A natural application of our extremely high speed surface perception technology to robotics and autonomous guided vehicles took the form of the developmental M1 project. Originally proposed for a 1998 DARPA mobile robotics project, a high performance radio controlled chassis was fitted with a miniaturized optics package. The vehicle images the terrain ahead at 30 frames per second, calculating the 3-D contours on the fly to facilitate obstacle avoidance.
Podiatry and Footwear
Designed in 1994 the ScanCast 3-D® was conceived as a tool to eliminate the in-office use of plaster casting for Podiatric orthotics. As a self-contained, PC based system, ScanCast allowed the physician to input all patient pathology and prescription information via touch screen. A digital copy of the plantar surface of a patient's foot was performed in 1/30 second and transmitted to the orthotic production laboratory. A large number of these systems were installed at hospitals and clinics throughout the United States, Canada, Sweden, Norway and Korea. A derivative of this product was The Custom Foot scanning system used at a number of retail custom shoe facilities in malls throughout the United States.
Principal application of the technology has been in the medical field for soft tissue surface reproduction. Contact surface reproduction is impractical with the inherent mess of plaster casting, or the inaccuracies of foam impressions. The slow data rates of existing laser point or line range scanning devices introduce unacceptably large errors due to patient movement (aspiration, tremors, etc.) Our technology as a full field, strobe based data acquisition system eliminates this problem. Freezing the target's motion in time with flash illumination, each element in a two-dimensional sensor array returns a corresponding three-dimensional coordinate for the target surface. This perception technology has been successfully applied to a number of our products for mapping human body surfaces. Hundreds of thousands of digital surface maps from these devices have provided countless patients with a higher level of function and comfort.
Working to advance Computer Generated Imagery or CGI, our development team has demonstrated 3-D data acquisition at 30 frames per second. Our focus is generation of high resolution (megapixel) 3-D surface data at video frame rates. We are exploring these incredibly high speed 3-D perception rates for use in mobile robotic vision applications and the motion picture industry where animation may be generated from digitally reconstructed surface data of an actors' facial expressions or dialogue.
Virtual 3-D continues to provide unique solutions to applications demanding high speed, high quality 3-D perception.
