The invention relates to the field of data processing, in particular to a three-dimensional scene reconstruction method based on point cloud data feature extraction, and the method comprises the steps: determining the type of a target region according to the region complexity of the target region and the collection dynamic influence degree, and determining the actual region state according to the proportion of a first type region and the concentration degree of the first type region, determining a task construction mode according to the actual region state; under the first task construction condition, determining the representation state of the aggregation region according to the area trend degree and the area reference value of the aggregation region, and performing secondary judgment on the task construction mode according to the representation state of the aggregation region; determining a task distribution mode according to a comparison result of the resource margin richness and a preset resource margin richness, wherein the task distribution mode is task distribution based on the resource margin or task distribution based on the resource margin and a conflict influence value; according to the invention, the model construction data management efficiency is improved.

This invention discloses a β-γ-ray dose equivalence test method for the irradiation qualification of nuclear power cables. Using the polyolefin sheath material of nuclear power cables as the test object, standardized Type II dumbbell test pieces with multiple thickness gradients are prepared. Gradient dose irradiation is carried out using β-ray and γ-ray devices matched to the design reference accident parameters. Through closed-loop environmental control, precise detection of elongation at break, least squares linear fitting, quantitative thickness correction, and equivalence verification, the β-γ-ray dose equivalence conversion relationship is accurately obtained. This invention solves the technical problems of existing technologies, such as the difficulty in implementing β-ray irradiation tests, the lack of a standard β-γ equivalence relationship, the significant influence of environmental / thickness interference on test data, and the lack of verification steps. It adds technical features such as closed-loop environmental control, thickness correction models, equivalence verification, and intelligent data processing, resulting in accurate and reliable equivalence ratios. It is applicable to the irradiation qualification of third-generation nuclear power cables, significantly improving test accuracy and licensing prospects.
