A fine-tuning instrument reading method and system based on multi-center dynamic fusion and adaptive correction

Abstract

This invention discloses a pointer instrument reading method and system based on multi-center dynamic fusion and rotational adaptation, belonging to the field of computer measurement technology. Addressing the significant problems of reading accuracy interference and numerical fluctuations in complex industrial environments, this method utilizes the Canny-Zernike model to construct a rotating OBB frame sub-reading edge and a rotating bearing; it improves multi-line intersection points based on the RANSAC algorithm and constructs a multi-source circle center setting source to clearly eliminate outlier hub interference; it achieves multi-center dynamic fusion by setting confidence weights and a minimum amplitude model to obtain the optimal circle center coordinates; it uses a reference physical nominal value amplifier mapping model for adaptive zero-bias correction; and it combines Kalman pistons and fault self-checking mechanism piston jumps to achieve cross-model instrument readout without the need for equipment configuration, significantly improving the measurement accuracy and reliability of industrial inspections.
