摘要
针对相机标定问题设计了一个非线性优化模型,利用最小二乘原理检验了模型的精度和稳定性,最后建立超定方程确定了两相机之间的相对位置.模型充分考虑了相机成像中得诸多因素,结合其中的线性和非线性关系,建立了非线性优化模型.数值结果表明,模型合理,具有广泛的适用性.
This paper was designed a nonlinear optimization model for camera calibration problem.We tested the accuracy and stability of the model,and finally we establishment overdetermined equations to determine the comparative position of the two cameras.The model also considered many factors in the camera imaging.We obtained the linear and nonlinear relations which were established nonlinear optimization model.The numerical results showed that the model was very reasonable,and has broad applicability.
