摘要

为了提高获取的三维模型精度

提出了光学和图像处理设备上消除电磁干扰信号的方法.首先运用幅度和频率筛选预测到电磁骚扰源是交流电机伺服器

然后通过计算得到设备接地回路中的共模骚扰电压确定耦合途径

最后依据各部分敏感度指数找到了骚扰接受敏感设备CCD摄像机.根据分析和计算

将该方法运用于多关节机械臂式三维信息获取系统中

取得了很好的效果.通过接地、隔离、滤波、屏蔽等方法逐个进行了符合设备电磁兼容规范的电磁兼容性设计

最终使设备符合了电磁兼容性规范的设计要求.

Abstract

In order to improve the precision of 3D model obtained

suggestions were made for the elimination of electromagnetic interference signals on optics and image processing equipment. The alternator servo was first identified as the electromagnetic interference source through amplitude and frequency screening

the coupling path was then determined by calculating the interference voltage in the equipment grounding loop

and the CCD camera was finally identified as the sensitive interference receiver through comparison of components' sensitivity indexes. Electromagnetic compatibility designs were made one after another against the equipment electromagnetic compatibility specifications through analyses and calculations and by grounding

isolating

filtering and shielding.
