1. A traffic hand signal detection system comprising:
an imaging unit configured to acquire a photographed image from a camera photographing a predetermined range;
an image classifier configured to classify an arm motion from the photographed image provided from the imaging unit by imparting a class;
a detection module configured to detect the arm motion from the photographed image classified by the image classifier and generate a traffic hand signal sequence as a combination of a plurality of numbers, each of the plurality of numbers representing a class of an arm direction image, the class of the arm direction image being defined in a direction toward which an arm is directed from the driver's point of view regardless of the direction a hand signal performer is looking; and
an analysis module configured to receive the traffic hand signal sequence as the combination of the plurality of numbers from the detection module and determine a type of a traffic hand signal.
