应用ＣＣＤ摄像和光学投影放大技术，配合数据采集和图像处理，对烟雾的宏观分布实施现场检测和监视。系统采用简易微分变换锐化烟雾图像边界，设计辛卜森数值积分软件计算烟雾截面面积，以校核ＣＣＤ像元累加结果，设计标准面积靶以标定全系统的精度，运用切比雪夫最佳逼近原理和拉格朗日插值多项式实施快速准确的工程测量与计算。
Application of CCD camera and optical projection magnification technology, with data acquisition and image processing, on-site detection and monitoring of the macro distribution of smoke. The system uses simple differential transformation to sharpen the smoke image boundary. The Simpson numerical integration software is designed to calculate the smoke cross-sectional area to check the accumulative result of CCD pixels. The standard area target is designed to calibrate the system-wide accuracy. By using Chebyshev’s best approximation Principle and Lagrange interpolation polynomial implementation of rapid and accurate engineering measurement and calculation.
