6 CONCLUSIONS AND FURTHER WORK
Camera calibration and acquisition of 3D spatial data using the stereo vision system have been investigated in this paper.
Fitting the stereo adapter to the lens of the CCD 2 camem, stereo image can be obtained with one camera, and stereo
image sequences for wide area also obtained rotating the video theodolite. Furthermore, 3D spatial data can be obtained
simultaneously. And camera calibration for the stereo image can be performed with one control point since the rotation
parameters and stereo image can be acquired simultaneously.
The effectiveness of the stereo vision system not only human motion, auto-tracking and realtime positioning of a
moving objects but also acquisition of 3D spatial data were demonstrated. There are issues, however, for further work.
These problems are automatic modeling, texture mapping. And from the test, positioning errors can be found due to the
short of baseline of the stereo adapter, but it is concluded that the stereo vision system is a useful tool in a small inner
space.
With this circumstance, a stereo vision system is expected to become a useful tool in various photogrammetric fields
since the stereo image sequences and the camera rotation parameters can be acquired in real-time.
