Adaptive psychological adjustment device, real-time eye movement delay calculation method and storage medium

Abstract

The invention discloses a portable self-adaptive psychological adjustment instrument, a real-time eye movement delay calculation method and a computer readable storage medium with computer program stored therein. The method comprises the following steps of: outputting a guide target, identifying eye feature points from a face image to obtain an eye image; performing a image enhancement and an adaptive threshold segmentation processing on the eye image to obtain an iris image of the eye; positioning the pupil center position by adopting a projection integral method and a template matching method to the iris image, and when the relevant value of the eye-opening template matching is larger than a set threshold value, positioning the pupil center position and recording the pupil center position corresponding to the frame, performing the smoothing filtering and the differential filtering on the obtained moving data of the central position of the pupil of the human eye of the obtained frame,taking the eye movement time as the state quantity to guide the moving data of the target and the position data of the pupil center of the eye frame as the observation data, and establishing a Kalmanfiltering equation, and calculating the time delay between the eye movement position data and the guide target motion data.

Description

technical field [0001] The invention belongs to portable medical equipment, and in particular relates to a portable self-adaptive psychological regulator, a method for obtaining real-time eye movement delay and a storage medium. Background technique [0002] The function of the eyes is to process external information or activities, and then transmit them to the human brain.
