Solution Overview
Problem
Current methods for semantic segmentation of farmland images in precision agriculture face challenges such as inadequate segmentation accuracy, loss of image details, and lack of spatial consistency due to insufficient consideration of pixel relationships, especially in complex and dynamic farmland environments.
Innovation Solution
A convolution neural network (CNN) is constructed using a multi-resolution network approach with ENet architecture, incorporating batch normalization and randomization to enhance image segmentation, and combining parameters of batchnorm layers with convolution layers for improved testing speed and accuracy, while utilizing a diverse dataset with varied resolutions and preprocessing techniques to refine edges and maintain spatial consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional deep learning methods are used for farmland image segmentation, then the segmentation process can be completed, but the segmentation accuracy is insufficient and image details are lost
Solution Approach 1:
The patent divides the image processing into multiple resolution levels (coarse segmentation and fine segmentation stages). The first stage performs rough segmentation at lower resolution to capture overall structure, while the second stage refines boundaries and recovers details at higher resolution, thereby preserving image details while achieving accurate segmentation.
Solution Approach 2:
The patent introduces multi-resolution processing as an additional dimension to the segmentation process. By processing images at different resolution levels and combining results, the system achieves both accurate segmentation boundaries and preserved fine details that would be lost in single-resolution processing.
2Reliability
If traditional deep learning methods are used for farmland image segmentation, then the segmentation can be performed, but spatial consistency is lacking due to insufficient consideration of pixel relationships
Solution Approach 1:
The patent merges convolutional neural network operations with pixel relationship analysis. By integrating local and contextual information processing within the CNN architecture, the system achieves spatial consistency in segmentation results while maintaining a practical network structure that can be implemented efficiently.
Solution Approach 2:
The patent introduces multi-resolution feature maps as intermediary representations that capture pixel relationships at different scales. These intermediate features serve as mediators between raw input pixels and final segmentation labels, enabling the network to consider contextual relationships while maintaining computational efficiency.
3Measurement precision
If complex network structures are used to improve segmentation accuracy, then better results can be achieved, but testing speed decreases
Solution Approach 1:
The patent segments the network processing into two stages with different complexity levels. The first stage uses a simpler architecture for coarse segmentation at higher speed, while the second stage applies more complex operations only to refine boundaries and details, thereby achieving high accuracy without sacrificing overall processing speed.
Solution Approach 2:
The patent applies complex computational operations partially - only in the second refinement stage and only where needed for boundary improvement. This partial application of complex operations achieves high accuracy where necessary while maintaining faster processing in regions where simple operations suffice.
