Imaging systems and methods compensate for wigwag movement of a C-arm fluoroscope to refine camera pose estimates. The methods involve computing a primary movement axis from samples of markers in fluoroscopic images of a fluoroscopic sweep of a structure of markers and processing the primary movement axis to obtain a secondary movement axis. The methods further involve aligning two-dimensional samples of each marker with the primary and secondary movement axes to obtain an aligned signal and determining a difference signal for a secondary component of the aligned signal.
