项目摘要

Development of a method for archiving of 3-dimensional information from Book :At first, an application system is developed, which gets from digital image archived from the book surface located horizontal, a global surface information and precise 3-D information coming from bending and rotation of used paper. It has many problems when using photometric stereo method that(1) It can not be approximated that optical characteristic of paper surface is complete scattering surface.(2) It can not be solved the problem because of influence of multi-reflection, shadow and so on, at the boundary between pages.So a new method to get better 3-D information has been developed.Development of a method for archiving high-resolution information from book :Currently the resolution of digital camera is approximately 2000 pixel by 2000 pixel, so when archiving wider book, it can not be gotten sufficient resolution. So, a method to combine gotten several separated pictures, has been developed,The method is that, for the overlapped region, stereo matching method is applied for getting 3-D information and for other region, the 3-D information is gotten by interpolating from uper and lower 3-D information which are gotten previous method.Development of a method for archiving from picture in the book :At last, a method for digitizing pictures in the book, has been developed. The method is basically the same as when digitizing characters. The paint-strength model is proposed and developed. This method is robust for that, the reflection characteristics of the surface of the rare book are various, including small 3-D variance. This method is based on the facts that at that time there were only few kind of paints and from the chemical reason there were few overlaid painting. The method is concerned such properties, and gets better results.

开发了一种从书籍中归档三维信息的方法：首先，开发了一个应用系统，该系统从位于水平的书籍表面存档的数字图像中得出，这是全球表面信息和精确的3-D信息，来自二手纸的弯曲和旋转。在使用光度计算方法时，（1）纸表面的光学特征是完全散射的表面。（2）由于多反射，阴影的影响，在页面之间的边界上的影响，无法解决问题。到2000像素，因此，当归档更广泛的书时，它就无法获得足够的分辨率。 So, a method to combine gotten several separated pictures, has been developed,The method is that, for the overlapped region, stereo matching method is applied for getting 3-D information and for other region, the 3-D information is gotten by interpolating from uper and lower 3-D information which are gotten previous method.Development of a method for archiving from picture in the book :At last, a method for digitizing pictures in the book, has been developed.该方法基本与数字化字符时相同。提出并开发了油漆强度模型。此方法对此是可靠的，稀有书籍表面的反射特性各不相同，包括小的3-D方差。这种方法基于以下事实：当时只有很少的涂料，而从化学原因中，几乎没有覆盖的绘画。该方法涉及此类属性，并获得更好的结果。
