Object recognition system and object recognition method

An object recognition system comprising:

• an image capturing unit disposed in a site, the image capturing unit capturing an image sequence of the site, wherein at least one object exists in the image sequence and the at least one object comprises a target object;
• a motion sensing module disposed on the target object, the motion sensing module comprising a transmitter and a motion sensor, the transmitter being electrically connected to the motion sensor, the motion sensor selectively driving the transmitter to transmit a plurality of wireless signals according to a plurality of motion states of the target object;
• a receiver disposed in the site, the receiver receiving the wireless signals;
• and
• a processor coupled to the image capturing unit and the receiver, the processor analyzing the image sequence to obtain at least one first motion state curve corresponding to the at least one object, the processor receiving the wireless signals from the receiver and generating a second motion state curve corresponding to the target object according to the wireless signals, the processor comparing the second motion state curve with the at least one first motion state curve and determining whether to recognize the at least one object corresponding to the at least one first motion state curve as the target object according to a correlation between the at least one first motion state curve and the second motion state curve.
