Surround-view fisheye cameras are commonly used for near-field sensing in automated
driving. Four fisheye cameras on four sides of the vehicle are sufficient to cover 360° around …

This paper presents a new holistic vision-based mobile assistive navigation system to help
blind and visually impaired people with indoor independent travel. The system detects …

In fisheye images, rich distinct distortion patterns are regularly distributed in the image
plane. These distortion patterns are independent of the visual content and provide …

This paper presents a vision-based navigation strategy for a vertical take-off and landing
(VTOL) unmanned aerial vehicle (UAV) using a single embedded camera observing natural …

This paper presents a novel mobile wearable context-aware indoor maps and navigation
system with obstacle avoidance for the blind. The system includes an indoor map editor and …

With the growing use of head-mounted displays for virtual reality (VR), generating 3D
contents for these devices becomes an important topic in computer vision. For capturing full …

Many applications that process a point cloud data benefit from a reliable normal estimation
step. Given a point cloud presumably sampled from an unknown surface, the problem is to …

Omnidirectional cameras are becoming increasingly popular in computer vision and
robotics. Camera calibration is a step before performing any task involving metric scene …

This paper describes a novel projection model based on the so-called unified projection
model. The new model applies to catadioptric systems and wide-angle fish-eye cameras, it …

This paper describes a super-sensor that enables 360-degree environment perception for
automated vehicles in urban traffic scenarios. We use four fisheye cameras, four 360-degree …
