Inter-Vehicle See-Through Warning for Hidden Risk Object Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current see-through systems in advanced driver assistance systems (ADAS) do not incorporate dangerous object images detected by the front vehicle into the image stitching for the rear vehicle, potentially causing driving hazards due to unseen risks.
Innovation Solution
An inter-vehicle communication see-through warning system that includes a front-vehicle terminal and a rear-vehicle terminal, where the front-vehicle terminal captures images, identifies risk objects, and transmits risk object information to the rear-vehicle terminal, which then marks these risk objects in the displayed image to warn of unseen risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the see-through system only stitches images from front and rear vehicles without incorporating risk object warnings, then the image stitching performance is improved, but driving safety deteriorates due to unseen hazards
Solution Approach 1:
The system segments the information display by separating the stitched image content from the risk object warning markers. The rear vehicle terminal displays both the stitched image from the front vehicle and independently marks risk objects detected by the front vehicle, allowing simultaneous achievement of image quality and safety without compromising either function
Solution Approach 2:
The patent introduces risk object warning markers as an intermediary element between the stitched image and the driver. These markers visually indicate hazardous objects detected by the front vehicle that may not be visible in the rear vehicle's direct field of view, mediating the information transfer to enhance safety while preserving the image stitching function
2Reliability
If the system marks all risk objects in the displayed image, then driving safety is improved, but information accuracy deteriorates due to marking objects already visible to the rear vehicle
Solution Approach 1:
The system applies local quality by selectively marking only those risk objects that are not already visible in the rear vehicle's field of view. The processor compares the front vehicle's detected risk objects with the rear vehicle's camera view and applies markers only to the difference set, ensuring accurate and relevant information without redundancy
Solution Approach 2:
The system performs partial action by marking only the necessary subset of risk objects - specifically those that are hidden from the rear vehicle's view but detected by the front vehicle. This avoids excessive marking of already-visible objects while still providing complete safety information for hidden hazards

AI summary
An inter-vehicle communication see-through warning method includes steps below. A first image (IMGI) is captured from a first field of view of a front vehicle and a second image (IMG2) is captured from a second field of view of a rear vehicle. One or more first objects are identified in the first image (IMG1). One or more second objects are identified in the second image (IMG2). In response to determining that the one or more first objects include one or more first risk objects, corresponding first risk object information is transmitted to the rear vehicle. One or more first target objects among the first risk objects that are not the second objects are marked in the displayed second image (IMG2) according to the first risk object information.
