Vision measurement system high-precision calibration plate matched with light pen measuring instrument and calibration method

The invention discloses a vision measurement system high-precision calibration plate matched with a light pen measuring instrument and a calibration method, and belongs to the technical field of photogrammetry (close shot), and the vision measurement system high-precision calibration plate comprises a calibration plate, a positioning hole and a ruby pen point; each calibration plate is provided with four positioning holes, and the diameter of each positioning hole is equal to the diameter of a ruby pen point of a light pen measuring instrument. The hole depth of the positioning hole is equal to the radius of a ruby pen point of the light pen measuring instrument; the adjacent positioning holes are symmetrical about the center line of the calibration plate, and the two positioning holes on the same diagonal line of the calibration plate are symmetrical about the intersection point of the diagonal lines of the calibration plate. The method has the advantages that the high-precision calibration ...
