Synchronous Multi-Camera 360° Video Recording for Racetrack Performance Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inexperienced drivers face challenges in understanding and improving their high-performance driving on racetracks due to the complexity of telemetry data analysis, which is often unclear and requires precise track data for effective driver assistance systems.
Innovation Solution
A system comprising multiple cameras mounted on a high-performance road vehicle to record 360° video streams synchronously during racetrack performance, with a control unit and processing unit to store and process the videos, generating an instant-by-instant aerial view and three-dimensional mapping of the racetrack, allowing drivers to visualize their performance without needing complex telemetry analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If telemetry data analysis is used to analyze driving performance, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent creates a visual copy of the driver's actual trajectory by recording video footage along the track and overlaying it with the driver's path. This visual representation serves as a simplified copy that is much easier to understand than raw telemetry data, allowing drivers to grasp their performance without complex analysis tools
Solution Approach 2:
The patent replaces the mechanical/technical system of telemetry data collection and analysis with a visual/video-based system. Instead of using sensors and complex data processing, the system uses video recording and visual overlay techniques to convey performance information in an intuitive manner
2Measurement precision
If telemetry data is used to provide driver assistance, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent uses visual differentiation through color-coded overlays to represent various performance parameters. The driver's trajectory, ideal trajectory, and different performance metrics are displayed in distinct colors, making it easy for drivers to quickly comprehend their performance without needing to interpret complex numerical data
Solution Approach 2:
The patent transforms one-dimensional telemetry data (speed, acceleration, position values) into a two-dimensional visual representation on video footage. By projecting performance data onto the visual field of the track, drivers can spatially understand their performance in the context of the actual driving environment rather than abstract numbers
3Measurement precision
If precise track data is required for driver assistance systems, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces video footage of the track as an intermediary medium between the driver and the performance data. Instead of directly presenting complex track position data, the system uses visual video footage that naturally provides spatial context, making the data interpretation straightforward without requiring additional processing complexity
