The design of image networks plays a pivotal role in image-based 3D shape reconstruction and data processing, particularly when applying combined SfM/MVS methods. This paper presents an approach to designing and planning a multi-view images network for cultural heritage objects and sites based on a rough 3D model generated from public datasets of tourist images. Images for three famous cultural heritage buildings in India, namely Taj Mahal, Qutub Minar and Hawa Mahal, were used in this study to achieve the targeted goal. The results obtained confirmed that the Agisoft Metashape software made it possible to acceptably reconstruct the entire body of the studied structures. However, it the results showed when generating point clouds and 3D models of slender objects, i.e., the Qutub Minar, it is not possible to use only images acquired from the ground since most tourists wishing to correctly represent the shape take tilted images. For this reason, it is necessary to use videos or photos from UAVs. Generally, it can be concluded that the adopted approach in this study is a promising alternative for the conventional methods that are currently used for the shape reconstruction of cultural heritage objects and sites.

Advanced non-invasive remote sensing techniques, in conjunction with advanced digital technologies designed for the acquisition and comprehensive analysis of extensive datasets, hold substantial promise for significantly augmenting the capacities associated with the documentation of cultural heritage sites. This is especially crucial when it comes to preserving endangered cultural heritage. The main goal of this article was to demonstrate instances of non-invasive approaches used to catalog cultural heritage objectes and locations in Iraq. This investigation showcased a number of examples and employed a variety of contemporary data collection and processing techniques. These included digital close-range photogrammetry, Building Information Modeling (BIM), data from crowdsourced data, and findings derived from Mosul Project. As evident, reality underscores the presence of numerous perils endangering the preservation of tangible cultural heritage sites worldwide. Precious architectural marvels, artistic creations, and natural landmarks are at risk of permanent loss. Therefore, a prompt inventory process, along with the creation of precise digital models, ensures the protection, rescue, and potential reconstruction of these invaluable entities. The instances provided in this article, proved that the application of different digitization methods to Iraq's cultural heritage, can readily serve as a model for other endangered objects and sites.
