Image Processing Device Enhancing Lane Marker Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices struggle to clearly display the positional relationship between a vehicle and lane markers, especially when the lane markers are missing or unclear, particularly at night.
Innovation Solution
An image processing device with an image acquiring unit, detection unit, and display processing unit that captures images from multiple cameras, detects lane markers, and superimposes a marker image on the display to enhance visibility, adjusting the marker's width and form based on the detected lane markers' clarity and the vehicle's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the estimated bird's-eye image is produced from the rear bird's-eye image, then the positional relationship between the vehicle and the white line can be displayed, but the white line becomes missing or unclear when the original lane marker is missing or unclear
Solution Approach 1:
The patent creates a marker image that is a simplified copy or representation of the detected lane marker. This marker image is then superimposed on the bird's-eye view image to ensure the white line is always visible, even when the original lane marker is missing or unclear in the captured image.
Solution Approach 2:
The patent introduces a marker image as an intermediary element between the detected lane marker and the final displayed image. This marker image serves as a mediator that guarantees the visibility of the white line by being deliberately drawn with sufficient clarity and contrast, independent of the quality of the original lane marker detection.
2Ease of operation
If the marker image is superimposed on the captured image, then the driver can easily view the lane marker, but the complexity of the display processing increases
Solution Approach 1:
The patent separates the lane marker detection and display functions into distinct processing steps. The detection unit identifies the lane marker, while the display processing unit separately creates and superimposes the marker image. This segmentation allows each component to be optimized independently, managing overall system complexity.
Solution Approach 2:
The patent performs preliminary detection of the lane marker before generating the final display image. By detecting the lane marker first and then creating the marker image based on this detection, the system prepares necessary information in advance, simplifying the final display processing step.

AI summary
An image processing device includes an image acquiring unit, a detection unit, and a display processing unit. The image acquiring unit is configured to acquire a captured image from an image capturing device configured to capture an image of the periphery of a vehicle. The detection unit is configured to detect a lane marker defining a traveling track of the vehicle from the captured image acquired by the image acquiring unit. The display processing unit is configured to display, on a display device, a superimposition image as the captured image on which a marker image for supporting visibility of the lane marker is superimposed such that the marker image is superimposed on the lane marker detected by the detection unit.
