摘要：
The present invention relates to a stick provided with a Braille block pattern recognition system for a visually impaired person and, more particularly, to a stick provided with a Braille block pattern recognition system for a visually impaired person with which a dot-type or line-type Braille block that is installed on a pedestrian walkway for guiding visually impaired persons is recognized by a camera, a pattern of the recognized Braille block is analyzed, the analyzed pattern of the Braille block is transmitted to the visually impaired person in the form of a sound, and the visually impaired person is informed of a detected obstacle in the direction of his or her walking so that the visually impaired person can walk to his or her destination with ease. To this end, the present invention provides a stick provided with a Braille block pattern recognition system for a visually impaired person including: a camera unit for imaging and recognizing a Braille block a Braille block pattern analysis unit performing image processing on the Braille block recognized by the camera unit and transmitted, analyzing the pattern of the Braille block, and then transmitting the analyzed pattern of the Braille block in the form of a sound signal a sound output unit including a headset receiving and outputting the sound signal transmitted from the Braille block pattern analysis unit an ultrasonic distance detection sensor for detecting the presence or absence of an obstacle in a progress direction an obstacle distance analysis unit calculating the distance to the obstacle by processing an obstacle detection signal transmitted from the ultrasonic distance detection sensor, the obstacle distance analysis unit transmitting a vibration signal in a case where the obstacle is within a predetermined distance input in advance and a vibration signal receiving unit receiving the vibration signal transmitted from the obstacle distance analysis unit and outputting it in the form of vibration.본 발명은
