Obstacle Avoidance Using Stereo Camera
In this paper we present a novel method for obstacle avoidance using the stereo camera. The conventional obstacle avoidance methods and their limitations are discussed. A new algorithm is developed for the real-time obstacle avoidance which responds faster to unexpected obstacles. In this approach the depth map is divided into optimized number of regions and the minimum depth at each section is...
متن کاملObstacle Avoidance Using Stereo Vision: A Survey
Stereoscopy is a technique used for recording and representing stereoscopic (3D) images. It can create an illusion of depth using two pictures taken at two or more slightly different positions. There are two possible way of taking stereoscopic pictures by using special two-lens stereo cameras or systems with two single-lens cameras joined together. Stereoscopic pictures allow us to calculate th...
متن کاملStereo Vision Library for Obstacle Avoidance Applications
With this report we want to propose a new stereo algorithm, which is especially conceived to be used for robot navigation applications. It is fast and very robust, and allows to suppress the need of empirically set threshold values. The stereo library is self adapting and is able to manage environment luminosity modifications. A texture quality filter is used to drop those image portions which ...
متن کاملStereo - Based Autonomous Navigation and Obstacle Avoidance ?
This paper presents a stereo vision-based autonomous navigation system using a GPS and a modified version of the VFH algorithm. In order to obtain a high-accuracy disparity map and meet the time constraints of the real time navigation system, this work proposes the use of a semi-global stereo method. By not suffering the same issues of the regularly used local stereo methods, the employed stere...
متن کاملObstacle avoidance for an autonomous vehicle using force field method
This paper presents a force field concept for guiding a vehicle at a high speed maneuver. This method is similar to potential field method. In this paper, motion constrains like vehicles velocity, distance to obstacle and tire conditions and such lane change conditions as zero slop condition and zero lateral acceleration are discussed. After that, possible equations as vehicles path ar...
