Abstract

In this paper we describe three dimensional (3D) reconstruction of irregular object lack of texture based on structured light techniques. This system uses a CCD camera synchronized with the DLP projector captures the images, from which the 3D shape of the object is reconstructed. With the characteristic of the right image obtained from the projector and collinearity equations, the spacial point coordinates on the surface of the irregular object are obtained quickly by space intersection. As the grid table is rotating, the projector and the CCD camera are always fixed. Then all the point coordinates of different surfaces are computed in the same reference frame while the interior and exterior orientation elements of the CCD camera and projector are obtained in each different point of view. A CCD camera is also used to capture images for texture mapping. The untouched method based on close-range photogrammetry can be successfully adapted to reconstruct various kinds of shapes and some soft objects in the diverse areas.
