摘要：FIFEDOM (Frequent-Image-Frames Enhanced Digital Ortho-rectified Mapping) is a multidisciplinary ongoing research project aiming to provide low-cost and high information content digital mapping by developing an intelligent digital airborne image acquisition strategy, and novel image processing techniques. In particular, FIFEDOM is designed to exploit the high degree of overlapping of the digital aerial imagery to generate accurate map products. FIFEDOM utilizes high-overlap digital image acquisition to provide multiple-look-angle reflectance for each pixel in a scene. The FIFEDOM project concentrates on four technology areas, Image Acquisition System and Sensor Calibration, Radiometric Balancing, Digital Surface Model (DSM) generation, and Bi-directional Reflectance Distribution Function (BRDF) model extraction. This paper emphasizes the FIFEDOM DSM module. It introduces an innovative, and breakthrough methodology for automated DSM generation. This is achieved through utilization of multi-view, multi-frame highly overlapped digital images. This capability improves the result significantly by generating a very dense, high quality, and reliable Digital Surface Model. The paper also discusses sensor calibration and radiometric-balancing, as they are prerequisite steps for the successful completion of the DSM task
