Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the following examples are based on the technical solution and provide detailed implementation and specific operation process, but the scope of the present invention is not limited to this implementation example.

[0047] like figure 1 As shown, the vision-aware car forward-looking vehicle and pedestrian anti-collision warning system includes:

[0048] Vehicle front-view area acquisition module: used to collect the video information of the vehicle front-view area and transmit it to the frame acquisition module;

[0049] Frame acquisition module: used to continuously acquire the video information collected by the vehicle front view area acquisition module frame by frame, for detection by the Haar detection module;

[0050] Haar detection module: for adopting the Haar classifier to identify the area where the front vehicle or pedestrian is located...

Abstract

The invention discloses a visual perception-based automobile front-vision vehicle and pedestrian anti-collision warning system and method. According to the visual perception-based automobile front-view vehicle and pedestrian anti-collision warning system and method of the invention, a video acquired by a front-vision camera of a vehicle is read frame by frame; a trained cascade classifier is adopted to recognize vehicles and pedestrians in the video frames; recognition results are filtered by means of straight line detection, so that non-vehicle and non-pedestrian parts can be removed; a deepDBN network is adopted complete the determination of vehicle and pedestrian information in front of the vehicle; after the positions of the vehicles and the pedestrians in front of the vehicle are confirmed, image coordinates are converted into vehicle body coordinates, so that relative distances and relative angles between the vehicle and the vehicles in front of the automobile, and between the vehicle and the pedestrians in front of the vehicle are obtained; a safety time-distance is calculated; a Kalman filter is adopted to predict the positions of the vehicles or pedestrians; and if the distances of the vehicles or pedestrians are smaller than the safety time-distance, an alarm is issued. With the visual perception-based automobile front-view vehicle and pedestrian anti-collision warning system and method of the invention adopted, the vehicles and pedestrians can be recognized more effectively and accurately, and therefore, anti-collision warning can be performed more accurately.

Description

technical field [0001] The invention relates to the technical field of image processing, and in particular to a visual perception vehicle and pedestrian anti-collision warning system and method. Background technique [0002] It is particularly important for a car to recognize cars and pedestrians in its front-sight area in a complex traffic environment. Through the recognition of forward-looking vehicles and pedestrians, it can effectively make up for the lack of the driver's sensory ability, thereby reducing traffic accidents. Therefore, the recognition of forward-looking vehicles and pedestrians when the car is driving has important theoretical and practical significance. [0003] With the advancement of science and technology, vehicle and pedestrian recognition technology has also been developed, but in the actual implementation process, as the scene and shape change, the recognition effect is not satisfactory, and various recognition algorithms only judge and recognize ...
