Definitions
- the invention relates to the general field of augmented reality, and more specifically to the application of textures in augmented reality.
- Augmented reality is a technology that may consist of superimposing real-time virtual images, or additional information, on images from the real world.
- augmented reality allows the display of virtual objects so that they appear to appear in the real world.
- a display module such as a screen where one can superimpose an image of a virtual object on a real world image (acquired for example by a camera).
- a display module such as augmented reality glasses such as "Microsoft Hololens" (trademark) glasses can be used to display a virtual object that the user will see as placed in the real world.
- An example of augmented reality application is the visualization of a virtual piece of furniture arranged to be seen by a user at a location in a room.
- the invention aims in particular to solve these disadvantages. Obiet and summary of the invention
- the present invention addresses this need by providing an augmented reality texture application method comprising:
- a display of at least the texture applied to the virtual three-dimensional object the display being made from a point of view in the virtual world corresponding to the position of the image acquisition module in the real world.
- the real world mentioned above targets the three-dimensional space of users.
- the virtual world aims for it a three-dimensional space that exists only numerically.
- This virtual space can be associated with a marker, for example orthonormal three-dimensional.
- the virtual space can be displayed on a display module (for example a screen or augmented reality glasses) from a chosen point of view using the conventional three-dimensional imaging techniques well known to humans. job.
- the visible marking portion makes it possible to implement this resetting step.
- the visible marking portion can make it possible to determine a marking orientation and also a dimension (for example a distance between two elements of the marking). 7
- the visible marking portion is associated with a real world landmark (for example an orthonormal landmark), and a virtual landmark will be developed based on the real world landmark.
- the virtual coordinate system thus developed will allow the display of a virtual object so that it appears in a desired location (for example when superimposed with an image of the real world.
- a point of the visible mark portion is chosen to form the origin of a real world mark
- a point of a virtual object to be placed at the origin of the virtual world mark will be displayed as if it were present at the origin of the real world landmark and thus on the marking.
- Texture mapping uses techniques generally designated by those skilled in the art by the Anglo-Saxon expression "texture mapping”.
- the displayed texture will be displayed as if it were applied to the actual object observed from the image acquisition module.
- the three-dimensional virtual object can be chosen taking into account the real object.
- This may in particular make it easier to preview a drawing corresponding to the texture to be made on the real object, and this may also facilitate a step of making a drawing corresponding to the texture on the real object.
- the method may comprise, after said display step, a step of making a drawing on the real object, this drawing being able to correspond to the texture.
- augmented reality is meant “so that a user sees a superposition of a virtual element (here at least the texture) on an image of the real world (for example, which is either seen directly by the 'user is displayed on a display module with texture)'.
- the method is a method of applying texture in augmented reality, it is implicit that by means of the display of the texture, an observer can observe the texture as superimposed on the real object.
- the display step is implemented by means of a screen, the acquired image can be displayed simultaneously with the texture.
- the method further comprises a display of said image of the real world, said texture applied to the virtual three-dimensional object being superimposed on said image of the real world displayed.
- This particular mode of implementation is particularly advantageous when the display step is implemented by means of a screen.
- the displayed texture will appear as if it is present on the real object, since the three-dimensional virtual object is chosen to correspond to the real object.
- the invention is nevertheless in no way limited to the display of the acquired image, and it is also possible to obtain a texture application in augmented reality without displaying the acquired image, for example by using a display such as glasses of augmented reality through which a user will see the texture and the real world directly.
- the three-dimensional virtual object is chosen from a three-dimensional virtual object library.
- a user can choose a virtual object that will have the form closest to that of the real object.
- the three-dimensional virtual objects of the three-dimensional virtual object library may be meshes well known to those skilled in the art, or else three-dimensional forms associated with parameters.
- a circular cylindrical three-dimensional shape may be associated with a diameter parameter and a height parameter.
- the method comprises a prior step of adjusting the virtual three-dimensional object.
- the prior adjustment step can be implemented after a prior implementation of some of the steps of the method so as to place a virtual object in the virtual world.
- the prior adjustment step may comprise the display of the virtual three-dimensional object, and preferably, if a screen is used for displaying, displaying an image of the real world acquired.
- the display of the three-dimensional virtual object can be implemented by displaying a partially opaque three-dimensional virtual object so that both the real object and the three-dimensional virtual object can be observed. If the three-dimensional virtual object is not perfectly superimposed on the real object, the user can easily observe the differences between the three-dimensional virtual object and the real object.
- This adjustment can comprise a displacement, in the virtual world, of the three-dimensional virtual object, or else a deformation of the virtual three-dimensional object in the virtual world.
- the adjustment step is implemented by means of a receipt of a command from a user.
- this step can be implemented by means of an interface for the user.
- the detection of said at least one portion of marking comprises the detection of a predefined number of particular points of the marking.
- the predefined number of particular points is 3, or between 3 and 20, or between 20 and 50, or even preferably between 50 and 100 or even greater than 50.
- a visual node is generally, for those skilled in the art, a break of a line or the end of a line.
- the marking is a non-repetitive pattern having a high contrast ratio or even black and white.
- the marking is in grayscale, and that the white color is associated with a black intensity of 0% and the black color with a black intensity of 100%, then we preferentially use a marking with elements having a difference in intensity of black of at least 70 points, which corresponds to a high contrast ratio (for example, a gray at 15% black and a gray at 85% black, or a gray white at 0% black and a gray at 70% black). It is also possible to use a colored pattern with colors associated with intensities of black separated by 70 points (for example a light yellow with 10% of black and a dark blue with 80% of black).
- the texture is applied to the virtual three-dimensional object in a zone distinct from that comprising the marking in the real world.
- This particular mode of implementation facilitates the implementation of a subsequent drawing step since the marking and its elements do not interfere with this step.
- the texture is applied to a predefined portion of the virtual three-dimensional object, for example at a location chosen by the user.
- At least a portion of an additional marking linked to the real object is visible on said real-world image, the method further comprising:
