Wearable AR Guidance for Forestry Tree Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current forestry management methods lack efficient and safe ways to select and cut trees, as they rely on physical markings and manual surveys, which can be error-prone and do not provide real-time guidance to operators.
Innovation Solution
A forestry management device that uses wearable computing devices to receive and display information about selected trees, including location data, felling direction, and safety thresholds, using processing circuitry to generate tree maps and provide augmented reality overlays for operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical markings and manual surveys are used to select and mark trees for cutting, then the method is simple and does not require complex equipment, but the accuracy of tree selection is reduced and real-time guidance to operators is not provided
Solution Approach 1:
The patent creates a digital copy of the forest environment through a virtual site map that mirrors the physical site map. Trees are represented as virtual objects with digital identifiers and attributes. This virtual representation allows for precise selection and tracking of trees without requiring complex physical marking systems, resolving the contradiction by providing high accuracy through digital replication rather than physical complexity.
Solution Approach 2:
The wearable computing device acts as an intermediary between the forestry management system and the operator. It receives data from the system (tree information, selection status, guidance) and presents it to the operator through the wearable interface. This intermediary enables real-time information delivery without requiring the operator to carry or interact with complex equipment, thus improving accuracy while managing system complexity.
2Ease of operation
If physical markings are used to indicate selected trees, then the method is easy to implement, but error-prone and does not provide real-time guidance to operators
Solution Approach 1:
The system implements feedback by providing real-time information to the operator through the wearable computing device. When a tree is selected or marked, the system communicates this status back to the operator immediately, rather than relying on physical markings that may be missed or misinterpreted. This feedback loop increases reliability by ensuring the operator has accurate, up-to-date information about which trees are selected, while maintaining ease of operation through automated system-driven notifications.
3Productivity
If manual surveying and charting is used to select trees, then the equipment required is simple, but the productivity and efficiency of forestry operations is reduced
Solution Approach 1:
The patent replaces manual mechanical processes (physical surveying, charting, and tree marking) with an automated electronic system. The wearable computing device and forestry management system automatically track, select, and communicate tree information, eliminating the need for manual surveying equipment and paper-based charting. This substitution dramatically improves productivity by automating previously labor-intensive tasks, while the modular architecture of the system manages complexity through standardized interfaces and protocols.
Data Source
AI summary
A forestry management device is provided including processing circuitry configured to receive an indication of a selected tree, receive selected tree location data associated with the selected tree, receive operator location data associated with an operator, and cause information associated with the selected tree to be displayed on a wearable computing device.
