Vehicle Camera Composite Display With Aligned Orientation Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive recorders display multiple vehicle-mounted camera images side by side, making it difficult for users to intuitively grasp the directional relationship between the captured images and the host vehicle.
Innovation Solution
A display control device that combines captured images from multiple vehicle-mounted cameras into a composite image with a vehicle icon indicating the host vehicle, allowing users to easily identify the positional relationship by aligning the imaging direction and orientation of the vehicle icon, and selectively displays images based on user selection and tracking information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple captured images are displayed side by side, then all camera views are visible, but it becomes difficult to intuitively grasp the directional relationship with the host vehicle
Solution Approach 1:
The patent combines multiple captured images from different vehicle-mounted cameras into a single composite image that displays all views simultaneously. This composite image integrates the front, rear, left, and right camera views into one unified display, allowing users to see all directional information in one location rather than switching between multiple separate displays.
Solution Approach 2:
The patent introduces a vehicle icon as an intermediary element in the composite image. This icon represents the host vehicle's position and orientation, serving as a reference point that helps users understand the directional relationship between the captured images and the vehicle. The vehicle icon acts as a mediator that connects the abstract image data to the user's spatial understanding of the vehicle's orientation.
2Reliability
If all captured images are displayed simultaneously, then complete surveillance coverage is achieved, but display complexity and user confusion increase
Solution Approach 1:
The composite image is divided into distinct regions corresponding to each camera's field of view. Each captured image is placed in a specific segment of the composite image (front, rear, left, right), creating a structured layout that maintains complete surveillance coverage while organizing the display into manageable, easily distinguishable sections.
Solution Approach 2:
The vehicle icon serves as a central mediator that organizes the surrounding captured images. By positioning the vehicle icon at the center and arranging the four camera views around it in their respective directional positions, the display achieves a natural, intuitive layout that reduces complexity while maintaining complete surveillance coverage.
3Ease of operation
If captured images are displayed without spatial context, then display simplicity is maintained, but user understanding of image orientation is lost
Solution Approach 1:
The vehicle icon acts as a spatial reference intermediary that provides context for interpreting the captured images. By displaying the vehicle icon with its orientation aligned to the vehicle's actual direction, users can intuitively understand which way each camera is facing and how the images relate to the vehicle's position and movement.
Solution Approach 2:
The patent applies color coding to different regions of the composite image to indicate the direction each camera is facing. For example, the front camera view may be positioned at the top, rear at the bottom, left on the left side, and right on the right side, with visual indicators or color cues that reinforce the directional information, making spatial context immediately recognizable.
Data Source
AI summary
The display control device displays captured images around a host vehicle captured by a plurality of vehicle-mounted cameras on a display unit. The display control device includes an image combining unit configured to combine the captured images of the plurality of vehicle-mounted cameras to generate a combined image, and an icon combining unit configured to generate a composite image by combining a vehicle icon with the combined image. The icon combining unit generates the composite image so that the imaging direction of the vehicle-mounted cameras and the orientation of the vehicle icon in the combined image are aligned when viewed from the host vehicle.
