Abstract

We propose an elevation based approach to parkinglot structure analysis from aerial imagery. In contrastto image-based methods, the new approach treats parkedvehicles as 3-D microstructures and attempts to locatethem in the elevation domain. The STME (SurfaceTexture and Microstructure Extraction) system is applied tothe elevation maps to extract the 3-D microstructures. Ahybrid application of this system to both intensity and elevation maps results in a complete extraction of individual vehicles. Based on a comparison of texture exploitation techniques, a WCC weighted combination criterion algorithm is presented to generate a clean parking lot ground surface, which facilitates visualization andsimulation of parking lot activities with a high degree ofvisual realism.
