Embodiment Construction

[0059] The implementation method and principle of the present invention will be further described below in conjunction with examples and accompanying drawings.

[0060] An ADAS system based on image processing, including a front-view camera installed on the vehicle, acquires images through the camera, and then performs the following processing:

[0061] 1. Preprocessing the image:

[0062] Color image grayscale, intercept effective information area, filtering and denoising, image grayscale enhancement, edge detection and repair of lane lines. After edge detection, the edges of lane lines are intermittent and not continuous, and need to be repaired. The processing step is to first find the "short line segment" we need, and process each white point. If there are 4 consecutive white points in a certain direction, it is judged as a "short line segment", and all the "short line segments" are found. segment” and record its direction. The second step is to search for each short lin...

Abstract

The invention discloses an image-processing-based ADAS (advanced driver assistance system) which uses a front view camera installed on a vehicle to acquire images and processes the dynamic images in real time so as to send out a warning if a driver is unconsciously off a lane. Compared with traditional ADASs, the image-processing-based ADAS has the advantages that the system has good applicability and can recognize lanes at night, on rainy days and in tunnels; an algorithm is simple and takes short time, and the timeliness requirement can be met; the system has small detection errors and high precision.

Description

[0001] Technical field: the present invention relates to smart car technology, especially a kind of car advanced driving assistance system. technical background: [0002] With the progress of society, the improvement of people's living standards and the development of transportation tools, the number of cars in the world has increased dramatically. At the same time, traffic safety issues have also become a hot issue of global concern. Advanced Driver Assistance Systems (ADAS) have emerged and have been widely used. focus on. ADAS uses various sensors to obtain information inside and outside the vehicle, and after various processing, it finally alerts the driver to possible dangers that may occur in order to reduce the incidence of traffic accidents. [0003] Due to the limited level of image recognition processing in the actual use of existing ADAS, problems such as false positives and false positives often occur, and it is difficult to have long-term long-distance stable oper...
