Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are physically fixed at different locations in a device, then the device can capture images from different perspectives, but the device cannot select the optimal camera pair for stereo vision
Solution Approach 1:
The patent implements dynamic camera selection by allowing the system to switch between different camera pairs based on the detected object's characteristics. The processor determines the optimal subset of cameras from the plurality of cameras based on object properties such as size, distance, and type, enabling the system to adaptively optimize stereo vision accuracy for different imaging scenarios rather than using a fixed camera configuration.
2Ease of manufacture
If a fixed pair of cameras is used for stereo vision, then the device structure is simple, but the stereo image quality is suboptimal for different objects
Solution Approach 1:
The patent segments the camera system into multiple independent camera modules that can be selectively activated. By dividing the plurality of cameras into different subsets based on imaging scenarios, the system maintains a simple overall structure while enabling optimized camera pair selection for different objects, thus resolving the contradiction between structural simplicity and image quality.
3Measurement precision
If the device switches between different camera subsets for different objects, then stereo vision accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple camera subsets that are optimized for different imaging scenarios. The system prepares these camera groups in advance based on object characteristics such as size, distance, and type, allowing rapid switching without complex real-time calculations, thus improving stereo vision accuracy while managing system complexity.
4Measurement precision
If all cameras are always active to ensure optimal coverage, then image quality is maintained, but energy consumption increases
Solution Approach 1:
The patent extracts and activates only the necessary subset of cameras required for optimal stereo vision based on the detected object's characteristics. By taking out and using only the relevant cameras from the plurality of cameras rather than keeping all cameras active, the system maintains high image quality while significantly reducing energy consumption for the camera subsystem.

AI summary
Aspects relate to rotationally switching between cameras to provide stereo vision of an object. A device may include one or more memories configured to store one or more images including an object and a plurality of cameras. The plurality of cameras may be configured to capture the one or more images including the object. The device may further include one or more processors coupled to the one or memories, in which, the one or more processors are configured to: based upon an object detected, determine a subset of cameras from the plurality of cameras to provide stereo vision of the object; and rotationally switch between a previously selected subset of cameras for a previous object to the determined subset of cameras for the object to provide stereo vision of the object.
