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 leaf imaging system is disclosed which includes a leaf-handling subsystem which includes a first leaf contactor and a second leaf contactor and configured to receive a leaf in therebetween, and an encoder coupled to one of the first or second leaf contactors, the encoder configured to selectively trigger a camera corresponding to motion of the leaf. The leaf imaging system further includes a lightbox in communication with the leaf-handling subsystem and configured to provide light to the leaf as the leaf passes between the first and the second leaf contactors; and a controller in communication with the encoder, the camera, and the lightbox and configured to operate the camera based on output of the encoder.
