摘要:Recently, spatial data acquisition for virtual environment applications, 3D objects modeling, 3D - GIS and so on have been extensively carrying out using laser-range finder or photogrammetric method. However, there are some issues for rapid reconstruction of objects and visualization of 3D special data. These problems include texture mapping in the case of laser-range finder and camera calibration aspects in photogrammetry. In order to resolve the twin issues, a stereo vision system which a stereo adapter was fitted to a lens of a CCD camera of a video theodolite was constructed so that stereo image can be acquired with one CCD camera. The most remarkable points for this stereo vision system are follows; 1) Camera calibration can be performed with one control point since the camera rotation parameters and the synchronized stereo image Sequences can be acquired simultaneously. 2) Stereo image can be acquired with one CCD camera since right and left image are taken as the odd field and even field by a liquid crystal shutter. A test was performed in the laboratory using a stereo vision system, and system evaluation for 3D object modeling was investigated
