The invention relates to a device for taking pictures of an object so as to reproduce it in three dimensions on a display screen.

This type of device is particularly known for viewing an object and adorning accessories to provide a rendering of this object as it could be in reality.

An example of application is the customization of spectacle frames.

For this purpose, the US2003 / 0206735 US patent application describes a device for including simulating the wearing of glasses by a person or viewing the frame with all types of glass or provided with accessories such as jewelry.

The device used in this document comprises a box provided with lighting, a support for an eyeglass frame, means for rotating the support in order to position it at different fixed stations according to, for example, successive angles of 90.degree. , a camera taking pictures for each of the fixed stations of the medium, and means for exporting the photographed images to a computer for processing for viewing the mount on the computer.

However, this device makes it possible to view the frame only in successive different postures, having an isolated image on the screen of a view for example exclusively from the front and then a side view. Gold, we still want to change this visualization by making it more attractive and real, especially in its application at opticians to help customers in their choice of frames and accessories.

The object of the invention is therefore to provide a device that meets these three-dimensional viewing requirements of the object.

The invention will be more particularly described with regard to an application for spectacle frames, without being limited thereto, the object to be displayed being of any type, and in particular relating to leather goods, shoes, jewelery.

According to the invention, the device for taking pictures of an object for its display on a screen comprises a housing, preferably closed over its entire periphery when taking pictures, lighting, a support for said object, means for taking pictures of the object, means for transmitting the information of the shots to processing means, and is characterized in that the recording means comprise, according to a first embodiment, at least two video cameras arranged in a fixed manner while the support is able to be rotatable 360 °, or according to a second embodiment, at least one camera adapted to be rotatable about the object.

Such a device makes it possible to provide a three-dimensional image of the entire object in order to visualize it on a screen, in space and to be able to rotate it, giving a particularly real rendering of the object to an object. observer. Dynamic and continuous shots provide a particularly real-world rendering, the object being orientable in all directions of space, and viewable from all angles.

Advantageously, the device also constitutes a sound recording device, and in that the housing is acoustic including sound insulation coatings.

According to the first embodiment, a first camera is arranged above the object and a second camera is arranged laterally to the object.

In this embodiment, the device comprises means for adjusting the support vis-à-vis the horizontal and vertical axes of sight of each camera. It is important that the object is correctly centered with respect to the camera for the quality of the image to be obtained in three dimensions.

Advantageously, the device comprises a third camera positioned under the object.

According to the second embodiment, the camera moves around the object according to 360 °, in a median and vertical plane of the object on the one hand, and in a median and horizontal plane of the object

Also, for one or other of the embodiments, the device comprises means for rotating the support or cameras to film the object 360 °.

Preferably, the rotation means are controlled by electronic means. According to a characteristic and an exemplary embodiment, the illumination comprises a plurality of spots or fluorescent tubes, the arrangement of which in the housing provides homogeneous illumination and without shadow, preferably in an arrangement in planes inclined at 45 ° by compared to the walls of the case

According to another characteristic, the support has a shape adapted to support the object.

The device is intended to be connected to processing means and a display screen for providing the screen with a three-dimensional image of the object and intended to be rotated.

The object is for example applied to a spectacle frame.

Whatever the type of object, the device is thus used for the personalization of the object by accessories and the on-screen display of the latter with accessories.

The invention also relates to an assembly comprising the device according to any one of the preceding claims and a display screen, characterized in that the screen has means of interactivity between the observer and the object displayed at screen to provide it with accessories. The observer, such as a customer wishing to purchase the object, can therefore virtually customize and sign said object by giving it the desired appearance on the screen and visualizing it in three dimensions while rotating it in the 'space. By rendering the accessorized object on the screen, as it would in reality, the client makes sure of his choice. Finally, the invention relates to a method of personalizing an object, of the optical mount type, from the device described above, comprising the steps of: placing the frame on a support inside the closed housing , take a 360-degree video camera, process all the information taken by the camera (s), - visualize the object in three dimensions on a screen and dress it up using computerized means of accessories visualized on said screen.

- Figure 16Bis is a longitudinal sectional view of Figure 16.

FIG. 1 illustrates a device of the invention, applied by way of example to the on-screen display of a personalized spectacle frame by optical glasses, possibly solar, and of aesthetic elements that the observer (the client when the device is used in an optical shop) will be able to choose. The customer can thus select the desired accessories (type, color, shape) and virtually visualize his mount tree of said accessories, under whatever angle of vision whatsoever.

The device visible in FIGS. 1 to 5 a comprises a housing 1, preferably parallelepipedal, intended to receive the object to be treated such as a spectacle frame 1 1, a support 20 for depositing the object, means

15 of the rotation of the support 20, the lighting means 10, the camera means 9, the transmission means 6 and 7 of the information transmitted by the shooting means to a computer comprising a software adapted to the processing of the information . By "treating the object" is meant all the operations consisting in filming and scanning the frame, sending the shooting data to the computer processing means equipped with a specific software, and viewing the frame on a screen. computer science.

The housing 1 has an opening at one of its sides and closed by a removable or movable cover 2. This opening allows access to the interior of the housing to introduce the object and remove after the shots. Figure 1 illustrates the housing in the closed position, while the latter is in the open position in Figure 2.

The opening is arranged in the upper part of the housing for easy access but could be on another side, for example laterally when the housing is placed horizontally. Access will in fact be adapted according to, in particular, the type of application or object, or location of the device within a store for example. In addition, depending on the type of camera, and when a camera is placed at the top of the housing, it may be more convenient to provide lateral access for the stability of the camera.

The dimensions of the housing are adapted according to the application and therefore the object to be treated.

The housing is advantageously provided with microphones which are for example associated with the shooting means 9. These microphones make it possible to record sounds, of the music or lyrics type (comments for example), which are elaborated during the shots of the camera. 'object. Indeed, as will be seen later, the means of shooting consisting of video cameras, the possibility of adding a speaker to the housing for send sound when shooting the camera with which a microphone is integrated, allows when viewing on the screen of the object to associate a sound reproduction. Similarly, if the object to be viewed emits sounds, the camera allows to record and retransmit when viewing the object.

Preferably, a directional microphone will be used as well as a headset providing the exact return of the recorded sound in order to know the sound that will be established when viewing the object on the screen.

In addition, the housing at its walls is advantageously acoustic to provide an optimal recording sound. Moreover, the materials constituting the housing will be particularly insulating to prevent the transmission of noise from the outside to the inside of the housing. In particular, it will be ensured that the noise of the means ensuring the rotation of the support 20 are not perceived and / or recorded.

The support 20 of the object to be treated has a shape adapted to the object to be treated. It may be a simple tray, or as here and as illustrated in Figures 4, 4Bis, and 4Ter, a tray or base 8, on which is secured to a vertical rod 17, to end of which extends in a horizontal plane and in the form of T, a horizontal rod 14 and a rod 15 transverse thereto. The free end 13 of the rod 14 is the nose support of the frame, while the rod 15 is the rest-branches of the frame.

The support 20, or here the vertical rod 1 1 carrying the rods 14 and 15, is intended to rotate when taking pictures. According to the invention, the means for the rotation of the support provide 360 ° continuous rotation, while the shooting means 9 are in operation. The rotation is carried out for example by means of a motor 16 (FIG. 4 ter) acting on the rotation of the vertical rod 1 1.

The means are controlled by electronic control means, and in particular under the control of the same software that provides the processing of the shooting information. The software manages the rotation of the support and its stop.

The illumination 10 is designed to provide the interior of the housing a harmonious, homogeneous light without shadows, and avoid light reflection of the object towards the means of shooting 9, so as to optimize the color rendition and details of the object.

For example, as illustrated in Figures 5 and 5a, the illumination is composed of a plurality of spots, four in number, S1, S2, S3 and S4 which are advantageously positioned. The spots are here arranged on inclined planes at 45 ° with respect to the walls of the housing so that the residual reflections generated from the illuminated mount are not in the field of view of the imaging means 9.

Alternatively, the light may include fluorescent tubes rated at 6500 ⁰ K.

According to the invention, the shooting means 9 consist of at least two video cameras (FIG. 5bis), a camera 9A being arranged vertically of the object to take top views, while another camera 9B is located in a transverse and horizontal plane to take views of the whole object that turns on itself from 0 to 360 °. The camera 9A vertically of the object belongs to the plane of the upper part of the housing, while the 9B is arranged in the plane of one of the side walls of the housing. The use of miniaturized cameras makes it possible to integrate the camera 9A to the housing cover when the latter is in the upper part. The camera 9A to be in the upper part of the housing, it is always possible to provide the opening of the housing rather on a side wall.

The camera 9B providing peripheral vision of the object requires centering the object with the vertical and horizontal axes of the camera. For this purpose, the support 20 comprises adjustment means 5 in height (FIGS.

3 and 4) and adjusting means 12 in the horizontal plane of the camera

(Figure 3). These adjustment means are, for example, knurls. They are actuated when the support 20 of the object is in a fixed position and the object is on its support.

Thus, the wheel 5 makes it possible to adjust the height of the frame 1 1 so that the median axis and passing through the front face of the frame is aligned with the horizontal axis of the camera. The wheel 12, for its part, guarantees positioning of the face of the frame in a plane parallel to the fixed viewing plane of the camera.

In addition, it is conceivable to add a third camera arranged below the object and the opposite of the camera 9A vertical, in which case the support of the object must be transparent.

In an alternative embodiment of the invention illustrated in FIG. 5 ter, instead of having at least two fixed cameras and a rotatable support 20, the device comprises only one camera 9 able to rotate around the camera. object whose support remains fixed. The camera turns successively around the object following a circle arranged in a median and vertical plane of the object using guide means 90, then in a circle arranged in a median and horizontal plane of the object with the aid of guide means 91.

The shots taken by the cameras are transmitted by the communication means 6 and 7 (cable and USB port) to a computer constituting the data processing means and equipped with specific software that reproduces an image by three dimensions able to be rotated.

The processing means also incorporate a catalog of accessories of the decorative type. The accessory chosen by the customer will be by the processing means merged with the treated object to view the set on computer screen.

The client (the observer of the screen) can interactively develop on the screen, visualizations of the object according to his choice of accessories.

Also, means internal to the computer to display on the screen, as shown in Figures 6 to 14, icons guiding the observer in his choices and described in more detail later.

The implementation of the device of the invention is hereinafter described.

After choosing the client for an optical or solar mount, the optician offers a customization of this equipment. It opens the housing cover 1, positions as shown in Figures 4, 4Bis and 4Ter, the mount on the support 20, more particularly the nose of the mount on the nose rest 13 and the branches on the rest branches 15 glasses. It closes the cover 2 of the housing to completely close the housing.

By pressing the button 3 "on" of the housing (Figure 1), the lighting 10 is turned on to illuminate the mount smoothly and uniformly avoiding any shadow areas. The "on" function for operating the device can of course also be accessible from computer tools, for example by clicking on an icon located on the computer screen.

Then the 360 ° rotation of the frame is triggered in combination with the operation of the cameras. The entire frame, seen from above and 360 °, is taken according to continuous images by the cameras. The cycle can be interrupted at any time by pressing button 4 "off" of the housing. Alternatively, this feature could be made accessible directly from the computer screen, for example by clicking on the screen icon.

When the 360 ° rotation cycle is completed, all the information is transmitted via the computer cord 6 to the USB port 7 of a computer.

The observer can then view on the screen the frame and customize accessories from icons installed on the screen.

For example, the observer may wish to customize optical and solar glasses, this customization will be at the level of frames and ophthalmic lenses. A first icon, says Id and not shown here, allows clicking on it to rotate on the screen, the frame 360 °.

Four icons will be available (Figure 6, BD, FD, FG, BG references) depending on which part the observer wishes to customize. By clicking on the BD icon, you only get the outer right branch of the frame (Figure 7). By clicking on the FD icon, we get the right half of the face of the mount (Figure 8). Clicking on the FG icon gives the left half of the frame (Figure 9). Finally clicking on the BG icon, we only get the outer left branch (figurel 0).

Then, choose an accessory. As illustrated in Figure 11, a task bar is at the bottom of the screen being composed of several icons each of which determines a type of decorative object (jewelry ...).

The accessories are various, as examples, rhinestones, flowers rhinestones or various metal (gold, silver ...), stars in rhinestones or various metal (gold, silver ...), initial rhinestones or in various metals (gold, silver, etc.), cultured pearls, cutouts in ophthalmic or solar glasses, glitter on ophthalmic lenses, degraded or biodegraded solid shades on ophthalmic lenses.

After choosing an accessory icon, for example "rhinestone icon", we access a window (Figure 12) showing the different colors and sizes of the accessory. By choosing a color and a size of rhinestones, we return to the visualization of Figure 1 1, which is positioned at the desired location of the frame, with the mouse of the computer or a computer optical pen, the selected rhinestone (view of Figure 13). At any time, if we want to have an overview of the result as a whole illustrated in Figure 14 and corresponding to the three-dimensional image of the frame with its accessories, press the "ok" button on the screen.

The "code" box illustrated on the screen in FIG. 6 serves to record a previously treated frame which is for example often requested by the customers. The mount, once treated, is integrated and stored in a computer catalog that it is possible to browse without having for this specific frame to retreat the frame when a customer wants to view it.

Once the accessory identified, such as a jewel, and the positioning of this accessory on the mount, the optician will then realize the mount in his workshop.

Two methods of fixing jewelry on ophthalmic lenses and frames are discussed below, these processes being of commercial and industrial interest.

The first method of fixation on ophthalmic lenses is as follows:

The jewel is fixed by welding on a metal rod called ankle. This rod is positioned on the front face of the organic ophthalmic lens and is pressed into the glass. The metal rod passes through the thickness of the organic ophthalmic glass because the latter material has the physical property of easily piercing.

Maintaining the jewel on the ophthalmic surface is through a T-shaped plastic socket at the back of the glass (Figures 16 and 16Bis). The pressure between the jewel and the plastic sleeve will prevent any loosening.

The second method of fixation on ophthalmic lenses is as follows:

The jewel is fixed by welding on a threaded metal rod while being positioned on the front face of the organic ophthalmic lens. Again, the threaded metal rod passes through the thickness of the organic ophthalmic lens because the latter material has the physical property of piercing. The maintenance of the jewel on the ophthalmic surface is done by a nut at the rear face of the glass (Figures 15 and 15Bis).

Depending on the choice of the frame, the lenses can be classified according to three families: - beveled lenses, for rimmed fixtures, ice lenses for drilled fixtures, grooved lenses for frameless fixtures called "nylor".

The jewel is positioned on the front side of the organic ophthalmic lens. This position is determined by the client, favoring the peripheries of the upper and lower temporal nasal glass. The central zones are devoid of jewels, because they are intended to correct the defects of the vision; these areas must keep their transparency as well as their optical properties.

The principle of the jewel welded on a metal peg rod or a threaded metal rod can likewise be positioned on the outer face of the branches of the spectacle frames because the materials of these frames are pierceable whether they are acetate plastic, or metal, etc .... The same process as for fixing jewelry on ophthalmic lenses, is envisaged at the inner face of the glasses branch: a plastic sleeve or a nut is used to maintain the jewel.

The potentiality of harmonization between the jewel situated either at the level of the front face of the organic ophthalmic lens, or on the outer surface of the branches of the spectacles with respect to the other levels, ie the ears (earrings) and the neck (necklaces) generates a dynamic of change.

The glasses are no longer fixed, they evolve to the taste of each, according to the desired aesthetic, depending on the situation and time, depending on the style of the person. At any moment, the person can complete, harmonize his mount by developing his choices and previewing the rendering on screen.
