It can achieve a wider range of intelligent driving with a simpler hardware system, bringing users a richer, freer, and full-scenario driving experience. .
GAC’s pure visual intelligent driving without images The driving system has three leading capabilities in visual recognition, giving it significant advantages in the field of autonomous driving. First, the ability to understand complex traffic roads with extreme precision. Whether it is ramps, tunnels, curves or complex scenes such as intersections and bifurcated roads, this system can accurately identify and understand the structure of the road. Secondly, super traffic light recognition ability. This system uses a deep neural network to achieve accurate identification of various signal light elements, including signal light types, various symbols and colors, countdowns, and flashing states. Third, the ability to handle complex and changeable scenarios. The sensing range of this system reaches 150 meters in front of the car, 100 meters behind the car, and 50 meters left and right, which is 1.5 times the industry level.
