Crop Counting from Overlapping Field Images Without Double Counting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for calculating the number of crops in a farm field are inaccurate due to potential omissions or redundancies in image analysis, particularly when multiple images are captured with overlapping regions.
Innovation Solution
An information processing device and method that identifies overlapping and non-overlapping regions in multiple images captured by imaging devices, using coordinate transformation and image synthesis to accurately count crops by integrating and calculating the number based on these regions.

Engineering Contradiction Analysis
1Area of stationary object
If multiple images are captured to calculate the number of crops, then the coverage area increases, but the accuracy of crop counting decreases due to omissions or redundancies
Solution Approach 1:
The patent divides the image processing task into three distinct segments: identifying overlapping regions, identifying non-overlapping regions, and separately calculating crop numbers in each region. This segmentation allows for precise handling of each area type, preventing both omissions and duplications in crop counting while maintaining comprehensive coverage across multiple images.
2Productivity
If simple image processing is used, then the processing speed is fast, but the crop counting accuracy is low due to omissions or redundancies
Solution Approach 1:
The patent performs preliminary identification of overlapping and non-overlapping regions before conducting crop detection and counting. This preliminary action organizes the processing workflow in advance, allowing subsequent crop counting to be performed efficiently on pre-defined regions without requiring complex real-time adjustments, thus maintaining both speed and accuracy.
