Active Reconstruction

Active reconstruction focuses on autonomously acquiring optimal sensor data for building high-fidelity 3D models, improving efficiency and quality compared to passive methods. Current research emphasizes using implicit neural representations, such as neural radiance fields and Gaussian splatting, coupled with planning algorithms that leverage uncertainty estimation to guide sensor placement. This approach is significantly impacting robotics and autonomous systems by enabling more efficient and accurate 3D scene understanding for tasks like navigation, object manipulation, and search and rescue.
