Portable three-dimensional scanner and method of generating a three-dimensional scan result corresponding to an object

A method of generating a three-dimensional scan result corresponding to an object, wherein a portable three-dimensional scanner applied to the method comprises at least two image sensing units and a depth map generation unit, the method comprising:

• when the portable three-dimensional scanner is moved around the object, a first image sensing unit of the at least two image sensing units captures a plurality of first images comprising the object, and a second image sensing unit of the at least two image sensing units captures a plurality of second images comprising the object, wherein each first image of the plurality of first images corresponds to a second image of the plurality of second images, and when the first image sensing unit captures the each first image, a corresponding distance exists between the portable three-dimensional scanner and the object, wherein the plurality of first images or the plurality of second images are color images, and the corresponding distance is varied with time;
• the depth map generation unit generating a corresponding depth map according to the each first image and the second image;
• and
• generating and outputting a color three-dimensional scan result corresponding to the object according to a plurality of depth maps generated by the depth map generation unit, the plurality of first images, and the plurality of second images.
