Vehicle Imaging Optics for Wide-Area High-Resolution Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems in vehicles require multiple high-resolution cameras to cover a wide range, which is inefficient and costly.
Innovation Solution
A movable apparatus with an optical system that includes a low resolution region near the optical axis and a high resolution region outside, installed to cover specific directions, combining stereoscopic projection lenses and image processing units to integrate images from multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple high-resolution cameras are used to cover a wide range, then imaging resolution is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies local quality by using an optical system where different regions of the imaging element have different resolution characteristics. The high-resolution region is strategically positioned to cover critical areas (rear, side-rear, and downward directions), while accepting lower resolution in the optical axis center region. This allows a single camera to provide high-resolution imaging in specific important directions without requiring multiple cameras.
2Area of stationary object
If multiple cameras are installed to cover all directions, then imaging coverage is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a single imaging device that performs multiple imaging functions simultaneously. The optical system enables one camera to capture images in multiple directions (rearward, side-rear, and downward) with high resolution in each direction, replacing what would traditionally require multiple specialized cameras. The imaging element's high-resolution region is utilized to serve multiple imaging purposes from a single installation position.
