UAV Crop Scouting and Spot Spraying for Precision Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural practices face challenges in efficiently and cost-effectively controlling weeds and pests in crop fields, as broad-spectrum herbicides are expensive and can contaminate water supplies, while pests reduce crop yields, necessitating a precise and targeted approach.
Innovation Solution
A UAV system equipped with a microprocessor, transceiver, and onboard cameras for autonomous or operator-controlled navigation, using databases to identify and apply precise amounts of herbicides and pesticides, avoiding overspray and minimizing environmental impact by targeting specific weeds and pests with spot treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broad-spectrum herbicide is applied to control weeds, then weed control effectiveness is improved, but cost increases and environmental contamination risk worsens
Solution Approach 1:
The patent applies spot treatment by targeting herbicide application to specific locations where weeds are detected by the UAV's imaging system, rather than uniform broad-spectrum application. This localized approach maintains weed control effectiveness while reducing overall herbicide usage and environmental contamination risk
Solution Approach 2:
The patent replaces manual or mechanical broad-spectrum spraying with an automated UAV-based system that uses image recognition to identify weeds and applies herbicide precisely to targeted locations, substituting mechanical uniform application with intelligent selective application
2Reliability
If broad-spectrum herbicide is applied to control weeds, then weed control effectiveness is improved, but cost increases
Solution Approach 1:
The system applies herbicide only to specific locations where weeds are detected, rather than treating the entire field uniformly. This localized spot treatment maintains effective weed control while significantly reducing the quantity of herbicide required, thereby lowering costs
Solution Approach 2:
The patent applies herbicide partially - only to the extent necessary for controlling detected weeds - rather than applying excessive amounts across the entire field. This partial action approach reduces herbicide consumption and cost while maintaining control effectiveness
3Quantity of substance
If precise spot treatment is applied to control weeds, then herbicide usage is reduced, but device complexity increases
Solution Approach 1:
The UAV system performs multiple functions: it captures images, processes them to detect weeds, navigates to target locations, and applies herbicide. By integrating these functions into a single multi-functional platform, the patent manages complexity while achieving precise spot treatment and reduced herbicide usage
4Productivity
If UAV performs autonomous crop monitoring and treatment, then productivity is improved, but device complexity increases
Solution Approach 1:
The UAV system operates autonomously, performing self-navigation, self-monitoring of crop conditions through imaging, self-detection of weeds, and self-application of herbicide. This self-service capability improves productivity by eliminating the need for continuous human intervention, though it increases device complexity
Solution Approach 2:
The system uses image recognition technology to detect weeds and crop conditions, then uses this feedback information to guide precise herbicide application. This closed-loop feedback mechanism enables autonomous operation and improves productivity while managing the complexity through intelligent control
Data Source
AI summary
A software process for controlling a configurable UAV that includes a plurality of databases of crop plants, herbicides, insecticides and weeds. An area is defined to be treated. Thereafter, a scout UAV with an on-board camera is flown over the pre-defined area. Images detected by the camera are compared with the crop, pest and weed databases to respectively identify the crop plants, insects, and weeds. The insects and weeds are then subjected to a spot blast of pesticide/herbicide to kill them. Thus, the process results in a more efficient application of treatment chemicals which leads to less adverse environmental impacts associated with the use of pesticides and herbicides.
