AI Technical Summary

Technical Problem

Existing technologies make it difficult to accurately determine saddle areas, leading to inaccurate identification of saddle areas during forest fire fighting and increasing the risk of casualties.

Method used

By acquiring a digital elevation model of a geographic region, using each initial grid as the central grid, N initial grids are determined as target grid regions. Initial terrain profile lines are determined along the four axes of symmetry of the target grid regions. The curve parameters of each profile line are calculated to determine whether a local geographic region is a saddle region and to determine the degree of saddleness.

Benefits of technology

Accurate identification of saddle areas improves the accuracy of saddle area determination, helps predict the difficulty of fire fighting, and improves the efficiency and safety of forest fire fighting.

Abstract

This disclosure proposes a method, apparatus, electronic device, and storage medium for determining saddle regions. The method includes: acquiring a digital elevation model of a geographic region, wherein the digital elevation model includes multiple initial grids; determining N*N initial grids as target grid regions, with each initial grid as a center grid, where N is an odd number greater than 1; determining four initial topographic profile lines along four axes of symmetry of the target grid regions; determining the curve parameters of each initial topographic profile line, wherein the curve parameters are used to describe the slope change of the initial topographic profile line when passing through the center grid; and determining whether the local geographic region corresponding to the initial grid is a saddle region based on the curve parameters of each initial topographic profile line. Thus, it is possible to accurately determine whether a geographic region is a saddle region, effectively improving the determination effect of saddle regions.
