The Islamic art accuracy has been studied using the digital close range photogrammetric technique. One Islamic art
element has been chosen as an Islamic art guide. This element is the painting of the mosques’ ceilings. The
photogrammetric technique has been applied and the results have been compared. The comparison results shows that the
standard deviation of the dome axis are oXo — 0.0056 m and oYo = 0.0033 m which calculated from symmetrical points
around the dome axis. This values considered as a high accuracy. The other comparisons shows that the standard
deviation of the dome profile and the lengths are about 3.5 cm. This value considered as a good accuracy if we took into
consideration the another two factors that effecting in this values (the painting base as a construction and the accuracy
of the used photogrammetric technique) and the effect of the third direction (Z). The geometric comparison shows that
the Islamic art is very accurate in dimension and shapes.
From this investigation, we can conclude that the Islamic art is very accurate in shape and dimension as obtained from
the numerical and geometrical results that obtained from the digital close range photogrammetric technique.
