Research on Automatic Detection System Based on Full face Pavement Crack Digital Image

Automatic detection system has been widely used in pavement detection. This paper describes the principle of shooting width adjustment and method of adjusting the width of the image acquisition. This system increased width of pavement video acquisition system from maximum width of 5 meters at present to full face pavement 12 meters.It is proved through testing sections that it achieved good image effect and met the design requirements.
