| Abstract: | It is indispensable to detect the position of controlled feature-point in an image accurately when CCD-based non-contact 3D measurement is carried out. Practical method of image processing and analysing, which is utilized for the measurement of a certain model of aerospace product, is presented in this paper. Three different methods used to detect the position of a feature-point in an image are presented and compared with each other. A pratical processing result is presented at the end of the paper. |
