This invention provides a method and
system for hierarchical querying and rendering of
overlay point clouds in browsers, applied in the field of
data processing technology. For browser-side
overlay point cloud scenarios, it first collects
raw data such as point coordinates, colors, and frame sequences. Relying on a
parsing engine and
frame synchronization adapter, it completes data
parsing, deviation detection, and
standardization processing, and generates a fused dataset by combining interactive events. Then, it performs data layering according to three
layers: global, partitioned, and fine-grained, builds ternary association nodes, and constructs a topological association graph using a spatial indexing
algorithm. Subsequently, it extracts core features to generate embedding vectors, which are fed into the query rendering engine for iterative optimization, building a dedicated basic model. Finally, it conducts
verification and optimization based on interaction and frame loading
monitoring data, balancing query accuracy, rendering
frame rate, and compatibility through multi-index algorithms, ultimately achieving efficient hierarchical querying and rendering of
overlay point clouds in browsers.
