The study introduces ‘ImMesh,’ a SLAM framework by The University of Hong Kong and the Southern University of Science and Technology for real-time, large-scale mesh reconstruction using a CPU. It efficiently combines localization and meshing using LiDAR, with exemplary runtime performance and accuracy, although scalability and loop correction are limitations.

Revolutionize Your Business with AI-Powered 3D Modeling
Improve Efficiency & Productivity: The rise of technologies like the metaverse, VR/AR, and video games has been transformative. Businesses are now leveraging 3D applications to enhance human lifestyle and increase productive efficiency.
What Are Triangle Meshes?
Triangle meshes are the backbone of these 3D applications. They represent the complex geometry of real-world environments and are essential for tasks such as sensor simulation, mapping, and collision detection.
The Challenge of Large-Scene Meshing
However, creating these meshes for large scenes is a challenge. Current methods are slow and can’t produce them at the speed required for real-time applications.
Introducing ImMesh: Real-Time Mesh Reconstruction
Efficient and Accurate: A recent breakthrough by researchers has led to the creation of ImMesh, an efficient system for real-time mesh reconstruction. It uses a LiDAR sensor to simultaneously reconstruct meshes and localize objects.
How Does ImMesh Work?
ImMesh innovatively converts the 3D meshing problem into a 2D one, streamlining the process. It’s proven to be fast and accurate, outperforming existing methods in both runtime performance and meshing accuracy.
Limitations and Future Improvements
While ImMesh is a major step forward, it’s not yet perfect. It struggles with large, flat surfaces and doesn’t have a mechanism to correct errors over time. Researchers are working on solutions for these issues.
