First Claim
1. A system for three-dimensional modeling and restitution of a subject of a determined scene in a three-dimensional space having three axes in a three-dimensional frame of reference, the system comprising:
- a first subsystem comprising, at least one portable video camera configured to acquire sequences of digital images of said subject, first and second series of measurement devices cooperating with said at least one portable video camera and generating data measurement signals relative to each of said axes in said three-dimensional frame of reference, so as to characterize the attitude, location, and displacement of said at least one portable video camera relative to said three axes in said three-dimensional frame of reference;
a second subsystem comprising at least a digital data processor configured to receive signals characterizing said sequences of acquired digital images and said data measurement signals, and responding to said received signals characterizing said acquired sequences of digital image and said data measurement signals to generate a three-dimensional model of said subject; and
connection means coupled between said first and second subsystems, said connection means configured to convey at least said signals characterizing said acquired sequences of digital images and said data measurement signals, and whereinsaid first series of measurement devices further comprises a trihedron of three gyros, each gyro being in alignment with one of said axes of said frame of reference; and
said second series of measurement devices further comprises a trihedron of three accelerometers, each accelerometer being in alignment with one of said axes of said frame of reference.

Abstract
A system for three-dimensionally modeling and restitution a subject, the system comprising a housing suitable for being carried in the hand by an operator, the housing having an optical unit with stereoscopic digital video cameras co-operating with an inertial navigation unit having a trihedron of optical fiber gyros and a trihedron of accelerometers for generating position and displacement signals in a frame of reference. The housing may also include, in particular, a telemeter laser, an infrared video camera, a GPS unit, inclinometers, and tri-flux magnetometers. A second subassembly connected to the housing by an optical and/or electrical connection cable contains an electrical power supply, electronic circuits, and a microcomputer for processing signals delivered by the housing and for generating a three-dimensional model of the subject, implementing a photogrammetric technique.

12. A method of modeling and restitution in three dimensions, a subject of a determined scene in a three-dimensional space having three axes in a three-dimensional frame of reference, the method comprising:
-
recording a video using at least one portable video camera to acquire digital image sequences of said subject, and generating data measurement signals, comprising at least two series of signals characterizing attitude, location, and displacement data of said at least one portable video camera; transmitting said signals characterizing said acquired digital image sequences and said data measurement signals characterizing the attitude, position, and displacement of said at least one portable video camera to an associated digital data processor; storing data from said transmitted data signals in a store associated with said digital data processor; and processing said signals by determined software under the control of said digital data processor so as to generate a three-dimensional model of said subject by combining said data associated with said signals characterizing said acquired digital image sequences and said data signals characterizing the attitude, location, and displacement of said at least one portable video camera while recording said video, and wherein the generating data measurement signals is performed by; a first series of measurement devices including a trihedron of three gyros, where each gyro is aligned with one of said axes of said frame of reference; and a second series of measurement devices including a trihedron of three accelerometers, where each accelerometer is aligned with one of said axes of said frame of reference. - View Dependent Claims (13, 14, 15, 16, 17, 18)
