Sky segmentation method and device, computer equipment and storage medium

The invention discloses a sky segmentation method and device, computer equipment and a storage medium, and relates to the field of image processing. The method comprises the following steps: acquiring a first image segmentation probability of an image, wherein the first image segmentation probability is used for indicating a probability that a pixel point on the image belongs to the sky; based on the position mapping relation between the image and the sky hemisphere, the sky segmentation probability of the sky hemisphere is determined according to the first image segmentation probability of the target pixel point, the sky hemisphere is a hemisphere model established by taking the camera for collecting the image as the center, and the target pixel point is a pixel point with a corresponding space point on the sky hemisphere; the sky segmentation probability is used for indicating the probability that a space point on a sky hemisphere belongs to the sky; and based on the position mapping relation, determining a
