1. A method for determining a reference line, comprising:
obtaining at least two original images, the at least two original images corresponding to first spatial position information;
determining a composite image based on the at least two original images, the composite image corresponding to second spatial position information;
determining a composition relationship between the at least two original images; and
determining at least one reference line based on the composition relationship between the at least two original images, the first spatial position information, and the second spatial position information, wherein the at least one reference line displays a positional relationship between one of the at least two original images and a reference image on the composite image, wherein the determining at least one reference line comprises:
determining a first reference line based on the first spatial position information and the second spatial position information;
obtaining, based on an objective function, a transformation matrix by performing at least one of translation or rotation operation to the first reference line; and
obtaining a second reference line by correcting the first reference line based on the transformation matrix.
