Real-Time Space Information Coding for Dynamic Image Overlay Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video effect virtual enhancement technologies cannot achieve real-time overlay rendering of camera space information, as they do not store space information data in real time, leading to manual post-processing and lack of unified perspective in continuous dynamic images.
Innovation Solution
A method for coding space information in continuous dynamic images by parsing and extracting camera physical parameters and depth information, constructing data packets, and encapsulating them with audio or image data for real-time storage and rendering, enabling real-time overlay rendering of three-dimensional graphics and virtual elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If space information data is not stored in real time during video shooting, then the processing system remains simple, but real-time overlay rendering cannot be achieved and manual post-processing is required
Solution Approach 1:
The patent applies preliminary action by extracting and encoding space information data (camera parameters, depth information) during the video shooting process itself, rather than performing these operations after video capture. This allows the data to be prepared in advance for real-time overlay rendering, resolving the contradiction between achieving real-time rendering and maintaining system simplicity.
Solution Approach 2:
The patent segments the video data stream by separating space information data (camera parameters, depth information) from the main video content. This segmentation allows independent processing and encoding of space information, enabling real-time overlay rendering without requiring complex reprocessing of the entire video stream.
2Measurement precision
If space information data is extracted and encoded for each frame, then real-time rendering is enabled, but data processing complexity increases
Solution Approach 1:
The patent extracts only the necessary space information data (camera parameters, depth information) from each video frame rather than processing the entire frame data. This selective extraction maintains measurement precision for rendering while significantly reducing data processing complexity by focusing only on relevant parameters.
Solution Approach 2:
The patent transforms complex spatial and depth information into standardized parameter formats (camera parameters, depth values) that are easier to process and store. This parameter transformation maintains the accuracy needed for precise rendering while simplifying subsequent processing operations.
3Productivity
If manual post-processing is used to add virtual graphics, then system requirements are lower, but rendering efficiency and unified perspective are compromised
Solution Approach 1:
The patent performs preliminary extraction and encoding of space information data during video capture, so that when virtual graphics need to be added, the necessary camera parameters and depth information are already prepared. This eliminates the need for time-consuming post-processing analysis and enables efficient real-time rendering.
