High Precision Camera Calibration . Measurement precision is a fundamental performance in a vision metrology system, which is mainly restricted by following factors such as quality of source images, camera calibration method, accuracy of image characteristics extraction, object size and measurement distance, relative pose among cameras, random noise, and so on. The proposed method could be achieved by taking several photos on a specially designed calibration template that has diverse encoded points in different orientations.
