Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trigger signals are provided to multiple imaging devices via wireless connection with software processing, then the imaging devices can be controlled to capture images simultaneously, but the shutter timings may differ due to CPU processing loads and software delays
Solution Approach 1:
The patent replaces the software-based trigger processing system with a hardware-based direct connection system. The trigger generation circuit is directly connected to the imaging devices via cables, eliminating CPU software processing delays. The trigger signals are transmitted directly through hardware connections, ensuring precise synchronization of shutter timings across multiple imaging devices without the variability introduced by software execution.
2Ease of operation
If trigger signals are transmitted via wireless connection, then the system setup is simpler, but the synchronization precision deteriorates due to processing delays
Solution Approach 1:
The patent substitutes wireless trigger signal transmission with wired direct connections between the trigger generation circuit and imaging devices. This hardware-based direct connection eliminates the processing delays and synchronization issues inherent in wireless communication, ensuring precise shutter timing coordination while maintaining straightforward system configuration through direct cable connections.
3Adaptability or versatility
If multiple imaging devices process trigger signals through their own CPUs, then each device can independently capture images, but the shutter timings become inconsistent due to varying processing loads
Solution Approach 1:
The patent merges the trigger signal processing function into a centralized hardware trigger generation circuit that directly controls multiple imaging devices. Instead of each device independently processing trigger signals through its own CPU, the system uses a unified hardware circuit that generates and distributes trigger signals simultaneously to all imaging devices, ensuring consistent shutter timings while preserving each device's independent capture capability.
Data Source
AI summary
A first imaging device and a second imaging device are configured to directly receive a signal from a trigger generation circuit. A processing device processes first image data captured by the first imaging device in response to a first trigger signal, and second image data captured by the second imaging device in response to a second trigger signal. The first trigger signal and the second trigger signal are signals generated to start capturing images at the same time point. The processing device performs recognition processing of a target included in the first image data and the second image data.
