Summary:The invention discloses a three-dimensional alignment device for welding a photonic crystal fiber and a method thereof, wherein, mechanical transmission mechanisms of an upper three-dimensional motion V-shaped groove device (5) and a lower three-dimensional motion V-shaped groove device (14) of the device are connected with an alignment controller of a three-dimensional alignment controller and a clamp control unit (10), and a lower stress sensor (3) and an upper stress sensor (11) are connected with a stress sensor modulating unit (13); a double-sided holophote (12) of a micro-imaging unit (4) images a head face of the photonic crystal fiber and captures a geometric structure of the photonic crystal fiber which is positioned and identified by using a Hough transformation; and light emission and light receiving are achieved by coupling type light intensity determination units (1, 7, 8 and 15). The method comprises the following steps that: 1) the micro-imaging unit (4) acquires information of structure, and p
