Character coordinate determination method and device

The invention provides a character coordinate determination method and device, and the method comprises the steps: extracting a text contour of a target text line in a text line image, and determining a textbox coordinate of the target text line in the text line image based on the text contour; determining position information corresponding to the initial characters in the target text line, performing vertical segmentation processing on the target text line, and determining a segmentation interval coordinate corresponding to the target text line according to a processing result; updating segmentation interval coordinates according to the position information, and determining target segmentation interval coordinates corresponding to the initial characters based on an updating result; and calculating character coordinates corresponding to the initial characters based on the textbox coordinates and the target segmentation interval coordinates. The character coordinates of the initial characters are accurately ca
