Abstract：

Aimed to resolve the practical problems about the strain measurement in the process of sheet metal forming, a new measurement method based on the theory of photogrammetry and coordinate grid method was proposed. The surface strain size and distributions can be quickly and accurately calculated by this method. Meanwhile, a strain measurement system XJTUSM which is available in the practical production was designed and developed according to the new method. The effectiveness of this method was measured by testing the surface strain of some types of sheet metal parts surface strain.
