Method, device and equipment for generating traffic sign board image based on characters

The embodiment of the invention is suitable for the technical field of automatic driving, and provides a method, device and equipment for generating a traffic sign board image based on characters, and the method comprises the steps: determining a training set for model training, each group of training data comprises an original traffic sign board image and an original character binary image corresponding to the original traffic sign board image, and the original character binary image is generated according to characters in the original traffic sign board image; constructing a generative adversarial model, wherein the generative adversarial model comprises a generator, an image category classifier and an optical character recognizer; based on the training set, training the generative adversarial model to obtain a traffic sign generation model; and inputting the target character of the to-be-generated traffic sign board image into the traffic sign board generation model to generate a target traffic sign board
