摘要
目的:探讨干式激光相机图像校准的要点及其意义。方法:应用DPX7PCTOOL图像校准软件对FUJI DRYPix7000干式激光相机进行调试,反复调节SarMaker曲线,测试最佳图像质量时的最大密度值(Dmax)和最小密度值(Dmin)。结果:经过反复调试,使图像质量满意的胶片的Dmax是290,Dmin是22,对SarMaker曲线进行了细微调节,最后设置5点的值。结论:干式激光相机经过严格的图像校准调试及日常的维护、保养能获得稳定的高质量图像。
Objective:To explore the correction of pictures for the dry laser imager.Methods:The FUJI DRYPix 7000 dry laser imager was tested by using the picture adjusting software of DPX7 PC TOOL.The SarMaker curve was repeatedly adjusted,and the maximum and minimum density were measured by this system.Results:The maximum and minimum density measured by this system were 290 and 22,respectively.The SarMaker curve was set up 5 degree point values.Conclusion:Accurately correcting pictures and daily maintaining for the dry laser imager could ensure the high quality of pictures.
