Problems solved by technology

The current feature-based lane line recognition mainly performs image segmentation on the road image by analyzing the low-level features of the image. On the actual road, due to factors such as vehicles, shadows, and water marks, the feature-based method interferes with noise such as vehicle occlusion. Insufficient, wh

Embodiment Construction

[0083] In this example, if figure 1 As shown, a distance measurement method based on multi-lane lines is to extract the original image data from the image acquisition device, the characteristics of the image acquisition device itself and the installation position, and extract the features of the lane lines from the original image data collected, and use the obtained two The Hough transform of the valued image is used to obtain the maximum confidence two-lane line and its data. One is to perform parameter optimization and distance measurement; the other is to obtain the maximum confidence two-lane line and its data by using the characteristics of the image acquisition device and its installation. Combining the vanishing line of the position calculation, the position of the vanishing point is determined, and then other lane lines and related information are obtained by using the constraints such as the distance between the lane lines and the position of the vanishing point, for p...

Abstract

The invention discloses a distance measurement method of multiple lanes. The method comprises the following steps: 1, performing lane feature extraction; 2, obtaining a maximum confidence lane and correlation information thereof; 3, obtaining disappearance line correlation information; 4, obtaining disappearance point correlation information; 5, obtaining other lanes and correlation information thereof; and 6, performing curve type lane parameter searching optimization and performing distance measurement work. According to the invention, the multiple lanes can be rapidly and accurately identified, accurate distance measurement is performed, and the method can help an intelligent auxiliary driving system in its control over vehicles.

Description

technical field [0001] The invention belongs to the field of automobile intelligent driving assistance systems, and in particular relates to a multi-lane line detection and ranging method based on improved feature extraction. Background technique [0002] In recent years, my country's automobile industry has maintained a steady development trend. However, while automobiles bring people convenient travel, various traffic accidents remain high. The intelligentization of automobiles has become a research hotspot for researchers. [0003] In the intelligent vehicle driving assistance system, fast and accurate identification of lane lines and accurate distance measurement for lane lines are very important. The current feature-based lane line recognition mainly performs image segmentation on the road image by analyzing the low-level features of the image. On the actual road, due to factors such as vehicles, shadows, and water marks, the feature-based method interferes with noise ...
