Abstract

A device for capturing stereoscopic and non-stereoscopic video images. According to the invention, the particular (so-called tangential capture) position of the cameras which reduces the parallax angle and the diameter of the capture discontinuity area while enlarging the overlap area, helps obtain a higher quality live broadcast, a reduced post-production time and a distance to the filmed object that is also reduced. This particular orientation has a minimum space requirement without the cameras filming each other. The invention is intended in particular for imaging professionals.

Description

La présente invention concerne les dispositifs de capture d'images vidéo panoramiques, stéréoscopiques et non  The present invention relates to devices for capturing panoramic video images, stereoscopic and not

stéréoscopiques. Stereoscopic.

Parmi les différents moyens de capture de vidéos, la technique concernée par cette invention est celle de l'association par des techniques de "couture" numérique des vidéos enregistrées par des caméras observant en même temps devant, sur les côtés, à l'arrière, au dessus (zénith) et en dessous (nadir) d'un point de vue, Among the various means of capturing videos, the technique concerned by this invention is that of the association by digital "sewing" techniques of videos recorded by cameras observing at the same time in front of, on the sides, at the back, above (zenith) and below (nadir) from a point of view,

permettant de reconstituer une vidéo sphérique (complète ou non) appelée vidéo panoramique, de l'espace tout autour du point de vue. allowing to reconstitute a spherical video (complete or not) called panoramic video, of the space all around the point of view.

Lors du visionnage de ces images, le spectateur équipé d'un système de pilotage d'images, connu ( capteurs sensoriels, capteurs de mouvements, d'un casque spécifique, d'un joystick ou encore d'un clavier...) ou d'un système inconnu à ce jour, peut alors « parcourir » la sphère et visualiser la scène d'action sur 360°. During the viewing of these images, the viewer equipped with a known image control system (sensory sensors, motion sensors, a specific helmet, a joystick or a keyboard ...) or of an unknown system to date, can then "browse" the sphere and visualize the action scene on 360 °.

Les supports, appelés RIG 2D ou 3D, actuellement utilisés, quel que soit le type, le nombre, la taille et la disposition des caméras ne permettent pas d'obtenir des images d'une qualité suffisante pour les objets proches des caméras (notamment dans la zone de Media, called RIG 2D or 3D, currently used, regardless of the type, number, size and layout of the cameras do not provide images of sufficient quality for objects close to the cameras (especially in the zone of

"couture" entre deux caméras). "sewing" between two cameras).

Les logiciels de traitement de ces images, même avec une grande puissance de calcul de l'ordinateur effectuant l'analyse, ne pouvant corriger tous les défauts liés à cette technique. L'invention est caractérisée par la disposition des caméras dont les axes optiques sont tangentiels, disposition à encombrement minimal sans que les caméras se filment. Cette solution qui n'avait jamais été proposée améliore la qualité de l'image finale ? dans les zones de couture, grâce à la réduction de l'angle de The software for processing these images, even with great computing power of the computer performing the analysis, can not correct all defects related to this technique. The invention is characterized by the arrangement of cameras whose optical axes are tangential, minimum space requirement without the cameras filming. This solution that had never been proposed improves the quality of the final image? in the sewing areas, thanks to the reduced angle of

parallaxe et réduction du diamètre de la zone de discontinuité de capture, ainsi que l'accroissement de la zone de recouvrement.  parallax and reduction of the diameter of the capture discontinuity zone, as well as the increase of the area of overlap.

L'incidence négative de la différence de distance respective entre les caméras dont on associe les images avec le sujet étant0 mineure au regard de l'amélioration apportée par la réduction de l'angle de parallaxe. The negative impact of the respective difference in distance between the cameras whose images are associated with the subject is less than the improvement provided by the reduction of the parallax angle.

Le dispositif selon l'invention permet donc de réduire les problèmes de différences entre les deux images dans les zones de couture. Ce qui permet : The device according to the invention thus makes it possible to reduce the problems of differences between the two images in the sewing zones. Allowing :

- D'obtenir une diffusion en direct de meilleure qualité - To obtain a better quality live broadcast

- De réduire le temps de postproduction d'une image - To reduce the time of postproduction of an image

panoramique, en réduisant le temps nécessaire au traitement des zones de couture.  pan, reducing the time needed to process sewing areas.

- De fait, de permettre aux opérateurs de filmer des objets pluso près (l'incidence de la parallaxe entre les caméras étant fonction de la distance à l'objet) . Les dessins annexés illustrent l'invention : - In fact, to allow the operators to film objects moreo close (the incidence of the parallax between the cameras being a function of the distance to the object). The accompanying drawings illustrate the invention:

Les figures 1, 2, 3, 4, 5 représentent les caméras situées dans le volume dédié à la capture des images de devant, sur les côtés, à l'arrière ; elles démontrent les affirmations précédentes : Figures 1, 2, 3, 4, 5 show the cameras located in the volume dedicated to the capture of front images, on the sides, in the back; they demonstrate the preceding statements:

5 Fig 1 : pour des caméras en position autour d'une sphère, axe optique radial (positionnement habituel), mise en évidence de l'angle de parallaxe (bétal) à partir d'un point situé à 0m25 du centre du dispositif, du diamètre de la zone de discontinuité de capture d'images ( O 1) et de la zone de discontinuité de capture. 0 La figure 2 met en évidence, sur un exemple à 5 caméras (le nombre de caméra dépend de l'angle de champ de chacune d'elles), des caractéristiques du dispositif selon l'invention : FIG. 1: for cameras in position around a sphere, radial optical axis (usual positioning), highlighting the parallax angle (betal) from a point located at 0 m 25 from the center of the device, the diameter of the image capture discontinuity zone (O 1) and the capture discontinuity zone. FIG. 2 shows, on an example with 5 cameras (the number of cameras depends on the angle of view of each of them), characteristics of the device according to the invention:

45 L'angle de parallaxe ( béta2) et le diamètre de la zone de discontinuité de capture d'images ( 02) sont réduits de façon significative, concomitamment, la zone de recouvrement est nettement accrue. The parallax angle (beta2) and the diameter of the image capture discontinuity zone (O2) are significantly reduced, concomitantly, the overlap zone is significantly increased.

La figure 3 représente partiellement les systèmes existantsopour la capture 360° en 3D : les paires de FIG. 3 partially shows the existing systems for 3D 360 ° capture: the pairs of

caméras Cla/Clb, C2a/C2b sont installées côte à côte avec un léger angle de convergence ( alpha prime 1), disposées sur une sphère avec un axe optique radial de façon à occuper le moins de place possible. Le diamètre de la zone de discontinuité de lafcapture s'appelle 0primel, l'angle de parallaxe mesuré à la distance Rprimel est nomme béta prime 1. La figure 4 représente partiellement (2 paires sur un dispositif comprenant 6 paires) un exemple de l'invention. Les caméras Cla/Clb, C2a/C2b avec une convergence (alpha prime2) sont disposées avec un axe optique tangentiel à encombrementCla / Clb, C2a / C2b cameras are installed side by side with a slight convergence angle (alpha prime 1), arranged on a sphere with a radial optical axis so as to occupy as little space as possible. The diameter of the area of discontinuity of the map is called 0primel, the angle of parallax measured at the distance Rprimel is called beta prime 1. FIG. 4 partially represents (2 pairs on a device comprising 6 pairs) an example of the invention. The cameras Cla / Clb, C2a / C2b with a convergence (alpha prime2) are arranged with a tangential optical axis with congestion

F minimal sans qu'elles se filment. Comme pour la figure 3 l'angle de prise de vue est de 90°, les caméras sont de dimensions identiques, la comparaison met de nouveau en évidence que le rayon de la zone de discontinuité de capture 0prime2, tout comme l'angle de parallaxe béta prime2, sont inférieurs à leursMinimal F without filming. As for Figure 3 the angle of view is 90 °, the cameras are of identical dimensions, the comparison again shows that the radius of the capture discontinuity zone 0prime2, just like the angle of parallax beta prime2, are lower than their

^homologues de la figure 3. ^ homologues of Figure 3.

La figure 5 représente partiellement ( 2 paires sur un dispositif comprenant 6 paires ) un exemple de l'invention où les images des caméras sont réfléchies par des miroirs ou tout support présentant des caractéristiques optiques au moins égales à celle tfdes miroirs Ml et M2, les caméras Cla/Clb , C2a/C2b sont disposées avec un axe optique (après réflexion dans les miroirs) tangentiel (à encombrement minimal sans que les caméras se filment et décalées pour optimiser la capture indirecte des images). FIG. 5 partially represents (2 pairs on a device comprising 6 pairs) an example of the invention in which the images of the cameras are reflected by mirrors or any support having optical characteristics at least equal to that of the mirrors M1 and M2; Cla / Clb, C2a / C2b cameras are arranged with an optical axis (after reflection in the mirrors) tangential (with minimal space without the cameras are filmed and offset to optimize the indirect capture of images).
