Definitions

  • the present invention relates to a device for taking 360° panoramic images.
  • devices with a limited field of view are mounted on supports with 360° scanning mechanisms, for taking images of the surrounding space with a series of exposures, and the images obtained during the scan are placed side by side in the sequence of exposures to form a mosaic of adjacent photographs.
  • the resulting panoramic image does not correspond to a recording of the surrounding space made at a single moment in time.
  • lens assembly with wide-angle optics is the so-called fisheye, which is capable of taking the scene with an azimuth of 360° and a maximum elevation of +90°, but which, however, has the drawback of providing a very distorted image.
  • the size of the circular image depends on the focal length of the optical system, and the relative size, i.e. the size of the inner radius of the hole with respect to the outer radius of the circular image, depends on the choice of maximum elevation (absolute value) that the user wishes to obtain.
  • US Patent no. 6373642 discloses a device with a catadioptric system which is constituted by a refractive transparent lens, with a substantially vertical axis of revolution, which has a concave surface and a reflective convex surface.
  • the catadioptric system is capable of capturing 360° of light from the surrounding panoramic scene and reflecting it in a lens assembly with a plurality of lenses, which is arranged in a downward region, in order to dimension the field of view on the focal plane and correct the optical aberrations.
  • the device 10 moreover comprises a lens assembly 14, which has a substantially cylindrical shape and is arranged so that the optical axis 15 passes through the center of curvature 16 of the spherical lens, and which contains an optical system of lenses to dimension the field of view on the focal plane and correct optical aberrations.
  • a lens assembly 14 which has a substantially cylindrical shape and is arranged so that the optical axis 15 passes through the center of curvature 16 of the spherical lens, and which contains an optical system of lenses to dimension the field of view on the focal plane and correct optical aberrations.
  • the sleeve 17 is rendered integral with the catadioptric system 1 1 by being inserted with its upper end 17a into a complementarily shaped groove 19 which is formed on the convex surface
  • the image of the object 26 is focalized at point 26a on the outer rim of the panoramic image 25 and, similarly, the images of the objects 27 and 28 are reproduced respectively at points 27a and 28a.

Abstract

La présente invention concerne un dispositif (10) permettant de prendre des images panoramiques à 360° et comprenant : - au moins un système catadioptrique (11) qui est constitué d'une lentille sphérique transparente et qui comporte une surface convexe (12) et une surface concave réfléchissante (13) qui sont parfaitement concentriques, - au moins un ensemble objectif (14) qui a une forme sensiblement cylindrique, qui est agencé d'une manière telle que l'axe optique (15) passe par le centre de courbure (16) de la lentille sphérique et qui est relié d'un seul tenant au système catadioptrique (11) au niveau de la surface convexe (12) au moyen d'un manchon (17) qui relie l'ensemble objectif (14) au système catadioptrique (11), et - au moins un capteur d'images (18) permettant un traitement numérique des images obtenues.
