Problems solved by technology
[0004] However, in practical applications, when there are multiple target vehicles on the side and rear of the subject vehicle, due to the working principle of the radar, it may not be possible to well identify the lane in which each target vehicle is located, which may lead to a distance of one or more distances from the subject vehicle. Target vehicles in multiple lanes are incorrectly identified as threatening vehicles
Therefore, a radar-only host vehicle would likely alert the driver excessively and unnecessarily, distracting the driver

Embodiment Construction
[0063] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0064] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the contextual objects are an "or" relationship.
[0065] figure 1 is a flow chart of a vehicle identification method shown according to an exemplary embodiment, such as figure 1 As shown, the vehicle identification method can be applied to a subject vehicle, and includes the f...

The invention discloses a vehicle identification method, device and vehicle, which are used to improve the accuracy of identifying a target vehicle. The method includes: acquiring a first image and a second image, wherein the first image is a color image or a brightness image, and the second image is a depth image; according to the first image, identifying All highway lane lines; according to the mapping relationship between the first image and the second image, map the highway lane lines to the second image, so as to determine at least one vehicle identification in the second image Range, wherein, every two adjacent road lane lines create a vehicle identification range; each vehicle identification range in the at least one vehicle identification range is marked as the rear lane, the Nth lane on the left, or the Mth lane on the right Lane, N and M are both positive integers; identify the target vehicle in the at least one vehicle identification range.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle identification method, a device and a vehicle. Background technique [0002] With the continuous development of science and technology, people's travel is becoming more and more convenient. Various cars, electric vehicles, etc. have become an indispensable means of transportation in people's lives. However, although these means of transportation facilitate people's travel, traffic safety accidents do occur frequently. In order to improve the safety of vehicles, ranging sensors can be installed on vehicles to sense multiple target vehicles around the vehicle to reduce collisions. accident rate. [0003] At present, stereo cameras or more than two radars can be used as ranging sensors. By installing these types of ranging sensors, the subject vehicle can sense multiple target vehicles at the rear or side of the subject vehicle at the same time, and can sense When a thr...
