高压地层微观模型系统中的背景校正

在微观地层模型显示系统中,地下图像存在摄像系统光轴不正、图像光照不均匀等问题,在后续的分割、提取界限等处理时,会因为背景不均匀而影响处理效果,因此需要进行背景校正。现利用曲面拟合和滤波的方法进行背景校正。对这两种方法做了详细的介绍,并给出实现的思路和方法,对两种方法做了分析和比较。曲面拟合可得到精确的背景校正模板,但是操作复杂,需要专业的熟悉曲面方程的人员来操作;滤波的方法不需要人工太多的干预,自动生成背景模板,可以对校正效果做人工比对,获得相对比较精确的校正背景模板,两者都能够满足实际应用需求。

Background Correction In High Press Stratum Micromodel

In stratum micromodel system,the underground-images always go with non-uniform background illumination and optical axis misregistration which can affect the efficience of image segmentation and image pickup,therefore,background correction is needed to avoiding the bad effect of background asymmetry.This system implemented surface fitting and image filter in background correction.The principles and implement steps of the two method are introduced,a comparison and analysis are made.Surface fitting can earn the exact background correction template,but the operation is complex,which need professional engineer who were familiar with surface equation;the image filter can earn the background correction template by computer,did not need people’s intervene.Both can meet the needs of practical application.
