Method for acquiring characteristic points in the calibration of line structure-light sensor

  • Received Date: 05 Sep 2002

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