The invention discloses an angular velocity vector detection method for a three degree of freedom spherical rotor. The angular velocity vector detection method for a three degree of freedom spherical rotor includes the following steps: equally dividing the spherical surface of a spherical rotor into 8 color blocks according to three orthogonal interfaces which pass through the center of sphere of the spherical rotor, setting the 8 color blocks with different color, and encoding according to the colors of the 8 color blocks; setting a plurality of color sensors on the surface of the spherical rotor, wherein the execution optical axis of each color sensor directly faces the center of sphere of the spherical rotor; and acquiring output signals of the plurality of sensors, and according to the duty ratio of the output signals of the plurality of sensors, and the cycle of single sensor signal, obtaining an angular velocity vector of the spherical rotor. The angular velocity vector detection method for a three degree of freedom spherical rotor has the advantages that an apparatus for detection occupies smaller volume; the subsequent data processing becomes convenient; high rotating speed measurement can be realized, thus being convenient for system integration.
Description
technical field [0001] The invention relates to the detection field of a three-degree-of-freedom spherical rotor, in particular to a method for detecting an angular velocity vector of a three-degree-of-freedom spherical rotor. Background technique [0002] In related technologies, the detection methods for three-degree-of-freedom spherical rotors mainly include the following types: [0003] 1. The magnetic periodic distribution of spherical rotor material is detected by Hall sensor; [0004] 2. Half of the surface of the spherical rotor is coated with high-reflectivity materials and half with low-reflectivity materials. At the same time, the mass is distributed according to a certain law, so that the rotation axis is on the reflectivity interface, which is detected by photoelectric sensors; [0005] 3. The surface of the spherical rotor is coated with black and white codes, which are detected by photoelectric sensors; [0006] 4. The longitude and latitude lines on the sur...
