Embodiment Construction

[0054] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0055] Such as figure 1 As shown, a zebra crossing detection method for assisting the safe driving of a vehicle includes:

[0056] S1. The target scene is photographed by a vehicle-mounted camera to obtain a road image in the target scene. The road image includes a region of interest that includes the target to be detected and a non-interest region that does not include the target to be detected, and the target to be detected is a zebra crossing;

[0057] S2. Perform a line feature detection on the road image to obtain the line feature;

[0058] S3. Obtain the position information of the vanishing point in the road image according to the line feature;

[0059] S4. Perform secondary line feature detection on the road image to obtain...

Abstract

The invention discloses a zebra crossing detection method and system for assisting safe driving of a vehicle. The method includes: S1, shooting a target scene by a vehicle-mounted camera, and acquiring a road image in the target scene; S2, performing line feature detection on the road image to obtain Line feature; S3, obtain the position information of the vanishing point according to the line feature; S4, carry out secondary line feature detection to the road image, obtain the straight line feature in the road image; S5, black and white the line feature in the road image mark, and obtain all line segment information; S6, perform a screening on the line segments in the road image to obtain candidate ROIs; S7, perform secondary screening on candidate ROIs, and obtain the final detection result. The beneficial effect of the invention is that not only a single target can be detected, but also multiple targets to be detected under complex intersections can be detected.

Description

Technical field [0001] The invention relates to the technical field of target detection, in particular to a zebra crossing detection method and system for assisting safe driving of vehicles. Background technique [0002] With the development of society and economy, people have paid more and more attention to traffic problems. Urban road intersections have concentrated traffic and people from all directions. They are at the core of the urban road network and are also a place with a high incidence of traffic accidents. . Road intersections are very important traffic areas today. According to statistics, when vehicles are driving on urban roads, an average of 30% of their time is spent on road intersections, and 64% of traffic accidents occur at road intersections. Road zebra crossing is an important safety sign. It is the traffic sign information that must be recognized in the safe driving system based on visual recognition. For vehicle drivers, zebra crossing means driving carefu...
