To accurately obtain the 3-D coordinates of key points of large-size industrial products or some work pieces with deep holes, two kinds of optical, contact and portable probe systems were studied and implemented based on the theory of close-range photogrammetry and stereo vision technology. The key technologies applied in the systems were studied, including probe design, probe calibration and 3-D point reconstruction. Two kinds of probes, dot-matrix and hand-camera, were designed to apply to different industrial product measurements. Then, for the dot-matrix probe measurement, a point cloud registration method was proposed to solve the relationship beween probe coordinate system and world coordinate system. Besides, a method of fitting the virtual ball was used to calibrate two probes. Finally, four standard balls were measured in an accuracy test. The comparison results from three-coordinate measuring machine show that the measurement accuracy of the system can be up to 0.1 mm/m. It suggests that the system has met the general accuracy standards of the three-dimensional point measurement of medium and large sized products.
