The invention relates to a lane turning information identification method based on a traffic label and a ground sign. The method comprises the following steps of 1, acquiring image sequence data of an actual road by means of movable measuring vehicle; 2, performing traffic label detection and identification on each image for obtaining steering information of the traffic label in the lane; 3, performing ground sign detection and identification on each image for obtaining steering information of the ground sign in the lane; 4, performing image sequence analysis on the steering information identification result of the step 2 and the step 3, respectively calculating reliabilities of the traffic labels and reliabilities of the steering information of the ground sign, and using the traffic label with highest reliability and the steering information with highest reliability as respective identification results; and 5, comparing a traffic label identification result in the lane with a ground sign identification result, and obtaining steering information of the lane segment. According to the lane turning information identification method, through analyzing the distribution characteristic of the ground signs and the traffic labels in the actual rod, and utilizing a mutual confirming mechanism, high-accuracy identification for the steering information of the lane is realized.
