Abstract
Projection device switches and projects a plurality of types of pattern images in a unit of projection frame. Imaging device images object to which the pattern image is projected and generates image data. Measurement device discriminates whether each imaging frame is a key frame of the image data obtained by capturing one of the pattern images or a blended frame of the image data obtained by capturing a plurality of the pattern images switched during an exposure period of one frame, and performs measurement based on a space coding method by using at least the image data of the key frame.
