A Study on the Measurement of an Object with Grid Pattern
격자 무늬를 지닌 3차원 물체의 측정에 관한 연구
Abstract
From the relationship between the two different views of an object with grid, the three dimensional coordinates of intersection points are determined. The images are captured and digitized with a CCD camera and a frame grabber. To find intersection points, local thresholding and line thinning operations are performed. By establishing the correspondence between the points in the two views, the three dimensional corrdinates of intersection points are calculated.
