Abstract: A method and system are disclosed for providing consistent images of leaves of plants, including articulating a lower case of a housing with respect to an upper case via an imaging chamber articulation mechanism from i) a closed state to ii) an open state, the articulable space forms an imaging chamber which is dark when the imaging chamber articulation mechanism is in the closed state, placing the leaf within the imaging chamber, articulating the imaging chamber articulation mechanism to the closed state, activating one or more light sources, actuating a linear actuator to thereby linearly move a camera from i) an initial position to ii) an end position, obtaining images from the camera, re-actuating the linear actuator to thereby linearly move the camera from the end position to the initial position, re-articulating the lower case to the open state, and removing the leaf.

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.
