基于LCD的相机标定精度及其误差分析

Precision and Error Analysis of LCD-Based Camera Calibration Method

    摘要
  • 摘要: 针对纯平液晶显示器(LCD)自身尺寸较小的问题,提出了新的标定影像拍摄方法。实验结果说明,该方法是有效可行的。另外,通过多组模拟数据和实际数据的分析说明,LCD相机的标定结果存在明显的系统误差,而借助逐步回归分析等方法则验证了这种系统误差主要来源于LCD自身的不平性,并且得出了定性和定量的结果。

     

    Abstract: A LCD-based camera calibration approach using special image shooting method is presented.The results show that the approach is very effective and feasible.Because of the great difference in depth precision between the simulation and actual experimentation,several possible error resources are carefully analyzed.By the stepwise regression analysis using simulated and actual data,non-planarity of LCD is validated.And when the non-planarity of LCD is corrected in the course of LCD-based calibration,precision can be further improved.
