System for displaying combined imagery
First Claim
1. A system for displaying combined imagery, comprising:
- at least one photographing device for obtaining a first two-dimensional image of an object;
at least one distance measuring device for measuring a first distance information with regard to each point on a surface of said object represented by said first two-dimensional image;
an information output device for outputting a second two-dimensional image and a second distance information with regard to each imagery of each pixel represented by said second two-dimensional image; and
means for comparing said first distance information with said second distance information with respect to each pixel, selecting image data which represent either one of said first two-dimensional image and said second two-dimensional image which is disposed closer for said each pixel, and displaying said image data;
wherein, said at least one distance measuring device comprises;
a light-emitting unit for emitting a light pattern;
a sensor for receiving said light pattern when it has been reflected on the surface of said object; and
a half mirror disposed in a path of said light pattern incident on said photographing device and adapted to direct a fraction of said light pattern towards said sensor.

Abstract
A video see through AR system capable of obtaining correct depth information with respect to each pixel representing a two-dimensional image is disclosed so that a portion of imagery which should appear in the background of a final picture may be properly hidden behind imagery which should appear in the foreground of the final picture. A photographing device is provided for obtaining a two-dimensional image of a real object field disposed in conjugate relationship with an observer'"'"'s eyes. Also provided is a device for measuring distances with respect to each pixel to the real object to be measured. The measured distance is compared with the distance to virtual imagery with respect to each pixel and the pixel which represents the imagery disposed closer to the observer is selected for the formation of combined imagery, which is displayed on the screen of a display device.

2. A system for displaying combined imagery, comprising:
-
at least one photographing device for obtaining a first two-dimensional image of an object; at least one distance measuring device for measuring a first distance information with regard to each point on a surface of said object represented by said first two-dimensional image; an information output device operable, on the basis of an observer'"'"'s visual point and prestored information on virtual objects, for outputting a second two-dimensional image and a second distance information with regard to imagery of each pixel represented by said second two-dimensional image; a comparator for comparing said first distance information with said second distance information with respect to each pixel; a selector operable, on the basis of an output of said comparator, for selecting image data which represent either one of said first two-dimensional image and said second two-dimensional image which is disposed closer for said each pixel; and at least one display unit for displaying said first two-dimensional image blended with said second two-dimensional image such that a portion of displayed images represents said either one alone; wherein, said at least one distance measuring device comprises; a light-emitting unit for emitting a light pattern; a sensor for receiving said light pattern when it has been reflected on the surface of said object; and a half mirror disposed in a path of said light pattern incident on said photographing device and adapted to direct a fraction of said light pattern towards said sensor. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
