Form identification method and device and storage medium

The invention relates to a form recognition method and device and a storage medium. The method comprises the steps that a form recognition template is defined; a multi-task form frame line segmentation and classification network is adopted, form features are extracted through a multi-scale multi-level feature fusion learning sub-network, then a double-end multi-task sub-network obtains a textbox segmentation result through a form segmentation task according to the form features, and a form classification result is obtained through a form classification task; matching form template information according to a form classification result, and performing detection and check completion on the segmented textbox; detecting a text connected domain in the textbox, and adaptively positioning a text bounding box; based on a text classification and recognition mechanism, combining textbox region information in the template, and classifying and recognizing text contents according to text types; and verifying a handwritten
