| titleOfInvention | Color-coded topograph and procedure for determining a mathematical model of a corneal surface |
| abstract | A corneal surveyor comprising: a multicolored stimulator (100) comprising a plurality of light sources (130) arranged to form a multicolored pattern of points of origin (130) to project a plurality of light rays on a surface of an object of interest , such as a cornea (110); a lens-camera system (170) arranged to receive a respective plurality of light rays reflected on the surface of the object of interest, thus forming a pattern of image points; a unit of calculation (180) to determine a mathematical model of the surface; wherein the calculation unit comprising a memory unit provided with color pattern information based on the multicolored pattern of the origin points (130) of the stimulator; The information of the color pattern comprises a unique identifier for each of the origin points, the calculation unit (180) is arranged to establish, for each of the plurality of reflected light rays, a one-to-one correspondence between a point of origin and an image point based on the information of the color pattern; The calculation unit (180) is also arranged to build, based on the positions of the points of the image and the positions of the corresponding origin points, the mathematical model of the surface, characterized in that the unique identifier is a unique identifier based in at least one color of neighboring points of origin of the point of origin. |
