3D imaging apparatus

A 3D imaging apparatus includes: a first image capturing camera generating a base image to be used for obtaining a first range image showing a three-dimensional character of an object; a second image capturing camera generating a reference image to be used for obtaining the first range image; a stereo matching unit searching for corresponding pixels between the base image and the reference image, and generating a first range image by calculating a disparity between the corresponding pixels; and a light source emitting to the object infrared light whose intensity is modulated. The first image capturing camera further generates a second range image by receiving a reflected light in synchronization with the modulated intensity. The reflected light is the infrared light reflected off the object. The second range image includes range information on a range between a point of reflection off the object and the first imaging unit.
