This invention provides a method,
system, device, and storage medium for generating advertising images in OTA (Online Travel Agency) scenarios. The method includes: receiving an
image generation request containing merchant attributes and advertising copy;
parsing the advertising copy using a large
language model, extracting core keywords, and breaking it down into at least one
image generation task based on merchant attributes; calling a finely tuned
image generation model to perform image generation operations based on the image generation tasks; performing triple
standardization constraint checks on the generated images, including size, content, and compliance; uploading qualified images to the platform
server and providing feedback on the results. This invention enables
fully automated generation from copy to advertising images, significantly improving image-
text matching accuracy and image generation efficiency, reducing labor costs and operational risks, and meeting the high-frequency, personalized batch advertising material production needs of OTA merchants.
