With the rapid development of information technology, two-dimensional basic geographic information data are difficult to meet the requirements of urban informatization construction in China, and a three-dimensional digital urban model becomes an important direction for urban geographic information system research. At present, for constructing a three-dimensional digital city model geometric modeling, an oblique photography technology is mainly adopted to solve the problems of non-universality of data between a vertical photography image and a satellite image and between measurement ground equipment and complex post data processing. Oblique photography is to carry a plurality of cameras on an aircraft and shoot images from different angles such as vertical and oblique angles, so as to obtain more complete and accurate information of ground objects. Compared with the traditional manual modeling, the three-dimensional model generated by the method has the advantages of shorter period, lower cost and higher precision. The three-dimensional modeling of oblique photography can quickly restore the real current situation, has the advantage of no conflict compared with the traditional vertical aerial photography, not only effectively makes up the defects of the traditional positive photography image, but also greatly improves the data acquisition efficiency of the rapid three-dimensional modeling technology. The multi-rotor oblique photography technology is a high and new technology developed in recent years in the field of international remote sensing and surveying and mapping. The method breaks through the limitation that the traditional aerial survey single camera can only shoot and obtain an orthoimage from a vertical angle, and acquires real images with spatial information by carrying a plurality of image sensors on the same flight platform and inclining a plurality of different angles so as to obtain more comprehensive ground object texture details and present a real visual world which accords with human vision for a user. The oblique photography true three-dimensional data can write and reflect the attributes of the appearance, the position, the height and the like of the ground object on the spot, the high immersion feeling brought by the three-dimensional data is enhanced, and the defect of low simulation degree of the traditional artificial modeling is overcome. Use present comparatively fiery unmanned aerial vehicle to carry on oblique photography camera simultaneously and carry out topography survey cooperation automatic modeling system can bring revolutionary efficiency promotion for the survey and drawing field. The unmanned aerial vehicle photography system has the characteristics of low altitude, convenience, flexibility, high image resolution and the like, is a more ideal and easily popularized oblique photography mode, but the existing tripod head is complex in general structure, large in size, heavy in weight and inconvenient to use.
