The invention provides a business balanced promotion method and device, a medium and a product. The business balanced promotion method comprises the steps of obtaining a historical exposure level corresponding to a target object in response to a promotion request for the target object; acquiring basic data corresponding to the target object; calculating the current exposure level of the target object by using the basic data and the recall model; and adjusting the exposure level of the target object according to the size relationship between the historical exposure level and the current exposure level, and carrying out balanced popularization on the adjusted target object. The exposure level of the target object is dynamically adjusted in real time, under-exposure or over-exposure of the target object is avoided on the premise that the exposure requirement of the target object is guaranteed, and balanced popularization of all objects including the target object in the total service is achieved.

This invention discloses a low-light enhancement method from the perspective of a drone, relating to the field of image processing and enhancement technology. It involves acquiring a sequence of consecutive low-light image frames of a target during drone flight, performing preprocessing operations including denoising and normalization to form a low-light image set, and using an image recognition algorithm to estimate motion between adjacent frames. This invention improves image clarity and visibility in low-light environments through dynamic range compression and detail enhancement processing. The dynamic range compression algorithm balances brightness differences in the images, avoiding local overexposure or underexposure, ensuring good visual effects under different lighting conditions. Detail enhancement processing, through multi-scale gradient fusion and adaptive sharpening, highlights texture and edge information in the image, improving detail clarity in low light. This allows the drone to more clearly identify targets when performing tasks at night or in low-light environments, improving the efficiency and accuracy of task execution.
