            Abstract : 
Based on computer image processing, give a new method on helicopter rotors pyramid angle by CMOS -Camera. give a overall design of the system, compare image results with different camera´s location and analyze the system´s qualitative error. design a synchronized system by external synchronized pulse in order to catch the accuracy image and calculate the blade´s height differences by filter and edge detecting technique, finally tested the system´s accuracy.
