Table 2 illustrates the results of the matching 
precision for the same targets (with the same charac- 
teristics), The image matching technique used here 
is based on least squares method. 
The results of these tables are not necessary to 
comment. It is better to apply the circular targets in 
all cases ( from the point of view of precision). 
However, in some cases ( when the angles of camera 
inclination are very large) itis better to use the cross 
targets.
