This Small Business Innovation Research (SBIR) Phase I research project seeks to develop a low-cost high-speed automatic book scanner to digitize vast libraries of bound printed matter. Despite the ubiquitous use of computers to create modern publications, the majority of literature in circulation remains exclusively outside the digital domain. This renders large volumes of books to be inaccessible to search engines and digital libraries. The vast majority of books that are now converted from the printed page to digital format are scanned manually. This is a slow, tedious, and costly process that is hinders the ability to scan the millions of books by several companies that provide books and content in digital form. For people with physical disabilities, the digital version of books can enable them to reach beyond the mechanical limitations of page turning and the visual limitations of small fixed-sized fonts. Digitizing traditional books is also of practical importance for legal fair-use purposes by students, researchers, and all people who yearn for a digital library that can benefit from portability and search engines. It is anticipated that legal personal use of book scanning by corporations, libraries, government agencies, and high-end consumer markets will have broad impact on education, research, and commerce. The objective of this project is to develop a robust solution at less than one tenth the price of competing products. The proposed device addresses two core problems in book scanning -- automatic page turning and page flattening. A novel turnstile design is introduced to hold the book open flat, as well as to move a page from one side of the book to the other. The analysis of bending stiffness, friction, and contact pressure will enable the input to the image acquisition system to fuse input images having minimal distortion. Feasibility will be determined by measuring the registration (alignment) error of the imaging system and determining if sub-pixel accuracy is achieved in registering multiple page images together during the image fusion operation.

这个小型企业创新研究（SBIR）第一阶段的研究项目旨在开发一种低成本的高速自动图书扫描仪，以扫描大量的装订印刷品。尽管计算机被广泛用于制作现代出版物，但流通中的大多数文学作品仍然完全处于数字领域之外。这使得搜索引擎和数字图书馆无法访问大量书籍。现在绝大多数从印刷页面转换为数字格式的书籍都是手动扫描的。这是一个缓慢、繁琐和昂贵的过程，阻碍了几家以数字形式提供书籍和内容的公司扫描数百万本书籍的能力。对于身体残疾的人来说，数字版的书籍可以使他们超越翻页的机械限制和小型固定字体的视觉限制。传统书籍的数字化对于学生、研究人员和所有渴望数字图书馆的人来说，也具有法律的合理使用的实际重要性，因为数字图书馆可以从便携性和搜索引擎中受益。预计公司、图书馆、政府机构和高端消费者市场对图书扫描的法律的个人使用将对教育、研究和商业产生广泛的影响。该项目的目标是开发一种强大的解决方案，价格不到竞争产品的十分之一。该设备解决了图书扫描中的两个核心问题-自动翻页和页面展平。一个新颖的旋转栅门设计被引入，以保持书打开平面，以及移动一页从一边的书到另一边。弯曲刚度、摩擦力和接触压力的分析将使得图像采集系统的输入能够融合具有最小失真的输入图像。可行性将通过测量成像系统的配准（对准）误差并确定在图像融合操作期间将多个页面图像配准在一起时是否达到亚像素精度来确定。
