Problems solved by technology

[0003] The types of traffic lights that can be recognized by the current traffic light recognition method are not comprehensive enough, and the accuracy of recognition cannot meet the needs of users. The main reason is that the existing sensor technology and the limitations of the camera itself make the recognition of traffic lights flawed.

Embodiment Construction

[0062] Specific embodiments of the present disclosure 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 disclosure, and are not intended to limit the present disclosure.

[0063] In related technologies, the types of traffic lights that can be identified by the traffic light recognition method are not comprehensive enough, and the accuracy of recognition cannot meet the needs of users. The main reason is that the existing sensor technology and the limitations of the camera itself make the traffic light recognition Flawed.

[0064]To solve this technical problem, this disclosure proposes a method for identifying traffic lights using an image acquisition device composed of a single camera and a TOF (Chinese: Time of Flight; English: Time of Flight) sensor. Among them, the time-of-flight sensor refers to an array or collection of...

Abstract

The present disclosure provides a method, device and vehicle for identifying traffic lights. The method uses an image acquisition device composed of a single camera and a TOF sensor to acquire images. For the same shooting area, a color image is obtained by a single camera, and a depth image is obtained by a time-of-flight sensor. A single camera is usually used to obtain color or brightness information of a color image, and does not have the ability to obtain the distance between the object being photographed and the camera. In the present disclosure, a time-of-flight sensor is combined to obtain a depth image, and a detection method based on road markings is used to identify traffic lights, so that the identification results of traffic lights are more accurate.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a method, device and vehicle for identifying traffic lights. Background technique [0002] With the rapid development of social economy, vehicles are becoming more and more popular, but at the same time, the incidence of traffic accidents is also increasing. In order to avoid the occurrence of traffic accidents, more and more attention has been paid to the intelligent transportation system, and the identification of traffic lights is an important aspect of the intelligent transportation system. [0003] The types of traffic lights that can be recognized by the current traffic light recognition method are not comprehensive enough, and the accuracy of recognition cannot meet the needs of users. The main reason is that the existing sensor technology and the limitations of the camera itself make the recognition of traffic lights flawed. Contents of the invent...
