Abstract
A three-dimensional image generation device and a three-dimensional image generation method are provided. The three-dimensional image generation device includes multiple cameras using imaging elements, and a control unit that processes respective images captured by the cameras. The control unit sets multiple voxels in a space including a target object; images the multiple voxels from multiple directions; (a) detects each brightness of each imaging clement corresponding to one voxel among the multiple voxels; (b) specifies the lowest brightness among the detected brightnesses as the lowest brightness of the one voxel; (c) specifies, when the specified lowest brightness is at least a prescribed threshold value, the one voxel as a specific voxel including the target object; repeatedly executes the operations of (a) to (c) for all of the multiple voxels; and generates a three-dimensional image of the target object by connecting the multiple specific voxels specified in (c).
