According to the principles concerned with explosion radiation  the principle of measuring the time of remote explosion point and composition of measuring system is introduced. Use CCD to record the explosion radiation  DSP to process and record the high-capacity  high-speed video signals  and convert the exploding process examined by floating amplifier into digital signals. Besides  the article analyzes the composing and structural design of the log's optical system  principle of electric control and floating amplifier  dynamic range of the system  power analysis of the incident light  and how to improve the accuracy of measurement in great detail.   Real-time quality control on a smart camera (EI CONFERENCE) 会议论文  OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China Xiao C.; Zhou H.; Li G.; Hao Z. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 A smart camera is composed of a video sensing  high-level video processing  communication and other affiliations within a single device. Such cameras are very important devices in quality control systems. This paper presents a prototyping development of a smart camera for quality control. The smart camera is divided to four parts: a CMOS sensor  a digital signal processor (DSP)  a CPLD and a display device. In order to improving the processing speed  low-level and high-level video processing algorithms are discussed to the embedded DSP-based platforms. The algorithms can quickly and automatic detect productions' quality defaults. All algorithms are tested under a Matlab-based prototyping implementation and migrated to the smart camera. The smart camera prototype automatic processes the video data and streams the results of the video data to the display devices and control devices. Control signals are send to produce-line to adjust the producing state within the required real-time constrains.
