Vision based embedded tiny spur gear inspection and measurement system

The machine vision based inspection and measurement system obtains more significant advantages, such as higher speed and accuracy. A vision based embedded tiny spur gear inspection and measurement system is proposed. The system, which is designed for measuring gear's addendum and dedendum diameter, and inspecting the tooth deformation. In this system, Field-Programmable Gate Array (FPGA) is used to extract the gear center and edge, and to conduct other image preprocessing. Digital Signal Processor (DSP) analyzes edge image to measure gear's diameter, and matches its contour to the designed diagram. The embedded vision system is real-time, small-size, non-contact, high-accuracy, high-speed, low-cost and low power consumption.
