The present application relates to the technical field of three-dimensional point cloud, and especially relates to a domain self-adaptive method and system for point cloud completion, equipment and storage medium, the method comprises the steps that a dual-domain shared Transformer point cloud encoder is constructed, a domain self-adaptive token is inserted in each self-attention layer of the encoder, the domain self-adaptive token automatically aggregates the geometric structure features shared by the source domain and the target domain in the self-attention process and suppresses domain-specific noise;Domain-invariant feature representation is extracted from the output position of the domain self-adaptive token to predict complete point cloud with a fractal point cloud decoder;The domain self-adaptive token is confusedly trained through a domain confusion loss, and is subjected to antagonistic domain alignment through a domain discriminator and a gradient reversal layer, realizing double domain self-adaptive constraints.The present application utilizes the structural characteristics of the learnable token in the self-attention mechanism, realizes more fine cross-domain feature self-adaption than global feature alignment, and significantly improves the generalization performance of point cloud completion under cross-sensor configuration.

The utility model relates to walnut processing equipment technical field discloses a kind of self-cleaning intelligent walnut green skin step-by-step pressing solid-liquid separation equipment, including rack, the rack right side outer wall is fixedly connected with driving motor, the rack top is fixedly connected with protective housing, the protective housing inside is rotatably connected with screw shaft by bearing, the screw shaft outer wall is fixedly connected with helical blade, the protective housing inside is fixedly connected with filter screen, the driving motor output end and the screw shaft outer wall between are connected by belt pulley, the protective housing top is provided with cleaning assembly, the protective housing outer wall is provided with extrusion component. In the utility model, adopt three-step-by-step pressing structure, through the design of screw shaft diameter increment and helical blade pitch decrease, gradually enhance pressing pressure, fully extrude walnut green skin material. After juice is efficiently separated by filter screen, juice extraction rate is significantly improved, and residue dryness is greatly reduced, to ensure that juice extraction is complete.
