Physical point layout method and device for multi-attribute electronic fence

The invention discloses a physical point layout method and device for a multi-attribute electronic fence. The method comprises the following steps: determining electronic fences of various obstacles in a target work area according to a digital orthophoto map; determining electronic fences of various risk sources of the high-risk area in the target work area according to the digital elevation model; combining the electronic fences of the various obstacles with the electronic fences of the various risk sources to determine a multi-attribute electronic fence; and performing offset processing on the physical points falling into the multi-attribute electronic fence according to the offset parameters of the standard observation system, wherein the physical points fall into an offset strip outside the multi-attribute electronic fence nearby. According to the invention, through multi-attribute identification of ground obstacles and terrain risks, various obstacle information and risk source information are extracted,
