A detection method of crack development degree of Asphalt Pavement Based on infrared thermal image analysis is presented. The infrared thermal image of pavement crack is obtained by taking pictures of pavement crack by temperature measuring infrared thermal imager. The relationship model between crack development degree and crack and pavement temperature difference is established. Then the classification function of crack development degree index is learned by machine, and the target of pavement crack can be quickly extracted and processed simultaneously. Classification, effective de-noising of micro-crack signal in noise environment, strong anti-noise ability, low error and false detection rate, suitable for most complex road surface detection.
