Research on the Boundary Extraction of Cadastral Maps Based on UAV Images
This paper studies the potential of cadastral mapping based on unmanned aerial vehicles,and uses the ENVI Feature Extraction(FX)module for data processing.It mainly describes this workflow,including image pre-processing,the automatic extraction of the visible boundary of UAV-based images and data post-processing.Re-search findings show that it is very important to filter the extracted boundary maps to improve the accuracy of re-sults,and the results of accuracy assessment show that the extraction of 80%of boundaries is correct.Based on the automatic extraction method,the proposed workflow can accelerate and facilitate the creation of cadastral maps,but the extracted visible boundaries must be validated by landowners and other beneficiaries.
