A robot vision system is developed based on an intelligent image gathering card that contains an FPGA (Field Programmable Gate Array) and a DSP (Digital Signal Processor) as main calculators. Two real-time visual modules are developed through the cooperation of hardware logics on FPGA and software on DSP. First, with edge images extracted by the FPGA, a highly efficient algorithm is designed to extract...
Whether the mobile robot has the ability to explore an entire environment influences the integrality of map built by mobile robot in unknown environment. However, this demand becomes challenging when mobile robot experiences positioning error and sensor noises in practical environment. In this paper, a novel exploration approach called FRT is proposed to solve the problem. The moment invariants widely...
In this paper, the development of an intelligent image grabber and its application to a multi-scale focus pseudo omni-directional robot vision system is presented. The new developed intelligent image grabber is designed using DSP and FPGA technology, which can do both the task of image grabbing and the task of image processing. A pseudo omni-directional robot vision system, which can "see"...
