Problems solved by technology

However, the actual road conditions are complex and diverse, and the use of lane line features to identify lanes is prone to environmental interference, such as weather, shadows, etc., resulting in poor recognition results
When the lane position information cannot be accurately detected, the smart car may not be able to drive automatically, and more seriously, it may lead to dangerous accidents

Embodiment approach

[0083] According to an embodiment of the present disclosure, one of the implementation manners is: first obtain the light intensity information of the area where the vehicle is driving, and then determine the road edge features obtained by processing the image information and the road edge features obtained by processing the image information according to the light intensity information. The weight ratio of the road edge features obtained from the above radar information.

[0084] In this embodiment, since the camera is easily affected by the light intensity when collecting image information, when the light intensity is too low, it means that the light in the environment is dark, and the camera cannot obtain a clear image; and when the light intensity is too high, the exposure of the image A higher degree may lead to inaccurate lane recognition results. The radar is not greatly affected by the intensity of light. When the weather is good, the detection accuracy of the radar is...

Abstract

The embodiment of the invention discloses a lane recognition system and method and an autonomous car. The lane recognition system comprises at least one camera, at least one radar, a data processing unit and a lane recognition unit. The lane recognition unit is connected with the data processing unit and is used for confirming the weight proportion of the road edge features obtained by processingimage information to the road edge features obtained by processing radar information, and the lane position is recognized according to the weight proportion, the road edge features obtained by processing the image information, the road edge features obtained by processing the radar information and lane line features. According to the technical scheme, data fusion of camera and radar equipment on lane recognition is achieved, and therefore the system can handle with complex road conditions and environment interference better, dangerous accidents are avoided, and driving safety is improved.

Description

technical field [0001] The present disclosure relates to the technical field of automatic driving, in particular to a lane recognition system and method and an automatic driving vehicle. Background technique [0002] With the development of automobile intelligent technology, smart cars can realize automatic driving. In order to be able to accurately drive according to the navigation path, the smart car obtains the lane position information according to the installed camera or radar equipment. [0003] In the process of proposing the present disclosure, the inventors found that the lane position recognition in the prior art adopts the lane line detection method based on road features, which utilizes the physical feature difference between the lane line and the road environment for subsequent image segmentation and processing , so as to highlight the characteristics of the lane line to realize the recognition of the lane position. However, the actual road conditions are comp...
