In recent years, three dimentional geometric shapes represented on computer systems have been widely used in areas both CAD/CAM (Computer Aided Design / Manufacturing) and Computer Graphics. However, input of such shapes, especially including surface shapes, requries much time and work. Many researches have been addressed for this topic, for examples, 3 D shape reconstruction from unorganized points from non-contact laserscanning machines, and 3 D shape recognition by stereos, and so on. In these methods, machines for measuring physical objects are generally expensive, and requires some special treatments for the measurement.<BR>Our purpose is to recover 3 D shapes be use of a general 35 mm still camera, which are relatively low cost and easily obtained. We develop a new system <I>pers</I> for obtaining 3 D shapes from pictures. By using <I>pers</I>, 3 D shapes are reconstructed as follows : (1) Prepare several pictures for objects, and take into computers as digital images. (2) Using more than five points which positions in the world coordinates and corresponding image coordinates are known, <I>pers</I> calculate camera parameters (focal parameters of cameras, a camera rotation, position) . (3) Calculate 3 D points on the objects by interactively selecting two points between two points between two images to bet polygonal faces from 3 D points.
