Machine vision was first applied in industrial manufacturing field, and now it is also used in road detection, with the rapid development and continuous innovation of computer technology and digital image processing technology. This study provides a detailed description of the application of machine vision technology in detection of pavement crack, such as crack image acquisition, preprocessing (image de-noising and enhancement), segmentation, and recognition technology. Further the application of machine vision technology in pavement compactness and evenness was introduced. Finally, based on the application of machine vision in other aspects of road detection, hopefully, this study can provide a reference for method of road detection.
