Uber has given up on the Chinese market, and the news about it seems to be only unmanned. Not long ago, another friend on Instagram uploaded a photo of the Uber unmanned vehicle on the San Francisco road. You know, California is the most regulated state in the United States, and can get the road test license in California. It seems that the Uber unmanned car is doing a good job now.
The picture above is a photo of the Uber unmanned vehicle on Instagram, and the device like a flower pot on the roof is a laser radar, which is also the "eye" of the unmanned vehicle. The unmanned vehicle can receive the road condition information, mainly relying on its function.
A laser radar is a radar system that emits a laser beam to detect the position, velocity, and material of a target. We can divide the lidar core device into three parts, the laser emitter, the optical scanning and receiving components, and the photosensitive components.
Lidar working diagram
Through the pattern in the above figure, the laser radar relies on the laser's return time after the obstacle, and can calculate the distance and generate the 3D contour of the object, and draw a map of the surrounding environment of the car. Lidars are highly accurate and can even reach centimeters.
This site has made an inventory of laser radar technology related companies at home and abroad.
Representative laser radar related companies abroad
The picture above shows five representative Lidar companies in foreign countries, three of which are American companies. The technical applications of the five companies are all driverless cars.
Domestic laser radar related company inventory
The above picture shows the inventory of domestic lidar-related companies, including 10 companies. Among these companies, there are three in Beijing and Shenzhen, each accounting for 30% of the total, and two others are located in Shanghai.
Unlike foreign companies, more companies are focusing on the field of home robots. There are 6 companies that develop laser radar for robots, accounting for 60% of the total. There are 5 companies that use unmanned vehicles.
The application direction of laser radar at home and abroad is related to the development time and progress. It started early in the country, so it also occupied the breakthrough of driverless cars in the first time. The development of domestic laser radar is late, and the precipitation on hardware and software is insufficient. Most of them use service robots as a new entry point.
