The invention relates to the technical field of sensors and precision measurement, and discloses an accurate matching method and system for data of an SMR chip of an encoder and a non-magnetic coded disc, and the method and system are characterized in that a special magnetic calibration pattern is integrated on a non-magnetic coded disc body, and the pattern is automatically driven to pass through the SMR sensing chip when the system is powered on, so that the non-magnetic coded disc is accurately matched with the SMR sensing chip. Bias, gain and phase error parameters are synchronously collected and calculated at a time, and the parameters are directly written into a programmable gain amplifier and a phase compensation register in the SMR sensing chip, so that front-end hardware-level real-time compensation carried out from a signal source is realized, and a closed-loop self-calibration system without external calibration is formed.

The invention discloses a binocular camera lens optical center change measuring method and device and electronic equipment, and the method comprises the steps: carrying a measured lens in a positioning device, and determining a first reference point based on at least three contact points formed by the positioning device on the outer diameter of the measured lens; establishing a first coordinate system by taking the first reference point as an original point and taking a direction pointing to the first mark point from the first reference point as a coordinate axis direction, and acquiring a first coordinate of the optical center of the measured lens in the first coordinate system; after the environment test is completed, the tested lens is carried in the positioning device again to determine a second reference point; establishing a second coordinate system by taking the second reference point as an original point and based on the same coordinate axis direction determined in the first coordinate system, and acquiring a second coordinate of the optical center of the measured lens in the second coordinate system; and determining the optical center variation according to the first coordinate and the second coordinate, and judging whether the optical center stability of the detected lens is qualified or not. According to the invention, the stability of binocular camera lens optical center change measurement and the reliability of measurement data are improved.
