In this paper, we try to develop a general framework of 3D shape reconstruction strategy with extremely rare point cloud extracted for fish ethology research. Particle filter is first taken to focus on fish trajectory tracking from monocular video sequence. The Speeded Up Robust Features (SURF) technique will be adopted to match the same tracking fish across the overlapping view fields with more stable...
Underwater 3D object reconstruction is one of the most essential and fundamental tasks in ocean investigations. In this paper, we try to capture the inherent geometrical variation of 3D objects at multiple visual angels with the underwater vehicles and develop a novel underwater 3D object reconstruction model for the continuous video stream. Image enhancement will be first taken into consideration...
We study the stability of three-dimensional (3D) haptic interaction in Model-mediated Teleoperation (MMT) systems. In MMT, a simple object model is employed on the master side to approximate the remote environment. The haptic feedback is rendered locally on the master side based on model parameters which are estimated on the slave side. The main advantage of the MMT approach is that the haptic control...
We propose a novel radial function-based deformation (RFBD) approach to enable real-time modeling and haptic rendering of deformable objects for point cloud-based Model-Mediated Teleoperation (pcbMMT). In the pcbMMT system, a time-of-flight camera is employed on the slave side to capture a 3D point cloud model of the remote environment. This environment model is transmitted to the master along with...
