Video Object Segmentation-based Visual Servo Control and Object Depth Estimation on a Mobile Robot Platform
share
To be useful in everyday environments, robots must be able to identify and locate unstructured, real-world objects. In recent years, video object segmentation has made significant progress on densely separating such objects from background in real and challenging videos. This paper addresses the problem of identifying generic objects and locating them in 3D from a mobile robot platform equipped with an RGB camera. We achieve this by introducing a video object segmentation-based approach to visual servo control and active perception. We validate our approach in experiments using an HSR platform, which subsequently identifies, locates, and grasps objects from the YCB object dataset. We also develop a new Hadamard-Broyden update formulation, which enables HSR to automatically learn the relationship between actuators and visual features without any camera calibration. Using a variety of learned actuator-camera configurations, HSR also tracks people and other dynamic articulated objects.
