High-resolution photogrammetry has become an influential non-invasive procedure of the non-erroneous 3D recreation of the conventional sculptural pieces, which has numerous benefits compared to the traditional casting and hand modeling procedures. The paper is a proposal of a high-fidelity photogrammetry system to document complex geometric characteristics of textures on the surfaces of iconic sculptures. The design incorporates the high-resolution imaging sensors, controlled illumination scenes, and optimized multi-angle image capture plans in order to provide maximum coverage and minimum reconstruction error. A systematic pipeline is adopted which includes camera calibration, feature detection by use of algorithms like SIFT, SURF and ORB and then an efficient feature matching, sparse reconstruction and dense point cloud construction. Different sculptural artifacts with different materials, size and different levels of texture are tested experimentally under different environmental conditions. The findings reveal that they are better, higher in accuracy, more intense in preserving the surface details and complete improvements in reconstruction than the traditional and baseline digital approaches. The suggested methodology ensures that human intervention is minimized but retains the cultural authenticity hence is very applicable in the digital archiving, restoration, online exhibition, and preservation of heritage. The paper will promote scalable, more accurate, and efficient 3D documentation methodologies in the cultural heritage preservation field.
