Description

Title of the invention: Device, method and system for capturing anatomical images of an individual's head, as well as uses of said system Technical field of the invention

[0001] The present invention falls within the field of anatomical imaging of an individual and more specifically of capturing shots of an individual's head, in particular the face and hair.

[0002] It should be noted that the term “shots” includes images, such as photographs, or a successive sequence of images, such as a video, commonly referred to as “photo / video”.

[0003] The invention will find a preferential, but in no way limiting, application in the photo / video capture of the face or hair, for therapeutic, dermatological, cosmetic or aesthetic purposes, in particular for carrying out tests on the effectiveness of care products for facial skin or hair.

[0004] In this context, imaging of an individual's head involves a capture device that allows for different shots, such as photo / video, to be taken using a capture device, such as a camera or a photographic device. Such a capture device ensures the taking of photo / video shots, as well as their recording, in digital form, as files in photo / video format. In addition, the shots are taken in appropriate lighting conditions. These lighting conditions are determined by means of artificial lighting, with characteristics that depend on the desired goals. Such lighting can be standardized in wavelength (visible, IR, UV, specific wavelengths, etc.), in color temperature (variations of different daylight, artificial lighting, etc.), in polarization, and in geometry (specific direction of incidence, diffuse lighting, etc.). State of the art

[0005] Currently, a device for capturing shots of an individual's head, specifically targeting an individual's face, is described in particular in document FR 2 829 344. Such a capture device has a chassis on which a spherical reflector is mounted by assembling two half-spheres, with one located at the front provided with an opening for the passage of an individual's head. Two photographic capture devices, in the form of a camera, are positioned externally and integrally with the chassis, oriented towards the interior of the reflector via windows provided through the wall of the spherical reflector. Light sources are equipped with fiber optic lighting illuminating the internal walls of the sphere, with a determined light spectrum, in order to obtain a diffuse and uniform rendering of the light. Finally, this capture device provides colorimetric standards, positioned on supports located inside the sphere and designed to be mobile in rotation relative to said chassis. These standards allow the two cameras to be calibrated. Although such a capture device can diffuse light evenly, it remains limited due to the fixed lighting configuration and the fixed shooting points.

[0006] Another capture device comprises a frame provided with means for holding and positioning the head, in the form of a chin rest and a front support. This frame serves as a base for an open housing provided to be movable in rotation on said frame, by manual movement according to angular positions around said holding means. In addition, the housing is provided in its center with a capture device of the photographic camera type, positioned opposite the holding means. On either side of said device, the housing comprises lighting means, in the form of several light sources making it possible to illuminate the face with lights of types dedicated to the desired shot. A control means makes it possible to select the type of light. Such a capture device also includes means for digitizing the captured images, in particular allowing the generation of a three-dimensional digital model. While such a capture device allows for precise photographic shots of an individual's head, with dedicated lighting, it remains limited due to its configuration. Indeed, manually moving the housing according to determined and limited angular positions makes the configuration fixed during capture, prohibiting any form of movement. Furthermore, it does not allow video capture. In addition, the lighting is integral with the capture device, maintaining the orientation of the beams of the light sources in relation to the capture of said device.

[0007] Another known capture device further comprises a chassis with an internal housing provided with an oblong opening, sized to allow the introduction of the face of the head of an individual, with similar holding and positioning means, ensuring the holding of the head of the individual during capture. The housing has lighting means comprising light sources, of the white light LED type, distributed in groups along said wall. In addition, such a device comprises a capture device of the photographic camera type, positioned opposite the opening, halfway up the housing. This The device is fixed, requiring the user to turn their head to orient the corresponding part of the head facing the lens. Statement of the invention

[0008] The invention aims to overcome the drawbacks of the state of the art by proposing a device for capturing shots of an individual's head, with a distribution of the light sources along and around a concave wall of the housing receiving said head, forming a matrix screen. Such a matrix screen makes it possible to ensure specific lighting, by precisely modifying the lighting parameters in different areas of the concave wall. In addition, a window arranged longitudinally through the wall allows the capture device to be positioned between and set back from the light sources, avoiding the risk of shadowing, whether the capture device is fixed or mobile. In addition, a specific and planned control independent of the lighting of said light sources makes it possible to improve the lighting according to the shot to be taken, but also to reproduce with precision the capture parameters, in particular the parameters linked to the lighting. In fact, the lighting control allows vertical and / or horizontal scanning during capture, by lighting rows and / or columns of LEDs on the matrix screen.

[0015] According to additional, non-limiting characteristics, within such a capture method, the management comprises the steps of: - control the movement of said capture device between two angular positions; - control the lighting of said light sources according to each of the two angular positions of said capture device.

[0016] According to one embodiment, during the capture, the following is carried out: - a longitudinal scan around said housing by controlling the lighting of the columns; and / or - a vertical scan by controlling the lighting of the rows.

Detailed description

[0032] The present invention aims at taking anatomical views of the head 1 of an individual, in particular of the face and hair.

[0033] To this end, the invention relates to a device 2 for capturing anatomical views of the head 1.

[0034] Such a capture device 2 comprises a chassis 3. This chassis 3 serves as a base, as well as a support for the various elements of said device 2. According to the embodiment shown in Figures 1 and 2, the chassis 3 has a generally rectangular parallelepiped shape, with front, rear and side faces, as well as upper and lower faces.

[0035] Said chassis 3 is provided with an internal housing 4 with an opening 40 at least on the front face of said chassis 3, preferably on the front face and partly on the lower face. In addition, said internal housing 4 is sized to receive all or part of the head 1 of an individual through said opening 40. Consequently, the opening 40 is also sized for the passage of the head 1, preferably also an upper part of the bust via the lower face.

[0036] Further on, the device 2 further comprises a device 5 for capturing photo / video shots. This device 5 is mounted inside said chassis 3 and oriented towards the inside of said internal housing 4. In other words, the device 5 is located inside the chassis 3, namely within or outside the housing 4, and its lens is oriented so that its beam 50 captures the head 1 positioned within the housing 4.

[0037] It will be noted that the capture device 5 can be of any type, such as a photographic device or a camera, allowing the acquisition of shots, of photographic or video type. Said device 5 can allow the restitution but especially the recording of the shots, in photo / video format, preferably in the form of digital files.

[0038] The capture device 2 also comprises means 6 for illuminating said housing 4. In addition, said lighting means 6 comprise light sources 60, each having a light beam 61 oriented towards the interior of said housing 4. In other words, the light emitted by the sources 60 illuminates the interior of the housing 4. The light sources can be of any type, preferably in the form of LED (for “Light Emitting Diode”) or DEL (for “Electro Luminescent Diode”). The light sources 60 may also include means for emitting a specific beam, such as infrared and / or ultraviolet light.

[0039] Advantageously, said housing 4 comprises an inner wall 41 provided to be concave. In other words, the inner wall 41 of the housing 4 is rounded, forming a hollow and curved wall inside the chassis 3, in particular of generally semi-cylindrical shape. Such an exemplary embodiment is notably visible in Figures 1 and 2.

[0040] In addition, the lighting means 6 form at least one matrix screen of said light sources 60, distributed along and around said concave inner wall 41 of said housing 4. In other words, the light sources 60 are arranged according to a specific geometric configuration, on the surface of said concave inner wall 41. These sources 60 then form, alone or in combination, light pixels. For example, the matrix screen can be of the RGB (Red Green Blue) type, with groups of three light sources whose lighting combination makes it possible to obtain the entire visible light spectrum, namely all the colors. Preferably, the matrix screen is of the RGBW type (for “Red Green Blue White”), notably with groups of four light sources, in order to provide a better rendering of the light spectrum, in particular whites.

[0041] According to one embodiment, in particular when the light sources 60 are in the form of LEDs, said light sources 60 are distributed horizontally in rows and vertically in columns within said matrix screen, namely in an orthonormal reference frame. For example, the screen can then be of the OLED (for “Organic Light-Emiting Diode”) or DELO (for “Organic Light-Emitting Diode”) type. The said screen can also be of the LCD type (for “Liquid Crystal Display”), namely a liquid crystal screen. The said screen can also be a rigid or flexible panel, with the corresponding 60 light source technology.

[0042] According to one embodiment, the capture device 2 comprises means 7 for controlling the lighting means 6, in particular making it possible to independently control the lighting of each of said light sources 60, namely the LEDs of the screen. In other words, the control means 7 make it possible to turn on or off each light source 60, namely each LED, separately from the others. In short, the light sources 60 are controlled individually by the control means 7. These control means 7 make it possible to configure the parameters linked to the lighting, in particular, in a non-limiting manner, to modify the light intensity, the spectrum and / or the color of each of said light sources 60. It will be noted that the control means 7 make it possible to record and store said parameters, in order to reproduce them in a similar or identical manner.

[0043] According to one embodiment, the control means 7 ensure the lighting of at least one of the rows and / or at least one of the columns of said LEDs. Preferably, the control means 7 ensure the lighting of several rows and / or several columns at a given time. It should be noted that, as the 60 light sources are controlled independently, it is possible to carry out lighting in an inclined or diagonal manner, or even by groups of LEDs of different geometric shapes. According to one embodiment, the control means 7 make it possible to turn on and then off one or more rows (and / or columns) at successive time intervals, so as to perform a horizontal (and / or vertical) scan, from the top to the bottom (and / or from the left to the right) of the screen, or vice versa.

[0044] According to one embodiment, the capture device 5 is positioned inside the housing 4, as close as possible to said concave interior wall 41. In this configuration, said capture device 5 may be of restricted dimensions, such as a mini-camera. According to a preferred embodiment, the concave interior wall 41 is provided with a window 42 arranged longitudinally between said light sources 60. Said window 42 therefore provides a space between the rows. In addition, said capture device 5 is mounted at the rear of said concave inner wall 41 and is directed through said window 42, namely that its objective is located relative to the housing 4 behind the concave inner wall 41, the window 42 allowing the beam 50 to penetrate into the housing 4 for the purpose of capturing the shots. Such a configuration makes it possible to install within the volume of the chassis 3 located at the rear of the inner wall 41 of the housing 4, a device 5 with advanced characteristics, in particular a better quality objective, with larger dimensions or any other characteristic, thereby improving the quality of the shots. According to a preferred embodiment, as visible in Figures 1 and 2, the window 42 extends horizontally, from one vertical edge to the other of the concave interior wall 41. Thus, it is possible to position the capture device 5 at a location of the window 42, according to an angular position around the concave interior wall 41 of the housing 4, in order to orient its capture beam 50 according to a determined angle, to acquire a chosen part of the face of the head 1 of the individual. For example, the device 5 can be positioned to capture each profile and front view. Furthermore, thus positioned set back from the screen, said capture device 5 does not in any way disturb the lighting of the head 1, generating no shadowing or occultation of the lighting.

[0045] According to one embodiment, said capture apparatus 5 is mounted to move along said concave inner wall 41, preferably in a horizontal direction in the corresponding embodiment where said window 42 extends in this direction. Therefore, the apparatus 5 can be moved into angular positions along the concave inner wall 41 of said housing 4.

[0046] According to one embodiment, as visible in [Fig.2], the capture device 2 comprises a support, at the end of which said capture apparatus 5 is mounted. Said support has a square shape, with a vertical arm connected to a horizontal arm, one end of which is secured to rotational motorization means. The apparatus 5 is mounted at the distal end of said vertical arm. Therefore, such a support 52 provided to rotate, makes it possible to ensure the maintenance of the apparatus 5 in an offset manner inside the chassis 3, along the concave interior wall 41 and opposite the window 42, as well as to transmit the horizontal rotation movement, following a trajectory opposite said window 42.

[0047] Furthermore, the capture device 2 further comprises means for controlling the movement of said apparatus 5. In other words, the control means make it possible to move the apparatus 5 from one position to another around said housing 4. They can also control the speed of movement of the apparatus 5. In a related manner, the triggering of the shots by the device 5 can be executed from dedicated means, preferably through said control means. Relatedly, the control means may allow for controlling the capture parameters of the device 5, such as the zoom degree, focal length, shutter time, exposure, etc. According to one embodiment, such control means can be combined with the lighting control means 7. The example of [Fig.5] shows control means 7 for controlling the angular position and the movements of the apparatus 5, as well as the lighting of the light sources 60 according to rows and according to columns. For example, the control means and the command means 7 may be software running on a computer terminal, in particular a computer or tablet type.

[0048] Therefore, according to a corresponding embodiment, the control means 7 ensure the illumination of at least one of said light sources 60, namely one or more LEDs, preferably one or more rows (and / or one or more columns) of the LEDs, depending on at least one of the angular positions of said capture device 5.

[0049] Thus, the control means 7 make it possible to configure and reproduce a determined lighting, for each position of the device 5, in order to obtain optimized shots.

[0050] The invention also relates to a method for capturing anatomical views of the head 1 of an individual. According to one embodiment, such a capture method ensures the implementation of the capture device 1, as previously described.

[0051] Further, this capture method comprises at least the following steps. First, an individual positions his head 1 at least partly inside a housing 4 provided with a concave internal wall 41. On the one hand, this wall 41 is equipped with lighting means 6 provided with several light sources 60. In addition, these light sources 60 are distributed in rows and columns forming a matrix screen along said concave internal wall 41 of said housing 4, On the other hand, said concave internal wall 41 is equipped with a device 5 for capturing photo / video shots. This device 5 is designed to be movable in horizontal movement according to at least one angular position around said housing 4, along a window 42 arranged longitudinally between said light sources 60.

[0052] Further on, a photo / video shot is captured using said device 5 at each angular position, by performing controlled lighting of at least one area of ​​the head 1. As mentioned above, head area 1 can be the face or hair, but also a more specific anatomical part, such as the cheek, eyes, eyelids, etc. The example in [Fig.3] shows side lighting, from the left, while the device 5 is positioned in the center of the housing 4. The example in [Fig.4] shows illumination of the chin of head 1, while the device 5 is positioned in the center of the housing 4, opposite the face. It should be noted that the lighting control can reside in the parameterization of characteristics of the light sources, as previously mentioned.

[0053] Advantageously, the capture method provides that during said capture, lighting management is carried out independently of each of said light sources 60, at least as a function of each angular position. In other words, the lighting of one or more LEDs is controlled, relative to the targeted area of ​​the head 1 to be illuminated, as well as relative to the position of the device 5, or the successive positions of said device 5. According to one embodiment, the capture method provides that the management comprises controlling the movement of said capture device 5 between two angular positions. In other words, the control makes it possible to move the device 5 along the window 42 according to several successive positions, by choosing its speed. In addition, the management makes it possible to control the lighting of said light sources 60 as a function of each of the two angular positions of said capture device 5.

[0054] According to one embodiment, the capture method provides that during the capture, a longitudinal scan is carried out around said housing 4 by controlling the lighting of the columns; and / or a vertical scan is carried out by controlling the lighting of the rows. The example of [Fig.6] shows a horizontal scan from left to right, controlling the lighting of groups of several columns of the light sources 60, by successively switching on and off said groups. In addition, the apparatus 5 is controlled in movement according to a corresponding horizontal translation, in order to follow the lighting provided by such a horizontal scan. The example in [Fig.7] shows a horizontal scan from left to right, controlling the illumination of groups of several columns of the light sources 60, while the device 5 remains fixed. The example of [Fig.8] shows a vertical scan from top to bottom, controlling the lighting of groups of several rows of light sources 60, by successively switching on and off said groups. In this case, the device 5 can be fixed or moved. For example, a group of three rows can be lit and then a next row is lit while the first row of said group is unlit, and so on. Additionally, it is possible to control the light intensity to create a fade, gradually decreasing the brightness of one or more rows, while gradually increasing the brightness of one or more subsequent rows, to smooth out the apparent light movement thus generated. The example in [Fig.9] shows a capture of shots of the back of an individual's head 1, preferably their hair. The lighting is then controlled according to several adjacent columns (and consequently, also all the light sources 60 in the rows at the intersection of the columns). This successive lighting of the 60 sources per row and / or column allows for mobile lighting, simulating a movement of the light sources, which are nevertheless fixed.

[0055] According to one embodiment, the capture method provides that during the capture, the characteristics of the lighting are controlled, preferably the light intensity, the spectrum and / or the color of each of said sources 60 lu- miners.

[0056] In a related manner, the aforementioned capture method may involve control means 7, similar or identical to those of the capture device 1.

[0057] The invention also relates to a system for capturing anatomical views of the head 1 of an individual.

[0058] Such a system is intended to essentially ensure the processing of the shots captured according to the capture method as previously described.

[0059] To do this, the capture system plans to record the captured shots in digital format in the form of photo / video files, with capture parameters for each of said shots. As mentioned above, the capture parameters may include the lighting parameters (such as the light intensity, spectrum and / or color of each of said light sources), but also the position(s) of the device during the capture, as well as its speed of movement between the positions, and especially the characteristics of the lighting at each of said positions. As mentioned above, all parameter data can be recorded, in order to reproduce identically or similarly the lighting and positioning of the capture device 5.

[0060] Further on, computer processing of the files is carried out, using software executed on a computer terminal, in particular in the form of a computer or a tablet. Advantageously, the capture system provides that said processing consists at least of comparing the files of at least two shots with similar parameters and captured at different times and, preferably, several days apart.

[0061] According to one embodiment, said processing consists of generating a three-dimensional digital model of the head 1 of said individual. It is then this model which can serve as a comparison. The generation of such a three-dimensional model can be performed by any known software means. According to one embodiment, said processing consists of generating a three-dimensional digital model of the face and / or hair.

[0062] The invention also relates to the use of the aforementioned capture system. A first use can be for diagnostic, therapeutic or aesthetic monitoring of a substance, in particular medical or cosmetic, applied to the captured area of ​​the head 1. It should be noted that such use may involve the interpretation of a practitioner or specialist in the corresponding field. For example, it could be a dermal cream or makeup product applied to all or part of the face. Several captures are then taken several days apart, in order to determine and identify the effects of said cream or makeup on the skin. Regarding hair, this could involve checking the effects of a substance, such as a shampoo, or monitoring the progress of a scalp and / or hair treatment.

[0063] According to different embodiments, the invention provides the use of the capture system for the visualization and characterization of different captured anatomical parts, with respect to criteria determined as a function of said corresponding anatomical part. Furthermore, the characterization can be carried out according to predetermined scales, with different degrees or steps. It is then possible to visualize from the captured images, in particular between two time intervals, and to compare one or more characteristics of the captured anatomical part with said scales. This may be used for the visualization and characterization of the skin, namely the epidermis (or even the dermis), such as color, homogeneity, the presence of wrinkles, pores, spots and / or dark circles, or even lesions of any type. Another use is intended for visualization and characterization of the face, such as shape, facial contour, volumes, morphological criteria and / or morphological deformations. Another use is intended for visualizing and characterizing hair, such as color, shine, highlights, length, density, alignment, volume, and / or movement of the hair. Another use is planned for the visualization and characterization of the effects of hair products, such as color or coloring, or even the rendering (e.g., reflections) under different brightnesses, or even the hold over time. Another use is intended for the visualization and characterization of the effects of makeup products, such as hold, homogenizing effects, the degree of masking of skin imperfections, mattifying effects. Such makeup products may be, but are not limited to: foundations, lipsticks, eyeshadows or mattifying creams. Another use is provided for the visualization and characterization of makeup products with particular optical effects, such as products containing pigments, particularly goniochromatic pigments, glitter or iridescent effects.

[0064] According to other embodiments, the invention provides the use of the capture system for visualizing and characterizing the effects of different cosmetic products, such as products aimed at improving the aesthetics of the skin, “anti-aging” products, makeup products and / or makeup remover products. This may involve visualizing and characterizing skin shine, pore visibility, skin texture, dark circles, skin smoothing, a reduction in imperfections, or even a reduction in the visibility of pigment spots, wrinkles (dimensions and depth), ptosis, facial contour. It may also involve detecting the presence of makeup product residue on the skin after makeup removal. According to other embodiments, the invention provides for the use of the capture system for visualization and diagnosis, as well as therapeutic monitoring targeting said captured anatomical part, in particular the skin, or even hair implantation. Such a diagnosis may include therapeutic monitoring, in particular before and after the performance of an aesthetic procedure, for example: injections, facelift, reconstructive surgery, or even filling of wrinkles, smoothing / plumping effect, modification of the shape of the nose. One use also aims at the visualization and characterization of dermatological treatments, such as acne, vitiligo, melasma or psoriasis.
