1. A three-dimensional model generation method executed by an information processing device, the three-dimensional model generation method comprising:
obtaining a first three-dimensional model generated by a measuring device that emits an electromagnetic wave and obtains a reflected wave which is the electromagnetic wave reflected by a measurement target, the first three-dimensional model including first position information indicating first three-dimensional positions in the measurement target;
obtaining a multi-viewpoint image generated by one or more cameras shooting the measurement target from different positions; and
generating a second three-dimensional model of the measurement target based on the multi-viewpoint image and the first three-dimensional model by enhancing color definition of the first three-dimensional model using the multi-viewpoint image, the second three-dimensional model having an increased amount of color information per unit area relative to the first three-dimensional model.
