Researchers have developed DefVINS, a novel visual-inertial odometry pipeline specifically designed for deformable environments. Unlike traditional methods that assume rigidity, DefVINS models the odometry state by separating a rigid, IMU-anchored component from a non-rigid scene warp represented by a deformation graph. The team also introduced VIMandala, the first benchmark dataset featuring real images and ground-truth camera poses for deformable visual-inertial odometry, alongside enhancements to the synthetic Drunkard's benchmark. Experiments on these benchmarks demonstrate DefVINS' superior performance compared to existing rigid visual-inertial and non-rigid visual odometry baselines. AI
