Real-time tear film rupture detection method, computer readable storage medium and device

The invention discloses a real-time tear film rupture detection method, a computer readable storage medium and a device, and the method comprises the steps: S1, collecting a human eye image with a placido grid, and obtaining a plurality of frames of human eye images from the time when the eyes are opened to the maximum after the current blinking to the time before the next blinking; the placido grid comprises a plurality of concentric circles and a plurality of segmentation lines radially extending from the center of the placido grid; s2, identifying a pupil center of the human eye image, extracting a grid line graph, obtaining a central connected domain and an accurate center of the grid line graph, translating the grid line graph to enable the accurate center of the grid line graph to coincide with a preset center, judging whether the pupil center of the human eye image is in the central connected domain or not, and if yes, performing a step S3; s3, recognizing an eyelash shielding area according to the cha
