Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing logging practices lack objective verification of compliance with logging plans, relying heavily on self-assessment and manual checks, which can lead to inaccuracies and inefficiencies.
Innovation Solution
A determination apparatus and method utilizing satellite imagery and planning data to objectively assess logging appropriateness by comparing pre- and post-logging images against logging plans, estimating logged regions and amounts, and specifying tree species and forest age, with automated output to relevant stakeholders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual checks and self-assessment are used for logging compliance verification, then the process is simple and requires minimal equipment, but the accuracy and reliability of determination are low
Solution Approach 1:
The patent replaces manual visual inspection and self-assessment with automated image processing technology. Satellite images and aerial photographs are processed through computer algorithms to automatically detect logging areas, calculate volumes, and determine compliance, substituting human judgment with mechanical computation to improve accuracy and objectivity.
Solution Approach 2:
The patent creates accurate copies of the forest environment through satellite imaging and aerial photography. These image copies serve as digital representations that can be analyzed without physical presence, allowing for precise measurement and determination of logging compliance while reducing the need for complex field verification equipment.
2Reliability
If automated image analysis is implemented for logging determination, then determination accuracy and objectivity improve, but the complexity of the system increases
Solution Approach 1:
The patent designs a multi-functional determination system that can handle various logging scenarios using the same core image processing technology. The system can determine both area-based compliance and volume-based compliance, process different types of images (satellite and aerial), and generate multiple types of determination results, reducing the need for separate specialized systems for each function.
Solution Approach 2:
The patent introduces image data as an intermediary between the physical logging activity and the compliance determination. Satellite images and aerial photographs serve as intermediate representations that capture the state of the forest, allowing the determination system to analyze compliance indirectly through these mediators rather than requiring direct measurement of all parameters.
3Measurement precision
If comprehensive image data analysis is performed to estimate logging region and amount, then measurement precision improves, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary actions by acquiring satellite images and aerial photographs before the actual determination process. These images capture the forest state at different times, allowing the system to pre-identify potential logging areas and prepare reference data that accelerates the subsequent analysis and estimation processes.
Solution Approach 2:
The patent segments the determination process into distinct stages: image acquisition, image processing, logging area detection, volume calculation, and compliance determination. This segmentation allows each stage to be optimized independently and enables parallel processing of multiple images or areas, reducing overall processing time while maintaining comprehensive analysis.
