Posture estimation method and thermal massage mattress using the same

Abstract

The present invention provides a thermal massage mattress that can estimate the lying position of a person lying on the mattress using a whole body pressure measurement sensor and perform various treatments based on the estimated position of the person. The estimation method includes: a measurement step of measuring pressure at each location through a plurality of pressure sensors arranged in a two-dimensional matrix; a body pressure characteristic extraction step of extracting a pressure value (force), a pressure action area (area), a peak pressure location (peak pressure), and an area average pressure (mean pressure) as ratio variables from the measured pressure information of the two-dimensional matrix; and a position estimation step of estimating a lying position from the extracted variables through a position estimation algorithm.
