摘要：The paper proposed an approach to reconstruct the solid of rotation lacking in texture from two-dimensional images. The approach only requires a digital camera, an ordinary slide projector and a rotated platform. The camera and projector are required to be calibrated in advance. The rotated platform is functioned as a control ground and the target object is put on it. The projector projects the slide points onto the solid of rotation so that the texture is supplied to the surface of it. The digital camera takes sequential images with these points when the platform rotates continually. For each space feature point projected on the surface of the solid of rotation, there are two corresponding 2D points existing. One is an image point in one of the image sequences and another is a point within the slide points. Gotten the two 2D coordinates of the points, the 3D coordinates of the space points on the surface of the solid of rotation can be calculated by the collinear equations. The sequential images are taken from different directions of the solid of rotation. Using the correspondence of whole adjustment and the inherent structure characteristic of the solid of rotation, the 3D coordinates of all space points projected on the whole surface of the solid of rotation can be computed out entirely. The 3D model of this solid of rotation is acquired by connecting all neighbour space points. This approach is flexible and practical, which are confirmed by the results of the reconstructing experiments
