New visual odometry method estimates motion directly, boosting efficiency

Researchers have developed SMF-VO, a new visual odometry framework that directly estimates camera velocity from sparse optical flow, bypassing traditional pose-centric methods. This 'motion-centric' approach is computationally efficient, achieving over 100 FPS on a Raspberry Pi 5 using only a CPU. The method utilizes a generalized 3D ray-based formulation for accurate motion field estimation with various camera models, including wide-field-of-view lenses, making it suitable for resource-constrained robotics and wearable devices.
