Obstacle Detection and Avoidance System for Visually Impaired People
In this paper, we implemented a wearable system for visually impaired users which allows them to detect and avoid obstacles. This is based on ultrasound sensors which can acquire range data from objects in the environment by estimating the time-of-flight of the ultrasound signal. Using a hemispherical sensor array, we can detect obstacles and determine which directions should be avoided. Howeve...
متن کاملObstacle Avoidance System for Assisting Visually Impaired People
The aim of the paper is focused on the design of an obstacle avoidance system for assisting visually impaired people. A disparity map will be generated thanks to the use of a stereo camera carried by the user. Working on this map will allow to develop an algorithm for the obstacle detection in any kind of scenario. The design will be completed with the introduction of audio signal to assist the...
متن کاملWearable Obstacle Detection System for visually impaired People
This paper presents an obstacle detection system for visually impaired people. User can be alerted of closed obstacles in range while traveling in their environment. The system we propose detects the nearest obstacle via a stereoscopic sonar system and sends back vibro-tactile feedback to inform the user about its localization. The system aims at increasing the mobility of visually impaired peo...
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...
متن کاملVisually-guided obstacle avoidance in unstructured environments
This paper presents an autonomous vision-based obstacle avoidance system. The system consists of three independent vision modules for obstacle detection, each of which is computationally simple and uses a di erent criterion for detection purposes. These criteria are based on brightness gradients, RGB (Red, Green, Blue) color, and HSV (Hue, Saturation, Value) color, respectively. Selection of wh...
