在本文中,我們提出了一種新穎而強大的基於視覺及系統單晶片(SoC)的系統作為感測器,有效地偵測年長者跌倒。我們所提出的方法包含五個步驟:初始光源穩定性確認,基於梯度差的前景偵測,基於型態學膨脹和多影格的前景建構,解決錯誤跌倒偵測問題,以及使用基於通用輸入/輸出的跌倒警告傳輸之跌倒偵測確認。實驗使用影片實測,證明與相關方法相比,我們所提出的方法擁有低功耗,低成本和高精度的優點。
In this paper, we propose a novel and robust vision- and system on chip (SoC)-based system as a sensor to effectively detect falls for the elderly. The proposed method consists of five steps: the initial light stability confirmation, gradient difference-based foreground detection, dilation- and multi-frame-based foreground construction, solving the false fall detection problem, and fall detection determination with a general-purpose input/output based fall warning transmission. Based on the real test videos, the comprehensive experiments have justified the low-powered, low cost, and high accuracy merits of the proposed method when compared with the related methods.
