Acquisition kit
An acquisition kit including: a mobile telephone; a mobile telephone holder including: —a spacer opening via an oral aperture, intended to be inserted into the user's mouth, and via an acquisition aperture, and —an adapter fastened to the spacer and defining, with the spacer, a chamber opening via the oral aperture and via an adapter aperture, the adapter including a base to which the mobile telephone is rigidly but removably attached in an acquisition position in which the objective lens of the mobile telephone has an at least partial view of the oral aperture, through the adapter aperture and the acquisition aperture, the oral aperture having a curvature about a vertical axis in the service position, the radius of the curvature being greater than 20 mm and less than 80 mm.
1 . An acquisition kit comprising:
a cell phone having
a front face,
a rear face with a screen, and
a side edge, defining the thickness of the cell phone and connecting the front and rear faces;
the cell phone being provided with a 2D and/or 3D data acquisition lens;
a cell phone holder comprising
a spacer, opening out through an oral opening intended to be inserted in the mouth of the user and through an acquisition opening, and
an adapter attached to the spacer and defining with the spacer a chamber opening out through the oral opening and through an adapter opening, the adapter comprising a base to which the cell phone is rigidly attached, preferably removably, in an acquisition position in which the lens has an at least partial view of the oral opening, through the adapter opening and the acquisition opening, the spacer having
a body of generally tubular shape, defining the oral opening and
a distal flange extending outward from the body and shaped so as to be inserted between the user's lips and teeth,
the oral opening extending partially outside the plane passing through its center and perpendicular to the axis connecting the center of the oral opening and the center of the acquisition opening,
the oral opening having a curvature about a vertical axis in the service position, the radius of said curvature being greater than 20 mm and less than 80 mm.
2 . The acquisition kit as claimed in claim 1 , wherein the distal flange has a lateral end separated from said plane by a distance of greater than 5 mm and less than 12 mm.
3 . The acquisition kit as claimed in claim 1 , wherein said radius of said curvature of the oral opening is greater than 40 mm and less than 60 mm.
4 . The acquisition kit as claimed in claim 1 , wherein the oral opening has a curvature exclusively about said vertical axis.
5 . The acquisition kit as claimed in claim 1 , wherein the ratio between the distance between the lateral ends of the distal flange and said distance between said lateral ends and said plane is between 5 and 8.
6 . The acquisition kit as claimed in claim 1 , wherein the distal flange lies in the extension of the oral opening.
7 . The acquisition kit as claimed in claim 1 , wherein the outer surface of the spacer has, at any point in the transition zone between the distal flange and the body, a radius of curvature at said point of greater than 1 mm.
8 . The acquisition kit as claimed in claim 7 , wherein the radius of curvature at said point is greater than 1.5 mm.
9 . The acquisition kit as claimed in claim 8 , wherein the radius of curvature at said point is greater than 3 mm.
10 . The acquisition kit as claimed in claim 1 , wherein the distal flange has, continuously and over a length of greater than 10 mm, a height of less than 3 mm.
11 . The acquisition kit as claimed in claim 10 , wherein the region in which the distal flange has, continuously and over a length of greater than 10 mm, a height of less than 3 mm is centered on a labial frenulum in the service position, when the user is holding the acquisition kit in front of them.
12 . The acquisition kit as claimed in claim 1 , wherein the distal flange has a maximum height of greater than 3 mm and less than 8 mm.
13 . The acquisition kit as claimed in claim 1 , wherein the chamber comprises a divergent segment ending at the oral opening, said divergent segment being defined by a wall having a constant thickness.
14 . The acquisition kit as claimed in claim 1 , wherein the adapter is removably attached to the spacer.
15 . A method for acquiring 2D or 3D data by means of an acquisition kit according to claim 1 , said method comprising the following steps:
b) assembly of the acquisition kit, in particular by attaching the cell phone to the adapter, and optionally the spacer to the adapter;
c) insertion, by the user, of the end of the spacer defining the oral opening into the mouth of the user;
d) positioning, by the user, of the oral opening opposite teeth for which said data are to be acquired;
e) activation of the cell phone in such a way as to acquire said 2D or 3D data;
f) modification of the position of the oral opening, then return to step e).
16 . The method as claimed in claim 15 , comprising before the step b), the following step a): selection, by the user, of a spacer from a set of available spacers.
17 . The method as claimed in claim 16 , wherein at step a) the selection is made on the basis of personalization marks borne by said available spacers and/or the morphology of the user.
18 . The method as claimed in claim 15 , wherein at step c), the insertion is made by inserting the flange of the spacer between their lips and their teeth.
19 . The method as claimed in claim 15 , wherein at step f) the modification is made by rotation about the user.
