1. A calibration method for structure parameters of a structured-light vision sensor, comprising the steps of:

  • a. setting up coordinate frames of a camera and an image plane;

    b. setting up a target coordinate frame, acquiring images of a planar target which is used to calibrate the structure parameters of the sensor, and finding coordinates in the camera coordinate frame of stripes projected by structured-light on the planar target; and

    c. acquiring coordinates in the camera coordinate frame of the stripes projected by structured-light on the target plane multiple times, and fitting a structured-light equation according to the acquired coordinates.
