Abstract
A high-speed modeling system and a method of constructing a model are disclosed herein. In one embodiment, the system comprises first and second cameras, a control portion to synchronize the first and second cameras, and a projector of electromagnetic patterns. The first and second cameras are synchronized by the control portion to generate second frames a time interval after first frames are generated to thereby obtain a high frame-rate which is higher than the frame-rate of the first camera. Multiple imaging stations comprising first and second cameras may be directed to the path traveled by a mass at a high speed, in a prescribed arrangement, to model the mass with the high frame-rate system.

A high-speed modeling system comprising:
- a master image sensor producing master signals corresponding to a path portion of a path traveled by a mass;
- at least one slave image sensor producing slave signals corresponding to the path portion;
- a projector directing an electromagnetic radiation pattern to the path portion that generates first and second reflections when the electromagnetic radiation pattern intersects the mass;
- a master processing portion generating a master frame based on the master signals, the master frame having a master pattern representative of the first reflections;
- at least one slave processing portion generating a slave frame based on the slave signals, the slave frame having a slave pattern representative of the second reflections, and the slave processing portion being synchronized with the master processing portion to generate the slave frame at a time interval after the master processing portion generates the master frame;
- and
- a second projector producing a second electromagnetic radiation pattern and third and fourth reflections when the second electromagnetic radiation pattern intersects the mass, wherein the at least one supplemental imaging station generates supplemental master and slave patterns based on the third and fourth reflections;
- wherein the master and slave patterns are operable to construct a model of the mass based on the time interval and positional relationships between the master and slave image sensors and the projector;
- wherein the master imaging sensor, the slave imaging sensor, the master processing portion and the slave processing portion comprise a first imaging station, further including at least one supplemental imaging station generating supplemental master and slave patterns, wherein the master and slave patterns and supplemental master and slave patterns, and positional relationships between the first and supplemental imaging stations, are operable to enhance the model with the addition of the supplemental master and slave patterns.
A high-speed method of modeling comprising:
- directing a electromagnetic radiation pattern to a path portion of a path traveled by a mass;
- initiating capture of a master pattern with a master imager, the master pattern representing a first reflection pattern generated when the electromagnetic radiation pattern intersects the mass;
- waiting a time interval after the initiating capture of a master pattern step;
- initiating capture of at least one slave pattern with a slave imager, the slave pattern representing a second reflection pattern generated when the electromagnetic radiation pattern intersects the mass, the at least one slave pattern being synchronized with the master pattern by the time interval;
- and
- generating a second electromagnetic radiation pattern to produce third and fourth reflections when the second electromagnetic radiation pattern intersects the mass, wherein the at least one supplemental imaging station generates supplemental master and slave patterns based, respectively, on the third and fourth reflections;
- wherein the master and slave patterns are operable to construct a model of the mass based on the time interval, a direction of the electromagnetic radiation pattern, an angle formed by the electromagnetic radiation pattern and a line intersecting the path portion and a location of the master imager, and a second angle formed by the electromagnetic radiation pattern and a line intersecting the path portion and the location of the slave imager;
- wherein the master and at least one slave patterns are generated by a first imaging station, further including the step of producing supplemental master and at least one slave patterns with at least one supplemental imaging station, wherein the master and slave patterns and the supplemental master and slave patterns are operable to enhance the model based positional relationships between the first and supplemental imaging stations.
