The utility model relates to the technical field of maintenance equipment, in particular to a tool box for electric power maintenance, which solves the technical problem in the prior art that various tools with handle parts generally applicable to electric power maintenance cannot be effectively fixed and stored, and comprises a plurality of first limiting pieces arranged in an inner cover of an upper box body; each first limiting piece is provided with a limiting notch, each limiting notch is provided with a virtual axis, and the multiple first limiting pieces are arranged in rows or columns, so that the virtual axes are parallel to the width edge of the upper box body or perpendicular to the width edge of the upper box body; the second limiting assembly is arranged in the in-box space of the lower box body; each second limiting assembly comprises a limiting clamping piece and a sliding rail groove. Each set of sliding rails is in rail connection with at least two sets of limiting clamping pieces, and the limiting clamping pieces are provided with limiting spaces. According to the technical scheme, the function of a tool box similar to an inner mold box can be provided, the matched tool styles are more diversified, and the tool box is portable to carry.

The application discloses a kind of based on U-Net model's complex building classification extraction method, including with steps:Step1.Getting unmanned aerial vehicle image data;Step2.Make building classification dataset.Step3.Using classification building dataset respectively trains U-Net model, obtains building extraction model;Step4.Enhance dataset;Step5.Using enhanced dataset, U-Net model is fine-tuned training, obtains fine-tuned building extraction model;Step6.Model test: the building image of prediction dataset is input to step Step5 obtains fine-tuned building extraction model, and classification is identified to building.The application can be under the condition that building dataset is limited, to complex building type is effectively identified extraction, the building contour after segmentation is clear, building is complete, can exist in the form of single house, effectively improve the extraction accuracy of complex building.
