| Abstract: | A non-contact 3D surface measurement system based on binocular vision was introduced in this paper. The large or cylindrical workpiece can be measured partially and realized accurately, then the digital model of integrated surface can be obtained. The principles of system includes calibration, spatial code, stereo matching, 3D coordinate calculation, 3D registration and curving surface reconstruction were described. The result of examinations for measurement of aircraft skin shows the system is reliable, accurate and practical. |
