IPC: G01R31/00
Filed: 1997-04-01
Abstract: In a FLIR/laser based targeting and imaging system, the ability to recognize, detect, locate, and/or track targets in an area of interest is significantly improved by reducing the fixed and dynamic alignment errors between the IR LOS and the laser LOS. Fixed alignment errors between the IR LOS and the laser LOS. Fixed alignment errors are reduced with an improved internal boresight module (Fig. 10) and corresponding boresight method. Dynamic alignment errors are reduced with an opto-electric subsystem that employs a single pitch (405) bearing and a common pitch/yaw afocal (401) for both the laser energy and the IR energy. A segmented window (Fig. 17) in the system housing includes a circular EMI grid pattern (Fig. 19) which significantly reduces the amount of off-axis EMI entering the optical pathways, and improved signal processing techniques (Fig. 26) are employed to enhance the quality of the IR image after the image has been digitized.

Patent CA-2279100-A1 (CA)
Title: Display techniques for three-dimensional virtual reality
Inventor: EDMARK JOHN T
IPC: G06T15/10
Filed: 1999-07-29
Abstract: A limitation of using two-dimensional images, such as videos or photographs, to represent portions of a three-dimensional world occurs when the user moves within the world and views the world from a location different than from the original context of the two-dimensional image, i.e., from a location different than the image's ideal viewing point (IVP). View changes result in the image not aligning well with the surrounding objects of the three-dimensional world. This limitation is overcome by distorting the two-dimensional image so as to adjust the image's vanishing point(s) in accordance with the movement of the user using a pyramidic panel structure. In this manner, as the user moves away from the ideal viewing point, the distortions act to limit the discontinuities between the two-dimensional image and its surroundings. To minimize the depth profile of the pyramidic panel structure, the structure may be segmented into sections and each section translated towards, or away from, the user's viewpoint.
