Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If computer vision and image matching techniques are used for camera localization and synchronization, then synchronization accuracy can be improved, but processing time and system complexity increase significantly
Solution Approach 1:
The patent replaces computer vision-based localization with wireless signal-based localization (WiFi, LiFi, cellular). Instead of using image processing and computer vision algorithms to determine camera positions, the system uses wireless communication transceivers to obtain geographical location data and orientation information directly from device sensors and network triangulation, dramatically reducing processing time while maintaining synchronization accuracy
Solution Approach 2:
The patent introduces wireless communication signals as an intermediary medium for camera localization. Rather than directly processing visual data from cameras, the system uses wireless signals (WiFi, LiFi, cellular) as a mediator to transmit location and orientation information, enabling fast and accurate camera positioning without the computational burden of computer vision
2Measurement precision
If computer vision based localization is used, then camera position accuracy can be improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent substitutes complex computer vision processing with simpler wireless communication-based localization. The system uses readily available wireless transceivers and sensor data (GPS, accelerometer, gyroscope) to determine camera positions and orientations, eliminating the need for complex image matching algorithms and reducing overall system complexity while maintaining positioning accuracy
Solution Approach 2:
The patent leverages the multi-functionality of modern mobile devices, which already contain wireless communication capabilities and sensors for other purposes. The same WiFi, LiFi, or cellular transceivers used for communication are also used for localization, and the same sensors used for device orientation control are used for camera positioning, eliminating the need for dedicated computer vision hardware
3Manufacturing precision
If 3D model creation is used for multiview imaging, then visualization quality can be improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary localization and synchronization of cameras using wireless communication data before the multiview imaging process begins. By pre-determining camera positions and orientations through fast wireless signal processing rather than real-time 3D model creation, the system enables real-time interactive visualization without the computational burden of on-the-fly 3D reconstruction
