Abstract

The system includes two cameras which are mounted side by side and spaced apart by a distance of 7 cm. The sensitivity of each camera in the spectral field is modified, either by the addition of a filter, or by control of colour amplification. The images gathered by the two cameras are directed towards a relay controlled by a pulse generator. This allows production of a train of images of duration 0.2 seconds, alternately from each camera. This produces a composite image giving a three dimensional effect. Colour selection can be based on selecting spectra with a bias either towards the ultraviolet end or infrared end of the spectrum.

Description

La présente invention concerne un dispositif pour appréander et restituer des images en 3 dimensions. The present invention relates to a device for learning and restoring images in 3 dimensions.

La restitution d'images en 3 dimensions nécessite traditionnellement l'uti lisation de matériels spécifiques à cette technique. The restitution of images in 3 dimensions traditionally requires the use of materials specific to this technique.

Le dispositif selon l'invention permet de remédier à cet inconvénient par la visualisation sans accessoires de l'image. The device according to the invention overcomes this drawback by viewing the image without accessories.

Partant du constat lors d'expérimentations personnelles que nos 2 yeux diffèrent en sensibilité dans l'analyse cnromatique du spectre visible, j'ai constaté personnellement une sensibilité plus grance en début de spectre (couleur rouge) pour l'oeil gaucne et l'inverse donc une sensibilité plus grande en fin de spectre (couleur bleue) pour l'oeil droit, ce constat établi m'a permi d'élaborer le dispositif dont il est fait mention ici. Starting from the observation during personal experiments that our 2 eyes differ in sensitivity in the cnromatic analysis of the visible spectrum, I personally noted a more gray sensitivity at the start of the spectrum (red color) for the left eye and vice versa. therefore a greater sensitivity at the end of the spectrum (blue color) for the right eye, this established observation allowed me to develop the device of which it is mentioned here.

Il est constitué de 2 caméras montées l'une à côté de l'autre et espacées de 7 cm ; écart senblable des yeux chez les etres humains. It consists of 2 cameras mounted one next to the other and spaced 7 cm apart; visible difference in the eyes in humans.

Chaque caméra sera supportée par un axe équipé de 2 roulements. Each camera will be supported by an axis equipped with 2 bearings.

La caméra de gauche par un artifice, filtre tTV où bien réglage des amplis couleurs sera rendue plus sensible en début du spectre visible (couleur rouge et aux couleurs voisines). The left camera by a device, tTV filter where fine adjustment of the color amplifiers will be made more sensitive at the start of the visible spectrum (red and neighboring colors).

La caméra de droite sera sensibilisée à la couleur bleue et aux couleurs voisines par l'adjonction d'un filtre bleu ciel où bien réglage des amplis couleurs. The camera on the right will be made aware of the color blue and the neighboring colors by adding a sky blue filter where the color amplifiers can be adjusted.

L'angle formé par l'axe optique des caméras sera variable et réglable à distance leur rotation sera rigoureusement parrallèle dans le plan vertical. Chaque axe comporte un engrenage, les 2 axes sont liés mécaniquement par ces 2 engrenages engrenant ensembles un moteur télécommandé muni d'un pignon assure la rotation commune des caméras entre elles. The angle formed by the optical axis of the cameras will be variable and adjustable remotely. Their rotation will be strictly parallel in the vertical plane. Each axis has a gear, the 2 axes are linked mechanically by these 2 gears, meshing together a remote-controlled motor provided with a pinion ensures the common rotation of the cameras between them.

Un écran de contrôle branché en aval au niveau de la restitution de l'image, permettra le réglage de l'angle optique entre les 2 cameras. A control screen connected downstream at the level of the image reproduction, will allow the adjustment of the optical angle between the 2 cameras.

Les images captées par les 2 caméras seront dirigées vers un relais commandé par un générateur d'impulsions qui nous permet d'obtenir un train d'images d'une durée de 0,2/s alternativement de chaque caméra. The images captured by the 2 cameras will be directed to a relay controlled by a pulse generator which allows us to obtain a train of images with a duration of 0.2 / s alternately from each camera.

Ces images d'une durée de 0,2/s nous situe au voisinage du décrochage de la perception visuelle des images, l'oeil gauche ne verra plus ou très peu ce que voit l'oeil droit et inversement, mais l'oeil gauche percevra la partie du sapez tre qui lui est favorable le rouge et les couleurs voisines, l'oeil droit pes cevra l'autre partie du spectre qui lui est favorable le bleu et les couleurs voisines, la zone centrale du spectre visible sera observée des 2 yeux avec la même sensibilité. These images with a duration of 0.2 / s situate us in the vicinity of the dropout of the visual perception of the images, the left eye will see little or no more what the right eye sees and vice versa, but the left eye will perceive the part of the sap tre which is favorable to him red and the neighboring colors, the right eye will weigh the other part of the spectrum which is favorable to him blue and the neighboring colors, the central zone of the visible spectrum will be observed from the 2 eyes with the same sensitivity.

Ces images sont alors disponibles comme les images traditionnelles entrées sur magnétoscope, télé vidéo, projecteur vidéo, liaison hertzienne etc...  These images are then available like the traditional images entered on a VCR, TV video, video projector, radio link, etc.
