Abstract

Imaging methods aid a user in understanding relative depths of objects or topography within a field of view. In one method, image data is gathered using 3D image sensors, while illumination of an area of interest is alternated with projection of a pattern onto the area of interest. The captured image data is used to display a 3D true color image; a monochrome grid on surfaces of the area of interest; a 3D true color image with a monochrome grid on surfaces of the area of interest; a 2D or 3D false color image where different colors identify different depths of regions of the area of interest; and/or a 2D or 3D true color image of an area of interest with features in the area of interest located a first depth relative to the image sensors highlighted with a common color. In another method, 3D image data is used to generate a 2D image that highlights features at a common depth using the same color.
