Summary

Photogrammetry is a technology used to measure objects and create detailed 3D models by analyzing multiple images of the same subject. It identifies common features across images, generating 3D point clouds and surface meshes that accurately represent the object’s shape and texture. This technique is beneficial for industries such as architecture, archaeology, geospatial mapping, entertainment, forensics, and industrial inspection due to its cost-effectiveness, precision, and non-destructive nature. It includes aerial photogrammetry for large areas using drones and close-range photogrammetry for smaller objects. An example includes using photogrammetry for detecting concrete cracks in infrastructure, combining it with AI for improved defect detection, showcasing its innovative applications in diverse fields.
