Composite Image Transmission for Low-Latency 3D Model Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting and viewing large numbers of images, particularly 3-D models and medical image stacks, face challenges such as high latency, user-interface delays, and the need for extensive data transfer, which hinder efficient remote interactive viewing.
Innovation Solution
The method involves creating a combined image from a series of images, which is then transmitted to the user terminal, allowing for efficient compression and reduced data transfer. This combined image can be displayed in parts, enabling low-latency viewing and interaction without the need to download individual images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If individual images are transmitted separately, then image quality and accessibility are maintained, but data transfer time and network bandwidth consumption increase significantly
Solution Approach 1:
The patent combines multiple individual images into a single composite image structure where multiple images are arranged in a grid or mosaic format. This merging approach allows the entire image set to be transmitted as one data packet, dramatically reducing network round trips and transmission time while maintaining the ability to access individual images through the composite structure.
Solution Approach 2:
The composite image is segmented into multiple individual images arranged in a systematic grid pattern, allowing the receiving device to extract and display individual images on demand. This segmentation enables efficient transmission of the complete image set while maintaining random access capability to specific images without requiring transmission of the full original individual images separately.
2Ease of operation
If multiple individual images are displayed, then comprehensive viewing capability is provided, but user interface latency increases due to loading and displaying multiple images
Solution Approach 1:
The system pre-assembles multiple images into a composite image structure before transmission to the user's device. This preliminary action of combining images during the server-side processing eliminates the need for the user's device to load multiple images sequentially, thereby reducing display latency and improving user interface responsiveness.
3Adaptability or versatility
If 3-D models are transmitted to client devices, then interactive viewing is enabled, but intellectual property security is compromised due to potential reverse engineering
Solution Approach 1:
Instead of transmitting the original 3-D model data, the system creates and transmits a composite image copy that represents the 3-D model from multiple views. This copying approach allows users to view the 3-D model interactively through the composite image structure without receiving the underlying 3-D model data, thereby preventing reverse engineering and intellectual property theft.
Solution Approach 2:
The composite image acts as an intermediary representation between the original 3-D model and the user's viewing device. It provides the necessary visual information for interactive viewing while serving as a protective barrier that prevents direct access to the 3-D model data, thus securing intellectual property rights.

AI summary
A method of transmitting a series of 2-D images relating to a 3-D object or model between a server and a user terminal includes combining each of the 2-D images in the series of 2-D images into a single combined 2-D image, and transmitting the combined image to the user terminal.
