Method and device for protecting privacy of ophthalmic patient and storage medium

Abstract

The invention discloses a method and device for protecting the privacy of an ophthalmic patient and a storage medium. The method comprises the steps: collecting an examination video of the ophthalmology patient; extracting image features of each frame of image in the examination video, performing region division on each frame of image according to organ position information in the image features, and obtaining a region to be subjected to precision reconstruction and a region to be subjected to weakening reconstruction according to a region division result; performing three-dimensional reconstruction on the to-be-precisely reconstructed region and the to-be-weakened reconstructed region to obtain three-dimensional reconstruction data corresponding to each frame of image; and rendering all the three-dimensional reconstruction data into a three-dimensional reconstruction video. According to the invention, each frame of image is divided into a plurality of image regions according to the position information, and the to-be-precisely reconstructed region and the to-be-weakened reconstructed region are obtained in the image regions and are subjected to three-dimensional reconstruction, so that most of case features of the ophthalmic patient can be reserved, and meanwhile, most of identity features of the ophthalmic patient can be covered; therefore, the privacy of the ophthalmic patient can be protected on the premise of not influencing diagnosis of the doctor.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method, device and storage medium for protecting the privacy of ophthalmology patients. Background technique [0002] With the prevalence of digitalization, digital medical care has gradually entered people's field of vision. Digital medicine refers to a new modern medical method that applies information technology to the entire medical process. However, in the process of implementing digital healthcare, there are also some risks and challenges. Among them, how to better protect patient privacy has become an urgent problem to be solved in digital medicine. Facial information digitally records disease signs and inevitably retains sensitive biometric information. How to accurately separate the two technically is a major technical difficulty in face privacy protection. [0003] The existing methods for protecting the privacy of ophthalmology patients mainly process im...

Problems solved by technology

[0004] The present invention provides a method, device and storage medium for protecting the privacy of ophthalmology patients, so as to solve the problem that the existing methods for protecting the privacy of ophthalmology patients cannot remove the identity information of the non-covered area, and the case characteristic information contained in the covered area is likely to be lost , leading to technical problems that make it difficult to protect the privacy of ophthalmic patients without affecting the doctor's diagnosis
