3D Model Projection for Concealed Hazard Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver warning systems in vehicles rely on stylized two-dimensional presentations, which require drivers to associate abstract representations with real-world objects, leading to delayed reaction times in hazardous situations, especially when objects are concealed or not directly visible.
Innovation Solution
A visual driver information and warning system that uses a three-dimensional model projection of concealed objects and hazards, integrated with a head-up display, allowing immediate comprehension and orientation within the driver's real-world view, with features like signal hue, flashing, and navigation data overlays to direct attention to potential dangers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If stylized two-dimensional graphics are used for driver information display, then the display can be simple and easy to implement, but the driver requires additional time to associate the presentation with real-world objects
Solution Approach 1:
The patent transitions from two-dimensional stylized graphics to three-dimensional model projections. The control device generates three-dimensional models of detected objects and projects them onto the head-up display, preserving spatial relationships and providing depth perception. This dimensional enhancement allows drivers to immediately comprehend object positions and hazards without needing to associate abstract 2D representations with real-world objects, thereby reducing reaction time while maintaining implementation feasibility through software-based model generation and projection.
2Loss of time
If three-dimensional model projection is used for hazard presentation, then the driver can immediately comprehend the presentation without association effort, but the system complexity increases
Solution Approach 1:
The patent introduces a control device as an intermediary component that receives data from ambient information capture devices, generates three-dimensional models, and projects them onto the head-up display. This intermediary layer manages the complexity by centralizing the model generation and projection functions, while the existing sensor infrastructure and display system remain relatively unchanged. The control device acts as a mediator that translates raw sensor data into comprehensible three-dimensional visualizations without requiring fundamental changes to the overall system architecture.
3Loss of information
If three-dimensional models are projected onto head-up display, then realistic representation of concealed objects is achieved, but the information processing requirements increase
Solution Approach 1:
The patent implements partial three-dimensional modeling by generating models only for detected objects that are relevant to driver safety and positioned within the display field of view. The control device processes ambient information from sensors and selectively creates three-dimensional projections for objects of interest, such as pedestrians, vehicles, or obstacles detected by the ambient information capture devices. This selective approach provides sufficient three-dimensional information for hazard perception without processing all environmental data, thereby managing computational load and energy consumption while maintaining information completeness for safety-critical objects.
