Problems solved by technology

[0004] However, the above implementation requires the use of a wearable device to achieve blink detection, and for users using terminal devices (such as mobile terminals, PCs, etc.), when the user is not using the wearable device, it is impossible to detect whether the user is blinking or not. Generate eye blinking, that is, the application scenarios of the above-mentioned wearable devices are limited
For example, when a user plays a game through a mobile terminal, the user cannot control the game operation by blinking.

Abstract

The invention provides a method and apparatus for blink detection. The method includes acquiring a plurality of frame detection images; acquiring an eye feature vector of the detection image; formingan eye feature vector of the multi-frame detection image into a first feature vector set; determining an eye blinking state corresponding to the first feature vector set by querying a mapping relationship of the first feature vector set, wherein the mapping relationship is a mapping relationship between a second set of eigenvectors and a blinking state. According to the technical proposal of the present application, the operation of an application program can be controlled based on the blinking action for an application scenario in which a user does not use a wearable device, and the blinkingaction detection has high accuracy, high reliability, low computational overhead, and low resource occupancy of the terminal device.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a blink detection method and device. Background technique [0002] Since eye movements contain a wealth of emotional and physiological information, the traditional button operation can be replaced by blinking to directly interact with the program, which can significantly improve the user experience. [0003] At present, sensors can be implanted in wearable devices (such as smart glasses, etc.), so that the wearable device can detect the electro-oculogram waveform signal, and judge whether the current The blinking action is generated, the detection result is accurate, and the detection efficiency is high. [0004] However, the above implementation requires the use of a wearable device to achieve blink detection, and for users using terminal devices (such as mobile terminals, PCs, etc.), when the user is not using the wearable device, it is impossible to detect ...
