Claim 0:
1. A traffic light recognition method, comprising:
obtaining current positioning information of a vehicle and a first image, wherein the first image is currently obtained by using an image sensor;
determining location information of n first traffic lights in the first image based on the current positioning information of the vehicle, a calibration parameter of the image sensor, and prestored map data, wherein n is an integer greater than or equal to 1;
detecting 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, wherein the indication information comprises at least one of a color and semantic indication information, and m is an integer greater than or equal to 1;
determining, based on the location information of the n first traffic lights in the first image and the location information of the m second traffic lights in the first image and based on a preset error constraint, a first traffic light and a second traffic light that match each other; and
obtaining indication information of the second traffic light that matches the first traffic light.
