US Patent 11915492 Traffic light recognition method and apparatus

This application discloses a traffic light recognition method and apparatus in the field of artificial intelligence that relate to an automated driving technology. The recognition apparatus determines location information of n first traffic lights in a first image based on current positioning information of a vehicle, a calibration parameter of an image sensor, and prestored map data; and detects the first image by using an image detection method, to obtain location information of m second traffic lights in the first image and indication information of the m second traffic lights. This effectively reduces a traffic light recognition error, and improves recognition accuracy.
