Summary:The invention discloses a tracker parameter real-time calibration method and system, and the method comprises the steps: taking a certain point in a world coordinate system as a fixed point, taking the fixed point as a reference, taking the original point of a left camera image space coordinate system of a tracker as the original point of a tracker coordinate system on numerical calculation, and obtaining the original parameters of the tracker; a calibration rod is fixed under the visual field of the tracker, and the distance between the mark point pairs on the calibration rod is obtained; measuring the three-dimensional measurement coordinates of each mark point on the calibration rod; and establishing a calibration model according to the change type of the external parameters of the right camera, and carrying out real-time calibration on the external parameters of the right camera of the tracker according to the distance between the mark point pairs and the measurement coordinates of the mark points based o
