Research on the Measurement of Driving Shaft Angle of Automobile Air Conditioning Actuator Based on Image Processing Technology

Based on the OpenCV image processing technology and the special geometric structure of the object to be tested, the rotation angle of the transmission shaft of the automobile air conditioning actuator is measured by the secondary data processing of the calculated angle. Through the verification of 10 samples, the measurement error is less than% of the 0.19, which provides key technical support for the realization of automatic zero and rotation accuracy detection of the transmission shaft.
