Abstract

Non-invasive measurement of human body composition by Near-Infrared(NIR) spectroscopy is one of hot research topics in Biomedical Photonics field. However, the practical application of this technique is not available, yet because of the uncertainty of measurement conditions during in vivo measurement. The uncertainty would greatly influence the acquisition of spectral signal which reflects different concentrations of the constituent of human body. The location of optical sensor has been proved to be associated with the diffused reflection light. In this talk, a computer vision localization method was proposed, which is based on image matching to localize optical sensor and further the impact of optical sensor position and orientation variance can be decreased. Experiment results showed that the uncertainty of measurement could be reduced significantly.
