影像式心率活动侦测装置及其方法;APPARATUS BASED ON IMAGE FOR DETECTING HEART RATE ACTIVITY AND METHOD THEREOF

摘要

本揭露是关于一种影像式心率活动侦测装置与方法，该方法包含以下步骤：针对一监测对象取得复数彩色影像；根据一预设之肤色目标条件，界定彩色影像中之一目标区域；针对目标区域执行一彩色影像组成分析，以取得一红色频道讯号、一绿色频道讯号以及一蓝色频道讯号；依据一独立成分分析法针对红色、绿色以及蓝色频道讯号进行运算，以分别取得第一、第二以及第三独立成分讯号；针对第一、第二以及第三独立成分讯号分别执行一频域转换程序、一讯号能量运算程序与一讯号适化程序，以取得一滤波讯号；并根据一预设条件针对滤波讯号执行比对，以确认监测对象是否为真人，并据之作出一分析指示；以及根据该分析指示执行一生理资讯分析程序。; based on a complexion target condition, defining a target region; performing color composition analysis on the target region to obtain red channel signal, green channel signal and blue channel signal, respectively; performing independent component analysis on separate red, green and blue channel signals to obtain separate first independent component signal, second independent component signal and third independent component signal; performing frequency domain transform, signal energy computation and signal optimization processes on separate first, second and third independent composition signals to obtain a filter signal, comparing filter signal based on a pre-set condition to determine if target region belonging to a human; and performing a bio-physiological information analysis.
