Method of measuring palpebral fissure height, and a device and a storage medium for the same

Abstract

The application relates to a method, device and storage medium for measuring palpebral fissure height. The method comprises capturing the first eye position image of the user looking straight ahead in a near-infrared light field of 700-1200 nm at the position in front of the eye; and segmenting the background, the iris, the sclera and the pupil from the first eye position image by the training method of a neural network. The pupil center was extracted from the segmented pupil, and the vertical pupil center line was obtained. The distance between the junction point of the sclera, the iris or the pupil on the center line of the pupil and the background is obtained, and the palpebral fissure height is calculated using the distance.
