A new measuring way different from the traditional deducting method for the angle of blade pitch was proposed based on high-speed camera and image processing. According to the experiment requirement

an experimental platform mainly based on the device of Micro Aerial Vehicle(MAV) and a new control system found on C8051F020 SCM were designed. In the platform

C8051F020 SCM was the MCU; the phase information of the propeller's main-shaft was tested with the micro position sensor and the PCA capture function of C8051F020 SCM. The four phase information of a propeller's main-shaft was gained by collecting the output signal of a position sensor; the motor speed was controlled by the output signal of PWM generated by C8051F020 SCM for controlling the motor speed up; a high-speed camera was touched off by the interrupt signal from the PCA capture in order to realize the synchronization between the speeding up of the motor and the taking pictures of the camera. This control system has compacted configuration and high reliability. Finally

using this system to control the MAV for simulating the forward flying

the electronic collector curve of MAV was obtained. It is proved that the proposed method and the experiment platform based this method can be used to measure the blade pitch and have met the design requirement completely.
