filters can select specific laser wavelengths to suit different environments and applications. Specific wavelengths of laser light can reflect or penetrate better on specific materials, thus improving detection performance.

Environmental inhibition

By using filters, the sensitivity of liDAR systems to specific environmental conditions can be reduced. For example, some filters can reduce reflection and scattering in rain and snow weather, improving the stability of lidar in bad weather conditions.

Multi-sensor integration

By using filters, the sensitivity of liDAR systems to specific environmental conditions can be reduced. For example, some filters can reduce reflection and scattering in rain and snow weather, improving the stability of lidar in bad weather conditions.

Reduce interference

Filters can also be used to reduce interference from external light sources in liDAR systems, thereby improving the accuracy and reliability of the system.

Overall, lidar filters are an important technical component in driverless technology, helping to optimize sensor performance and improve vehicle perception, thereby enhancing driving safety and the efficiency of autonomous driving systems.
