Multi-Camera Ski Jump Video Recording System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video recording systems for capturing ski jumps are inadequate as they often result in poor quality, non-uniform videos that are cumbersome to analyze, especially when trying to compare multiple jumps or distinguish between different athletes, as they require manual recording and lack standardized formats for analysis.
Innovation Solution
A video recording system utilizing multiple cameras positioned along different path sections of a ski jump, with an acquisition unit that switches between camera streams to create a seamless, high-quality video sequence, incorporating motion detection for optimal image capture and data overlay, allowing for automated and efficient recording and comparison of ski jumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single camera is used to capture the entire ski jump path, then the equipment complexity is reduced, but the video quality and coverage completeness deteriorate
Solution Approach 1:
The ski jump path is divided into multiple path sections, with each section captured by a dedicated camera. The acquisition unit switches between cameras to create a complete video sequence, resolving the contradiction by segmenting the recording task across multiple devices rather than attempting single-camera coverage.
2Manufacturing precision
If multiple cameras are used to cover different path sections, then the video recording quality improves, but the device complexity increases
Solution Approach 1:
Multiple camera feeds are merged into a single standardized video sequence through the acquisition unit, which switches between cameras based on the object's position. This combining approach maintains high video quality while presenting a unified output that simplifies analysis.
Solution Approach 2:
The acquisition unit acts as an intermediary that manages the complexity of multiple cameras by automatically switching between them based on motion detection data. This mediator handles the complex coordination tasks, making the multi-camera system easier to operate and analyze.
3Ease of manufacture
If manual recording with handheld cameras is used, then the equipment cost is reduced, but the ease of operation and analysis deteriorates
Solution Approach 1:
The system performs self-service through automated functions: the motion detector automatically tracks the object, the acquisition unit automatically switches between cameras, and the system automatically creates standardized video sequences. This automation eliminates manual operation while maintaining affordability through efficient resource use.
4Ease of operation
If standardized video recording is implemented, then the ease of analysis improves, but the device complexity increases
Solution Approach 1:
The system standardizes video recording by controlling parameters such as frame rate, resolution, and switching timing based on motion detection data. This parameter control creates uniform video sequences that are easier to analyze while managing complexity through systematic parameter management.
