Self-service infrared eccentric photography optometry instrument and self-service optometry method

Abstract

The invention discloses a self-service infrared eccentric photography optometry instrument and a self-service optometry method. The optometry instrument includes: an illumination light source, an aperture, a filter, an imaging element, a dichroic mirror, an integrated controller, and a camera that can move along the optical axis. Imaging lens; the integrated controller is connected with an external central processing device; when the refractometer is in the preview state, the integrated controller controls the imaging lens to move along the optical axis, and receives the position feedback signal of the imaging lens until the human eye is in the working position; Then, the integrated controller controls the lighting source and the imaging element to flash and take pictures synchronously, completes the image collection of human eyes, and finally completes the self-service optometry; in the whole process, the central processing device realizes the entire process of self-service optometry by controlling the integrated controller; The whole process does not require the cooperation of others, and the tester can achieve the purpose of self-refraction by using the infrared eccentric camera. Therefore, the refractometer and the method save manpower and material costs.

Description

technical field [0001] The invention belongs to the field of refraction detection equipment, and in particular relates to a self-service infrared eccentric photography optometry instrument and a method for realizing self-service optometry by using the optometry instrument. Background technique [0002] At present, the automatic inspection equipment of human eye refraction is mainly desktop computer refractometer. This kind of equipment requires the operator to perform actions such as aligning the pupils and adjusting the working distance for the testee. The testee actively looks at the image in the instrument to measure the refraction of the testee, so the testee cannot do it by himself examine. That is to say, the device requires at least one person to operate the equipment, and another person cooperates with the inspection to complete the detection of the refraction of the subject. Therefore, operating the device to detect the refraction of the human eye wastes manpower, ...
