ABSTRACT

For the disadvantage of contact method in range finding, such as physical effects, high requirements of environment, operating errors and so on, a different method is proposed as required--digital image processing for range finding. This non-contact method could be finished after the collection and handling of laser spots by USB camera, the extraction of feature information of image, and the building of the Quantitative relationship between feature and measured displacement. It is available and practical by experiment without the complex marking procession of camera system.
