3D Obstacle Detection Using a Single Camera
This paper aims at detecting obstacles using a single camera in an unknown three dimensional world, for 3D motion of an unmanned air vehicle. Obstacle detection is a pre-requisite for collision-free motion of a UAV through 3D space. Most research towards vision based obstacle detection and avoidance has been done for 2D planar motion of ground robots and using active sensors like laser range fi...
متن کاملMulti-cue Visual Obstacle Detection for Mobile Robots
Autonomous navigation is one of the most essential capabilities of autonomous robots. In order to navigate autonomously, robots need to detect obstacles. While many approaches achieve good results tackling this problem with lidar sensor devices, vision based approaches are cheaper and richer solutions. This paper presents an algorithm for obstacle detection using a stereo camera pair that overc...

متن کاملDetection of Obstacle and Freespace in an Autonomous Wheelchair Using a Stereoscopic Camera System
Computer Vision has been a very new field developing rapidly in recent years. One of the main advantages in this development is that the “human vision” abilities such as electronically perceiving and understanding of images are provided to apply to autonomous vehicles or mobile robots. In this paper, detection of obstacle and freespace in an autonomous wheelchair using a stereoscopic camera sys...
متن کاملAdaptive Visual Obstacle Detection for Mobile Robots Using Monocular Camera and Ultrasonic Sensor
This paper presents a novel vision based obstacle detection algorithm that is adapted from a powerful background subtraction algorithm: ViBe (VIsual Background Extractor). We describe an adaptive obstacle detection method using monocular color vision and an ultrasonic distance sensor. Our approach assumes an obstacle free region in front of the robot in the initial frame. However, the method dy...
