What is photogrammetry in architectural measurement?

Photogrammetry is a method that involves surveying and mapping the physical environment through photographic images and specialized software. By capturing photographs from multiple angles, photogrammetry allows for the extraction of accurate measurements and spatial relationships within a given area. The resulting data can be processed to create detailed 2D and 3D representations of topography, buildings, and other features.

This technique is particularly valuable in architecture and construction because it provides a cost-effective and efficient means of capturing complex geometries and site conditions without the need for extensive physical measurements. Photogrammetry is widely used for tasks such as creating site plans, analyzing building conditions, and facilitating the design process by offering precise visual and spatial data.

In contrast, using lasers to measure distances focuses on a different measurement technique known as laser scanning, which captures high-density point clouds for detailed analysis. While creating 3D models from physical sketches is relevant in architectural design, it does not encompass the measurement and mapping aspect of photogrammetry. Conducting soil analysis through photographs also does not relate to photogrammetry, as it involves different methodologies intended for subsurface investigation, rather than the analysis of spatial relationships through imagery.
