Large image multi-terminal cooperative processing method and application thereof

Abstract

The application provides a large image multi-terminal cooperative processing method and application thereof, and relates to the field of distributed system concurrent control. In order to solve the problems of high transmission delay and coarse concurrent lock granularity in the multi-terminal cooperation of large images, the global vector coordinates of the operation terminal are reduced to local relative coordinates relative to the underlying tile to generate local differential data packets; the service terminal performs directional pushing or asynchronous weak synchronization based on the matching results of the viewport state and the zoom level; the adaptive dynamic bounding box is generated based on the cursor position and is intersected and mapped with the space index tree, the micro area read-write lock is applied, and broadcasting is performed, so that the conflict micro area enters the read-only mode. The application is mainly used for efficient cooperative labeling of large-scale images, effectively reduces the network bandwidth consumption, and realizes fine-grained and non-susceptible concurrency.
