Provided is a light source correction method for low-light detection, which relates to the technical field of remote detection. The light source correction method includes following steps: S1: determining whether brightness of a light source exceeds a predetermined value, and if the brightness of the light source exceeds the predetermined value, performing step S2; or if the brightness of the light source does not exceed the predetermined value, performing no operation; S2: driving a shielding plate located in front of a luminous flux detection board to rotate around a rotating shaft to obtain a luminous flux intensity on the luminous flux detection board; and S3: drawing a curve graph showing that the luminous flux intensity varies with a rotation position of the shielding plate, and calculating position information of the light source.
