Provided is a bending angle calculation method capable of saving a worker time and effort. The bending angle calculation method includes: an image capturing step (S) of capturing an image of a pipe in which a first pipe and a second pipe are joined together by a joint; a derivation step (S) of deriving, from the image, a laying direction straight line corresponding to a laying direction of the pipe; and a calculation step (S) of calculating, as a bending angle at the joint, a crossing angle between a laying direction straight line of the first pipe and a laying direction straight line of the second pipe.
