Stereoscopic Imaging Device Synchronization via Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In stereoscopic imaging, existing systems using two imaging devices often fail to synchronize imaging timing and exposure periods accurately, especially during variable speed imaging, leading to inconsistencies between left and right channel images, resulting in a rough image, especially when capturing high-speed scenes.
Innovation Solution
The solution involves connecting the first and second imaging devices in a communicatable manner, where the first device transmits its imaging timing and exposure period data to the second device, allowing the second device to synchronize its imaging timing and exposure period, ensuring that both devices capture images at the same timing and exposure duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If variable speed imaging is performed with frame period changes, then imaging flexibility and adaptability are improved, but imaging timing synchronization between two imaging devices deteriorates
Solution Approach 1:
The system implements feedback by having each imaging device transmit its imaging timing data and exposure period data to the other device. This feedback mechanism allows the imaging devices to adjust their timing based on actual operational parameters, ensuring synchronization even during variable speed imaging modes.
Solution Approach 2:
The system performs preliminary actions by transmitting imaging timing data and exposure period data between imaging devices before actual image capture. This advance information exchange allows each device to pre-configure its imaging parameters to match the other device's timing, ensuring synchronized capture during variable speed operation.
2Device complexity
If imaging timing and exposure period are not synchronized between two imaging devices, then device complexity is reduced, but image quality deteriorates
Solution Approach 1:
The patent introduces intermediary data transmission mechanisms that carry imaging timing and exposure period information between devices. These intermediary signals act as mediators that coordinate the imaging operations of multiple devices without requiring complex direct synchronization hardware, thus maintaining image quality while managing system complexity.
3Manufacturing precision
If synchronized imaging is implemented between two imaging devices, then image quality is improved, but device complexity increases
Solution Approach 1:
The imaging timing data and exposure period data transmission serves multiple functions: it synchronizes imaging timing, coordinates exposure periods, and enables variable speed imaging operations. By making the data transmission mechanism multi-functional, the system achieves high-quality synchronized imaging without proportionally increasing device complexity.

AI summary
A first imaging device and a second image device are connected with each other in a communicatable manner, and data of imaging timing and data of an exposure period of the first imaging device are transmitted to the second imaging device. In the second imaging device, the imaging timing and the exposure period can be set based on the data of the imaging timing and the data of the exposure period which are received. Therefore, an image is taken by the first imaging device and the second imaging device with the imaging timing and the exposure period of the first imaging device agreeing with those of the second imaging device.
