AI Technical Summary
Traditional two-dimensional vision methods are unable to accurately capture the three-dimensional geometric details of fish, making it difficult to accurately distinguish between sea-caught and farmed large yellow croaker, thus limiting technological breakthroughs in market supervision and wildlife resource protection.
A multimodal fish phenotypic plasticity classification method integrating 2D keypoint detection and 3D structured light is proposed. By constructing a multimodal classification model, high-precision structured light 3D reconstruction technology is used to obtain the geometric information of the fish surface, and key discriminant features with statistical significance are selected to construct a logistic regression discriminant formula suitable for rapid on-site identification.
The model has achieved accurate identification of the origin of large yellow croaker, with an accuracy rate of 97.14%, providing technical support for the intelligent identification and management of aquatic resources and improving the efficiency of market supervision and resource protection.
