摘要
采用高速摄像仪进行了热扰动环境下空气折射率分布变化引起光学成像变形的实验研究,获得了光学成像变形的总体规律。根据获得规律,在VC++软件平台上利用统计计算和数字图像处理对图像进行复原和测量曲线的修正,提高图像成像质量和测量的精度。
Research of optical image distortion caused by the change of the air＇s distribution of refractive index in a thermal disturbance field has been performed by the high-speed camera. It shows the characteristics of imaging distortion. According to the characteristics, the image is compensated by the method of statistic calculation and digital image processing on the software platform of VC＋＋ . Thus, the image quality is improved and the image measurement accuracy is increased.
