> Title:                Robotic Grasping and Depth Perception: Learning 3D
> Models from a Single Image
> 
> 
> The ability to perceive the 3D shape of the environment is a basic ability
> for a robot. We present an algorithm to convert standard digital pictures
> into 3D models.
> 
> This is a challenging problem, since an image is formed by a projection of
> the 3D scene onto two dimensions, thus losing the depth information.
> We take a supervised learning approach to this problem, and use a Markov
> Random Field (MRF) to model the scene depth as a function of the image
> features. We show that, even on unstructured scenes of a large variety of
> environments, our algorithm is frequently able to recover accurate 3D
> models.
> 
> We then apply our methods to robotics applications: (a) obstacle avoidance
> for autonomously driving a small electric car, and (b) robot manipulation,
> where we develop vision-based learning algorithms for grasping novel
> objects. This enables our robot to perform tasks such as open new doors,
> clear up cluttered tables, and unload items from a dishwasher.
