Abstract:A Qt-based cross-platform real-time data visualization host software is designed for mobile robot visual servo systems by using C++ language. The software performs image processing algorithms and data analysis to realize the functions of drawing real-time trajectories of mobile robots and real-time parameter curves. First, the hardware component and its function of the mobile robot are introduced. Second, the development environment and design process of the host software are stated, and the detailed description of the operation flow of the image algorithm and real-time online drawing of waveforms are given. Finally, the data obtained by visual servo tracking control experiments are displayed in real-time to verify the effectiveness of the designed host software.
