Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying three-dimensional object models with high spatial information complexity requires significant memory and processing time, leading to poor real-time performance and reduced user experience.
Innovation Solution
A method and apparatus that involves receiving a pre-generated two-dimensional image set from a server, parsing and displaying a target image from this set based on a display instruction, rather than processing the three-dimensional model directly, thereby reducing memory and processing demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the three-dimensional object model is directly downloaded and processed on the client, then the display completeness and spatial information accuracy are improved, but the memory footprint and processing time increase significantly, resulting in poor real-time performance
Solution Approach 1:
The patent extracts only the necessary two-dimensional projection images from the complete three-dimensional object model data. Instead of transferring and processing the entire 3D model containing all spatial information, the system extracts and transmits only the specific 2D images needed for display at different viewpoints, significantly reducing data volume while maintaining display quality
Solution Approach 2:
The patent performs preliminary processing by pre-generating two-dimensional projection images from the three-dimensional object model on the server side before transmission to the client. This advance preparation eliminates the need for real-time 3D model processing on the client, reducing processing time and improving real-time display performance
2Reliability
If the three-dimensional object model is directly processed on the client, then the display quality and spatial information are maintained, but the memory consumption increases, leading to reduced real-time performance
Solution Approach 1:
The system extracts only the essential visual information in the form of two-dimensional projection images from the comprehensive three-dimensional model data. This extraction process retains sufficient display quality for visualizing the object from different viewpoints while dramatically reducing the memory resources required on the client side
Solution Approach 2:
The patent creates simplified two-dimensional image copies of the three-dimensional object model for display purposes. These 2D images serve as adequate representations that consume minimal memory while maintaining visual fidelity, replacing the need to store and process the full 3D model data on the client
3Loss of information
If the three-dimensional object model is directly processed in real-time on the client, then the spatial information completeness is maintained, but the processing complexity and time consumption increase, reducing user interaction experience
Solution Approach 1:
The system performs all complex spatial information processing and three-dimensional to two-dimensional projection conversions in advance on the server side. The pre-generated 2D images contain the essential spatial relationships and object features, enabling fast client-side display without real-time processing while preserving spatial information completeness for visualization
Solution Approach 2:
The patent extracts the critical spatial and visual information from the complete three-dimensional model and encodes it into two-dimensional projection images. This extraction captures sufficient spatial relationships and object characteristics for effective display while eliminating the computational burden of processing the full 3D model in real-time

AI summary
An image display method, an image processing method, a device and a medium are provided. The image display method includes: receiving a two-dimensional image set sent by a server, in which the two-dimensional image set is used for recording two-dimensional images of a three-dimensional object model at a plurality of different viewpoints; in response to a display instruction for the three-dimensional object model at a target viewpoint, parsing a two-dimensional target image corresponding to the target viewpoint from the two-dimensional image set; and displaying the two-dimensional target image.
