Image rapid registration method and system based on position template, and electronic equipment

The invention relates to a quick image registration method and system based on a position template and electronic equipment, and the method comprises the steps: extracting a template sub-image shot by each sub-lens, and taking the template sub-image of a central sub-lens as a reference image; calibrating a template sub-graph on the basis of the reference graph to obtain calibration data; according to the calibration data, performing image transformation on the template sub-image, and obtaining a position matrix during image transformation; shooting a target needing to be registered, and extracting a target sub-image corresponding to each sub-lens in the lens array; judging whether the target sub-image can find a corresponding position matrix or not, and if not, returning to the first step; if so, executing the next step; and extracting a position matrix corresponding to each template sub-graph, and performing assignment calculation on the newly-built non-assignment matrix to obtain a registration image corres
