Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0045] A kind of night vehicle identification method provided by the present invention, such as figure 1 shown, including the following steps:

[0046] 1) Place the camera on the rearview mirror to obtain the video stream during the driving process of the car, extract each frame of the video stream to obtain the corresponding picture, the selected video should reflect the complex working conditions of the vehicle at night, and the video duration should be at least 2 hours;

[0047] 2) Divide the above pictures into regions, establish several region lists, and extract ROI regions of interest; divide the regions according to the ratio of dividing the 720 resolution image into 80×80 size;

[0048] 3) Process the obtained area of ​​interest, first perform YUV space extraction, Y ...

Abstract

The invention discloses a night vehicle identification method which comprises the following steps: 1) placing a camera on a rearview mirror, obtaining a video stream in the driving process of an automobile, and extracting each frame of the video stream to obtain a corresponding picture; 2) carrying out region division on the picture, establishing a plurality of region lists, and extracting ROI regions of interest; 3) processing the obtained region of interest; 4) setting a threshold value through the image filtered by the YUV; (5) processing an obtained image by opening operation, firstly performing corroding operation, then carrying out expanding operation; 6) performing Gaussian filtering; 7) finally, performing edge detection; 8) after the above processing of the car taillights, finallypairing the lights to complete the night vehicle detection. The invention solves the problem that a conventional night vehicle detection method is low in efficiency and accuracy.

Description

technical field [0001] The invention relates to the technical field of vehicle identification, in particular to a method for vehicle identification at night. Background technique [0002] Nighttime vehicle detection is to use computer vision technology to judge whether there is a car in an image or video sequence and give precise positioning. This technology can be combined with pedestrian tracking, pedestrian re-identification and other technologies to be applied in night artificial intelligence systems, vehicle assisted driving systems, intelligent robots, intelligent video surveillance, human behavior analysis, intelligent transportation and other fields. [0003] The current night vehicle detection algorithm is mainly as follows: [0004] 1. Night vehicle detection based solely on HSV [0005] HSV refers to Hue (hue), Saturation (saturation) and Value (value). The hue H is measured by angle, and the saturation S indicates the degree to which the color is close to the s...
