AI Technical Summary

Technical Problem

In older browser kernel environments, navigation viewpoint synchronization correction during mirror flipping relies on high-frequency interception, leading to performance degradation. Especially in smooth and high-speed operations involving massive medical slices of hundreds of megabytes in size, existing solutions cannot effectively solve the problem of uncontrolled offset of the navigation red box.

Method used

By identifying the window tracking controller component within the navigation thumbnail view area, performing low-level rendering isolation processing, it is stripped from the nested structure of two-dimensional layers and pushed to the graphics processor process, stored in the three-dimensional tile video memory isolation storage space, and then performing coordinate realignment and correction based on mirror flip control instructions to achieve synchronous following with the high-definition main image view area.

Benefits of technology

Without upgrading the underlying kernel, it achieves active isolation and continuous dynamic following of the navigation red box, improving the smoothness of image reading and diagnostic reliability in medical device environments, and avoiding performance loss caused by high-frequency CPU back calculation.

Abstract

The invention discloses a synchronous correction method and device for a navigation visual area with mirror image flipping and a storage medium. The method comprises the following steps: identifying a window pursuit controller component in a navigation thumbnail visual area; executing a bottom layer rendering isolation processing operation on the window pursuit controller component; stripping and pushing the window pursuit controller component from the nested stacked structure of the original two-dimensional layer to a graphics processor process, and storing the window pursuit controller component into a three-dimensional block video memory isolated storage space; and performing coordinate re-alignment and correction on the window tracking controller component based on a spatial inverse matrix conversion rule corresponding to the mirror image overturning control instruction, and projecting the component to the navigation thumbnail visual area so as to finish synchronous following with the spatial position. According to the method, the navigation component is stripped from the nested structure through the bottom layer rendering isolation processing, and the coordinates are re-aligned based on the spatial inverse matrix in the independent three-dimensional video memory space, so that the radical correction of zero CPU dependence is realized, and the blockage of a main thread and the tearing of a picture are avoided.
