Title:
THREE-DIMENSIONAL SHAPE MEASUREMENT DEVICE, METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2016125917
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a three-dimensional shape measurement device that can be made compact and low-priced.SOLUTION: A mask 8 where two or more spirals having a light shield part and a translucent part arranged alternately are formed and a transparent texture acquisition window is formed in a region corresponding to a quarter of the whole is mounted on the back of a mobile terminal MT. Then a texture image of an object to be observed is acquired through the texture acquisition window of the mask 8 first. A gray code pattern is projected on the object to be observed by performing irradiation with light of the light 3 of the mobile terminal MT through the mask 8 while the mask 8 is rotated by a vibration notification motor 4 of the mobile terminal MT. In this state, the object to be observed is photographed using the camera 2 of the mobile terminal MT, three-dimensional coordinates of the object to be observed are obtained using image data thereof and a previously generated lookup table, and the three-dimensional coordinates and color information of the texture image are output as measurement results.SELECTED DRAWING: Figure 5
