Recently, a flexible three-dimensional measuring system is required to analyze and evaluate the motion accuracy of a moving object such as robot manipulator hands. This study deals with the measuring method which can measure precisely an object position in a 3D spatial range. Measuring method was based on the triangulation, and a spherical lamp target with high roundness and two cameras were used. The target edge detection based on the straight line approximation was presented. That is possible to acquire the target center of gravity with high precision. Lens distortion was corrected by the databases composed of distortion position data and ideal position data. As a result, 100 μ m measuring precision was obtained in 100 × 200 × 200 mm spacious range with 700mm distance from target to cameras.
