Abstract

The invention discloses a lane line detection method and device based on morphological reconstruction. The lane line detection method includes the following steps: de-noising a region of interest of ato-be-detected road image through morphological reconstruction, and obtaining a processing result; extracting lane line features in the processing result, and acquiring a binary image of the lane line features; processing and making a Blob analysis of the binary image to confirm the lane line image blocks of the to-be-detected road image. According to the invention, the to-be-detected road imageis preprocessed to remove the black and white noise in the to-be-detected road image, so that the algorithm process of road lane line detection is more simple and efficient, and fast lane line detection is realized.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a lane line detection method and device based on morphological reconstruction. Background technique [0002] The lane departure warning system and the lane keeping system are two important functional modules of the advanced driver assistance system, the core technology of which is the lane line detection algorithm. With the vigorous development of unmanned driving technology and advanced driver assistance systems, more and more lane line detection algorithms have emerged. Due to the inherent imaging characteristics of the camera and the influence of external ambient light, the appearance of noise on the collected images is also different. It is necessary to preprocess the image to remove the influence of noise on lane line detection. Preprocessing is a very important link. However, the traditional lane line detection algorithm does not pay enough attention to th...
