Reference Stars: Star with known position and/or magnitude, that are used to find the plate constants and photometric calibration of an image.
参考星：已知位置和/或星等的恒星，用于确定图片的底片常数和光度校准。
However, there is less method on how to solve the calibration on large complex screen. We summarize recent popular methods on the geometry calibration and photometric calibration.
对于如何在复杂显示表面，例如异型屏幕、大规模异型屏幕上面如何进行图像校正，相关的工作还比较少。
