Abstract

The embodiment of the invention discloses a method and device for extracting bubbles from a dynamic ice image, equipment and a medium, and relates to the field of image processing. The method comprises the following steps: extracting bubbles from an original image through a preset neural network model to obtain a first intermediate image; segmenting the original image into n second segmented image blocks, and extracting bubbles from the n second segmented image blocks through a preset neural network model to obtain n second extracted image blocks; splicing the n second extraction image blocks into a second intermediate image according to the segmentation position arrangement sequence; and performing OR operation on the first intermediate image and the second intermediate image to obtain a binary image of the bubbles. By means of the method, the problems that when the bubbles are extracted from the dynamic ice image in the prior art, the textures in the dynamic ice image are recognized as the bubbles, bubble boundaries are not recognized clearly, a large number of small bubbles can be omitted, and holes exist in the extracted large bubbles can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of image processing, and more particularly, to a method, apparatus, device and medium for extracting air bubbles from dynamic ice images. Background technique [0002] When the aircraft passes through the clouds, the supercooled water droplets may undergo a phase change and cause icing after hitting the airframe. Icing will change the shape of the aircraft and the flow field around it, destroy the aerodynamic performance, reduce the maneuverability and stability, threaten the flight safety, and lead to air accidents in severe cases. The essence of aircraft icing is the dynamic icing process of supercooled water droplets. The supercooled water hits the low-temperature base and freezes, and the ice formed with non-uniformly distributed air bubbles is dynamic ice. The bubbles in the dynamic ice are the fundamental factors that determine the physical properties of the dynamic ice. By analyzing the c...
