Abstract

The invention discloses a damage detection system and a detection method for fast road traffic signs. The system includes a detection vehicle, on which a camera, an illumination device, an illumination sensor, a camera bracket, a phase identification device, a quadrupling frequency device, Industrial computer, counting device, data acquisition card, encoder and GPS device; detection methods include image acquisition, model training, Hough transform and image similarity calculation, capable of locating damaged traffic signs. The automatic traffic sign damage detection method combined with the detection vehicle greatly reduces manpower. At the same time, it plays a traffic sign maintenance role in areas where traffic sign detection is not scheduled, reducing the probability of safety hazards caused by traffic sign damage.

Description

Technical field [0001] The present invention belongs to the technical field of road detection, involving traffic signs of roads, particularly related to a fast road traffic sign damage detection system and its detection method. Background technique [0002] In recent years, with the rapid development of the economy, the number of automotive protection and drivers in my country has been growing rapidly. The large number of vehicles brought a large number of traffic accidents, and the casualties brought by traffic accidents accounted for a large part of all safety accidents. Among them, the number of security issues brought about by the traffic sign has considerable proportion in traffic accidents, thereby visible to the identification of the traffic logo is important, but the traffic logo identification is built in the traffic sign. In the case of the case, when the traffic sign, cracks, defects such as cracks, wrinkles, defects, have brought considerable difficulties to the ident...
