Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] Before identifying the orientation of the crab, it is necessary to distinguish the male and female crabs. The male and female crabs can be manually distinguished, or the male and female crabs can be automatically distinguished by smart devices, and the image of the crab's abdomen is obtained, and the image of the crab's abdomen and the image are established. Correspondence between male and female crabs.

[0057] The crab orientation is the relationship between the head of the crab and the horizontal direction, and the relationship between the head of the crab and the horizontal direction includes the angle between the head of the crab and the horizontal direction, and the positional relationship between the head of the crab and t...

Abstract

The invention discloses a crab orientation recognition method based on image segmentation, which belongs to the technical field of image processing. This method obtains the abdominal image of the crab, obtains the abdominal shell shape of the crab according to the abdominal image of the crab, obtains the minimum circumscribing rectangle of the abdominal shell shape, and identifies the orientation of the crab according to the minimum circumscribing rectangle and the male and female conditions of the crab; solves the current inability The problem of automatically and intelligently distinguishing the orientation of crabs; the effect of improving the intelligence degree of distinguishing the orientation of crabs has been achieved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of image processing, in particular to a crab orientation recognition method based on image segmentation. Background technique [0002] Crab is an aquatic product with high economic value and nutritional value. Before the crabs are sold, the crabs will be tied up for the sake of beauty and to prevent the claws from falling off when the crabs struggle. [0003] At present, most crabs are tied manually. During the binding process, skilled workers and unskilled workers have different binding speeds, different binding effects, and may be injured by crab claws. Contents of the invention [0004] In order to solve the problems in the prior art, an embodiment of the present invention provides a crab orientation recognition method based on image segmentation. The technical solution is as follows: [0005] In the first aspect, a method for identifying crab orientation based on image segm...
