[0002] In the rapid development process of digital office and information management, the graphic and text information collection and input device, as a key tool for data acquisition and processing, has become increasingly important. The information collector, as a professional device integrating optical imaging, image processing, and data conversion technologies, is mainly used to convert physical information such as paper documents and pictures into editable and storable digital formats, and is widely used in multiple fields such as archival digitization, library material arrangement, and enterprise document management. It captures detailed information such as text and images on the document through high-precision scanning or shooting technology, and then uses software algorithms for recognition and conversion, greatly improving the efficiency and accuracy of information processing.

[0003] However, when processing documents with severe wrinkles, the current information collectors on the market generally have the problem of low accuracy in information input. Wrinkles not only change the optical properties of the document surface, resulting in blurred or distorted imaging, but also interfere with the accurate recognition of text lines and character boundaries by image processing algorithms, thereby affecting subsequent text recognition and image correction effects. This problem not only increases the workload of information input, reduces the overall efficiency, but also may lead to inaccurate data due to recognition errors, affecting subsequent information analysis and decision-making.
