Abstract: A method for spatial analysis of leaf images is disclosed which includes acquiring one or more leaf images of plants, generating 3-dimensional (3D) images from the acquired one or more images from spectral heatmaps, identifying a stem and a plurality of veins, identifying i) one or more of valleys and ridges as regions between two consecutive veins from the plurality of veins, or ii) one or more of peaks and valleys as regions between two consecutive veins from the plurality of veins in the one or more generated 3D images, calculating average slopes in the generated 3D images between i) one or more of peak-to-valley, or ii) ridge-to-valley for the veins, calculating a nitrogen index based on the calculated average slopes, if the calculated average slope is between two thresholds, communicate to a user to add a predetermined chemical to the plants.

Abstract: A root imaging system is disclosed which includes a robotic arm, a camera coupled to the robotic arm, the robotic arm configured to insert the camera into the soil at predefined coordinates, a processor system configured to receive user-defined data about a plant of interest, define insertion points about the plant of interest based on the user-defined data, control the robotic arm to thereby insert the camera into the soil at defined insertion points, obtain images from the camera positioned at the insertion points, analyze the images for presence of roots, and identify the images having roots and combine that with image 3D location information for 3D structure reconstruction of the entire root structure.
