Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
72 words
A system for virtually modeling a physical system having immovable and movable objects, comprising: at least two video cameras, each of the video cameras being configured to provide a sequence of images, an image processing system configured to extract modulated infrared signals from the sequence of images and identify the spatial location of objects, and a virtual reality modeling system for constructing a virtual reality model using identified object spatial location information.
Claim 2
Dependent Claim
23 words
The system of claim 1, wherein a spot of modulated infrared light is directed against a predetermined object to map its spatial location.
Claim 3
Dependent Claim
27 words
The system of claim 1 or 2, wherein an infrared tag is attached to an object, with data relating to the object encoded in the infrared tag.
Claim 4
Independent Claim
91 words
A system for precisely locating a spot of light, comprising: at least two video cameras, with each video camera configured to provide a sequence of images at a first frame rate, a light pointer directing a series of identifying light signals at a second rate, less than the first frame rate, with a reflection of the identifying signals being perceptible by the video camera as a modulated light spot, an image processing system configured to extract a three dimensional spatial location of the modulated light spot from the sequence of images.
Claim 5
Dependent Claim
14 words
The system of claim 4, wherein the identifying light signals are infrared light signals.
Claim 6
Dependent Claim
34 words
The system of claim 5, further comprising a scanning mechanism for automatically providing a series of modulated light spots, with each light spot spatially separated from another and having a unique identifying light signal.
Claim 7
Independent Claim
84 words
A system for precisely locating positions of reflective surfaces, comprising: at least two video cameras, each video camera providing a sequence of images, a light pointer for directing a series of identifying light signals at a reflective surface, a reflection of the identifying signals being perceptible by the video camera as a modulated light spot, and an image processing system configured to extract a three dimensional spatial location of the modulated light spot from the sequence of images derived from two or more cameras.
Claim 8
Dependent Claim
14 words
The system of claim 7, wherein the identifying light signals are infrared light signals.
