The accuracy for 8 check points on the image is + 
27.6mm(X,Y) and = 139.8mm(Z) .This may be because, 
1. the center of the target is not clear due to halation. 
2. arrangement of control points are not uniform. 
However, considering 50mm error is admitted even if 
plane-table surveying were performed with 1/100 scale 
using 0.5 pencil,a photogrammetric system with wireless 
CCD camera is still considered satisfactory for the 
purpose of this paper. 
Figure 10 shows a display for semi real-time stereo 
matching for site recording and the results are shown in 
Figure 11. It took 10 seconds per point for stereo 
matching. Consequently Figure 11, which consist of 180 
points, required 30 minutes.
