Embodiment Construction
[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0051] Such as figure 1 As shown, a method for detecting the fastening state of a car seat belt based on road monitoring equipment, based on images taken from the road, includes the following steps:
[0052] Step 1: Obtain monitoring images from road monitoring equipment, such as figure 2 shown;
[0053] Step 2: After preprocessing the monitoring image according to the characteristics of the car and the background object, use integral projection to locate the body area in the original monitoring image obtained in step 1, such as image 3 shown;
[0054] The preprocessing sequentially includes image grayscale, image filtering, edge detection and background noise removal operations;
[0055]Step 3: Use hough transform to locate the window area from the body area, such as Figure 4 shown;
[0056] Step 4: Locate the steering wheel...
