The invention provides a method, a device, equipment and a medium for identifying a taxi ticket, and the method comprises the steps: detecting a taxi ticket picture at a correct angle through a text detection model, extracting a region of interest containing characters, and specifically, extracting deep information through a backbone network; feature information of different scales is obtained through the spatial pyramid layer; after the feature information of different scales is spliced, determining a finally reserved region of interest by the double-end network; obtaining deeper information of each region of interest through a text recognition model, and obtaining a prediction result of a styling font in each region of interest; performing character-level classification on the prediction result through a full connection layer to obtain character strings of each region of interest; and finally, according to the obtained character string of each region of interest, obtaining various types of information in th
