Embodiment Construction

[0062] The following specific examples further illustrate the present invention, but are not intended to limit the present invention.

[0063] A method for detecting a moving vehicle in front of a smart car, comprising the following steps:

[0064] S1: collect the video image of the road ahead, and preprocess the image, including image clipping, image grayscale, image filtering and image binarization;

[0065] S2: Use the Canny edge operator to enhance the edge information of the road image;

[0066] S3: Use the improved Hough transform method to detect lane lines;

[0067] S4: Segment the shadow of the bottom of the vehicle and perform morphological correction. After correction, only a series of shadow horizontal line segments remain in the image;

[0068] S5: On these shaded horizontal line segments, establish a rectangular frame where vehicles may exist, that is, a region of interest (RIO);

[0069] S6: Based on the fusion of vehicle texture features and vehicle symmetry...

Abstract

The invention discloses a method for intelligently detecting moving vehicles in front of vehicles. The method comprises the following steps of: S1, acquiring a front road video image, and carrying outpreprocessing such as image clipping, image graying, image filtration and image binarization on the image; S2, strengthening road image edge information by adoption of a Canny edge operator; S3, detecting a lane line by adoption of an improved Hough transformation method; S4, segmenting a vehicle bottom shadow, and carrying out morphological correction, wherein only a series of shadow horizontalline areas remain in the corrected image; S5, establishing rectangular frames of possible vehicles, namely, regions of interest (RIO), on shadow horizontal lines; and S6, fusing vehicle texture features and vehicle symmetric features to carry out assumption verification on front vehicles, so as to realize accurate detection of vehicles.

Description

technical field [0001] The invention relates to a detection method for a moving vehicle ahead of a smart car. Background technique [0002] During the driving process of smart cars, due to the complex road environment, we still need to conduct in-depth research on many tasks to make them completely unmanned and autonomous. At present, the intelligent vehicle obstacle detection technology based on machine vision and other related technologies around it are key technologies with rapid development. Whether there is an obstacle in front of the vehicle is detected in real time and accurately, and the success of obstacle detection is directly related to whether the intelligent vehicle can avoid obstacles and drive safely. Research on the obstacle detection technology in front of intelligent vehicles based on machine vision can effectively monitor the surrounding environment of the current driving vehicle in real time, which can reduce the driver's pressure and link fatigue, assis...
