To reduce occlusion generated between optical devices and allow a sufficient measurement from a short distance of even a concavo-convex object.SOLUTION: The present invention includes: projection means for projecting a predetermined pattern to an object; and imaging means for imaging the object, to which the predetermined pattern is projected. The imaging means includes: a stereo camera including a first camera and a second camera; and a color camera, and a plurality of cameras of the imaging means are arranged around the projection means.SELECTED DRAWING: Figure 3 【課題】各光学デバイス間で発生するオクルージョンを低減し、凹凸がある対象物でも近距離で十分に測距する。【解決手段】所定のパターンを対象物に投影する投影手段と、前記所定のパターンが投影された前記対象物を撮影する撮影手段とを備え、前記撮影手段は、第１のカメラ及び第２のカメラを含むステレオカメラと、カラーカメラとを含み、前記投影手段の周囲に、前記撮影手段に含まれる複数のカメラが配置される。【選択図】図３
