Application of linear array CCD photography technology to railway detecting field

In order to implement the detecting of abrasion of contact wire and rail abrasion for non-contact and dynamic, thenon-contact and dynamic detecting platform with the fast linear array CCD photography technology was developed byscience and technology institute of Shanghai Railway Administration. It was applied to detect the abrasion of contact wire onYing Xia line in Shanghai Railway Administration. On the basis of mentioned background, it was introduced the imagingprocess of linear array CCD sensor and described the principle, mathematic model, equipments collocation, software developmentenvironment, the design of users software to process the single color imaging of linear array CCD for non-contact anddynamic detecting the abrasion of contact wire and rail abrasion.
