The invention relates to a three-dimensional reconstruction detection system for the inner surface of a pipeline. The method comprises the following steps: acquiring camera parameters; acquiring a number set of a plurality of light planes; the number set comprises a plane parameter, a plane number, a plane width and a plane center distance; projecting the plurality of light planes to the inner surface of the to-be-detected pipeline, and collecting the inner surface to obtain a light stripe image; extracting a center line coordinate of each light stripe in the light stripe image to obtain a center line coordinate set; obtaining a stripe center distance of each light stripe based on the center line coordinate set; obtaining a stripe number of each light stripe based on the stripe center distance, the plane center distance, the plane width and the stripe width; and performing three-dimensional reconstruction based on the camera parameter, the light stripe image, the plane parameter, the stripe number and the pla
