Solution Overview
Problem
Existing three-dimensional image processing systems face issues with unnatural borders between visible light image data when generating a single piece of three-dimensional model data from multiple image capture points with different illumination environments, leading to undesirable display quality.
Innovation Solution
A three-dimensional image processing apparatus that obtains range image data and visible light image data from multiple devices, generates three-dimensional model data, sets a point of view, and renders display image data by selecting appropriate visible light image data based on the view point, ensuring seamless integration and improved display quality by eliminating visible borders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single piece of three-dimensional model data is generated from a plurality of pieces of visible light image data captured from different image capture points, then three-dimensional model data can be created, but unnatural borders between pieces of visible light image data appear in the display image depending on the set point of view
Solution Approach 1:
The patent divides the display image into multiple regions based on the set point of view, and selects different visible light image data for each region. This segmentation approach allows the system to choose the most appropriate image data for each specific region, avoiding the appearance of unnatural borders that would occur if a single image data source was used for the entire display image.
Solution Approach 2:
The patent applies different visible light image data to different regions of the display image based on the set point of view. Each region is assigned the image data that best matches its local requirements, ensuring that the displayed image maintains high quality and natural appearance throughout, rather than using a uniform image data source for all regions.
2Area of stationary object
If multiple pieces of visible light image data are used for rendering, then more comprehensive scene coverage is achieved, but borders between the image data become visible in the display image
Solution Approach 1:
The patent segments the display image into multiple regions and assigns different visible light image data to each region based on the set point of view. This segmentation allows the system to utilize multiple image data sources to achieve comprehensive scene coverage while maintaining display quality by carefully selecting which image data to use for each specific region.
Solution Approach 2:
The patent changes the selection of visible light image data based on the parameter of set point of view. By dynamically selecting image data according to the viewing angle and position, the system can maintain high display quality across different viewing conditions while still utilizing multiple image data sources for comprehensive coverage.
