Comprising the following steps of: constructing an APL8 (Activated Protein Label 8) data set of eight types of common agricultural pest larvae, and constructing an APL8 (Activated Protein Label 8) data set of the eight types of common agricultural pest larvae; the method comprises the following steps of: constructing a YOLOv8-LQG detection model on the basis of a YOLOv8 model, in combination with a designed LHF (Learnable Hue Filter) module, adding a QDDL (Quadruple Downsampling Description Layer) and a GLCM (Global Local Context Module) which fuses global semantics and local textural features, and constructing the YOLOv8-LQG detection model on the basis of the YOLOv8 model; a YOLOv8-LQG model is trained; and the YOLOv8-LQG model is tested.

The application relates to the technical field of calibration, and discloses a single-station-based rotating shaft calibration method, which comprises the following steps: obtaining a local initial point cloud by rotating scanning a house to be measured by a three-dimensional scanner, and calculating the transformation relationship between the local initial point cloud and a rotating shaft coordinate system to obtain the relative initial external parameter of the three-dimensional scanner and the rotating shaft; extracting a plane feature of the local initial point cloud in the rotating shaft coordinate system to obtain a plane point cloud and an index associated with the plane point cloud, and processing the plane point cloud based on the relative initial external parameter and the index associated with the plane point cloud to obtain a global local point cloud in a global coordinate system; constructing a target optimization function by using the index associated with the plane point cloud and the global local point cloud in the global coordinate system, and iteratively optimizing the relative initial external parameter by using the target optimization function to obtain a relative external parameter. The method provided by the application not only ensures the accuracy of the relative external parameter, but also reduces the time cost and improves the house measurement efficiency.
