Embodiment Construction

[0011] First of all, it should be noted that the present invention can be widely applied to different types of physiological detection or monitoring devices. Those skilled in the art can understand that the explanatory terms in this embodiment are general descriptions that do not limit the application, such as procedures, processes or signals. Processing terms include but are not limited to descriptions, objects to be detected, and physiological characteristics that can be detected.

[0012] The method for identifying and judging physiological characteristics using invisible light provided by the present invention mainly includes at least a plurality of light emitting units capable of projecting invisible light, a signal processing unit, and a digital image sensing unit. The invisible light projected by the light-emitting unit has different wavelengths respectively. The light-emitting unit of this preferred embodiment takes a near-infrared LED (Near-Infrared LED, NIR LED) as an...

Abstract

A method for identifying and determining a physiological characteristic using invisible light includes the steps of: respectively activating at least two light-emitting units to emit an invisible light onto a human body to be detected in such a manner that only one light-emitting unit is activated at a time wherein each of the at least two light-emitting units is configured to emit a different wavelength of invisible light, then capturing a real-time image signal from the human body corresponding to the invisible light emitted by each light-emitting unit and reflected by the human body, and then analyzing each real-time signal and defining a skin area according to the analysis result, and finally calculating the change of reflected light intensity of the skin area to obtain a measured value corresponding to the physiological characteristic of the human body.

Description

technical field [0001] The present invention relates to a detection device, in particular to a method for identifying and determining physiological characteristics by using invisible light. Background technique [0002] In order to take care of infants, young children, patients with disabilities, and the elderly more comprehensively and efficiently, in addition to the personal contact of parents or nursing staff with those who need care, there are currently many auxiliary detection tools or devices to assist in confirming care. the physiological state of the patient. [0003] The simple detection device is to use a digital camera to record images of the person being cared for for a long time, and then transmit the obtained digital image to a cloud server, computer, or mobile phone through the Internet, so that the caregiver can observe whether the person being cared for is abnormal. In addition, there is also a monitoring method that directly pastes electrode sheets on the ...
