摘要：	State-of-the-art digital photogrammetric techniques for the acquisition of transportation-related information from digital are presented. Photogrammetric data collection can be performed using either aerial or close-range sensors. The difference between the two lies on the nature of data that can be acquired, in direct analogy to the resolution differences. The current state of technology for digital imagery acquisition permits the direct capture of digital close-range imagery, whereas digital aerial imagery is produced by digitizing analog diapositives. Thus, the availability of metric quality imagery in digital format is ensured, either directly or indirectly. Advancements in digital photogrammetric research are making feasible the transition from analytical to digital photogrammetric methods in transportation applications. This transition is characterized by automation and improved performance of traditional tasks. Furthermore, the use of imagery in digital format is offering the potential to radically modify tasks, products, and procedures. Digital photogrammetric techniques can be embedded within a transportation data-management environment, supported by additional information, and supporting decision making.
