| 摘 要： | 利用农药残留检测试纸显色区域的颜色值进行农药残留度测量,需对测量系统中的彩色CCD图像传感器进行标定,消除图像颜色失真.采用在拍摄环境中放置灰度块的方法,利用灰度块的RGB分量平衡性与灰度线性渐变性,同时对彩色CCD图像传感器进行白平衡和非线性校正.实验表明,该标定方法能够很好地还原颜色值,有利于农药残留检测的后续工作.

| Abstract: | It is necessary to calibrate the pesticide residue detector for obtain the real color values when detecting the pesticide residue based on the strips color reaction. The calibration was completed using the method that some gray patches whose RGB values are balanceable and changing linearly are photographed in the background of scene. Experiments results show that the calibration method can work well in color recovery which benefits the pesticide reside detection. |
