Character extraction method and device, equipment and storage medium

The invention provides a character extraction method and device, equipment and a storage medium, and belongs to the technical field of data processing and big data. The method comprises the steps that in response to the start of a character extraction process, to-be-recognized image information, at least one piece of extraction task information, at least one textbox and textbox attributes corresponding to the textboxes are obtained, and the textbox attributes comprise to-be-extracted texts; generating an input tensor according to each textbox attribute and the to-be-recognized image information; inputting the input tensor into a data extraction model corresponding to the character extraction process to obtain an output tensor output by the data extraction model; determining a target element sequence corresponding to the target extraction task information in the output tensor according to the types of the elements in the output tensor and the target extraction task information; and according to a target elemen
