Abstract

Aiming at these problems in real-time measurement about multiple targets in large scale, we propose a vision measuring method with CCD Rotation Ranging System (CRRS) to achieve the dynamic measurement with high-accuracy. CRRS is composed of mechanical rotating platform and Area scan CCD camera. The CCD camera is fixed on a mechanical rotating platform which is droved by motor. Firstly, we calibrate the CCD camera before the measurement. Secondly, the two CCD cameras is revolved and pitched by the rotating platform to measure a fixed field of the large area with high precision. The two CCD cameras composed of a Binocular stereo vision system to measure the local coordinates of the target. Thirdly, the poses of two CCD cameras are got from the rotating platform, so we can translate the local coordinates of target to the global coordinates. The experiment results show that, the measurement device can measure the targets precisely and efficiently, with non-contact the rotation CCD probe.
