Vision-Based Path Guidance to Achieve Dies-Free Roller Hemming Process

A guidance directrix approach to vision-based vehicle guidance systems

In a vision-based automatic agricultural vehicle guidance system for row-crop applications, finding guidance information from crop row structure is the key in achieving accurate control of the vehicle. This paper describes a robust procedure to obtain a guidance directrix. The procedure includes row segmentation by K-means clustering algorithm, row detection by a moment algorithm, and guidance ...

Vision Based Control Approach to High Speed Automatic Vehicle Guidance

Vision-based Vehicle Guidance Lane Detection

F rom automatic transmissions to cruise control to antilock braking systems, passenger vehicles have incorporated automated subsystems that make driving easier and safer. Moreover, a growing number of microprocessors on late-model automobiles now monitor and control engine operations to improve mileage and reduce emissions. Thus an eventual move to autonomous, self-guided vehicles might be view...

Guidance-based Path following for Wheeledmobile Robots

This paper addresses the problem of path following for wheeled mobile robots (WMRs) by utilizing a novel guidance-based approach. The guidance laws are developed at an ideal, dynamics-independent level, entailing generically valid laws not influenced by particular peculiarities relating to any given dynamics case. Hence, the resulting guidancebased framework is equally applicable to any planar ...

Stochastically Optimized Monocular Vision-Based Guidance Design

This paper designs a relative navigation and guidance system for unmanned aerial vehicles for monocular vision-based control applications. Since 2-D vision-based measurement is nonlinear with respect to the 3-D relative state, an extended Kalman filter (EKF) is applied in the navigation system design. It is well-known that the vision-based estimation performance highly depends on the relative m...
