Abstract

The invention provides a multi-precision DEM (Digital Elevation Model) data difference smooth fusion method and system. The method comprises the steps of collecting topographic data of a scene where a transformer substation and a cable tunnel are located through an unmanned aerial vehicle, and obtaining topographic image data of the scene where the transformer substation and the cable tunnel are located within a calibrated topographic range; generating a first DEM model and a second DEM model according to the topographic image data of the scene where the transformer substation and the cable tunnel are located; and fusing the first DEM model and the second DEM model by using a difference method to obtain a fused digital elevation model. The system comprises modules corresponding to the steps of the method.

Description

technical field [0001] The invention discloses a multi-precision DEM data difference smoothing fusion method and system, belonging to the technical field of three-dimensional imaging. Background technique [0002] Data fusion generally refers to the combination, correlation and combination of data and information from multiple sensor information sources to obtain more accurate observation information to support the required decision-making and evaluation tasks; DEM fusion is to overcome the problem by mining complementary information between data. Deficiencies in data quality, improve data accuracy. However, when the existing DEM fusion technology builds a 3D model for the environment of the substation and cable tunnel scene, there are problems of low authenticity and low accuracy. Contents of the invention [0003] The present invention provides a multi-precision DEM data difference smooth fusion method and system to solve the problem of low authenticity and accuracy of ...
