Abstract: The present disclosure relates to a method and a system for standardizing a hemodynamics measurement result and a non-transitory computer-readable recording medium. According to one aspect of the present disclosure, provided is a method for standardizing a measurement result obtained from a device for monitoring hemodynamics, the method comprising the steps of: capturing an image of a subject wearing a monitoring device; defining a photogrammetric coordinate system on the captured image, and converting a preset local coordinate system on the monitoring device into the photogrammetric coordinate system; and converting the photogrammetric coordinate system into a standard coordinate system which is based on a standard space.

Abstract: According to one aspect of the invention, there is provided a method for monitoring hemodynamics, comprising the steps of: acquiring information on a posture of a first subject wearing a monitoring device; estimating a motion artifact predicted to be included in a spectroscopic measurement signal from the first subject which is measured by the monitoring device, with reference to the acquired information on the posture of the first subject, and a motion artifact estimation model for defining a correlation between a posture of at least one subject and a motion artifact occurring in a signal measured from the at least one subject; and removing the estimated motion artifact from the measurement signal from the first subject.

Abstract: According to one aspect of the present disclosure, there is provided a method of estimating biometric information about a head using a machine learning, the method including: acquiring an analysis target optical signal detected from a head portion of a person to be measured by at least one optical sensor disposed on the head portion of the person to be measured; and estimating the biometric information about the head of the person to be measured by analyzing the acquired analysis target optical signal using an estimation model learned based on data about an anatomical structure of at least one head portion, data about a biometrical state of the at least one head portion, and data about an optical signal associated with the data about the anatomical structure of at least one head portion and the data about the biometrical state of the at least one head portion.
