Improving the Registration Precision by Visual Horizon Silhouette Matching
نویسنده
چکیده
A system for enhancing the situational awareness in an outdoor scenario by Augmented Reality (AR) techniques can utilize visual clues for improving registration precision. If visible, terrain silhouettes provide unique features to be matched with digital elevation map (DEM) data. The best match of a visually extracted silhouette with the DEM silhouette provides camera/observer orientation (elevation and azimuth). We have developed such a registration system which runs on a PC (200 MHz) and is being ported to a wearable AR system.

Registration for Outdoor Augmented Reality Applications Using Computer Vision Techniques and Hybrid Sensors
Registration for outdoor systems for Augmented Reality (AR) cannot rely on the methods developed for indoor use (e.g., magnetic tracking, fiducial markers). Although GPS and the earth’s magnetic field can be used to obtain a rough estimate of position and orientation, the precision of this registration method is not high enough for satisfying AR overlay. Computer vision methods can help to impr...

License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...
