Method for Automatic Parcel Map Generation Based on Fusion of Image and Radio Frequency Communication Data

Abstract

The invention discloses an image and radio frequency communication data fused parcel map automatic generation method. The image and radio frequency communication data fused parcel map automatic generation method comprises the steps that a plurality of electrical boundary points are allocated to all households, and serial numbers of the electrical boundary points and land attribute information of all households are written in the electrical boundary points; the electrical boundary points are placed in order according to the land scopes of all households, and radio frequency communication signals are controlled to be transmitted; ortho-photo images are acquired through aerial photo of an unmanned aerial vehicle and treatment, and location coordinates of the electrical boundary points are extracted; the radio frequency communication signals transmitted by the electrical boundary points are received; according to the location coordinates of the electrical boundary points in the ortho-photoimages mapping to the radio frequency communication signals, an SURF algorithm is used for matching the placing order of the electrical boundary points and the land attribute information of all households, connecting is conducted according to the order of the serial numbers, and a panel is formed by boundary points wiring, and thus parcel maps of all households are acquired. According to the image and radio frequency communication data fused parcel map automatic generation method, the workload of household-entry boundary identifying carrying out of house site authentic right can be reduced, and accuracy and high efficiency of confirmation of land right are achieved.

Description

technical field [0001] The invention relates to a method for automatically generating parcel maps for fusion of image and radio frequency communication data, and belongs to the technical field of fusion of multi-source data. Background technique [0002] Land is the foundation of a country and is of great significance to the construction of the national economy and the harmonious development of society. With the steady advancement and development of social construction in our country, the problem of unclear property rights of rural homesteads needs to be resolved urgently. Through the confirmation and registration of rural homesteads, a series of disputes caused by ownership issues can be effectively avoided. How to fill in the area of ​​the homestead when registering the homestead is an important aspect of the ownership review. There is an urgent need for an accurate and efficient technical means to complete the collection and mapping of homestead information. [0003] At ...
