Video acquisition and analysis system and method for realizing cognitive dysfunction screening function by simulating facial expressions through videos

Abstract

The invention relates to a video acquisition and analysis system for realizing a cognitive dysfunction screening function by simulating facial expressions through videos. The system includes a self-evaluation screening module for setting a stimulus source for testing through images or videos, and encrypting and transmitting data; and a cloud analysis and evaluation module for transmitting the acquired image data to a trained deep learning model for analysis and diagnosis, and feeding back a diagnosis result in real time. The invention also relates to a video acquisition and analysis method forrealizing a cognitive dysfunction screening function by simulating facial expressions through videos. The video acquisition and analysis system and method for realizing the cognitive dysfunction screening function by simulating facial expressions through video scan perform objective assessment before professional diagnosis and treatment, are intelligent and efficient, save the medical treatment time of a patient, provide convenience for those who cannot go to a medical organization for various reasons, reduce the burden of medical care, the burden of caregivers and socioeconomic costs, overcome the limitations of illiteracy and low education levels, and can more accurately screen the cognitive dysfunction in the future.

Description

technical field [0001] The present invention relates to the field of disease prevention, in particular to the field of self-identification and management of brain health, and specifically refers to a video acquisition and analysis system and method thereof that realize the cognitive impairment screening function by stimulating facial expressions through video. Background technique [0002] Neurocognitive impairment includes mild cognitive impairment (Mild Cognitive Impairment, MCI) and severe neurocognitive impairment (dementia). The diagnosis rate of the disease is only 20%-50% in developed countries, lower in low-income and developing countries, and 90% of patients in India are undiagnosed. China is one of the countries with the largest number of dementia and the fastest growing population, but the early diagnosis rate is as low as 5%-30%. [0003] In the past 10 years, my country has increased the community prevention and intervention of dementia. Early identification o...
