摘要:Digital photogrammetric sensors offer a great potential for automatic, quantitative processing and utilization of image radiometry. The photogrammetric production lines with efficient, repetitive data collection, rigorous geometric processing, great geometric accuracy and reliability, high spatial resolution, and stereoscopy with large observation angles is an appealing and practical environment for the accurate radiometric processing and utilization. European Spatial Data Research (EuroSDR) organization launched a collaborative investigation project on radiometric aspects digital photogrammetric airborne images in May 2008. This article gives a brief summary of results of a query to data providers and users that was carried out in the framework of the project. The results showed that improvements are requested on the entire process, including sensors, calibration, data collection, data post- processing and data utilization. The fundamental problems are the insufficient information of the radiometric properties of photogrammetric sensors and processing of the image data, and inadequate radiometric processing lines. The basic products requested by users are true color images and reflectance images. The query suggested that in order to develop products that truly serve the community and applications that fully utilize the radiometric potential of images, it is of great importance to detect requirements of various interest groups and to develop standardized, transparent processes. Also examples of new-generation radiometric test flight campaigns are given. Expected benefit of accurate radiometric processing is more automatic and efficient imagery post-processing, better visual image quality and more accurate, automatic interpretation. Many developments are in operation in the field of radiometrically quantitative photogrammetry and the future prospects are promising
