The invention discloses an infrared gesture recognition method and apparatus based on region sequence reconstruction. The method comprises the steps of establishing a coordinate system, normalizing distances between at least four arranged infrared distance measuring sensors and the X axis and the Y axis, and determining coordinates of each sensor; measuring the distance between a hand of a user and each infrared distance measuring sensor when the hand of the user is detected to enter in effective ranges of the infrared distance measuring sensors; calculating coordinates of the hand of the user; and determining the quadrant where the hand of the user is located according to the coordinates of the hand of the user, and recognizing the gesture type of the user according to variation of the quadrant. According to the infrared gesture recognition method and apparatus based on region sequence reconstruction, three-dimensional motion coordinates of the gesture can be reproduced according to arrangement relationship of the infrared sensor array and infrared distance measuring values, the regions through which the gesture passes are determined to recognize the gesture motion, the regions are determined without being influenced by abnormity of individual points, anti-interference capability is high, and recognition rate is high.
