Problems solved by technology

However, due to the influence of various disturbances on the existing unmanned aerial vehicle remote sensing devices equipped with aerial photography cameras, the movement of geographic information surveying and mapping aerial photography pan-tilts is actually a complex multi-mode high-order random motion, which makes the unmanned aerial vehicle remote sensing devices fly The attitude is changeable, and it is impossible to ensure that the aerial photography camera is always shooting vertically downward, which leads to the decline or even degradation of the imaging quality of remote sensing aerial photography images, which greatly affects the accuracy of remote sensing results, making aerial photography less accurate and narrow in application fields; further, due to remote sensing The technology is mainly for large-scale geographic information data collection. Existing aerial photogrammetry and remote sensing devices mostly use high-altitude aircraft and light and small aircraft as platforms. However, high-altitude aircraft and light and small aircraft have high requirements for flight conditions, and it is difficult to realize small low-altitude, high-precision, and quick-response geographic information data collection in a small area; moreover, the image sensor, high-precision attitude sensor and other equipment in the remote sensing device of the unmanned aerial vehicle need to be assembled on site when used, making the geographic information data collection efficiency low At the same time, when collecting geographic information data, repeated on-site installation of equipment is not conducive to grasping favorable weather, especially in emergency response to disasters, which will lead to the inability to collect geographic information data in time, and due to the distance between the geographic information data acquisition equipment and the aircraft The disassembly and installation between the attitude sensor and the image sensor also need to be disassembled and assembled frequently, and the installation parameters of the attitude sensor and the image sensor will change every time they are disassembled. Therefore, after installing the attitude sensor and the image sensor, Installation parameter calibration is required, which leads to low efficiency of geographic information data collection, and reduces the accuracy of aerial photography, which ultimately leads to a decrease in use value
