Abstract
The invention relates to a portable eyeball static rotation measuring instrument. The measuring instrument comprises a high-definition infrared camera, an image processing module, an image acquisitionbutton, an infrared light source, a visible light source, a test window and a wearable helmet. The high-definition infrared camera, the image processing module, the image acquisition button, the infrared light source, the visible light source and the test window are all arranged on the wearable helmet, and the wearable helmet is arranged in a longitudinal direction and can be movably and detachably arranged in front of the eyes of a user. The two high-definition infrared cameras are symmetrically arranged in a horizontal direction and are arranged inside the wearable helmet, and the high-definition infrared cameras can simultaneously capture iris images of both eyes; and the infrared light source and the visible light source are arranged between the two high-definition infrared cameras. The measuring instrument is portable, rapid in measurement and low in requirement for the measurement environment, a doctor can understand the static rotation angle of a patient only through simple operation, the problems in the prior art are solved, and the measuring instrument serves as a reference for operation mode recommendation.
