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.

一种从书籍中提取三维信息的方法的开发：首先，开发了一个应用系统，该系统从水平放置的书籍表面的数字图像中获取全局表面信息和来自废纸弯曲和旋转的精确三维信息。光度立体法存在的问题是：（1）不能将纸张表面的光学特性近似为完全散射面; (2)由于在书页边界处存在多次反射、阴影等影响，无法很好地解决这一问题，因此提出了一种新的方法来获取更好的三维信息。一种高分辨率图书信息存档方法的研究：目前数码相机的分辨率约为2000像素× 2000像素，因此在存档较宽的图书时，无法获得足够的分辨率。为此，提出了一种将多幅分离的图像进行联合收割机拼接的方法，即对重叠区域采用立体匹配的方法进行三维信息的提取，对其他区域采用前一种方法得到的上下两层三维信息进行插值得到三维信息。最后，提出了一种图书图片数字化的方法。该方法与数字化字符时的方法基本相同。提出并发展了涂料强度模型。该方法针对善本表面的反射特征变化较大，三维变化较小的特点，具有较强的鲁棒性。这种方法是基于这样一个事实，即当时只有几种油漆，从化学原因来看，几乎没有覆盖画。该方法考虑了这些性质，得到了较好的结果.
