Nursing home-based personnel falling detection method and device, and medium

Abstract

The invention provides a person falling detection method based on a nursing home, and the method comprises the steps: obtaining a current image which is shot by an infrared thermal imager and contains a to-be-detected old person, and carrying out the calibration of the to-be-detected old person in the current image through a rectangular frame; comparing the diagonal coordinate of the rectangular frame at the current moment with the diagonal coordinate of the rectangular frame in the historical moment image to obtain the displacement of the diagonal coordinate at the current moment, and judging whether the displacement of the diagonal coordinate at the current moment is smaller than a preset diagonal coordinate displacement threshold; if yes, adding a numerical value obtained after a preset number to the response sensitivity value corresponding to the historical moment image serves as a current moment response sensitivity value, and judging whether the current moment response sensitivity value is larger than a preset response sensitivity threshold value or not. According to the people falling-down detection method based on the nursing home, the accuracy of people falling-down detection is improved, the efficiency of people falling-down detection is improved, and falling-down old people can be timely and effectively found.

Description

technical field [0001] The invention relates to the field of fall detection, in particular to a fall detection method, equipment and medium based on a nursing home. Background technique [0002] At present, with the rapid development of the economy, people's living standards are gradually improving, and the way of entering the nursing home for the elderly is gradually accepted by people. Nursing homes generally have escorts to take care of the daily life of the elderly. However, it is impossible for the escorts to accompany the elderly uninterruptedly, so the safety supervision of the elderly has become particularly important for nursing homes. Most of the safety supervision is to monitor whether the elderly fall to prevent the safety risks of the elderly. At present, most of the fall detection methods in nursing homes rely on the staff to observe the monitoring screen with the naked eye to judge whether the elderly have fallen. Just can't in time and effectively discover a...

Problems solved by technology

[0004] The second object of the present invention is to provide an electronic device, which can solve the problem that the current detection methods for people falling in nursing homes mostly use the staff to observe the monitoring screen with the naked eye to judge whether the elderly have fallen. The method relies entirely on manual experience, which cannot guarantee the accuracy of the test results, and cannot promptly and effectively detect the problem of falling elderly people.
