Abstract

The invention relates to an optimization technology-based unmanned aerial vehicle positioning method capable of covering robot signals, provides the concept of agriculture and forestry robots and the demand market of the agriculture and forestry robots, and establishes a multi-constraint complex semi-definite programming model by using the optimization technology aiming at the defects of the agriculture and forestry robots in the aspects of signal sources and positioning functions. Through the structure of a multi-constraint complex semi-definite programming model, the model is decomposed into a multi-constraint simple semi-definite programming problem model and a sequence maximum meta problem model. The maximum element problem of the sequence is solved by using a cyclic strategy, and an efficient random algorithm for solving multi-constraint semi-scaling is designed. The method is used for solving the problem that in agricultural and forestry production, unmanned aerial vehicle positioning faces signal loss of covering robot signals and the like.

Description

technical field [0001] The invention belongs to the technical field of information processing, and relates to an unmanned aerial vehicle positioning method based on optimization technology that can cover agricultural and forestry robot signals. Background technique [0002] In the production activities of agriculture and forestry, it is necessary to use robots that can be operated automatically by no one, which are called agricultural and forestry robots. As far as the communication level is concerned, agricultural and forestry operations have a large area and a wide range, and it is not easy to establish a signal coverage network. In addition, the height of agricultural and forestry crops cannot be ignored compared with the height of farmland crops, which is one of the important reasons affecting signal coverage and signal communication. [0003] Robots within the scope of agriculture and forestry have a narrower field of view than farmland terrain, so agricultural and for...
