The detecting instrument for steel ball surface defect based on image detection technique, and is applied to detecting external bug area of steel ball in bearing. This paper puts forward the design consideration of detecting instrument and whole system structure. Aimed at the need of excellent real - time character and high control accuracy in detecting process, we designed the hardware circuit of detecting platform which adopted DSP as main processor, and realized the transplant of μC/OS-Ⅱon DSP. It solved problems about intricate structure and bad real- time character existed in traditional control module. Experimental results indicated that this control system satisfied excellently the requirement of high speed and real - time image detection.
