Method and apparatus for dynamic space-time imaging system
First Claim
Patent Images
1. A method for creating a three dimensional map of the surface of an object, including the step of:
- selectively projecting at least one pattern of lines on at least one portion of the surface of the object;
digitally capturing the image of said at least one pattern on the object;
calculating the distance of each incremental portion of the image to the object, and storing the distance data to comprise the three dimensional map;
rendering a three dimensional image of the at least one portion of the surface of the object using the data from the three dimensional map;
further including the step of establishing a fiducial distance from said image to said object, and scaling said distance data according to said fiducial distance;
said step of establishing the fiducial distance including projecting a pair of parallel light rays onto said object, said pair of rays having a known spacing, said light rays forming point images on the object having the same known spacing.

Abstract
A method for creating a 3D map of the surface contours of an object includes projecting a variety of patterns onto the object, and imaging the patterns as they fall on the object to encode the topographic features of the object. The images are processed in a computer program in a manner such that a complete 3D map of the surface of the object is obtained in digital form. Reiteration of the method can detect motional variation such as a breathing human, flexure of a complex mechanical structure, or a stress-strain testing of an airplane, vehicle, beam, bridge, or other structure.
