Abstract

The invention discloses a safety belt detecting method based on Hough transform, relating to the field of intelligent transportation. In the safety belt detecting method based on the Hough transform, two parallel straight lines on the edge of a safety belt are detected through the Hough transform of cumulative probability, and whether a driver and passengers wear the safety belts is determined by a geometrical way of shoulder and waist diagonal crossing of the safety belts. The safety belt detecting method based on the Hough transform comprises the following steps: extracting the edge of the safety belt; and performing straight line detection based on the Hough transform. Compared with other detection method, the safety belt detecting method based on the Hough transform has the advantages as follows: the detection rate of not wearing the safety belt is improved; for a motor vehicle picture with nonuniform illumination, the detection rate of not wearing the safety belt is improved; a detection scheme based on the Hough transform is provided for safety belt detection in an intelligent transportation system; the real-time performance is high; and the intelligent transportation system is easier to install and easy to maintain.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a safety belt detection method based on Hough transformation. Background technique [0002] In the field of intelligent transportation, the detection method of seat belt is rarely mentioned; but whether wearing a seat belt or not is closely related to the safety of drivers and passengers, so in order to create a greater security environment for a peaceful and harmonious society, intelligent transportation based on image processing Seat belt testing methods have only recently emerged. [0003] Seat belt detection has the following problems: [0004] 1. Extract the feature vector of the seat belt and use the classifier trained by SVM (Support Vector Machine) to be less applicable to the detection of all window seat belts; [0005] 2. For the window picture with uneven illumination, the edge extraction is too dense, and the edge of the seat belt is diluted by the edge of ...
