Recently, sampling moire method was developed to analyze the phase of a one-dimensional or two-dimensional grating on an object with high accuracy. In the method, several phase-shifted moire patterns are generated from one image of the grating. In order to analyze a shape by a stereoscopic method, it is necessary to find the corresponding points between the two images of the object recorded from different two cameras. It is possible to analyze the phase of the grating using the sampling moiré method and find the corresponding points as points with the same phase. It is also possible to analyze the displacement and strain from the corresponding point before and after deformation. This method is, therefore, suitable for shape and strain distribution measurement of a moving object. In this paper, a dynamic shape and strain measurement method using the sampling moiré method is proposed and a system for the measurement is developed. The principle of the method, the measurement system, and the experimental results applied to a rotating tire running at the speed of 80 km/h are shown.
