Vehicle Body Visibility Correction in Driver Assistance Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems struggle to clearly distinguish the vehicle body from its surroundings, particularly in varying lighting conditions, making it difficult for drivers to accurately estimate distances during parking, leading to potential safety issues.
Innovation Solution
A driver assistance apparatus equipped with a camera and controller that processes images to correct luminance and color deviations within the vehicle body region, enhancing contrast between the vehicle and its environment, thereby improving visibility and safety during parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera captures the vehicle body in the field of view, then the driver can see the vehicle's position, but the vehicle body blends with the surroundings making it difficult to distinguish
Solution Approach 1:
The system changes the color representation of the vehicle body region in the captured image by detecting the vehicle body's location and adjusting its luminance and color values. This makes the vehicle body stand out from the surrounding environment, allowing drivers to clearly distinguish the vehicle's position and estimate distances accurately during parking maneuvers.
Solution Approach 2:
The system applies local image processing by identifying the specific vehicle body region and applying correction only to that area while leaving the rest of the image unchanged. This localized approach enhances the vehicle body's visibility without distorting the overall scene, maintaining accurate spatial relationships while improving distinguishability.
2Adaptability or versatility
If the camera captures images in varying lighting conditions, then the system can operate in different environments, but the vehicle body and surroundings have similar luminance making them indistinguishable
Solution Approach 1:
The system dynamically changes the luminance parameter of the vehicle body region based on the detected lighting conditions. By adjusting the luminance value of the vehicle body portion in the image, the system maintains adequate contrast between the vehicle and surroundings across various lighting environments, ensuring consistent visibility and measurement precision.
3Reliability
If the driver assistance system processes images to enhance vehicle body visibility, then the vehicle can be distinguished from surroundings, but the processing complexity increases
Solution Approach 1:
The system segments the image by identifying and separating the vehicle body region from the surrounding environment. By detecting the vehicle body's position and boundaries, the system applies image processing corrections only to the relevant region, simplifying the overall processing complexity while effectively enhancing vehicle body visibility and distinction.

AI summary
A vehicle is disclosed that includes a display, a camera having a field of view including a part of the vehicle and configured to obtain an image outside the vehicle, and a controller configured to process the image. The controller is configured to identify a region representing the part of the vehicle in the image, correct at least one of luminance or color of the identified region, and display a corrected image including the corrected region on the display.
