- Real-time vision system for mobile roboticsPublication . Silva, H. M.; Martins, A.; Soares Almeida, José Miguel; Oliveira Lima, Luís Carlos; Silva, E. P.; Patacho, A.This paper describes a real-time vision architecture for mobile robotics. It is integrated in the research program on mobile robotics pursued at the Autonomous Systems Lab ISEP-IPP. The implemented architecture is characterized by: low computational cost, low latency, low power, highly modularity, configurability, adaptability and scalability. A new method using run length encoding (RLE) colour transition allows real-time edge determination at low computational cost. A pipeline structure further reduces latency and allows a paralleled hardware implementation. A dedicated hardware vision sensor was developed in order to take advantage of the proposed architecture. The real-time characteristics and hardware partial implementation, coupled with low energy consumption address typical of autonomous systems applications.
