This paper presents a circular protractor based 3 D data integration technology by using calibrated binocular stereo rig. The binocular vision system mounted on a step motor controlled turntable is panned to photograph the large scale scene from multiple views. Through corresponding rotation angle and coordinate transformation between views, 3 D data of scene from different views can be merged into a uniform reference frame with high accuracy. Parameter calibration of the turntable and the coordinate transformation between multiple views at the fixed viewpoint are discussed. With only one calibration, this novel method can capture and reconstruct the 3 D close range scene. Experiment results show that this method can achieve higher integration precision.
