Study conducted to verify that commercial hardware and software can be used to construct accurate three-dimensional models via the use of a virtual environment and from 3-D models created with four cameras. A Remote Accessibility Assessment System (RAAS) that uses three-dimensional (3-D) reconstruction technology was developed for the study. The RAAS was created to allow clinicians to assess the wheelchair accessibility of environments from a remote location. The RAAS uses commercial software to construct three-dimensional virtualized environments from photographs. The researchers used a standard digital camera and PhotoModeler software in the system. The researchers developed custom screening algorithms and instruments for analyzing accessibility. Preliminary analyses indicated the system’s effectiveness in evaluating the wheelchair accessibility of a given environment. Implications for future research are discussed.
