Polarimetric peanut drone images of peanut crop infected with leaf spot

This dataset contains polarization-based aerial imagery and plot-level phenotypic measurements collected to evaluate the relationship between leaf spot severity and polarization signatures in peanut (Arachis hypogaea). The study was conducted at two North Carolina research stations—the Upper Coastal Plain Research Station (UCPRS) and the Peanut Belt Research Station (PBRS)—using an automated drone imaging system developed by North Carolina State University. A Lucid Triton camera equipped with a Sony IMX250MZR polarization-sensitive CMOS sensor was mounted on a UAV to acquire Stokes vector–derived Degree of Linear Polarization (DOLP) and S0 intensity images over peanut breeding trials. The research goal was to determine whether DOLP values increase with the severity of leaf spot, a major foliar disease affecting peanut production. Raw DOLP and S0 imagery from each location is provided alongside an Excel file containing expert-assigned leaf spot visual scores, plot-level mean DOLP values,..., This data set was collected using a custom-fitted drone with a Sony IMX250MZR polarization-sensitive sensor. Field trials were held where the peanut was infected with leaf spot and scored in accordance with the traditional Modified 9-Point Scale. This protocol allowed us to develop this data set, which associates polarization intensity with infection of the peanut.

This contains the raw data from the paper \"Drone-Based Polarization Imaging System for Leaf Spot Severity Determination in Peanut Plants\" by Larsen, Dunne, Austin, Newman, and Kudenov.

The file \"PlotData.xlsx\" contains all the raw plot data from the field trials. This file contains two sheets, one for the UCPS and one for the PBRS locations. Each sheet has four columns: The first is the plot number at the field, the second is the visual score associated with the plot, the third is the mean DOLP value, and the fourth is the RGB Defoliation for the plot.

The PolarizationProcessingCode folder includes all the MATLAB scripts and .mat data files used to process images from the Triton camera. The .mat file includes the coefficient of determination for each pixel that was characterized.

Each .zip file contains the raw images from the final polarization drone imaging...,
