Lidar is a comprehensive light detection and measurement system. Compared with ordinary radars, lidars can provide high-resolution geometric images of radiation intensity, distance images, and speed images. At the beginning, they were mainly used in the military field. And now this laser pointer technology has gradually penetrated into the consumer market. Especially in the field of unmanned driving, as Google, Baidu, Ford, Audi, BMW and other companies have successively adopted lidar sensing solutions, lidar has become the "standard" for researching unmanned technology.
At present, lidar can be divided into mechanical scanning lidar and solid state lidar. Lidar can be divided into 2D, 2.5D (1, 4, 8 lines) and 3D (16, 32, 64 lines) products according to the number of lines.
At present, the application of lidar in unmanned driving technology is to 3D model the surrounding environment of the vehicle, obtain the depth information of the environment, identify obstacles, and build a drivable area. With the further popularization and application of driverless technology, driving the development of the driverless industry chain, lidar has clearly benefited as a mainstream sensor in driverless.
As one of the most important sensors in driverless technology, vehicle lidar is of great significance for ensuring the driving safety of driverless cars. With the further development of the driverless industry, the automotive laser pointer radar market has a bright future. According to the data from the "Forecast and Investment Strategic Planning Analysis Report of the Lidar Industry Market" released by the Foresight Industry Research Institute, the vehicle lidar market in China in 2015 was 109 million yuan, and the market size in 2016 was 193 million yuan, a year-on-year The increase was 77.06%. With the gradual popularization of driverless cars, the on-board lidar market in China will maintain a rapid growth. It is estimated that by 2021, the on-board lidar market in China will exceed 600 million yuan. In the future, the advent of industrialization of driverless cars and the reduction of on-board lidar costs will jointly promote the explosive growth of the on-board lidar industry.
