Abstract

The invention discloses a method for acquiring and processing three-dimensional image of marine fish, a device, equipment and a medium. The method comprises: acquiring a first two-dimensional image, asecond two dimensional image, a third two-dimensional image and a depth map of a target ocean region by an underwater imaging device, acquiring a parallax map according to the first two-dimensional image and the second two-dimensional image, correcting the depth map according to the third two-dimensional image, obtaining the corrected depth map, based on the parallax map and the corrected depth map, the depth information of each fish being corrected, the corrected depth information of each fish being determined, and the target image including the three-dimensional information of each fish being obtained. According to the target image, the attributes of each fish are determined by depth learning method, which reduces the cost of acquiring the fish swarm distribution information and improves the accuracy of acquiring the fish swarm distribution information.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular to a method, device, equipment and medium for acquiring and processing three-dimensional images of marine fish. Background technique [0002] The evaluation of marine ecological quality is of great significance to the research of marine biology, environmental protection and fishery development. Obtaining fish distribution information is an important parameter for evaluating marine ecological quality. [0003] At present, it is mainly through manual fishing at fixed points to obtain fish distribution information. [0004] However, the artificial fishing method wastes a lot of manpower and material resources, and the fish's tendency to avoid fishing equipment makes it difficult to represent the overall sea area distribution based on the fish distribution information obtained from fishing. Therefore, the cost of obtaining fish school distribution information ...
