Automatic stereoscopic vision and colour vision examination instrument

Abstract

The invention discloses an automatic stereoscopic vision and colour vision examination instrument, which belongs to the technical field of medical instruments and relates to an examination instrument. The technical problem to be solved is an automatic electronic stereoscopic vision and colour vision examination instrument. The technical scheme comprises an imaging system, an imaging system support, a data processing system, a bottom plate, a case, a power switch and other parts. The imaging system support is mounted on the right part of the bottom plate; the imaging system is mounted on the imaging system support; a computer in the data processing system is mounted on the bottom plate; a display screen is fixed on the case; a printer is mounted under the display screen; the power switch is inlaid on the right sidewall of the case; and the display screen, the printer and the power switch are respectively connected with the computer through wires. The examination instrument has the advantages that the automatization of examination can be realized, the precision is high, and the functions of displaying, storage and printing a result in real time can be realized.

Description

technical field [0001] The invention belongs to a stereo vision and color vision tester related to the technical field of medical instruments. Background technique [0002] Pilots, various types of drivers, high-altitude operators and other industries have strict requirements on vision, especially for pilots. The pilot's vision indicators should be checked regularly to determine whether the pilot's vision meets the flight conditions. Stereoscopic vision and color vision detection are two essential and important indicators in visual inspection. At present, the methods and instruments used to detect stereo vision and color vision include: Stereo vision inspection: Insert two standard pictures with different parallax angles into a stereo mirror for observation to determine the minimum stereo vision index. Color vision inspection: Using the prepared color vision pictures, the human eye can directly recognize the pictures. The above-mentioned detection methods or equipment are ...

AI Technical Summary

Problems solved by technology

The above-mentioned detection methods or equipment are primitive and outdated, and are greatly affected by external factors. The inspection results are not accurate enough, and the replacement of pictures requires manual operations. It is time-consuming and labor-intensive to conduct a large-scale medical examination for recruiting pilots, and the objective requirements for inspection venues, light, etc. are relatively strict.
