According to the mathematical model, photogrammetry encryption can be divided into three methods.

According to the mathematical model, photogrammetry encryption can be divided into three methods: aerial tape method, independent model method and beam method. According to the query data, generally speaking, its work flow mainly includes seven main links: data preparation, automatic selection and measurement of indoor encryption points, interpretation and measurement of field control points, adjustment of photogrammetry area network, edge connection of encryption belt, quality inspection, and arrangement and submission of results. Photogrammetry encryption is one of the key processes in aerial photogrammetry. With the wide application of umbrella digital photogrammetry technology, the main encryption method used at present is the adjustment of regional network by beam method.
