description: The work is dedicated to the investigation and development of a method for recovering the topology of a digital image of a hard copy document obtained using a camera. The work consists of three main sections. The first section includes a review and analysis of existing methods and algorithms used for creating digital document copies and recovering the topology of their images. Evaluating the performance of these algorithms allows identifying the features and shortcomings of existing document geometry recovery methods. The second section of the work explores various approaches to document detection and segmentation in images, aiming to select the optimal algorithm for solving the given task. Additionally, an algorithm based on computer vision methods is developed, utilizing perspective transformation and methods of approximation, linear, and cubic interpolation. The third section of the work is dedicated to evaluating the quality and accuracy of the developed method for image document geometry recovery, as well as comparing it with existing solutions. Based on the conducted research and obtained results, a conclusion is drawn regarding the applicability of the developed algorithm for solving the task of recovering the topology of a document image in digital form.
