Positioning ball position determination method and device, electronic equipment and storage medium

The embodiment of the invention provides a positioning ball position determination method and device, electronic equipment and a storage medium. The positioning ball position determination method comprises the steps that spherical surface selection operation for a surface model composed of a plurality of triangular patches is received; in response to the spherical surface selection operation, performing spherical surface fitting according to the triangular patch corresponding to the selected position, and determining a sphere center coordinate corresponding to the fitted spherical surface to obtain a fitted positioning ball; and calculating a fitting error of the fitting positioning ball according to the parameter offset of the fitting positioning ball relative to the to-be-fitted positioning ball, and determining the fitting positioning ball with the fitting error smaller than a first preset threshold value as a target positioning ball. According to the scheme, the coordinates of the positioning ball on the
