Agricultural Vehicle Camera Image Retrieval by Time and Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for electronically managing agricultural crop cultivation struggle with capturing images of specific targets, such as equipment failures or weeds, while a worker is on a moving vehicle, as the timing of target detection does not align with the camera's field of view, leading to unnecessary image capture and increased effort in identifying relevant images.
Innovation Solution
An information processing apparatus that chronologically manages images from a camera mounted on a moving object, allowing users to input instructions for specific report content, and identifies suitable images based on time and position information, using a candidate image group selection and object detection techniques to quickly retrieve relevant images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a camera is mounted on a moving vehicle to capture images while the worker is on the vehicle, then the worker does not need to get off the vehicle to image incidents, but the timing of target detection does not align with the camera's field of view, leading to missed targets
Solution Approach 1:
The system performs preliminary actions by continuously capturing images and storing them with timestamp and position information before the worker issues an instruction. When the worker discovers a target and inputs an instruction, the system can retrieve images captured around that time, ensuring the target is captured even though the worker did not trigger the camera at the exact moment of discovery.
2Reliability
If the camera constantly captures images to prevent missing targets, then all targets can be captured, but the number of recorded images increases considerably, requiring more time and effort to identify relevant images
Solution Approach 1:
The system extracts only the necessary information from the large set of captured images by using timestamp and position data. When a worker issues an instruction, the system extracts and displays only the images captured around the instruction time, filtering out the vast majority of irrelevant images and enabling quick identification of the target.
3Quantity of substance
If images are captured only when instructed by the worker, then the number of recorded images is reduced, but the target may not be within the camera's angle of view at the instruction timing
Solution Approach 1:
The system performs preliminary image capture and stores images with timestamp and position information before the worker issues an instruction. This allows the system to retrieve images captured just before or after the instruction time, ensuring the target is captured even if it moves in or out of the camera's field of view between the worker's discovery and the instruction.
