CCD打靶系统设计方案

文 摘

CCD全称为电荷藕合器件，由于CCD具有非接触性测量、分辨率高等方面的特点，因此CCD器件在物体外型测量、表面检测、图像传真、智能传感等方面得到了广泛的应用。另外，CCD测量速度快，所以不仅可用于静态测量，还可用于动态在线检测，因此CCD技术在线检测系统中应用也越来越多。现代加工技术发展迅速，加工精度不断提高，相应的对检测设备也提出了新的要求，如高精度，在线检测等，新技术，新工艺，新项目对大直径尺寸高精度测量技术提出了越来越高的要求。在当今国内工业中对直径的测量大多还是采用千分尺等落后的接触式的方法，不但效率不高而且精确度不够。针对工业中用千分尺人工对工件直径测量的落后方法，利用线阵CCD对直径实现精密测量的系统进行了设计。该系统基于光学系统无接触性测量的基本原理，运用光学测量的理论和一般方法，设计并讨论了在实际运用中存在的问题及解决办法。 为了探索CCD图象传感器在尺寸检测方面的应用性能、特性参数以及相关测控系统硬件系统的设计特点，从而为今后研制基于线阵CCD的宽范围尺寸测量系统作好理论和实验准备方案:光学部分的内容。机械部分主要是相关传感器的支撑结构设计 。电路控制部分主要有CCD芯片选择、CCD输出信号的处理、单片机数据采集及处理等。 关键词CCD传感器 ，二值化,单片机

English Abstract

All called charge coupled device CCD, due to CCD non-contact measurement with high resolution and the characteristics, so CCD device object shape measurement, surface inspection, image fax, intelligent sensing and so on have been widely used. In addition, CCD high speed, so not only can be used for static measurement, but also for dynamic line detection, the CCD technology online detection system applications are increasing. The rapid development of modern processing technology, continuously improving processing precision, corresponding to the test equipment also made new demands, such as high-precision, on-line detection, new technologies, new techniques, new projects on the large diameter of the proposed high-precision measurement technology more to the higher requirements.

In today the domestic industry, or most of the diameter measurement using micrometer and other backward-contact method, the efficiency and accuracy is not high enough. Micrometer used for industrial labor behind the workpiece diameter measurement method using linear array CCD to achieve precise measurement of the diameter of the system design. The system is non-contact optical system based on the basic principle of measurement, using optical measurement methods of the theory and the general design and discusses the practical application of problems and solutions. In order to explore the CCD image sensor in the size of the appl
