A perfusion imaging-based non-contact autonomic nervous system response multi-dimensional bio-signal measurement system, comprising:
- a light source configured to emit in at least two different wavelengths, for measuring a multi-dimensional bio-signal in a non-contact manner;
- a multi-dimensional multi-spectral camera configured to photograph amplified reflected light reflected after emission from the light source, and generate an image sequence of the bio-signal;
- and
- a processor configured to receive the image sequence from the multi-dimensional multi-spectral camera and to:
- measure heart rate, oxygen saturation, blood flow per second, and blood pressure through image processing of the image sequence;
- generate a high-resolution image by superimposing low-resolution images included in the image sequence;
- track contour feature points in the high-resolution image to determine perfusion diffusion time;
- and calculate the blood pressure using diffusion vector mean, the heart rate, the oxygen saturation, and perfusion amplitude.
