The basic principle is that basic geometry shape of openings in the photo is revised; the image can't be distortion by use of projection reconstruction; the corrected image is exerted by open operation and close operation of gray-image; the shape of openings is gained lastly. The perimeter borderline of openings shape is extracted. The quantity of overbreak as well as underbreak is gained by comparing to extracted perimeter and designed perimeter. The same method is applied to other opening sections. Evaluation of overbreak as well as underbreak in the openings can be easily solved in the way of quantitative.

其基本原理是：对野外摄取的洞室的基本剖面形状进行几何校正，然后应用图像学中的投影重建方法使图像不失真，对修正后的图像实行灰度图像的开操作和闭操作运算，得到洞室的基本形状，然后用图像学中的边界提取技术提取洞室的周边界，与洞室的设计形状对比分析，得到洞室在该断面上的超欠挖方量，然后对其它断面采用同样的技术就可评价某一段或整个洞室的超欠挖数量，从定量的角度解决了工程中的超欠挖评价问题。

Chapter 4, established the vein of photographic work from the elaborative creation idea, translated the 3D stereoscopic vision into the 2D plane image, such image-writing reflected the creative form and the content, and practical creative thought by the straight photography. Showed each photographic work in the photography process with analyze the significance innermost feelings myself, which produces to the work attempt, as well as give a demonstration of perusable image in esthetics, society and cultural significance.

第四章从论述创作理念建立摄影作品的脉络，将3D的立体视觉转译成2D的平面影像，反映图像书写的创作形式与内容，并以实际的直接摄影表达创作的思维，说明每一幅摄影创作的拍摄过程与分析自己内心对作品企图产生的意义，以及显示影像在美学、社会与文化意义之阅读。

However, the reason that LCD can't fully take the place of the tube is mainly on the performance of color and motion image. Though LCD can greatly improve the Color Saturation up to NTSC 105%, LCD is limited on reaction time and continue LCD light source, which create image shape shadows while the image moves due to photogene.

而液晶显示器目前无法完全取代映像管的地方就在於色彩及动态影像的表现，虽然发光二极体已可大大改善色彩饱和度到达NTSC 105%，但液晶显示器受限於液晶的反应时间及液晶显示光源表现为持续方式，使在动态影像表现上因人眼的视觉停留的因素导致影像移动的边界上产生阴影。
