Fire detection model training sample manufacturing method and device, equipment and medium

The invention provides a fire detection model training sample manufacturing method and device, equipment and a medium, and relates to the technical field of image processing. The method comprises the following steps: acquiring a plurality of initial background images under different brightnesses and different weather conditions; synthesizing a plurality of initial smoke images through fluid simulation software; traversing the plurality of initial background images and the plurality of initial smoke images, and randomly determining a target smoke image and a target background image corresponding to the target smoke image; inserting the target smoke image into the corresponding target background image to obtain a training sample for training a fire detection model, wherein the target smoke image is one or more of the plurality of initial smoke images, and the target background image is one or more of the plurality of initial background images. According to the method, the device, the equipment and the medium pr
