This paper describes the solution of the problem of detecting the area of a roadway in the image with the purpose of determining the lateral deviation of the vehicle as regard to the lane-line of the road, as well as proving the fact that the vehicle is on the road.
This paper describes the acquisition of a collection of representative image datasets for use in the development of autonomous planetary descent and landing navigation systems. These datasets were recently obtained using the VISILAB test-bench at ESA-ESTEC in The Netherlands, and represent realistic powered descent trajectories over a Lunar-type surface, but can also be relevant to a wide range of...
This paper describes a voice navigational system for the visually impaired which runs on the user's smart-phone as an application and requires no additional expensive or heavy hardware. This system requires just the live video stream from the user's phone camera and an internet connection, and hence can be used on the most basic of smart-phones. The system proposed here identifies obstacles in front...
Low cost MEMS sensors typically result in large position errors after very short periods of time unless they are frequently corrected by measurements from other systems. One form of measurements comes from the computer vision community where successive frames from a camera approximately looking at the ground can be used to compute the translation between frames. These measurements can be used to control...
We present a light-weight, cheap and low-power, wearable system for assisting the visually impaired in performing routine mobility tasks. Our system extends the range of the white cane by providing the user with vibro-tactile cues corresponding to the location of obstacles and a safe path for traversal through a cluttered environment. The presented approach keeps cognitive load to a minimum, and while...
In this paper, we present a complete framework for autonomous vehicle navigation using a single camera and natural landmarks. When navigating in an unknown environment for the first time, usual behavior consists of memorizing some key views along the performed path to use these references as checkpoints for future navigation missions. The navigation framework for the wheeled vehicles presented in...
