Business data enhancement method and device, computer equipment and readable storage medium

The invention provides a business data enhancement method and device, computer equipment and a readable storage medium, and relates to the technical field of data enhancement. According to the application, after the background image set and the target instance set corresponding to the business data set are obtained, the instance adding times of each background image in the background image set can be determined, and for each background image, a target object category is randomly selected from the target instance set; and randomly selecting a target instance object at a target image subset corresponding to the target object category, pasting and covering the image content of the target instance object in the target image subset to a target adding position in the background image, and repeating the steps. And a pseudo service image in the pseudo service data set is obtained until the number of the added instance objects of the background image is consistent with the instance adding times, so that the finally ou
