Vehicle Image Processing Device with Distortion Correction and Peripheral Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems for vehicles struggle to detect dangerous vehicles approaching from outside the display unit, as the switching to wide angle images is based on distance calculations within the displayed area, failing to account for vehicles outside this view.
Innovation Solution
An image processing device that includes an optical system forming images with low and high distortion regions, a processing unit for distortion correction, and a display control unit that displays low-distortion region data normally and switches to display data including detected vehicles from the high-distortion region when such vehicles are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a center portion image is displayed on the display unit during normal traveling, then the display unit shows clear and stable image data, but vehicles approaching from outside the display unit cannot be detected
Solution Approach 1:
The patent segments the image data into two distinct portions: a center portion image data (low-distortion region) and a wide angle image data (high-distortion region). The center portion maintains clarity for normal viewing, while the wide angle portion captures peripheral areas including regions outside the normal display unit, enabling detection of vehicles approaching from outside the conventional view.
Solution Approach 2:
The patent introduces a new dimension by displaying not only the center portion image but also overlaying or alternating with wide angle image data that captures peripheral regions. This dimensional expansion allows the system to detect vehicles in areas that would traditionally be invisible, effectively adding a peripheral detection dimension to the traditional central viewing dimension.
2Area of stationary object
If wide angle image is displayed to reduce oppression feeling, then the display unit shows broader field of view, but the feeling of oppression is not effectively reduced and peripheral vehicles remain undetected
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics for different regions. The center portion maintains high clarity and stability for primary viewing, while the peripheral wide angle regions provide broader coverage for safety detection. This localized differentiation ensures that each region serves its optimal function: the center for clear viewing and the periphery for comprehensive detection.
3Ease of operation
If distance to following vehicle is used to determine image switching, then the system responds to vehicles inside the display unit, but it fails to detect vehicles outside the display unit boundary
Solution Approach 1:
The patent performs preliminary action by continuously capturing and processing wide angle image data in advance, before vehicles approach within the conventional display unit boundary. The system pre-processes the high-distortion region images to identify vehicles in peripheral areas, enabling early detection and alert before the vehicles enter the central viewing zone, thus providing proactive safety warning.

Function Achieved in This Case
Enhances visibility and recognition of vehicles outside the normal display area by dynamically switching the display to include the detected vehicles, thereby improving safety by alerting the driver to potential hazards.
