Abstract

The invention discloses a road traffic sign damage rapid-detection system and a detection method thereof. The system comprises a detection vehicle, wherein a camera, a lighting device, an illuminationsensor, a camera bracket, a phase demodulation device, a quadruplicated frequency device, an industrial computer, a counting device, a data acquisition card, an encoder and a GPS device are mounted on the detection vehicle; the detection method comprises image acquisition, model training, Hough transform and image similarity calculation, and can be used for positioning a damaged traffic sign. Theautomatic traffic sign damage detection method with the detection vehicle greatly reduces the manpower; at the same time, a traffic sign maintenance function is achieved for an area where traffic signs are not regularly detected to reduce the probability of safety hazard caused by traffic sign damage.

Description

technical field [0001] The invention belongs to the technical field of road detection, relates to the detection of road traffic signs, in particular to an express road traffic sign damage detection system and a detection method thereof. Background technique [0002] In recent years, with the rapid economic development, my country's car ownership and the number of drivers have been growing rapidly. The huge number of cars has brought a large number of traffic accidents, and the casualties caused by traffic accidents account for a large part of all safety accident casualties. Among them, the number of safety problems caused by the wrong recognition of traffic signs accounts for a considerable proportion of traffic accidents. It can be seen that the recognition of traffic signs is very important, but the recognition of traffic signs is based on the integrity of traffic signs. When the traffic sign has defects such as cracks, wrinkles, and defects, it brings considerable diffic...
