Abstract

The invention provides a pavement pit detecting method based on vehicular binocular vision. The method singles out a pavement pit by selecting a reasonable threshold of vibration sampling information of a vibration sensor, gives positional information of the pavement pit in combination with GPS information, and records GPS information by using a key manual external trigging device when wheels run over the pavement pit. A binocular camera system samples a tested pavement and outputs an image to a computer. After acquiring the image of the pavement pit, the computer performs preprocessing and an image processing algorithm on the image so as to obtain the area and depth information of the pavement pit. The method may position the pavement pit, optimizes the conventional image processing algorithm, and may accurately achieve a pavement pit area and depth computing function.

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...
