Key text information extraction method and device, electronic equipment and storage medium

The invention provides a key text information extraction method and device, electronic equipment and a storage medium, and relates to the technical field of text detection and recognition. The key text information extraction method comprises the steps of extracting a text thermodynamic diagram of a target text region in a to-be-recognized image; performing edge detection on the text thermodynamic diagram to obtain a text region coordinate; cutting out a first text region image located in the text region coordinates from the to-be-recognized image; performing image feature fusion on a second text region image located in the text region coordinates in the text thermodynamic diagram and the first text region image to obtain a third text region image; and performing text recognition on the third text area image through a text recognition model to obtain key text information in the third text area image. According to the key text information extraction method and device, the electronic equipment and the storage me
