Solution Overview

Problem

Display devices for motor vehicles face challenges in consistently representing image data due to vibration-related movements and independent movements of detection means, making it difficult to display a coherent image, especially when multiple detection devices are involved.

Innovation Solution

A method that captures image data sets, detects the position of detection means, searches for specific image features, corrects deviations using a conversion matrix recalculated based on movement direction and speed, and outputs a seamless image data set to the vehicle driver, utilizing a data processing unit with storage and output means.

1Reliability

If multiple detection means are used to capture image data, then the coverage and information quality are improved, but the image coherence and stability deteriorate due to independent vibrations and movements of each detection means

Engineering Contradiction:
Improveimage coherenceVSAvoidmultiple detection means
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple image data sets from different detection means into a single common image data set. The data processing unit combines the first and second image data sets into a unified representation that is displayed through the output means, eliminating the coherence problems of independent displays.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system uses detected position information of detection means and identified image features to calculate conversion matrices that correct deviations. This feedback loop continuously adjusts the image data to maintain coherence despite vibrations and movements.

Inventive Principle:
Principle #23Feedback

2Reliability

If the position of detection means is not corrected, then the system operation is simple, but the image representation stability deteriorates due to vibration-related movements

Engineering Contradiction:
Improveimage representation stabilityVSAvoidposition detection and correction system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of using mechanical stabilization systems to physically fix the detection means, the patent replaces the mechanical approach with computational methods. The system detects position deviations and uses conversion matrices to correct image data digitally, substituting mechanical stabilization with software-based correction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the parameters of image representation by calculating conversion matrices that account for position deviations, movement directions, and movement speeds. These parameter adjustments allow the system to compensate for vibrations without physical intervention.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If image data sets from multiple detection means are combined without conversion matrix recalculation, then the processing speed is faster, but the image coherence deteriorates

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary actions by detecting position information and identifying image features before combining the image data sets. Conversion matrices are calculated in advance based on detected parameters, allowing for coherent image merging without real-time computational delays during the actual combination process.

Inventive Principle:
Principle #10Preliminary action
