An object of the present invention is to provide a method, an apparatus and a
system for automatically recognizing motions and actions of moving objects such
as humans, animals and machines.
Measuring instruments are attached to an object under observation. The
instruments measure a status change entailing the object's motion or action and
to issue a signal denoting the measurements. A characteristic quantity extraction
unit extracts a characteristic quantity from the measurement signal received which
represents the motion or action currently performed by the object under observation.
A signal processing unit for motion/action recognition correlates the extracted
characteristic quantity with reference data in a database containing previously
acquired characteristic quantities of motions and actions. The motion or action
represented by the characteristic quantity with the highest degree of correlation
is recognized and output.
