Camera Feed Switching for Remote Vehicle Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous vehicle systems, operators remotely controlling vehicles lack real-time visual feedback of the vehicle's surroundings, especially when switching from automated driving to manual driving modes, which can lead to operational errors due to incomplete or unclear visual information.
Innovation Solution
A display control device that dynamically switches between internal and external camera feeds based on camera mounting status and image quality, ensuring the operator receives a clear and comprehensive visual representation of the vehicle's surroundings during remote manual driving, by displaying the mounted camera image if it meets quality criteria or switching to external camera images if internal images are subpar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system relies on mounted cameras for visual feedback, then the operator can obtain real-time images of the vehicle surroundings, but the image quality may be insufficient when cameras are not mounted or image quality is poor
Solution Approach 1:
The system merges multiple camera sources (mounted cameras on the vehicle and external cameras at remote locations) into a unified visual feedback system. The image display unit can switch between or combine images from different camera sources to ensure continuous and reliable visual information is provided to the operator, even when one source is unavailable or produces poor quality images.
Solution Approach 2:
The image display unit acts as an intermediary that receives images from multiple camera sources, evaluates their quality, and selects or combines appropriate images to present to the operator. This intermediary function ensures that the operator always receives reliable visual information by mediating between the raw camera inputs and the final displayed output.
2Device complexity
If the system uses only mounted cameras, then the setup is simpler, but the operator cannot obtain visual feedback when cameras are not mounted or image quality is poor
Solution Approach 1:
The image display unit is designed with multi-functionality to handle multiple camera sources (both mounted and external cameras). It can universally process images from any camera source, automatically selecting the appropriate source based on availability and image quality, thereby providing robust visual feedback without requiring the operator to manually configure different camera systems.
3Reliability
If the system switches to external cameras when mounted cameras are unavailable, then visual feedback reliability is improved, but the system complexity increases
Solution Approach 1:
The system implements dynamic switching between different camera sources based on real-time conditions such as camera availability and image quality. The image display unit continuously monitors the status of mounted and external cameras, automatically transitioning between sources to maintain reliable visual feedback, thereby adapting the system configuration dynamically rather than requiring fixed complex wiring for all possible scenarios.

AI summary
A display control device includes one of a mounting acquisition unit and an image quality acquisition unit, and a display controller, in which the display controller is configured to display a mounted camera image on a display screen in one of a case where a mounted camera is mounted in a moving object and a case where an image quality is equal to or more than a criterion, and display an external camera image on the display screen in one of a case where the mounted camera is not mounted in the moving object and a case where the image quality is less than the criterion.
