Smoke detection method and device, electronic equipment and storage medium

The invention provides a smoke detection method and device, electronic equipment and a storage medium, and relates to the technical field of target detection, and the method comprises the steps: obtaining a to-be-detected smoke image frame; inputting the to-be-detected smoke image frame into a smoke detection model to obtain a smoke detection result corresponding to the to-be-detected smoke image frame; wherein the smoke detection model is obtained by training a target detection model based on a sample smoke image frame and a smoke detection label corresponding to the sample smoke image frame; the structure of each primary branch network in the target head detection module of the target detection model is obtained by optimizing the fitting complexity of each secondary branch network under each primary branch network in the original head detection module. According to the method, the smoke detection precision can be improved to the maximum extent while the model fitting load is reduced to the maximum extent. 本
