The labor cost is reduced, and the overall construction efficiency is improved.

The application provides a large model-oriented data storage and dynamic updating system and method, and belongs to the technical field of data updating and storage. The system comprises a data aggregation module, a storage module, a large model interaction module and a dynamic updating module. The original interaction data of a user is classified according to attributes, capabilities, environment and intention by a semantic recognition model, a single natural language user portrait document is generated by aggregation, and is stored in the form of a key-value pair. When a large model interacts, the system directly reads the document as complete context input, greatly improving the data acquisition efficiency. In addition, the system can update and maintain the document in real time according to interaction feedback. The application realizes the change from a "relational" to a "text" storage paradigm, significantly reduces the complexity of data query and processing and the Token consumption of large model interaction, guarantees the timeliness and accuracy of the user portrait, and thus improves the quality and efficiency of the personalized service of the large model.

The embodiments of the present disclosure realize the training of a model for directly detecting a parking space in a vehicle coordinate system based on multi-view images, and can effectively improve the accuracy of the parking space detection result.

The application relates to a three-dimensional laser engraving method, device, computer equipment and system. The method comprises the following steps: sequentially acquiring a two-dimensional gray scale image corresponding to each layer of an engraving object; acquiring engraving image data of each engraving point based on the two-dimensional gray scale image; sequentially controlling a displacement table to move to a starting position corresponding to each row of the engraving points and controlling the displacement table to move according to a specified program; and when the displacement table reaches a specified position, controlling a digital micromirror to perform parallel laser engraving operation based on the engraving image data of the corresponding engraving point. Through the application, the technical problems of low engraving efficiency and poor engraving quality in the related art are solved. The splicing step is removed by moving the displacement table, and the digital micromirror performs parallel laser engraving, thereby improving the efficiency and quality of laser engraving.
