The invention discloses a laser communication terminal capture view field rapid calibration method based on a two-dimensional scanning light beam, and the method comprises the steps: S1, employing an upper computer to set the working mode of a detected space laser communication terminal as a gray centroid method detection mode, setting the working parameters of a capture CCD, and configuring the parameters to be in an initial state; s2, a semiconductor laser is started to emit a laser light source, and the detected space laser communication terminal starts to capture an optical signal along with the laser light source; s3, controlling the two-dimensional translation guide rail to do translation motion in the positive and negative directions of the X axis through the upper computer; s4, controlling the two-dimensional translation guide rail to do translation motion in the positive and negative directions of the Y axis through the upper computer; s5, a capturing view field is converted according to the moving d
