Quadrotor Helicopter Flight Control Using Hough Transform and Depth Map from a Microsoft Kinect Sensor

John Stowers, Michael P. Hayes, Andrew Bainbridge-Smith
2011 IAPR International Workshop on Machine Vision Applications  
The Microsoft Kinect is a new, low cost game controller peripheral that calculates a depth map of the environment with good accuracy and high rate.  ...  In this paper we use the calibrated output of the depth sensor to obtain an accurate absolute depth map.  ...  Figure 6 shows the algorithm applied to a single image from a sequence captured during flight.  ...

Fast and accurate environment modeling using three-dimensional occupancy grids

Katrin Pirker, Matthias Ruther, Horst Bischof, Gerald Schweighofer
2011 2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops)  
In our experiments we compare our method with a state-of-the-art mapping procedure. Our results demonstrate that we achieve better results.  ...  Building a dense and accurate environment model out of range image data faces problems like sensor noise, extensive memory consumption or computation time.  ...  We captured a total of 181 depth images with a resolution of axis at 4 • .  ...

Tracking Large Variable Numbers of Objects in Clutter

M. Betke, D.E. Hirsh, A. Bagchi, N.I. Hristov, N.C. Makris, T.H. Kunz
2007 2007 IEEE Conference on Computer Vision and Pattern Recognition  
We propose statistical data association techniques for visual tracking of enormously large numbers of objects.  ...  We do not assume any prior knowledge about the numbers involved, and the objects may appear or disappear anywhere in the image frame and at any time in the sequence.  ...  We thank Lisa Premerlani, Shuang Tang, and Marianne Procopio for data analysis and implementation support, and Edward Lee, Jonathan Reichard, and Luise Allen for data collection.  ...

Biologically Inspired Visual Control of Flying Robots [article]

John Ross Stowers, University Of Canterbury
2013
All algorithms ran on the robot, in real-time or better, and hypotheses were always verified with flight experiments.  ...  The scope of this thesis is experimenting with biologically inspired visual control of flying robots through information processing, models of the environment, and flight behaviour.  ...  Images are captured at 640 × 480 pixels, at 15 times per second. Each image is taken with a 15 ms shutter time. The camera is fitted to look directly at the ground.  ...

Kompression, Modellierung und Echtzeit-Rendering von realistischen Material und Objekten

Nicolas Menzel, Multimedia Graphik, Guthe, Michael (Prof. Dr.)
2012
The realism of a scene basically depends on the quality of the geometry, the illumination and the materials that are used.  ...  These deviations may be subtle, but also substantial, allowing for a wide spectrum of material appearances.  ...  Instead, the full dynamic range of a scene can be obtained by taking multiple photographs, each one with a different exposure time.  ...
