Photogrammetric modelling, a widely used technique for reconstructing 3D models from photographic data, relies on achieving high geometric accuracy to minimize post-processing efforts. This study proposes an enhancement to the photogrammetric reconstruction workflow through the introduction of the Boundary Marking Technique. By visibly marking the edges surrounding object surfaces, this method aims to improve edge definition and overall reconstruction quality. The technique was applied to both metal and plastic objects of identical geometry. 3D models were generated using close-range photogrammetry for both marked and unmarked versions, and deviation analyses were conducted against their CAD references. A total of 16 analyses comprising one 3D and three 2D per object were performed using computer-aided comparison tools. Results indicate that the Boundary Marking Technique significantly enhances geometric accuracy, particularly along edges and adjacent surfaces, ultimately improving model topology and dimensional fidelity across the entire reconstruction.
