Method and apparatus for dynamic space-time imaging system
First Claim
1. A method for creating a three dimensional map of the surface of an object, including the step of:
- selectively projecting a sequence of patterns on at least one portion of the surface of the object, including an initial flash pattern and at least one secondary pattern;
digitally capturing the image of said sequence of patterns 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 said at least one portion of the surface of the object using the data from the three dimensional map.

Abstract
A method for creating a 3 D 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. In one embodiment a three dimensional image is taken in a single flash to avoid blurring due to motion of the object. Thereafter a secondary pattern is projected to detect changes in the initial image. 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.
