The Application of Digital Image Processing Method in Range Finding by Camera

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