Description

technical field [0001] The invention relates to the technical field of unmanned driving, and mainly relates to a traffic signal light recognition device for unmanned driving. Background technique [0002] The current self-driving technology basically has the ability to operate and drive automatically. For example, advanced instruments such as cameras, radar sensors, and laser detectors are installed on the car, and they are used to perceive the speed limit signs and roadside traffic signs on the road, as well as the surrounding environment. The movement of vehicles, people only need to use the map to navigate when they travel. The unmanned driving system mainly uses on-board sensors to perceive the surrounding environment of the vehicle, and controls the steering and speed of the vehicle according to the road, vehicle position and obstacle information obtained by perception, so that the vehicle can drive safely and reliably on the road. [0003] At present, unmanned vehicle...
