The eye key points with obvious semantic features are labelled, and the marking efficiency is improved.

The invention discloses an eyelid positioning method based on strong direction weighted edge detection and RNL goodness of fit. An existing straight line fitting positioning method is high in positioning speed but low in positioning precision. The parabola fitting positioning method is high in fitting positioning precision, but low in positioning speed. The method comprises the following steps: segmenting upper and lower eyelids according to an iris circle center position, and determining upper and lower eyelid areas; secondly, preprocessing an image before eyelid detection by using a strong direction weighted edge-preserving denoising smoothing filtering operator; secondly, suppressing eyelash interference by using a strong direction weighted edge detection operator, and dynamically selecting edge detection operator parameters according to gray scale contrast values of regions above and below the eyelid edge in the iris image to obtain candidate eyelid edges to be fitted; and finally,fitting eyelid edges by adopting a least square method parabola, and screening eyelid edge selection points by taking RNL goodness of fit as an index to finish eyelid positioning. The method has goodrobustness, and an ideal positioning result can be obtained even for an upper eyelid which is shielded by eyelashes.

Disclosed herein is a contact lens comprising a lenticular in a superior portion of the contact lens wherein the contact lens attaches to an upper eyelid of a wearer by the lenticular interacting withan upper tarsal plate of the upper eyelid of a wearer, said interaction allows the contact lens to translate upwards in downgaze and maintain rotational stability. In one aspect, the lenticular has atop surface, said top surface having a shape selected from the group consisting of flat, flat with rounded corners, concave, convex or tapered having a thicker portion closer to an edge of the contact lens, or combinations thereof. In another aspect, the lenticular is comprised of a plurality of lenticular sections. In yet another aspect, the lenticular is anatomically-shaped.

The invention discloses a blinking data statistical method and device, a computer readable storage medium and electronic equipment. The method comprises the steps: obtaining video data containing eye movement in a preset time period, recognizing each frame of image of the video data, obtaining a target region between an upper eyelid and a lower eyelid, calculating the palpebral fissure height corresponding to the target region, and according to the palpebral fissure height, determining the opening and closing state of the target region; finally, according to the opening and closing state of the target region of all frame of images in the video data, performing statistics to obtain blinking data in a preset time period; and namely, obtaining the target region by automatically obtaining the video data within the time period and identifying each frame of image in the video data, and determining the opening and closing state according to the palpebral fissure height, so that the blinking data is counted, the difficulty of data statistics is reduced, the palpebral fissure height is calculated by automatically identifying the target region, the blinking data can be accurately obtained, and an accurate data basis is provided for subsequent pre-judgment.

Controllers for dry eye treatment apparatus and methods are described herein which generally comprise a patch or strip affixed to the skin of the upper and/or lower eyelids to deliver heat to the one or more meibomian glands contained within the underlying skin. The treatment strip or strips include one or more strips configured to adhere to an underlying region of skin in proximity to one or both eyes of a subject such that the one or more strips allow for the subject to blink naturally without restriction from the one or more patches. A controller is in communication with the one or more strips and is programmable to monitor a temperature of the one or more strips to provide a treatment therapy above a threshold temperature of, e.g., 39° C., and below a maximum temperature of, e.g., 48° C., over a treatment period of 12 minutes.

The invention discloses a wireless-transmission-based detection system and method for a fatigue state of a learner. A wireless optical mouse device is manufacturing into a spectacle additional device and then the device is installed at a spectacle frame to obtain a relative moving direction, a moving distance, and a moving speed value of a palpebra superior, and then the infroamtion is transmitted to an external terminal device having a wireless communication function by a wireless communication module; the external terminal device processes a movement track to obtain eyelid blink data, and then the external terminal device transmits the eyelid blink data to a remote monitoring server by network transmission; and the remote monitoring server processes and analyzes the eyelid blink data to determine a learning state of a learner. According to the invention, real-time collection, transmission, and processing of eyelid blink information of a learner are carried out and thus whether the learner is in a fatigue learning state is determined, so that corresponding measures are taken.

The invention discloses an eye drive control method and device, a storage medium and electronic equipment. The method comprises the steps that a target picture configured for an anchor object in advance is displayed in a current live broadcast picture, wherein the face of a virtual animal object is displayed in the target picture; on the basis of the collected face image of the anchor object, the monocular closing feature of the anchor object is recognized, the monocular closing feature is obtained through calculation based on the position offset of a plurality of closing point sets collected on the single eye of the anchor object, and the single closing point set comprises an upper eyelid point and a lower eyelid point which intersect with the same straight line; and the eyes of the virtual animal object in the target picture are driven and controlled to perform synchronous closing adjustment according to the eye closing degree indicated by the single-eye closing feature. The technical problem that the accuracy of eye drive control cannot be guaranteed in the prior art is solved.

A method of making a face mask for a face of a human user can include determining a lower eye region bound and determining an upper eye region bound by locating an upper bound of the eyeball as determined by a peak point of an arc of concavity in an upper eyelid of the at least one eye when the eye is closed. The method can also include setting a first anchor point about 0 mm to about 10 mm below the lower eye region bound, and setting a second anchor point about 0 mm to about 10 mm above the upper eye region bound; and defining at least one eye opening for a face mask having first edge that intersects the first anchor point and a second edge that intersects the second anchor point.
