extracts the slit light from the contents of these two memories and finds corresponding points on the images from the two television cameras in the vicinity of the corresponding points of the slit light. An image processing device comprising an arithmetic unit that sequentially finds corresponding points other than the slit light by correlation or the like, and calculates the three-dimensional coordinates of the corresponding points based on the principle of triangulation from the coordinates of the corresponding points other than the slit light on the image. A three-dimensional image measuring device using stereo matching, characterized in that it has a configuration including:
