Examples
- 138 we are constrained to infer die level of any really ancient culture from the few artifacts that happen to have been preserved
8我们通常会受限于刚好被保存下来的制品，来断定任何古代文化的文明程度。 - In this thesis , the work on automatic alignment system is as follows : firstly , after the methods and optical systems for alignment whose are used commonly now are discussed , a new die leveling method based on auto - focus is presented for the flip chip bonder . auto - focus is completed by estimating from images ; die leveling is completed by focusing for several feature locations
本文针对倒装贴片机的自动对准系统开展了以下几方面的工作:首先在讨论了现有的对准方法和自动贴片机的对准光路系统基础上,针对贴片机实际应用环境,提出基于多点自动对焦的芯片调平方法。 - Today , the most advanced alignment methods have used the technology of machine vision and image proceeding , by which the feature marks on dies or substrate are recognized or measured , by which machine movement equipments are leaded to complete alignment . die leveling and auto - focus usually be completed before vision - based alignment of die and substrate
自动对准系统是自动贴片机中的关键组件之一,现阶段最先进的对准方法是利用机器视觉和图像处理技术来识别和测量微细标记特征,然后反馈给控制系统引导机械装置进行对准定位,在对准之前还必须对芯片进行“调平”以及实现“对焦”获得清晰的标记图像。 - As a result , just a set of imaging optical components , which used to merely complete alignment , now can be used for the three procedures ? die leveling , auto - focus , alignment . secondly , two vision - based optical systems for alignment are put forward . not only can high - resolution and high - quality images be gotten , but also straightforward hardware setup and good secular stability in the shop can be obtained
对本文所提出的光路结构方案中的成像镜组在光学自动设计软件zemax中进行了仿真和优化,成像镜组与所采用的高分辨率ccd相机和不同频率范围的led光源获得了很好的匹配,并在不同频带和视场获得了很好的像差平衡。
