Automatic human eye tracking system and method for computer optometry instrument

Abstract

The invention relates to an automatic human eye tracking system for a computer optometry instrument, which is characterized by comprising a key module, a signal acquisition module, an image processingunit, an ARM microcontroller, a three-dimensional moving module and an SD card module, wherein the image processing unit comprises a scanning module, an identification module, a tracking module and afocusing module. The invention also relates to an automatic human eye tracking method for a computer optometry, which is characterized in that the tracking method comprises the following steps of: 1)mode selection; 2) signal acquisition; 3) signal processing; 4) three-dimensional tracking adjustment; 5) data storage. The system is scientific and reasonable in design, accurate in positioning andfocusing and capable of realizing automatic and intelligent tracking and positioning of human eyes, improving vision testing precision and testing speed, and improving working efficiency.

Description

technical field [0001] The invention belongs to the field of medical devices, relates to a computerized optometry instrument, in particular to a computerized optometry instrument human eye automatic tracking system and method. Background technique [0002] With the advent of the information and paperless era, the use of electronic products has gradually become popular in our lives. However, while the electronic age brings convenience to us, it also brings vision problems to users' eyes. Faced with computers or mobile phones for a long time, people's eyes will be tired and tired, resulting in vision loss. Therefore, there are more and more glasses wearers now. [0003] In order to better protect eyesight and protect glasses, the selection requirements for glasses must be improved. When purchasing glasses, the detection of vision must be accurate and precise. At present, the visual acuity test mainly uses the computer optometry instrument. The existing computer optometry in...

Problems solved by technology

At present, the visual acuity test mainly uses the computer optometry instrument. The existing computer optometry instrument needs the optometrist to manually adjust the joystick of the optometrist multiple times to realize the search and positioning of the human eye. The adjustment speed is affected by the experience of the optometrist. Therefore, for The test accuracy of vision is low, the positioning accuracy is poor and the test speed is slow, which affects the accurate test of human vision and is not good for vision protection
