Controller Matching Event Information to Captured Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information displaying apparatuses struggle to accurately match and display event information, such as road guide and POI information, on captured images in real-time, especially at high speeds or with varying reception intensities, leading to incomplete or delayed information delivery.
Innovation Solution
An information displaying apparatus and method that utilizes a controller to detect specific points within captured images using depth maps and current locations, matching event information from map data to the images, and displaying the results on a display unit, with optional adjustments based on speed and reception intensity to ensure timely and accurate information presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If event information is matched and displayed on captured images in real-time, then information delivery timeliness is improved, but at high speeds the matching accuracy deteriorates leading to incomplete or delayed information delivery
Solution Approach 1:
The system performs preliminary actions by pre-processing map data and event information before real-time operation. The controller pre-loads map data, pre-identifies event locations (POI, road guide information), and pre-establishes matching algorithms so that when real-time image capture occurs, the matching can be performed rapidly without compromising accuracy even at high speeds.
Solution Approach 2:
The system dynamically adjusts its operation based on vehicle speed. When speed exceeds a predetermined threshold, the controller modifies the matching process by using pre-processed data and simplified algorithms to maintain real-time performance. The system transitions between different processing modes depending on speed conditions, ensuring both timeliness and accuracy are maintained under varying operational conditions.
2Loss of information
If comprehensive event information is displayed on captured images, then information completeness is improved, but device complexity increases due to multiple processing requirements
Solution Approach 1:
The controller is designed as a multi-functional device that simultaneously performs image capture processing, map data matching, event information retrieval, and display control. By consolidating these functions into a single controller, the system achieves comprehensive information display without proportionally increasing overall device complexity. The capture unit and display unit work together under unified control to provide multiple functions through coordinated operation.
Solution Approach 2:
The system segments the information processing into distinct modular components: image capture module, depth map generation module, event information matching module, and display module. Each module handles a specific aspect of the processing chain, allowing comprehensive information display while keeping individual component complexity manageable. The segmented architecture enables independent optimization of each module.
3Measurement precision
If depth maps are used to detect specific point locations in captured images, then location detection precision is improved, but use of energy increases due to additional processing
Solution Approach 1:
The system applies partial action by generating depth maps only for specific regions or when necessary, rather than processing the entire image at full depth precision continuously. The controller selectively activates depth map generation based on detection needs, vehicle speed, and energy availability, achieving sufficient location precision without the full energy cost of continuous comprehensive depth processing.
