Detection method based on ridge energy correction for ribbon underground target in mountain land

Abstract

The invention discloses a detection, recognition and location method for a ribbon underground target in a mountain land by detecting the ridge position in the mountain land environment and carrying out energy correction. The method belongs to the cross fields of pattern recognition, remote sensing technology and terrain analysis. The ribbon underground target can generate unusual energy as the heat field of the ribbon underground target is different from that of a mountain body, the heat island effect of the ridge can also cause the unusual energy of the mountain body, but the unusual energy due to the heat island effect is essentially different from the unusual energy caused by the underground target in the aspect of mode, therefore, the invention aims to realize the effect of reducing the detection recognition false alarm rate of the ribbon underground target in the mountain land environment by eliminating the influence of the weak energy unusual mode of the heat body effect of the ridge to the ribbon underground target. The detection method based on ridge energy correction for the ribbon underground target in the mountain land comprises the steps that the terrain elevation information is obtained, the digital elevation information is subject to noise reduction preprocessing, the ridge line is detected, the energy at the ridge position is corrected, and the ribbon underground target is detected.

Description

technical field [0001] The invention belongs to the intersecting field of pattern recognition, remote sensing technology and terrain analysis, and specifically relates to a method for detecting banded underground targets in mountainous areas based on ridge energy correction. The method locates the ridge position through terrain analysis and corrects the ridge energy to improve The correct rate of recognition of underground targets in mountainous environments and the reduction of false alarm rates. Background technique [0002] There are a large number of belt targets in the mountain environment, such as underground rivers in the natural environment, artificial underground oil transportation pipelines, railway and road tunnels passing through the mountains, etc. Underground rivers are important water resources and must be avoided during construction in mountainous areas. Therefore, how to accurately detect and locate the location of underground rivers is of great significance...

Problems solved by technology

However, due to the heat island effect of the ridge, the energy field at the ridge position is more in line with the pulse mode, which interferes with the detection of banded underground targets in the mountain.
