3-D Measurement and Reconstruction of Workpieces in Robotic Stereovision System

摘要：

　　An epipolar line constraint equation for robotic binocolar stereovision(BSV) is first established for the measurement and reconstruction of workpiece surface,in which the intrinsic parameters of two cameras and their extrinsic structural parameters with respect to a robotic reference base are included.To determine a sole matching point between left and right images,a laser emmiter is added to BSV to form a stripe on workpiece surface,experimental results show that the measurement accuracy of 3-dimensional (3-D)workpiece surface can be improved by combining epipolar line constraint with laser stripe projection,and the 3-D workpiece surface can be reconstructed with less errors.
