Abstract
The invention discloses a tilt-shift tomography eye scanning system and a method thereof, relates to the field of optical instruments for the ophthalmology, and aims at solving the problem of improvement of measurement accuracy. The scanning system comprises a light source (1), a fracture diaphragm (2), a projecting mirror group (3), a reflective device (4), eye forepart tissues (5), an eye (6), a focusing mirror group (7), a focusing camera (8), a plurality of tilt-shift imaging lenses (9) and a plurality of tilt-shift cameras (10). The plurality of tilt-shift cameras and the corresponding tilt-shift imaging lenses (9) can shoot and synthesize more accurate images for the same tangent plane of the eye forepart tissues (5), the shot images of each tangent plane are synthesized into accurate stereo images. The tilt-shift tomography eye scanning system and the method thereof are mainly used for examining eye forepart tissues.
Description
Technical field
The present invention relates to the opticianry instrument field, be specifically related to a kind of axle tomography eye scanning system and method thereof of moving.
Background technology
The following concrete defective of axle tomography eye scanning system ubiquity of moving at present both domestic and external:
Generally adopt single cover to move the axle scanning lens and move camera shaft, its image precision after computer is processed is still not high, can't be analyzed in same angle position, can only carry out the interpolation match by the picture of interval angle shot and form, so the accuracy of check measurement is relatively relatively poor.
Announced in 15th such as JIUYUE in 2010, publication number provides " a kind of tilt-shift fault scanning device " for the Chinese invention patent of CN 101828900 A, adopted and singly moved the axle camera technique, basically realized the rotation sweep function, but the defective of this patented technology on imaging precision still exists.In addition, in the characteristic of its claim 1 about the technical characterictic of " moving axle light path of photography equipment " only recorded and narrated " move axle light path of photography equipment ... be connected by wired mode between the external equipment ", other technical characterictics about " moving axle light path of photography equipment " have been documented in aforementioned part, and the documents " patent No. is the United States Patent (USP) of US6286958 " according to its description and accompanying drawing and this patent, all significantly show it is a cover " moving axle light path of photography equipment " and " video camera " of taking on the light path, so the defective of its poor accuracy certainly exists.
Do not see yet in the market and can overcome above defective, tilt-shift fault scanning system simple in structure, easy to assembly, that cost is lower, image quality is higher.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide never see on a kind of market can overcome this defective, practical function, well behaved axle tomography eye scanning system and the method thereof of moving.
The present invention adopts with following technical proposals:
System comprises light source 1, crack diaphragm 2, projectoscope group 3, reflective device 4, eyes leading portion tissue 5, eyes 6, focusing mirror group 7, focusing camera 8.
Also be provided with a plurality of imaging shaft camera lens 9, a plurality of camera shafts 10 that move of moving;
The described same tangent plane that moves 9 pairs of described eyes leading portion tissues 5 of imaging shaft camera lens that moves camera shaft 10 and correspondence thereof of every cover can photographic images.
Every cover is described move camera shaft 10 and the corresponding same tangent plane photographic images that moves 9 pairs of described eyes leading portion tissues 5 of imaging shaft camera lens thereof after, can the anglec of rotation to next tangent plane photographic images of described eyes leading portion tissue 5.
When the described same tangent plane that moves 9 pairs of described eyes leading portion tissues 5 of imaging shaft camera lens that moves camera shaft 10 and correspondence thereof of many covers is taken, adopt the mode photographic images of synchronization exposure.
When the described same tangent plane that moves 9 pairs of described eyes leading portion tissues 5 of imaging shaft camera lens that moves camera shaft (10) and correspondence thereof of many covers is taken, adopt the mode photographic images to the tow sides exposure of same tangent plane.
Preferably be provided with described camera shaft 10 and the corresponding described lens shaft 9 that moves thereof of moving of two covers.
Preferably, the described described lens shaft 9 that moves that moves camera shaft 10 and correspondence thereof of two covers organizes 5 formed primary optical axis to become axial symmetry to arrange along described reflective device 4 and described eyes leading portion.
The present invention compares with the contrast patent, and technical scheme is different, beneficial effect is different.The significant advantage of the present invention and beneficial effect are embodied in: overlap the described described lens shaft 9 that moves that moves camera shaft 10 and correspondence thereof more and take simultaneously, so that can photograph the picture of the positive and negative or more perspective of more or even same tangent plane in same angle, computer can carry out to each angle contrast compensation and the match computing of a plurality of pictures when processing these pictures, can calculate more the effective picture near described eyes 6 practical situations, thereby significantly improve the accuracy that detects.
