## Abstract

A phenotyping device, method and system for measuring phenotypic traits of one or more plants in a target canopy, wherein the includes a canopy spreader for spreading the target canopy, a camera unit, a means for controlling the angle and the distance of the camera unit in relation to the canopy spreader, an electronic control unit for controlling the camera unit. The phenotyping device, method and system enables recording the raw data from the target canopy during a data collection session including information of the plants that are not visible to a camera unit without spreading the canopy.
