Claim 12:
13. A three-dimensional imaging device comprising at least one digital image sensor, a memory and a calculating unit comprising hardware and software means to perform:
receiving at least two two-dimensional digital images representing an observed three-dimensional scene, acquired by at least one determined image sensor from at least two respective positions in space;
generating, from the two-dimensional digital images, based on a stereoscopic three-dimensional reconstruction calculation method, a first intermediate three-dimensional numerical model associated with the observed three-dimensional scene;
generating, from the two-dimensional digital images, based on a method of three-dimensional reconstruction calculation by learning, a second intermediate three-dimensional numerical model associated with the observed three-dimensional scene;
generating, by combination of the first and second intermediate three-dimensional numerical models, a final three-dimensional numerical model, with said generation comprising selecting, for a determined portion of the final three-dimensional numerical model, a corresponding portion of that of the first and second intermediate three-dimensional numerical models which maximizes a quality criterion of the representation of the observed three-dimensional scene based on a comparison of at least one characteristic parameter of said first and second intermediate three-dimensional numerical models for said corresponding portion which is representative of the quality of the representation of the observed three-dimensional scene;
storing, in a memory, digital information comprising at least one received two-dimensional digital image, the final three-dimensional numerical model associated with said two-dimensional digital image, and a characteristic parameter of said final three-dimensional numerical model, representative of the quality of the representation of the three-dimensional scene observed; and,
using stored digital information as learning data to train and retrain the calculating unit for the execution of the method of three-dimensional reconstruction calculation by learning.
