The invention provides a capsule endoscopy control method. The capsule endoscopy control method comprises the following steps: calling a starting position, controlling a motion control device to enable a capsule endoscopy to be in the starting position, calling a motion parameter, calling a terminating position, and controlling the motion control device according to a motion parameter to enable the capsule endoscopy to move to the terminating position in a helical motion mode, wherein the motion parameter comprises a motion thread pitch S and a motion angular speed w. The capsule endoscopy is controlled through a magnetic field to helically move within a preset track, the inner wall of the whole stomach is shot completely, and the leak detection caused by manual operations is avoided.
