Abstract
A compression depth calculation system is configured to calculate the compression depth which is a magnitude of depression of the compressed object generated by the compression and includes a measuring apparatus to be mounted on the object, and a compression depth calculating apparatus is configured to calculate the compression depth on the basis of information from the measuring apparatus. The compression depth calculation apparatus calculates a coefficient of transformation on the basis of a second-order differential waveform created for the information acquired from a magnetic sensor and acceleration information acquired from an acceleration sensor, creates a displacement waveform of a compressed portion by multiplying the acquired information by the coefficient of transformation, and calculates the compression depth on the basis of the displacement waveform.
