Mydriasis effect on-site inspection system

Abstract

The invention relates to a mydriasis effect on-site inspection system, which comprises: a pupil acquisition mechanism used for acquiring each reliable pixel in a signal sharpening picture and combining each reliable pixel to obtain a corresponding pupil acquisition area; a parameter capturing mechanism which is used for acquiring each depth-of-field value of each reliable pixel in the signal sharpening picture, and outputting the depth-of-field value with the most occurrence frequency in the depth-of-field values as a representative depth-of-field value; a volume identification mechanism which is used for estimating the pupil dispersion area based on the area percentage of the pupil acquisition area occupying the signal sharpening picture and the representative depth-of-field value; and effectiveness detection equipment which is used for sending a mydriasis effective signal when the received pupil dispersion area exceeds the limit. According to the invention, an intelligent recognition mechanism can be adopted to carry out electronic judgment on the dispersion degree of the pupils of the patient suffering from eye diseases, so that errors and low efficiency of manual judgment are overcome, and the situation that subsequent eye detection operation is free of work is avoided.

Description

technical field [0001] The invention relates to the field of interpupillary distance measurement, in particular to an on-site inspection system for mydriasis effect. Background technique [0002] The pupil is the small round hole in the center of the iris in the animal or human eye, which is the channel for light to enter the eye. Contraction of the pupillary sphincter muscle on the iris causes the pupil to narrow, contraction of the pupillary dilator muscle causes the pupil to dilate, and the dilation and constriction of the pupil control the amount of light entering the pupil. [0003] The pupil is located in the front of the vascular membrane of the eyeball, that is, the center of the sclera and the round foramen. The smooth muscle lining the pupil is called the pupillary sphincter. The pupil narrows when the sphincter contracts. The smooth muscle that runs radially along the pupil is called the pupillary dilator. When the dilated muscle contracts, the pupil dilates. ...

Problems solved by technology

[0004] In the prior art, many tests on patients with eye diseases require the dilation of the pupils to clearly identify various parts of the patient's eyes and determine the pathology through the pupils. It can be seen that whether the pupil dilation is effective or not depends on whether the pupils are dilated. It can play a key element in various subsequent detections. However, in the prior art, the effectiveness of mydriasis is judged manually. The accuracy and efficiency of this judgment mechanism cannot meet the current needs.
