Ballistocardiogram analysis apparatus and method, and system for utilizing ballistocardiogram for vehicle using the same

A ballistocardiogram (BCG) analysis method, comprising:

• measuring a posture of an examinee;
• selecting a pattern depending on the measured posture;
• processing a signal by performing pattern matching using the selected pattern;
• and
• recognizing a biological condition of the examinee using results obtained at the processing the signal.

A ballistocardiogram (BCG) analysis apparatus, comprising:

• a posture measurement sensor for measuring a posture of an examinee;
• a pattern database (DB) constructed by standardizing BCG signals for a variety of individual postures of the examinee and extracting representative patterns;
• a BCG measurement unit for measuring a BCG signal of the examinee;
• a signal processing unit for processing the BCG signal measured by the BCG measurement unit so that the BCG signal matches a pattern of the pattern DB, thus calculating desired data;
• and
• a biological condition recognition unit for recognizing a biological condition of the examinee using a resulting value obtained by the signal processing unit.
