We propose novel methods for both techniques to monitor the surrounding area of a vehicle. For fisheye camera calibration, we proposed a novel photogrammetric calibration method using planar calibration objects together with a distortion model based on the design of the fisheye lens. By minimizing the residual error between observed and predicted image coordinates of feature points, a set of camera parameters that best describe the imaging process of the camera can be obtained.

在鱼眼摄影机校正中，我们提出基於摄影校正法的创新的校正方法，其中利用平面校正物进行鱼眼摄影校正，并以视野失真模型(field-of-view distortion model)作为鱼眼失真模型，透过降低摄影机校正误差进行非线性的摄影机参数最佳化，由已校正的鱼眼摄影机所拍摄的影像皆可经由失真校正将鱼眼影像还原至透视投影影像。

It is impractical in laboratory calibration with this infinite single wire which can be replaced by an N-turn coil. According to the equal ampere-turn principle, it is feasible to calibrate the high current range of the clamp ammeters with low current. However, the calibration coil brings new uncertainty into the calibration.

根据等安匝原理，实验室常用多匝校验线圈代替单根导线对钳型表进行校准，如此只需小电流即可对钳形表大电流量程进行校准，但是校验线圈这种校准方法会引入新的测量不确定度。
