Method and device for obtaining a stereoscopic signal
First Claim
1. A method of obtaining a stereoscopic signal from a sequence of monoscopic images comprising the following steps:
- obtaining (S10) a sequence of monoscopic images having been captured by an image acquisition apparatus in an acquisition mode enabling several images to be shot in the course of a regular movement substantially tangential to the plane of the lens of the acquisition apparatus. forming (S31) pairs of images from the sequence of images, each pair being formed on the basis of a predetermined temporal distance;
calibrating (S32) the images of the pairs formed, so as to improve the visual correspondence between the two images;
constructing (S33) a stereoscopic signal from the pairs so calibrated.

Abstract
The invention relates to a method of obtaining a stereoscopic signal from a sequence of monoscopic images. The method firstly comprises a step (S10) of obtaining a sequence of monoscopic images having been captured by an image acquisition apparatus in an acquisition mode enabling several images to be shot in the course of a regular movement substantially tangential to the plane of the lens of the acquisiton apparatus. That step is followed by a step (S31) of forming pairs of images from the sequence of images, each pair being formed on the basis of a predetermined temporal distance then a step of calibrating (S32) the images of the pairs formed, so as to improve the visual correspondence between the two images; Finally, a stereoscopic signal is constructed (S33) from the pairs so calibrated.
