Eyeball tremor auxiliary instrument based on eyeball tracking

Номер: CN116211239A
Автор: CHENG LIANG, ZHANG YONGQIANG
Принадлежит:

An eyeball tremor auxiliary instrument based on eyeball tracking is characterized in that a connecting rod at the front end of a head fixing frame fixes a camera structure through bolts, and the lower end of the connecting rod is connected with a display screen. When eyeballs rotate unautonomously, eyeball coordinates are fed back to the processor in real time through the eyeball tracking camera, the processor changes the image display position of a middle image shot by the outdoor scene camera along with the eyeball coordinates shot by the eyeball tracking camera at any time according to the coordinates changing at any time, and the image display position is displayed on the displayer in real time. The patient can observe conveniently.
