Text positioning method and device for frame fine tuning, computer device and storage medium

The invention relates to a txt positioning method and device for frame fine tuning, a computer device and a storage medium. The method comprises the steps of obtaining a to-be-positioned identity cardimage; performing preliminary positioning of the determined text area on the to-be-positioned identity card image to obtain a candidate detection box; predicting fine tuning parameters by adopting afine tuning model; and adjusting the candidate detection box according to the fine tuning parameters to obtain text position information. The method comprises the following steps of: determining an outer frame for an obtained to-be-positioned identity card image; then determining candidate detection boxes of the text area, performing fine adjustment on the positions of the candidate detection boxes through a fine adjustment model to obtain an accurate text box, so text area positioning is conducted after priori information of identity card text area distribution is fully utilized, and the fineadjustment model is easy t
