Abstract

The invention discloses a vehicle identification method and device and a vehicle. The method comprises the steps that a first image and a second image are acquired, the first image is a color image or a brightness image, and the second image is a depth image; road lane lines are acquired according to the first image; the road lane lines are mapped to the second image according to the interleaving mapping relation between the first image and the second image so that a vehicle identification range is generated in the second image; and the vehicle is identified according to the vehicle identification range. According to the method, the opposite-side vehicle can be rapidly and high-precisely identified, and alarm information can be rapidly and reliably generated on the basis of the identified opposite-side vehicle so that valuable braking reaction time can be won for the driver of the vehicle or the opposite-side vehicle and thus driving safety can be further enhanced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle identification method, device and vehicle. Background technique [0002] In modern traffic, expressway traffic has become an indispensable traffic mode due to its fast speed, many lines, and large passenger flow. However, due to the characteristics of expressway traffic, the frequency of expressway traffic accidents remains high, and casualties and property losses are often very serious. Therefore, vehicle identification technologies for vehicle driving safety continue to emerge, including millimeter-wave radar and lidar technology. [0003] However, the production cost of millimeter-wave radar and lidar has not been effectively reduced, and they have become exclusive products for luxury cars in the field of passenger cars. Therefore, it is disclosed in the related art to use a single ordinary low-cost camera or an infrared camera to image the vehicle in front or beh...
