摘要

Graffiti rely on social instrumentation for its creation on spatial structures. It is questioned whether different mechanisms exist to transfer social and spatial hierarchies under a new model for better management. This study uses Postshot® to document the interaction between the “hard” infrastructure of a surface and the “soft” infrastructure of graffiti to survey the evolving urban fabric and to create a 3D documentation. Spatial configuration was reconstructed by linear filming and centered image-taking, for traditional photogrammetry tool using Zephyr® and a new AI tool using Postshot®. The result allows field graffiti application in a fast and intuitive documentation from an image-based generative approach.
