Tohoku University Technology:Program for automatic extraction and longitudinal visualization of topographic cross section: T20-504_S20-074
Easy viewing of curved topography! Useful program for management of river, road, waterway, coastline, etc.!
Point cloud data obtained from UAV photogrammetry is processed to create orthomosaic image, bird's eye view and 3D model, in order to understand the topography. However, in curvilinear topography such as river, road, waterway and coastline, it is difficult to grasp the whole picture of the curvilinear topography and its surrounding areas because these models are displayed in curvilinear form as they are. This technology provides a method and a program that can easily grasp curved topography visually. It has concretely the following features. ◆Automatic extraction of cross-sections from 3D point cloud ◆Easy viewing of the entire image by linear arrangement of curved topography ◆Able to compare topography changes over multiple time period ◆Obtain elevation of cross-sectional and longitudinal sections of the target topography ◆Display seasonal changes of the surrounding environment (vegetation, etc.)

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of June 1, 2025): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University
