Definitions
- the present invention relates to the field of acquisition of panoramic images in order to allow viewing of an environment over 360 °.
- the present invention relates more particularly to a panoramic image acquisition device, of the type comprising at least one reflecting means provided with an at least partially reflecting external surface, in order to allow said image to be reflected towards a sensor device.
- camera or camera type image
- a panoramic image is a two-dimensional image which makes it possible to visualize the environment located in a complete perimeter around a precise point with a three-dimensional effect. This kind of image is very useful to visualize a landscape of a particular point, or to visualize the interior space of a room.
- the device When the image is acquired using a camera, the device also makes it possible to carry out video surveillance.
- panoramic image acquisition devices and in particular the international patent application WO-A-99/30197 which relates to an omnidirectional device used to capture the image of a scene from a point of view. unique.
- This device comprises a substantially parabolic reflector means placed so as to reflect orthographically the main rays of electromagnetic radiation emitted by said scene. said reflecting means has a focal point which coincides with said unique view of said omnidirectional device, including said substantially parabolic reflecting means.
- This device also comprises one or more image sensors placed so as to receive said main rays of electromagnetic radiation reflected orthographically from said parabolic reflector, which makes it possible to capture the image of said scene.
- the major drawback of this device resides in the fact that: part of the field of vision of the paraboloid shape is obscured by the image sensor device; - the reflector means "sees" a part of the image sensor device, which will necessarily appear on the final image and therefore will have an impact on the quality and realism of the view;
- the present invention intends to remedy the drawbacks of the prior art by proposing a panoramic image acquisition device which makes it possible: to obscure the image sensor apparatus; - acquire an image centered on the horizontal very close to human vision; include the device in a protective box obscured on the acquired image; acquire an image making it possible to view the entire environment using a device comprising a complete field of vision; and allow for image overlays.
- the present invention is of the type described above and it is remarkable, in its broadest sense, in that it proposes to offset the starting point of the viewing angle, from the proximal end from the reflecting means towards its distal end, by producing the surface of said conical and concave primary reflecting means.
- a cone is a regulated surface whose generator passes through a fixed point, the vertex.
- a concave cone is a cone whose generator has a curvature in the direction of the axis of the cone.
- said primary conical surface is generated by a substantially parabolic generator or by a generator substantially in an arc of a circle or even by a substantially elliptical generator.
- the image obtained, whether taken with a camera or a camera, is a two-dimensional anamorphic image which allows a complete 360 ° panorama to be recreated with a three-dimensional effect. Thanks to the device according to the invention, the average field of vision is closer to the horizontal and makes it possible to obtain images very close to natural human vision.
- said reflecting means has a cone shape which includes a base having a return, in order to allow an overlap of the field of vision located behind the image sensor apparatus.
- Said reflector means can, moreover, have a cone shape which has a truncated top, in order to allow positioning of a fixing element at the level of said top.
- said reflecting means is primary and has a cone shape which has a hollowed top and the image acquisition device comprises at least one deflection surface, at least partially reflecting, making it possible to return the image to the image sensor device, for example through the hollowed-out vertex.
- This version also has a variant in which the image acquisition device comprises a secondary reflecting means provided with an external secondary surface, having a cone shape, at the less partially reflecting and concave, coaxial with the primary reflecting means.
- said secondary reflecting means having a cone shape whose secondary apex is truncated and possibly hollowed out to allow the image to pass.
- the device according to the invention does not reflect the image sensor device and it makes it possible to obtain a total field of vision.
- the device according to the invention makes it possible to obtain maximum image quality in the area of the environment which contains the most information, that is to say in the area close to the horizontal.
- the device according to the invention also makes it possible to place the reflective surface or surfaces in a protection device situated outside the field of vision of the image acquisition device. Thanks to the relevance of the field of vision offered with the device according to the invention, it is possible to use it for very specific applications, such as for example the qualitative and quantitative measurement of certain waves in spectral measuring devices, especially for the analysis of the composition of materials.
- the present invention also relates to an image sensor device provided with an image acquisition device according to the invention, to a method of constructing a digital image by acquiring a panoramic anamorphic image at using an image acquisition device according to the invention, as well as a digital image obtained by the implementation of the image acquisition device according to the invention.
