Three-dimensional spatial representation method for semantic boundaries in digital outcrop models

|
By Zhicheng Dong, Hongjun Zhang, Yingwei Qu, Siwen Yang, Haitong Yang, Pan Tang
| Nature Verified
Abstract To enhance the automation and spatial accuracy of geological outcrop information extraction, this study proposes a three-dimensional (3D) modeling method oriented toward multi-class semantic boundary representation. High-resolution outcrop images at the centimeter scale were acquired using UAV-based oblique photogrammetry.
