Design and Implementation of Bicycle Testing Platform with Automatic Image Processing

In recent years, the sport consciousness and environmental consciousness are increased so that cycling has become very popular around the world. The demand of people increases of performance of the bike and one of these is the electronic shifting system. This paper designs and implements a test system that can achieve synchronizing control data measurement, flywheel gear recognition and ramp simulation of the bike test platform. That can test the emulate the different road environment, such as upward slope or downhill, etc. An automatic image process is developed to test the electrical shifter. The quality of motors, shifting position, pedal pressure and the shifting time can be measured automatically by using a high-speed camera.
