Abstract :
Both metric and non-metric cameras are used
in photogrammetry, but the most common use is for
non-metric cameras. Since its calibration is very
important to calculate the internal orientation elements
of the camera, the calibration method is very important.
One of the most accurate methods is the pre-calibration
method, in which a test field is usually used. There are
many types of test fields, some of which are standard and
some are locally made. Because of the cost and variety of
applications, home-made is used. The test field industry
involves many factors such as the quality of the points,
their size, and the material the test field is made of.
Several types of test fields were tried in this research.
The best two models of these types were selected, and
then the two models were compared in terms of the
effect of the material from which they were made. The
effect of the material and choosing the appropriate
pattern gave calibration results that reached one-micron
accuracy.
