Abstract
The invention relates to a corneal topography instrument which comprises a real-time image monitoring system, a computer image processing system and a projection system; a light source in the projection system adopts a color projector, and projecting apertures have at least two colors; and the projecting apertures are red, green and blue. After the structure is adopted, a corneal topography can be more accurate through the apertures with different colors, because the apertures of three primary colors do not interfere with one another; and even the apertures are superposed, the distance between two apertures is smaller than that between apertures of the same color, so that the accuracy of the corneal topography can be improved.
Description
Technical field
The present invention relates to the armarium industry, especially relate to a kind of corneal topographers of measuring corneal topography.
Background technology
At present, existing corneal topographers mainly comprises three part: PlacidoShi dishes projection system, real time imaging monitoring system and Computerized image processing systems, this computer assisted corneal topography can accurately be analyzed the form of whole anterior corneal surface and the characteristics that are changed to of curvature with it, makes systematically, objectively, accurately analyzes the cornea character and become possibility.But, what this employing PlacidoShi dish projection system adopted is the light (mostly being white light) of same color, certain distance is arranged between aperture and aperture, aperture is closeer, measure dot number is more, and precision is higher, yet the distance between two apertures has diminished, the light of two apertures can disturb, and so just can not obtain clearly corneal topography; To work as when also needing more accurate corneal topography, this instrument has not just reached required effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of corneal topographers that can access more accurate corneal topography.
The technical solution adopted for the present invention to solve the technical problems is: a kind of corneal topographers, comprise real time imaging monitoring system, Computerized image processing system and optical projection system, what the light source in the described optical projection system adopted is color projecting apparatus, and the aperture of projection is red green blue tricolor.
Further concrete in order to reach more accurate effect, described aperture is three kinds of primary colors of red, green and blue.
The invention has the beneficial effects as follows: adopted after the said structure, can be by trichroism aperture so that corneal topography be more accurate, because three primary colors can be distinguished fully, so that the density ratio of two apertures wants Senior Three doubly with the distance between the color aperture, three times of the precision of raising corneal topography.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, Computerized image processing system; 2, real time imaging monitoring system; 3, optical projection system.
The specific embodiment
A kind of corneal topographers comprises real time imaging monitoring system 2, Computerized image processing system 1 and optical projection system 3 as shown in Figure 1, and what the light source in the described optical projection system 3 adopted is color projecting apparatus; Described aperture is three kinds of colors of red, green and blue.
At first trichroism aperture is projected on patient's the cornea by color projecting apparatus, carry out the image processing by real time imaging monitoring system 2 with being transferred to Computerized image processing system 1 after the image acquisition afterwards, form afterwards corneal topography; Because can the handling the whole district by image RGB and divide of three primary colors light, the distance between the aperture is more homochromy, and aperture increases by 3 times, when computer is processed, can obtain more process points, so that the corneal topography of formation is more accurate, and assisted diagnosis.
It is emphasized that above is better implementation column of the present invention, and every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
Claims (2)
1. corneal topographers, comprise real time imaging monitoring system (2), Computerized image processing system (1) and optical projection system (3), it is characterized in that: what the light source in the described optical projection system (3) adopted is color projecting apparatus, and the aperture of projection has two kinds of colors at least.
2. corneal topographers according to claim 1, it is characterized in that: described aperture is three kinds of colors of red, green and blue.
