Based on UAV low-altitude photogrammetry technology, field control measurement method, such as Agisoft PhotoScan and Pix4D Mapper software, can process and produce DEM and DOM. Practical research on the processes and key technologies of digital products is under process. The field checkpoint measurement for the accuracy of DOM digital products made by low-altitude digital photogrammetry technology creates a basis for the practical application and development of digital products. The main contents of this paper are as follows: (a) The basic principles and processes of digital products for drone remote sensing image production, such as control point layout and measurement methods. (b) Based on the UAV photography technology, the digital product DOM and the field measurement control point accuracy evaluation are generated. (c). The polynomial curve digital model method is used to solve the elevation correction value, and the quadratic polynomial fitting model of the elevation point of the internal digital product is established, and the precision analysis is carried out. <\/jats:p>","DOI":"10.1142\/s0218001420590296","type":"journal-article","created":{"date-parts":[[2019,9,18]],"date-time":"2019-09-18T08:40:17Z","timestamp":1568796017000},"page":"2059029","source":"Crossref","is-referenced-by-count":4,"title":["The Accuracy of Low-Altitude Photogrammetry of Drones"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8143-2312","authenticated-orcid":false,"given":"Nan","family":"Guo","sequence":"first","affiliation":[{"name":"Faculty of Geomatics, Lanzhou Jiaotong University, Gansu Lanzhou 730070, P.
