Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems with fixed cameras struggle to generate high-definition free viewpoint video pictures, especially in environments where camera installation is difficult, due to issues like dead angles and occlusions, and cannot effectively handle the dynamic positioning of cameras to capture moving subjects.
Innovation Solution
A control device and method for movable type imaging devices that acquire and synthesize imaging information from multiple portable devices, such as drones, to calculate optimal arrangement information for generating free viewpoint video pictures, allowing for dynamic repositioning and improved image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed type imaging devices are installed at a site to photograph a free viewpoint video picture, then the imaging system is stable and reliable, but it becomes difficult to zoom out to capture moving photographic subjects within the angle of view, resulting in low definition images
Solution Approach 1:
The patent transitions from fixed type imaging devices to movable type imaging devices that can dynamically change their positions and orientations. The movable imaging devices can move to appropriate locations and adjust their imaging angles to capture moving photographic subjects, thereby maintaining high image definition while adapting to changing scene requirements.
Solution Approach 2:
The patent divides the imaging system into multiple movable imaging devices instead of using a single fixed device. By segmenting the imaging function across multiple mobile units, the system can capture subjects from various positions and angles simultaneously, ensuring high definition imaging of moving subjects without requiring a single fixed device to zoom out.
2Device complexity
If fixed type imaging devices are used to generate free viewpoint video pictures, then the system structure is simple, but it cannot effectively respond to user requests in environments where imaging devices cannot be installed at all times
Solution Approach 1:
The patent employs movable imaging devices that can be deployed to specific locations temporarily rather than being permanently installed. These devices can move to appropriate positions, perform imaging tasks, and then be relocated, enabling the system to adapt to environments where permanent installation is not feasible while maintaining operational simplicity through automated control.
Solution Approach 2:
The movable imaging devices are equipped with autonomous navigation and positioning capabilities, allowing them to independently move to designated locations and perform imaging tasks without requiring complex installation infrastructure. The devices can self-position and self-adjust their imaging parameters, reducing the need for permanent installation while maintaining system simplicity.
3Area of stationary object
If monitoring cameras are arranged in a monitoring system to eliminate dead angles, then the coverage area is improved, but it cannot satisfy the peculiar requests of free viewpoint video pictures such as preventing cameras from being reflected in each other
Solution Approach 1:
The patent uses movable imaging devices that can dynamically adjust their positions and orientations to achieve optimal imaging angles for free viewpoint video pictures. Unlike fixed monitoring cameras, these movable devices can prevent mutual reflections by positioning themselves appropriately and adjusting their imaging directions, while still maintaining comprehensive coverage area through coordinated movement of multiple devices.
