Surround View Image Transition Using 3D Interpolation Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surround view camera images for vehicles exhibit strong distortion, making direct display unsuitable, and abrupt transitions between different views can irritate drivers, necessitating a method for continuous and uniform image transitions.
Innovation Solution
A method involving a three-dimensional model space where a two-dimensional initial image is mapped onto two display images using different mapping functions, with an interpolating function transitioning between them by varying an interpolation parameter, allowing for smooth changes between display images.

Engineering Contradiction Analysis
1Speed
If a sharp cut is used to switch between display images with different views, then the switching speed is fast, but the driver may be confused by the rapid and unexpected transition
Solution Approach 1:
The patent applies dynamics by transitioning from a static sharp cut to a dynamic continuous transition. The display image transitions smoothly from a first view to a second view through continuous deformation of the three-dimensional model, creating a dynamic visual flow that adapts to the driver's perception needs while maintaining switching efficiency.
Solution Approach 2:
The patent introduces an intermediary transition process between two display views. Instead of direct switching, a continuous deformation process acts as an intermediary, gradually transforming the first view into the second view through intermediate states, thereby eliminating abrupt transitions and driver confusion.
2Ease of manufacture
If camera images with strong distortion are displayed directly, then the display process is simple, but the images are unsuitable for direct display and need transformation
Solution Approach 1:
The patent resolves the contradiction by introducing a three-dimensional model space as an intermediate dimension. Instead of directly displaying distorted two-dimensional camera images, the system maps images onto a three-dimensional vehicle model, performs transformations in this additional dimension, and then projects the transformed view back to two dimensions, ensuring both image suitability and processing efficiency.

AI summary
The invention relates to a method for determining a transfer between two display images. A two-dimensional starting image is mapped onto a first or second image by means of a first or second imaging function, and the first or second image is mapped onto a first display image. The starting image is mapped onto an interpolating image in the model space by means of an interpolating mapping function, wherein the interpolating image is determined by interpolating the first image and the second image in accordance with an interpolation parameter. The starting image mapped onto the interpolating image by means of the interpolating mapping function is mapped onto an interpolating display image, which transfers from the first display image to the second display image by varying the interpolation parameter.
