1. A three-dimensional image processing apparatus comprising: a processor that obtains, from each of a plurality of visible light image sensors having mutually different image capture points, visible light image data of the scene as viewed from the image capture point; the processor generating three-dimensional model data expressing a target contained in the scene; the processor setting a point of view for the scene; and the processor rendering display image data expressing the scene as viewed from the set point of view based on the three-dimensional model data and the plurality of pieces of visible light image data having mutually different image capture points, wherein in the case where there are a plurality of pieces of visible light image data corresponding to a region on a surface of the target expressed by the three-dimensional model data, the processor selects one of the pieces of the visible light image data in accordance with the set point of view and renders the region corresponding to the surface of the target based on the selected visible light image data and the three-dimensional model data, wherein the processor selects one of the pieces of the visible light image data in accordance with a positional relationship between the point of view and the image capture point, and wherein the processor selects one of the pieces of the visible light image data in accordance with the magnitude of angles formed between an image capturing direction of each visible light image sensor and a direction of the set point of view.
