Abstract: Since the 21st century, with the rapid development of cloud computing, big data, internet of things, machine learning and other information technology fields, human beings have entered a new era of artificial intelligence. The subject of photogrammetry has also followed the tide of the new round of scientific and technological revolution and developed rapidly into the brand-new generalized photogrammetry and entered the era of integrated intelligent photogrammetry. Its carrier platform, instruments and data processing theories as well as application fields have also changed significantly. The multi-sensor and multi-level integrated stereo observation technologies from spaceborne, airborne and terrestrial platforms have been greatly developed. In this paper, the novel concept of generalized photogrammetry is first put forward, and its subject connotation, development characteristics and some key technologies and applications are discussed in details. Under the brand-new generalized photogrammetry framework, data acquisition presents the characteristics of multi-angle imaging, multi-modal collaboration, multi-time integration, multi-scale linkage, while data processing presents the trends of multi-feature coupling, multi-control constraints, multi architecture processing, and multi-disciplinary intersection. The all-round development and intelligent service of the general photogrammetry still need to make greater breakthroughs in the aspects of spaceborne, airborne and terrestrial multi perspective or multi-modal image processing, intelligent information extraction and monitoring, combined 3D modeling with point cloud and image, autonomous control of unmanned system, visual inspection of intelligent manufacturing system, etc. Finally, new theories and technologies from real-time or quasi real-time intelligent geometric processing of multi-source remote sensing datasets to information extraction and intelligent service need to be established, which will make a well foundation to meet the new eara of intelligent surveying and mapping.

Key words: generalized photogrammetry, integrated spaceborne, airborne and terrestrial observation, multi-sensor integration, multi-source remote sensing data, intelligent photogrammetry
