The Fresnel lens in the optical receptor spotlights the headlamp beams to form their image at the 1-meter distance between the optical receptor and headlamps. CMOS camera as an image sensor, takes the photos of their images, which are captured by VG-M201, The application of some digital image processing techniques to these images, such as edge-picking up、 least-square fitting-curve algorithm, is to calculate the offset position/angle of optical axis of the high beams and the nodical offset of the unsymmetrical facular light and shade cut-off line of the low beams.

系统的图像采集工作是利用受光箱中的菲涅耳透镜在1米的测量距离上聚合前照灯灯光，由CMOS摄像头作为图像传感器件，照入灯光远光光斑和非对称近光图像，由嵌入式处理器对捕获的图像运用边缘提取、最小二乘法拟合曲线等数字图像处理技术计算出远光主光轴偏移角度以及非对称近光光斑明暗截止线拐点的偏移，实现了前照灯近光非对称光斑的自动测量。

It is found that the damage of the lines is mainly aroused by heat effect and electric force generated by impulse current circuit, and the effect is different between different current value and different lines. The steady state and transient state shielding efficiency of plate shielding cabin with metal silk net window and without window are measured, and the influence of window to shielding efficiency is analyzed. The result shows that the steady state shielding efficiency rises with frequency.

试验结果表明屏蔽室的稳态屏蔽效能基本上是随着频率的升高而变大，两种带合金丝网玻璃窗的金属板屏蔽小室的在10kHz以下时稳态屏蔽效能有15dB左右，在20kHz以上时各点稳态屏蔽效能都可以达到20dB以上，丝网玻璃窗对离窗近的测量点的屏蔽效能影响较大，而对离窗远的测量点影响较小。

Finally, the splats are rendered from far to near by using elliptical weighted average filtering.

首先根据构造的移动最小二乘曲面计算采样点的表面几何属性，然后根据协方差分析确定点元在其切平面上的椭圆表示，最后采用椭圆加权平均滤波从远到近单遍绘制各点元。

During the process, the whole position errors on the plane were measured by using the equipment that can only measure a small field. The positional errors on the entire plane table of CNC machine tools were obtained by measuring the error of the basic postion near the original point.

该方法以距离机床坐标原点较近的点（该点的误差直接通过测量仪器获得）为基点，从而获得离机床坐标原点较远位置点的误差，依此类推，最终获得整个机床平面上位置点的误差信息。
