The invention discloses a bill photo key information extraction system and method, and the system comprises a front-end module and a bill key information extraction module which is composed of a communication unit, a text detection unit, an identification unit, a key information extraction unit and a feedback unit, and the front-end module collects a picture and transmits the picture to the text detection unit through the communication unit. The text detection unit conducts text detection neural network reasoning and obtains the coordinate position of a text content block in a picture, the picture is correspondingly cut and then sent to the recognition unit through the communication unit, and the recognition unit recognizes text transcription content from the cut picture and sends the text transcription content to the key information extraction unit through the communication unit. The key information extraction unit conducts reasoning through a key information extraction network according to the coordinate po
