Fieldvision: automated geospatial plot grid creation system
FieldVision is a cutting-edge system that automates the creation of accurate geo-referenced plot grids using computer vision, CNNs, geospatial algorithms, and RTK GPS drone technology. It outputs a geoJSON file for use in GIS software, enhancing field mapping precision.
Overview
FieldVision revolutionizes the process of plot grid creation in agricultural fields by automating the delineation and segmentation of individual plots using advanced technologies. By integrating computer vision algorithms, convolutional neural networks (CNNs), geospatial algorithms, and RTK GPS technology, FieldVision delivers precise geospatial grids. This system not only enhances the accuracy of field mapping but also allows for detailed analysis of crop traits and indices using high-resolution multispectral imagery.
Technical specifications
Core Technologies:
- Computer Vision & CNNs: Utilizes sophisticated image processing to differentiate and mask crops from soil.
- Geospatial Algorithms: Ensures the accuracy of the grid with precise georeferencing.
- RTK GPS Drone Technology: Provides high-precision GPS data for field mapping.
Workflow:
- Input the number of columns and rows, or GPS coordinates of field corners.
- Process multispectral images to create an orthomosaic.
- Generate a geoJSON file of the plot grid which can be visualized in GIS software.
- Use deep learning models like U-NET, YOLOv9, and MobileNET for plot segmentation.
Technology readiness level
FieldVision is currently at Technology Readiness Level 3. The system has been validated in the lab and is undergoing further testing and development. Future validation includes using RTK-equipped UAVs to capture high-resolution images and testing various deep neural network models to enhance feature recognition and grid accuracy.
About Agrela Ecosystems
Agrela Ecosystems is a St. Louis-based agtech company founded in 2016 by plant scientists from the Donald Danforth Plant Science Center. The company develops PheNode, a scalable and modular environmental sensor platform designed to provide research-grade data collection. The system is physically reconfigurable for indoor and outdoor use and offers wireless scalability, allowing a single node to command a fleet of sensors covering large areas. It stands out by utilizing an open-platform approach that supports customizable sensor options, API access for data integration with platforms like Grafana, and features for automated data cleaning, which helps users avoid the limitations of traditional, closed remote sensing solutions.
This technology addresses a critical need for flexible, accurate, and field-deployable environmental data across various sectors, including agricultural research, specialty crop production, and smart transportation infrastructure. By providing continuous insights into conditions such as temperature, humidity, rainfall, and soil quality, Agrela enables data-driven decision-making for university researchers, private growers, and state highway departments. The company has gained national traction through partnerships, such as with the nonprofit The Ray to monitor highway roadside environments, and continues to expand its manufacturing and sales operations to support growing demand for its monitoring technology.
