[0002] In the field of crane technology, in order to reduce labor intensity, improve work efficiency and ensure worker safety; In the existing technology, mobile cranes are used to replace traditional tower assembly, which reduces the workload of pole transportation, assembly and dismantling. At the same time, mobile cranes have advanced safety control systems and load and position limit alarm systems, which effectively reduce the safety risks of operations such as bad weather and overload, reduce the frequency of high-altitude operations, and greatly improve the efficiency of tower assembly construction; However, in actual use, mobile cranes have high requirements for the road conditions at the tower site and the actual terrain of the operation site. Under the condition of limited line corridor resources, the site applicability of mobile cranes is limited; In view of the above situation, the current method of disassembly and assembly or overall assembly is adopted, and cranes of different tonnages are selected on site according to the tower parameters and terrain conditions. However, mobile cranes have high requirements on the road conditions for access to the tower and the actual terrain of the operation site. Under the condition of limited line corridor resources, the site applicability of mobile cranes is limited. Summary of the invention

[0003] The present invention provides a mobile crane tower assembly docking monitoring device based on machine vision technology, which can overcome certain defects of the prior art.
