The application discloses a zero-shot visual language navigation method based on graph constraint optimization, and the method comprises the following steps: performing multi-stage decomposition, constructing a directed acyclic graph comprising path point nodes and object nodes, wherein each path point node corresponds to one straight displacement and one or less rotation movement, and determining a navigation sequence through topological sorting; converting semantic constraint relationships in the directed acyclic graph into mathematical constraint conditions based on a predefined constraint library, and the constraint conditions of each path point node are constructed based on the known coordinates of its parent node; solving the coordinates of the path point nodes by using a nonlinear optimization method, verifying whether the coordinates satisfy the drivable area constraint, and generating a navigation tree structure comprising multiple possible solutions; when the current path is not feasible, backtracking to an unexplored path with the deepest common parent node through a multi-solution path management mechanism of the navigation tree, and selecting an alternative path to continue navigation until the target position is reached.

The invention discloses a method and device for establishing a specific field modeling environment. The method comprises the following steps: constructing a three-layer abstract system for specific field modeling based on a meta-meta model; generating a domain meta-model containing entity class definition, relation class definition and enumeration class definition through an automatic instantiation rule, and configuring attributes, representation forms and constraint relations; packaging the meta-model and the constraint thereof into standardized framework data with a unique identifier; loading the frame data by a runtime analysis module, dynamically generating a visual domain model editor, and enabling a user to complete model construction conforming to constraints; triggering increment verification based on an operation-level event in a model construction process; when the meta-model is updated, executing difference comparison to identify affected model elements and giving repair suggestions; and the runtime expansion of the modeling capability is realized through a plug-in mechanism.

The application discloses a semantic association type coordinate conversion method for intelligent objects in an e-commerce scenario and belongs to the technical field of artificial intelligence, and comprises the following steps: S01: analyzing an input PSD design file and identifying intelligent objects and semantic association relationships therein; S02: performing contour analysis on irregular shape objects in the commodity main body; S03: combining the constraint relationship graph with the contour analysis and converting into a unified constraint optimization problem; S04: iteratively solving the unified constraint optimization problem through a constraint solving engine to obtain a coordinate conversion result that satisfies all constraint conditions and optimizes a visual quality objective function; and S05: performing multidimensional verification on the obtained coordinate conversion result, and outputting a final coordinate set and automatically rendering and generating an e-commerce design draft that is adapted to a specified canvas size after the verification is passed.
