Planting Machine Camera Timing for Precise Event Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural planting systems face inefficiencies in image capture due to the inability of image capture devices to capture relevant events at high enough frequency, leading to wasted computing and memory resources on unhelpful images, and reduced performance.
Innovation Solution
A timing signal is generated to indicate when events occur, allowing the image capture device to be actuated at optimal times to capture useful information, such as seed-to-soil contact or chemical application relative to seeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If image capture devices operate at high speed to capture all events, then event capture completeness is improved, but resource consumption and data utility worsen due to capturing irrelevant frames
Solution Approach 1:
The system generates timing signals in advance that indicate when specific events will occur during planting operations. These timing signals are used to pre-synchronize the image capture device, so that the device is activated only at the precise moment when relevant events occur, rather than continuously capturing all events at high speed.
Solution Approach 2:
Instead of continuous high-speed capture, the system uses periodic timing signals generated from planting machine operations to trigger image capture at specific intervals corresponding to actual events of interest, such as seed placement or material application moments.
2Loss of information
If image capture devices operate continuously at high speed, then all events are captured, but data relevance and processing efficiency worsen due to大量 irrelevant data
Solution Approach 1:
Timing signals are generated beforehand based on planting machine operation parameters, allowing the system to predict when events will occur. This preliminary timing information is used to synchronize image capture, ensuring that only frames containing actual events are captured, thereby eliminating irrelevant data before processing begins.
Solution Approach 2:
The system uses feedback from planting machine operation data (such as seed metering signals, material application signals, and operational status) to continuously adjust and refine timing signal generation, ensuring that image capture remains synchronized with actual events throughout operation.
3Loss of energy
If lower-speed image capture devices are used to reduce resource consumption, then resource efficiency is improved, but event capture accuracy worsens due to insufficient frame rate
Solution Approach 1:
The system pre-calculates timing signals based on known planting machine operation parameters and event frequencies. This allows lower-speed image capture devices to be synchronized precisely with events, capturing images at the exact moment events occur rather than relying on high frame rates to ensure capture.
Solution Approach 2:
The system changes the operational parameters of the image capture device by using timing-synchronized trigger signals instead of continuous operation. This allows the device to operate at lower speeds while maintaining event capture accuracy, as the device is activated only when needed based on external timing cues from the planting machine operations.
