Resumen
Forensic terrestrial photogrammetry is one of the most valuable and low-cost resources of spatial data available today. Due to theephemeral crime scene characteristics, these photographs can often capture information that is never to be seen again. This paper presents a noveltyapproach for the documentation, analysis, and visualization of crime scenes for which only a single perspective image is available. The photogram-metric process consists of a few well-known steps in close-range photogrammetry: features extraction, vanishing points computation, camera self-cali-bration, 3D metric reconstruction, dimensional analysis, and interactive visualization. Likewise, the method incorporates a quality control of thedifferent steps accomplished sequentially. As a result, several cases of study are presented in the experimental results section in order to test their via-bility. The full approach can be applied easily through the free software, sv3DVision, which has been evaluated by a number of police officers, foren-sic scientists, and forensic educators satisfactorily
