Solution Overview

Problem

Current methods for tuning active safety systems in vehicles are time-consuming and expensive, requiring numerous real-world traffic scenarios, and alternative methods like augmented reality may not produce sufficiently realistic data sets for effective training.

Innovation Solution

A method to determine a trajectory for a camera on a moving vehicle by generating a sample set of trajectory indication samples, calculating reliability measures, and combining error measures to achieve a trajectory estimate within a predetermined error range, using sensors like cameras, RADAR, LIDAR, and GPS for data generation and simulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-world traffic scenarios are used for tuning active safety systems, then the training data is realistic, but the process becomes time-consuming and expensive

Engineering Contradiction:
Improverealism of training dataVSAvoidtuning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent creates virtual copies of real-world traffic scenarios through simulation. Instead of using actual recorded traffic data, the system generates synthetic training data by simulating vehicle environments, sensor behaviors, and traffic situations. This copying approach maintains the realism needed for effective training while eliminating the time and cost constraints of collecting and processing real-world data.

Inventive Principle:
Principle #26Copying

2Productivity

If augmented reality methods are used to generate training data, then the process is faster, but the data set lacks sufficient realism

Engineering Contradiction:
Improvedata generation speedVSAvoidrealism of data set
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces a sophisticated simulation environment as an intermediary between the simplicity of augmented reality methods and the realism of real-world data. This simulation layer acts as a mediator that incorporates detailed vehicle dynamics models, accurate sensor behavior models, and realistic environmental conditions, thereby generating training data that is both efficiently produced and sufficiently realistic for effective system tuning.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If multiple sensors are used to determine trajectory, then the accuracy improves, but the system complexity increases

Engineering Contradiction:
Improvetrajectory accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple sensor types (cameras, RADAR, LIDAR, GPS, inertial sensors) into a unified trajectory determination system. By merging these sensors and their data processing functions into an integrated system with centralized coordinate transformation and trajectory calculation, the patent achieves high measurement precision while managing system complexity through unified architecture rather than separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present invention relates to a method for inserting a fictive object (a0) into an image set (I) that has been generated by at least one camera (12) when attached to a moving vehicle (10). The method comprises: • determining an optical measure indicative of an optical condition that occurred during the generation of said image set (I); • inserting said fictive object (a0) into at least one image of said image set (I), wherein the visual appearance of said fictive object is modified such that it corresponds to said optical measure.
