Solution Overview
Problem
Current methods for identifying and managing underperforming plants in corn stands are inefficient and costly, as they rely on manual counting and lack automated detection of plant characteristics, leading to resource consumption without optimal yield.
Innovation Solution
A system comprising an agricultural vehicle equipped with a sensor unit to capture images of the plant stand, a controller to process these images for determining plant characteristics, and an applicator to perform actions based on the processed data, enabling automated and efficient management of the plant stand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual counting and visual characterization methods are used to evaluate plant stands, then evaluation can be conducted with simple equipment, but the process is time-consuming, costly, and can only be performed on small subsamples infrequently
Solution Approach 1:
The patent replaces manual mechanical counting and visual inspection with an automated optical sensing system using cameras and image processing algorithms. The sensor unit captures images of the plant stand, and a controller processes these images to automatically count plants, identify characteristics, and evaluate stand conditions, eliminating the need for manual labor while significantly improving evaluation speed and frequency.
2Productivity
If unmanned aerial vehicles with camera technologies are used to count individual plants, then counting efficiency is improved, but the technology cannot detect and quantify characteristics of individual plants
Solution Approach 1:
The patent employs multiple sensor units with different capabilities positioned at various locations to capture different aspects of plant characteristics. The system uses specialized image processing algorithms that analyze local features such as plant height, leaf color, stem thickness, and canopy density at individual plant levels, enabling detailed characterization beyond simple counting.
Solution Approach 2:
The sensor unit and controller system is designed to perform multiple functions: counting individual plants, measuring plant height, assessing plant health through color analysis, detecting weed presence, and evaluating overall stand density. This multi-functional system replaces the single-function UAV camera by integrating various sensing capabilities into one comprehensive platform.
3Reliability
If heavy investment in planter technologies is made to increase Net Effective Stand percentage, then the number of effective plants increases, but the cost of equipment and implementation increases significantly
Solution Approach 1:
The patent implements a self-monitoring system where the sensor unit continuously captures images of the plant stand, and the controller automatically processes these images to identify and locate non-effective plants. The system generates real-time data about plant emergence, survival, and health without requiring external intervention, enabling farmers to make informed decisions about field management and resource allocation.
Solution Approach 2:
The system establishes a feedback loop by continuously monitoring plant stand conditions through image capture and processing, then using this information to guide management decisions. The controller analyzes plant characteristics and provides actionable insights about which areas need intervention, creating a closed-loop system that improves Net Effective Stand percentage through data-driven management rather than relying solely on expensive planter technologies.

AI summary
A plant stand management system includes a sensor unit configured to capture images of a plant stand, an applicator, and a controller communicatively coupled to the sensor unit and the applicator. The controller is configured to receive the captured images, process the captured images for determining one or more characteristics of the plant stand, generate one or more control signals based on the one or more characteristics, and send the one or more control signals to the applicator. The applicator is configured to perform at least one action on the plant stand based on the one or more control signals.
