Abstract
An automatic all-around three-dimensional shape measurement system is introduced. Striped patterns from an optical modulator are projected on the surface of the object. By rotating the precision work-table, the deformed patterns were recorded by a CCD camera from different angles and stored in a computer, and the 3D coordinates of the surface of the object were calculated according to geometric relations. Thus from an arbitrary direction, 2D views and 3D solid models of the measured object may be constructed conveniently. After a series of image processing, the sizes of object may be measured. With this system, it is possible to capture the surface topography far away from the object. The error influence factors of the system and image processing are analyzed. Experiments show the measurement process and the effect of the measurement.
