Software design of variable-spray control system based on VB and MATLAB

For the variable-spray control system based on machine vision, it is highly required to real-time image acquisition, processing as well as drive the actuator rapidly and stably. To reduce the developing cycle and programming difficulty, VB program language is used for its high executive efficiency to collect real-time information and control signals; meanwhile, MATLAB software is adopted for its excellent image processing function. Requirement of fast reaction for the control system is satisfied with COM component, it is introduced to combine VB and MATLAB to control variable-spray system, and it provides the foundation for future development and application.
