Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to superimpose a suitable virtual space image on a real space image effectively, leading to suboptimal display images.
Innovation Solution
An image processing apparatus generates virtual space images corresponding to the imaging range of real space cameras, using CG data to superimpose these images on real space images, adjusting for camera positions and orientations, and displaying them on vehicle windows to create seamless and environment-responsive display images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a virtual space image is superimposed on a real space image, then the display image quality is improved, but the alignment accuracy between virtual and real images deteriorates
Solution Approach 1:
The patent introduces a coordinate transformation module as an intermediary that converts real-space camera coordinates to virtual-space coordinates. This mediator enables accurate alignment between real and virtual images by establishing a mathematical mapping relationship, resolving the alignment accuracy issue without requiring complex direct coordination between imaging systems
Solution Approach 2:
The patent creates a virtual copy of the real-space imaging section in the virtual environment. By installing a virtual imaging section that mirrors the real camera's position, direction, and angle of view, the system generates virtual images that naturally align with real images, simplifying the overall system architecture while maintaining high alignment accuracy
2Measurement precision
If the virtual imaging section is installed according to camera position and direction, then the image correspondence is improved, but the calculation complexity increases
Solution Approach 1:
The patent performs preliminary installation of the virtual imaging section by pre-defining its position, direction, and angle of view based on real camera parameters before actual image generation. This preliminary configuration establishes the correspondence relationship in advance, enabling accurate image alignment while reducing real-time calculation requirements
Solution Approach 2:
The patent transforms the problem by changing the parameter representation from complex spatial transformations to simplified camera parameter mappings. By using the real camera's position, direction, and angle of view as direct parameters for the virtual imaging section, the system achieves accurate correspondence with reduced computational complexity

AI summary
Provided is an image processing apparatus that includes an image generating section that generates, in reference to computer graphics (CG) data, a virtual space image corresponding to an imaging range of an imaging section on a real space. For example, a virtual imaging section is installed on a virtual space in a manner corresponding to the imaging section on the real space, and a CG object on the virtual space is imaged to generate a virtual space image. The image processing apparatus includes an image superimposing section that superimposes the virtual space image on a real space image obtained by the imaging section imaging an object on the real space, to obtain a display image.
