The invention is a road surface pothole detection method based on vehicle-mounted binocular vision. The detection method uses the vibration sampling information of the vibration sensor to take a reasonable threshold to screen out the road surface potholes, and combines GPS information to provide the location information of the road surface potholes. When the wheel leaks pressure on the road surface potholes, the GPS information at that time can be recorded through the button-type manual external trigger device. The binocular camera system samples the test road surface and outputs it to the computer. The processing algorithm obtains the area and depth information of road potholes. By adopting the technical scheme of the invention, not only can the location of the road pothole be completed, but also the traditional image processing algorithm is optimized in terms of algorithm, and the functions of calculating the area and depth of the road pothole can be accurately realized.
Description
technical field [0001] The invention relates to the field of road detection and image processing, in particular to a detection method for measuring the position, area and depth information of road potholes based on binocular vision and using an image processing algorithm. Background technique [0002] In recent years, economic development has led to an increase in the number of vehicles. With the accumulated wear and tear of the road surface, the appearance of potholes is inevitable. Therefore, the importance of road pothole detection for vehicle driving is self-evident. Pothole inspection is an important part of pavement quality inspection. The development of digital image processing technology makes traditional pavement inspection work more intelligent and mechanized. [0003] However, pavement potholes are a special form of pavement damage. Traditional road surface measurement methods, such as bump accumulators and laser rangefinders, can only obtain the curve of the long...
