Abstract: Based on the image processing technology, this paper designed a quadrotor aircraft teaching experiment system based on image of binarization processing. The system is relied on the attitude sensor, camera and master and auxiliary control embedded system chips. Firstly, according to the characteristics of quadrotor flight, a hardware system of quadrotor was built. Moreover, based on the image binarization processing and recognition results, a quadrotor aircraft flight control was designed, and the iron piece was thrown by the quadrotor and the iron piece was tested. A large number of test results in the system show the system has a success rate of 95% in the throwing iron test and 80% success in finding the iron piece. Through the design and application of the teaching experiment system, the students’ practical ability is improved
