Abstract : At present ,the measuring meter for cervical vertebra disease before and after treatment has not yet been developed. A new kind of three2dimension measuring meter for rotation swing angle of cervical vertebra ac2 cording to GHC23 geodetic magnetic field orientation sensor and single chip processor is desingn. This portable meter has high accuracy ,low power consumption and can realize prompt measurement , and is an ideal diagnostic meter for cervical vertebra disease.
Key words : rotation and swing angle of cervical vertebra ; three2dimension measuring meter ; geodetic magnetic field orientation sensor ; error correction
