| 摘要: |
| 针对传统摄像机标定中由于像差等非线性因素的影响造成结果精度和稳定性不高且算法复杂的特点，提出了用4层前向神经网络模型变易摄像机横纵向有效焦距的方法。给出了摄像机标定结果和用标定后的摄像机进行三维立体测量的结果，并与传统方法作了对比。结果表明，基于神经网络的摄像机标定方法可以获得比传统方法更高的精度和稳定性。 |

| Abstract: |
| The traditional calibration method is always imprecise, unstable and computed costly because of the nonlinear effect lead by lens distortion. A new camera calibration method of varying effective focal length by neural network model is presented. Both calibration result and 3D measurement result show that the new method achieves more precision and stable result than classical method does. |
