Robot and camera mounting device based on Beidou +3d high-precision navigation

The invention discloses a robot based on Beidou + 3d high-precision navigation and a camera mounting device, and relates to the technical field of robot development. The multi-state navigation system comprises a three-dimensional visual linkage navigation unit, a position calculation navigation unit, an intelligent analysis system, a preprocessing system, an auxiliary end derivation system, an accompanying imaging navigation unit, an intelligent terminal, a data acquisition end, an intelligent processing end and a robot unit. The robot unit comprises a robot body and a lifting assembly installed at the upper end of the robot body. The mounting unit comprises a base assembly and an image acquisition assembly mounted in the base assembly; the problems that in the prior art, monocular distance measurement in vision is often adopted, inertial position calculation analysis data of single model navigation is used for navigation, errors often exist due to space complexity in Beidou navigation measurement, the naviga
