    The determination of the roof crones deflection is the generally measurements in the industrial halls. The measurements is inhibited by particular condition of the operation in high industrial halls: movements and vibration (if the production is not stopped), the movements of the different conveyance and dust. If the production is stopped still remain the problems with high, danger (high voltage), weak lights, inhibit access and time restriction. Due to problems of leveling measurement the deflection of cranes in high halls, the one-images photogrammetric method is very often the best. It was use in analogue version. The digital photogrammetry shows the new possibility. In this paper three methods are presented: analogue, digital-analogue (the scanned images measurements on the photogrammetric station), and automatic image processing. The description of used technologies made rich about conclusion and recommendation for the next performers. The results of the experimental measurements and their accuracy are presented. Presented results allows to treat these described photogrammetric method as fully useful and value in accuracy. The advantages of the digital technology particular allows to recommend its for universal use.
