由于当今的技术，创新的工具能够增加我们对历史古迹的了解，在文化遗产的保护和评估领域。这些工具旨在帮助专家创建、丰富和共享有关历史建筑的信息。在各种文献资料中，照片包含了关于形状和颜色的高度细节。随着图像分析和基于图像的建模技术的发展，大量的图像可以在空间上面向数字实体模型。由于这些原因，数码照片被证明是一个易于使用，负担得起的和灵活的支持，遗产文件。本文提出了，在第一步中，在一组面向空间的照片（其在空间中的位置和方向自动估计）的2D/3D语义注释的方法。在第二步中，我们将专注于一种方法，用于显示这些注释上的新图像采集的移动的设备在原位。首先，基于图像的自动重建方法通过处理大图像集来产生3D信息（特别是3D坐标）。然后，对图像进行语义注释，并且过程使用先前生成的图像固有的3D信息进行注释传输。因此，该协议提供了一种简单的方法来一次而不是一个接一个地对大量图像进行精细注释。由于这些图像注释是3D信息直接固有的，因此它们可以存储为3D文件。为了在屏幕上显示与建筑物相关的信息，用户在原地拍照。图像处理方法允许在已经定向的大图像库内估计该新照片的定向参数。然后，注释可以被精确地投影到定向图片上并发送回用户。以这种方式，可以建立从初始采集到现场可视化的信息连续性。
Thanks to nowadays technologies, innovative tools afford to increase our knowledge of historic monuments, in the field of preservation and valuation of cultural heritage. These tools are aimed to help experts to create, enrich and share information on historical buildings. Among the various documentary sources, photographs contain a high level of details about shapes and colors. With the development of image analysis and image-based-modeling techniques, large sets of images can be spatially oriented towards a digital mock-up. For these reasons, digital photographs prove to be an easy to use, affordable and flexible support, for heritage documentation. This article presents, in a first step, an approach for 2D/3D semantic annotations in a set of spatially-oriented photographs (whose positions and orientations in space are automatically estimated). In a second step, we will focus on a method for displaying those annotations on new images acquired by mobile devices in situ. Firstly, an automated image-based reconstruction method produces 3D information (specifically 3D coordinates) by processing a large images set. Then, images are semantically annotated and a process uses the previously generated 3D information inherent to images for the annotations transfer. As a consequence, this protocol provides a simple way to finely annotate a large quantity of images at once instead of one by one. As those images annotations are directly inherent to 3D information, they can be stored as 3D files. To bring up on screen the information related to a building, the user takes a picture in situ. An image processing method allows estimating the orientation parameters of this new photograph inside the already oriented large images base. Then the annotations can be precisely projected on the oriented picture and send back to the user. In this way a continuity of information could be established from the initial acquisition to the in situ visualization.
