MOTION ANALYSIS SYSTEM AND MOTION ANALYSIS METHOD
First Claim
1. A motion analysis system comprising:
- first to N-th (N is an integer equal to or larger than
2) sensor units which includes a reception unit of a synchronization signal and a sensor and is attached to an object;
an analysis unit which obtains a plurality of items of sampling data output from the first to N-th sensor units, to analyze a motion of the object;
a synchronization signal sending unit which transmits a first synchronization signal group including N first synchronization signals in order from the first sensor unit to the N-th sensor unit, and transmits a second synchronization signal group including N second synchronization signals in order from the N-th sensor unit to the first sensor unit, with respect to the reception unit which is provided in the first to N-th sensor units; and
a reference synchronization signal generation unit which generates a reference synchronization signal which is to be a reference with respect to the first to N-th sensor units, based on the first synchronization signal group and the second synchronization signal group received by the reception unit which is provided in the first to N-th sensor units.

Abstract
A motion analysis system includes first to N-th (N is an integer of 2 or more) sensor units which is attached to an object, an analysis unit which obtains a plurality of items of sampling data output from the sensor units, to analyze a motion of the object, a synchronization signal sending unit which transmits a first synchronization signal group including N first synchronization signals in order from the first to the N-th sensor unit, and transmits a second synchronization signal group including N second synchronization signals in order from the N-th to the first sensor unit, with respect to sensor unit, and a reference synchronization signal generation unit which generates a reference synchronization signal which is to be a reference with respect to the first to N-th sensor units, based on the first and second synchronization signal groups received by sensor unit.
