UAV-based 3D infrared imaging of terrestrial constructions

3D reconstruction based on infrared images can restore the 3D model with temperature information, which helps observe the appearance and structure of the target more comprehensively and has potential application in the fields that need temperature detection, such as environmental monitoring and risk detection. This paper studies the 3D reconstruction of the infrared scene based on a UAV platform. An infrared camera captures the images, and the incremental SFM algorithm is used for further 3D reconstruction. The experimental results show that the 3D point cloud from the infrared image is satisfactory, the 3D reconstruction of terrain such as roads, houses, and trees is successful, and the 3D heat distribution of the scene can be displayed.
