Ceiling-Based Visual Positioning for an Indoor Mobile Robot With Monocular Vision
De Xu,Liwei Han,Min Tan,Youfu Li +3 more
TL;DR: A new visual positioning method is proposed based on the natural features on the ceiling that calculates the global orientation of the mobile robot from the main and secondary lines feature when the ceiling has parallels and recursively computed with the point features.

Accelerating embedded image processing for real time: a case study
TL;DR: A co-design methodology for processor-centric embedded systems with hardware acceleration using FPGAs is proposed to achieve real-time embedded solutions, using hardware acceleration, but achieving development time similar to that of software projects.
Journal ArticleDOI
Time-optimal velocity planning along predefined path for static formations of mobile robots
TL;DR: The developed trajectory planning algorithm is demonstrated on the formation of differential drive mobile robots and time-optimal velocity planning is achieved using so called bang-bang control where minimum and maximum accelerations of the formation are alternating.
