To improve the development of Unmanned Aerial Vehicle （UAV） oblique photogrammetry technology， this study detailed the development history， research status and hot research topics about this technology for engineering applications. Firstly， the development history， current research status and technical advantages of UAV oblique photogrammetry are introduced systematically. Secondly， the key operational procedures of UAV oblique phtogtammetry were analyzed in detail， covering camera calibration， image location， flight plan， image acquisition， surface 3D reconstruction and product generation. Thirdly， the applications of UAV oblique photogrammetry in engineering field were illustrated， such as the digital city construction， bridge inspection， landslide survey， topographic map. Finally， the study illustrated the the development directions and key issues for UAV oblique photogrammetry. The comprehensive analysis shows that the UAV oblique photogrammetry can be apply to geospatial data acquisition with features of large scale， multi-data and high efficiency， which has broad application prospects in engineering fields such as civil engineering， traffic engineering， surveying and mapping engineering.
