Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D tour photographing systems face challenges in indoor location tracking and 360-degree spatial capturing, requiring separate equipment for image photography and location measurement, leading to errors and inefficiencies due to mismatched photographing points and directions, especially in indoor spaces where GPS is unavailable.
Innovation Solution
A 3D tour photographing apparatus that integrates a camera module for 360-degree image capture, a location tracking module using SLAM techniques, and a tilt unit to adjust the position and angle between the camera and location tracking modules, along with a control module to derive movement paths and provide notifications for error correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate equipment is used for image photographing and location measurement, then device functionality is provided, but measurement precision deteriorates due to mismatched photographing points and directions
Solution Approach 1:
The patent combines the image photographing module and location measurement module into a single integrated 3D tour photographing apparatus. The photographing unit captures images while the location tracking unit simultaneously determines position and movement information, ensuring both functions operate from the same physical platform and temporal moment, thereby eliminating mismatches between photographing points and location data points.
Solution Approach 2:
The integrated apparatus serves multiple functions simultaneously: it captures images for 3D tour creation while concurrently performing location tracking and movement detection. This multi-functional design allows a single device to replace separate equipment, improving both operational efficiency and measurement precision through unified data collection.
2Adaptability or versatility
If GPS is used for location tracking, then outdoor location tracking is provided, but adaptability deteriorates because GPS cannot be used in indoor spaces
Solution Approach 1:
The patent replaces GPS (which relies on satellite signals) with alternative location tracking methods suitable for indoor environments. The location tracking unit uses inertial measurement units (IMU), accelerometers, gyroscopes, and visual odometry techniques to determine position and movement without requiring external satellite signals, enabling reliable tracking in both indoor and outdoor settings.
Solution Approach 2:
The system changes the operational parameters of location tracking by switching from satellite-based GPS to sensor-based inertial and visual tracking methods. This parameter change allows the system to adapt to different environments (indoor/outdoor) by using appropriate tracking methodologies for each context, maintaining reliability across diverse operating conditions.
3Ease of operation
If photographing points and directions are not matched, then flexibility in photographing is provided, but time and effort increase for finding and comparing corresponding 3D images
Solution Approach 1:
The patent implements feedback mechanisms where the location tracking unit continuously provides position and movement information that is directly correlated with captured images. This feedback loop enables automatic matching of images to their corresponding location and orientation data, allowing users to quickly retrieve and compare specific 3D images without manual searching, significantly reducing time and effort while maintaining photographing flexibility.
