Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image analysis methods for loaded objects on devices face challenges such as decreased accuracy and increased processing time due to single region analysis or boundary overlap issues when dividing images into multiple regions.
Innovation Solution
A method and apparatus for analyzing iron scraps through image segmentation by determining a target region, converting it into a rectangular shape, and segmenting it based on a quotient-derived number of segmentations to obtain non-overlapping segmented images, with adjustments for remaining regions to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the entire image is analyzed as a single region, then the analysis process is simple, but the accuracy of the analysis decreases and processing time increases
Solution Approach 1:
The patent divides the loading device into multiple regions along the conveyor direction, with each region having a width of 100mm to 1000mm. This segmentation allows the system to analyze specific areas more accurately while reducing the overall processing complexity by focusing on smaller, manageable sections rather than the entire loading device at once.
2Device complexity
If the entire image is analyzed as a single region, then the processing is straightforward, but the processing time increases
Solution Approach 1:
By segmenting the loading device into multiple regions along the conveyor direction, the system can process each region independently and more quickly. The patent specifies that each region should have a width of 100mm to 1000mm, which optimizes the balance between processing speed and analysis thoroughness.
3Measurement precision
If the image is divided into multiple regions, then the analysis accuracy may improve, but boundary overlap issues arise where objects at edges are included in multiple regions
Solution Approach 1:
The patent extracts and removes boundary lines from the segmented regions. Each region is defined with specific left and right coordinates, and the boundary lines are excluded from the region definitions. This ensures that objects near boundaries are assigned to only one region, eliminating duplication and improving analysis reliability.
Solution Approach 2:
The patent applies different processing qualities to different regions. By defining regions with specific width constraints (100mm to 1000mm) and excluding boundary lines, the system ensures consistent and reliable analysis across all regions while maintaining the benefits of segmentation.
4Measurement precision
If the image is divided into multiple regions, then more detailed analysis is possible, but a single object may be improperly divided during analysis
Solution Approach 1:
The patent extracts boundary lines from the region definitions and ensures that objects are not split across region boundaries. By defining regions with clear coordinate systems and excluding boundary lines, the system maintains complete object integrity while still enabling detailed analysis through segmentation.

AI summary
A method and apparatus for analyzing iron scraps through image segmentation is provided. The method includes receiving, by a receiving circuit, a loaded state image from a camera when iron scraps are loaded onto a loading device, and, by a processor, determining a target region including the iron scraps in the loaded state image, simplifying the target region, converting the simplified target region into a rectangular region, determining first and second lengths representing lengths of two different sides of the rectangular region, the second length greater than the first length, determining a number of segmentations of the target region based on a quotient obtained by dividing the second length by the first length, segmenting the loaded state image based on the number of segmentations to generate a plurality of segmented images, and performing image analysis on the plurality of segmented images to provide analysis results of the iron scraps.
