  • Method for controlling hybrid scanning based on miniature reflecting device
    Patent number: 11852806
    Abstract: A method for controlling hybrid scanning based on a miniature reflecting device, which includes: loading parameters for determinant scanning and circular scanning, setting a scanning start point, and performing determinant scanning; performing low-pass filtering on received sampling data to filter an outlier in a sampling process, and performing singular value determining, to determine whether there is a valid connected domain within a scanning field of view; determining, as a target of interest, a valid connected domain with a maximum quantity of singular values, and obtaining a geometric center of the target of interest by calculating an average value of driving voltages corresponding to the singular values; performing circular scanning by using the geometric center as a scanning center, determining, in a process of scanning an outermost ring, whether singular values are centrosymmetrically distributed on the ring, to fine-tune the scanning center till the singular values are centrosymmetrically distributed
