A three dimensional (3-D) image is generated from a plurality of portions of an image of an object, each captured portion of the image is based on a scan width of an image capture device. A range finding device obtains at least one range data value for each captured portion of the image as at least one corresponding position in each captured portions of the image, and a base to which the image capture device and the range finding device are mounted moves in increments based on the scan width of the image capture device.
