This paper addresses the problem of recognizing and reconstructing real-world objects in cluttered environments to enable service robot to grasp the objects and manipulate them. A novel approach to combine disparity segmentation method with the closed-loop color region based segmentation is presented. Disparity map segmentation leads to definition of object region of interest (ROI) enabling autonomous...
Three dimensional scene reconstruction, sometimes referred as view synthesis, is a problem in the area of Stereo Vision, which is the most widely used method for gathering depth information from 2D scenes. Stereo vision finds many applications in automated systems such robotics, tracking object in 3D space and constructing a 3D spatial model of a scene. There are many human-machine control applications,...
Objects grasping and manipulation is a major task for housold and industrial robots. Sensing the objects with 3D laser scanners generating point clouds is a common approach for gathering object information. The abstraction from the raw pointclouds to high level representations is a necessity in the real world domain. This paper describes a method for the approximation of objects from scenes and an...
Model-based approaches in recognition and planning of robots work effectively, and these approaches can apply to model-less situation using autonomous model construction by an agent. There are problems about segmentation or shape fitting of various objects with different scales or shapes. In this paper, we construct a Head-mounted 3D multi sensor for 3D environment modeling and propose a method of...
We present work on vision based robotic grasping. The proposed method relies on extracting and representing the global contour of an object in a monocular image. A suitable grasp is then generated using a learning framework where prototypical grasping points are learned from several examples and then used on novel objects. For representation purposes, we apply the concept of shape context and for...
