Abstract

This invention belongs to the field of image data processing technology, specifically relating to a connector position offset compensation method and system based on image processing. The method includes: obtaining a connector image and all its image blocks; determining the direction dominance index of each image block, determining the highlight pixels within the image block and the distance variance of their coordinates, determining the highlight aggregation coefficient, filtering direction requirement, and the optimized number of filtering directions for each image block; determining the edge features of the connector image, determining the geometric center coordinates and deflection angle of the connector in the image, determining the position offset and angular offset of the connector in the image, and performing fine-tuning compensation. This invention, through adaptive filtering direction numbering, eliminates computational redundancy in the phase consistency algorithm, eliminates interference from highlights on edge positioning, and ensures high accuracy and real-time performance of connector position offset compensation.
