“…This study obtains aerial image data through this method and carries out post-processing (Ren et al, 2019;Weixing et al, 2015). Analytic aerial triangulation, also known as analytic aerial triangulation encryption, its calculation essence is to obtain the control point position through actual measurement within several air belts or in the LAN composed of several air belts and carry out adjustment calculation for all image pair encryption points and external orientation elements of all images (Amin et al, 2020;Abboud & Nofal, 2020;Hoque et al, 2017). At present, three methods are mainly used in analytic aerial triangulation, which are an independent model method, flight belt method, and beam method (Alfy, 2016;Bi, 2020;Xu, 2020).…”
