Abstract
Based on the cross-ratio invariance theorem, a method for acquiring characteristic points in the calibration of linear-structure optical sensor was proposed. A larger number of high precision characteristic points were acquired with the designed calibration target. The problem that it is difficult to acquire a lot of high precision characteristic points was solved and the calibration precision was improved. The simulation results verify the feasibility of this method.
