Description

"AUGMENTED REALITY MAGNIFIER EYEWEAR."
DESCRIPTION
TECHNICAL FIELD OF THE INVENTION
The present invention relates to augmented reality magnifier eyewear, otherwise known in the sector by the term "smart loupes". More particularly, the eyewear of the present invention comprises: a frame, two screens mounted on said frame, a first screen being mounted at the right eye of the user of the eyewear and a second screen being mounted at the left eye of the user, a camera, or a video camera for acquiring images of the working field, positioned in the median point of the frontal portion of the frame; an electronic unit configured to receive in input said at least one digital image. The electronic unit is configured to divide said at least one digital image of the working field into a digital image of the right hemifield of the working field to be sent to one of the two screens and a digital image of the left hemifield of the working field to be sent to the other screen. The electronic unit can also act as interface with an augmented reality engine capable of sending data to said electronic unit. The latter in turn can overlay these data on one or on both of the images displayed on the screens. The possibility of interfacing with systems for augmented reality may be of particular interest in the diagnostic or surgical field. In these fields, it is of considerable utility to overlay on enlarged images both alphanumerical information related, for example, to vital parameters (e.g. blood pressure, heart rate, oxygen saturation, etc.), and medical digital images previously acquired with different imaging techniques, such as for example magnetic resonance imaging (MRI) and computed tomography (CT). In the field of dentistry, on the other hand, the use of augmented reality in magnifier eyewear can be relevant in the programming and in the execution of operations for the insertion of osseointegrated implants, where the integration of images acquired in real time from the monocle with CT - Dental Scan images can be useful. Finally, the integration may also be of interest of the acquired images with diagnostic information obtained through appropriate deep learning algorithms applied to the same images acquired, in real time, by the camera forming part of the eyewear. An example of the application of the latter type of integration can be the evaluation of skin melanomas through the visualization of graphic contouring and a textual indication overlaid on the actual image of the melanoma.
STATE OF THE ART
As mentioned above, magnifier eyewear, preferably, but not exclusively, for medical and dental purposes is a very widespread product in the world. The general purpose of magnifier eyewear is to magnify a portion of the field of vision of operation, at a working distance, usually fixed, bringing this portion into the user's field of vision and into the natural position of near vision.
At the current state of the art, two main types of magnifier eyewear are known. More particularly, in the first type, also known by the term "FlipUp", the magnifier devices are mounted on a support structure that is adjustable and rotatable. In the second type, also known by the term "Through the Lens", the magnifier devices are, instead, glued inside special holes applied to the carrier lenses.
The magnifier eyewear solutions widespread on the market are equipped with digital screens connected to at least two photographic cameras/ video cameras fixed, directly or indirectly (i.e. by means of the lenses), on the frame of the eyewear. Some examples of these solutions can be found in prior art documents US20150123880A1, EP1884819A1. The US application US20150123880A1 and the European application EP1884819A1 both describe magnifier eyewear for medical use equipped with two video cameras and two digital screens. The video cameras and the screens are not integrated into a single device. The screens are, in fact, positioned separately from the video cameras and are connected to the frame in US20150123880A1 and to the carrier lenses in EP1884819A1. In these solutions and, in particular, in US20150123880A1, the video cameras are in an external position with respect to the temples of the frame with the consequent and inevitable generation of parallax errors with respect to the human eye. OBJECTS AND SUMMARY OF THE INVENTION
The object of the present invention is, therefore, to avoid parallax errors being generated due to the difference between the localization of human eyes with respect to eyewear and the positioning of the video cameras on said eyewear.
This object is achieved by the present invention thanks to the use of a single video camera positioned centrally on the eyewear. For the purposes of this description, the expression "centrally positioned" is intended to mean that the video camera or photographic camera is positioned at the median point of the frontal portion of the frame, i.e. in the middle of the two lenses in the case of eyewear of the Through the Lens type. The eyewear of the present invention comprises, moreover, an electronic unit configured to receive in input the images acquired by the photographic camera/ video camera and to divide them into two images corresponding to the two left and right halves of the working field represented by the image. In other words, the images of the working field of the eyewear user are captured and enlarged by the central photographic camera/ video camera and then divided into a first image of the left hemifield of the working field and into a second image of the right hemifield of the working field. The first image is then sent to a first screen, of the organic light-emitting diode type, or OLED screen, positioned at the left eye of the user, and the second image is sent to a second screen, always of the same type, positioned at the right eye of the user, thus reconstructing the illusion of a stereoscopic image.
More particularly, in the case of eyewear of the FlipUp type, the present invention relates to magnifier eyewear comprising:
• a frame comprising a frontal portion;
• a first organic light-emitting diode screen mounted on said frontal portion;
• a second organic light-emitting diode screen mounted on said frontal portion;
• a digital photographic camera configured for the acquisition and the enlargement of at least one digital image of a working field of a user of said eyewear or a digital video camera configured for the acquisition of at least one time sequence comprising at least one digital image of a working field of a user of said eyewear and for the enlargement of the at least one digital image of the working field; and
• an electronic unit configured to receive in input said at least one digital image. In the case instead of eyewear of the Through the Lens type, the present invention relates to magnifier eyewear comprising:
• a frame comprising a frontal portion;
• a first lens and a second lens, said lenses being mounted on said frontal portion;
• a first organic light-emitting diode screen mounted on said frontal portion, parallel to said first lens;
• a second organic light-emitting diode screen, mounted on said frontal portion, parallel to said second lens;
• a digital photographic camera configured for the acquisition and enlargement of at least one digital image of a working field of a user of said eyewear or a digital video camera configured for the acquisition of at least one time sequence comprising at least one digital image of a working field of a user of said eyewear and for the enlargement of the at least one digital image of the working field; and
• an electronic unit configured to receive in input said at least one digital image.
It is obvious that in the Through the Lens type the screens can also be mounted directly on the lenses. Since the latter are mounted on the frame, in this case the screens have the feature of being mounted on the frame even if indirectly.
For the purposes of the present description, therefore, when it is stated that the screens are mounted on the frame, it is intended to comprise both the case of the FlipUp configuration, in which there are no lenses and the screens are mounted on the frame, and the case of the Through the Lens configuration, in which although the lenses are present, the screens are mounted not on the lenses, but directly on the frame. Stating that the screens are mounted on the frame comprises, finally, the case of the Through the Lens configuration, in which the screens are mounted on the lens and, therefore, only indirectly on the frame.
In both configurations the photographic camera, or the video camera, is positioned at the median point of the frontal portion and the electronic unit is configured to divide said at least one digital image of the working field into:
- a digital image of the left hemifield of the working field to be sent to the first screen; and
- a digital image of the right hemifield of the working field to be sent to the second screen.
Thanks to the central position of the photographic camera, or video camera, the parallax error is cancelled in that the photographic camera, or video camera, is positioned exactly in the optical axis of the system.
A second object of the present invention is, then, to provide magnifier eyewear in which it is possible to dynamically vary the working distances and enlargements taken by the photographic camera, or video camera.
This object is achieved by the present invention using a photographic camera, or video camera, which comprises a lens equipped with an S-type lens mount system (or S- mount) and at least one lens mounted on said lens mount system.
Thanks to the use of standard S-mount type systems, the variability of the configurations (working distance, enlargement) is concentrated in a single point that can easily be interchanged and managed at the production process level, which is thus optimised.
These and further objects of the present invention will be made clearer by the reading of the following detailed description of some preferred embodiments of the present invention, to be understood as a non-limiting example of the more general concepts claimed.
