1. A phenotyping device for measuring phenotypic traits of one or more plants in a target canopy comprises:
one or more shafts arranged, when the phenotyping device is moved, to move parallel to a surface of a ground and partly in contact with the target canopy for revealing the one or more plants for imaging in the target canopy;
one or more camera units;
a means for controlling the angle and the distance of the one or more camera units in relation to the one or more shafts arranged to maintain the position and orientation of the one or more camera units fixed relative to the shaft;
an electronic control unit for controlling the camera unit, the electronic control unit being further configured to:
defining an input data specification for a raw data collected by the one or more camera units of the phenotyping device from a current set of raw data collection targets;
defining a use-orientation-height specification;
defining a device-specific device-location-angle specification;
defining a use movement specification;
adjusting at least one parameter of the means for controlling an angle and a distance of the one or more camera units in relation to the one or more shafts according to the device-specific device-location-angle specification for maintaining the position and orientation of the one or more camera units fixed relative to the shaft;
initiating the raw data collection session;
moving the one or more shafts of the phenotyping device partly in contact with the one or more plants in the target canopy according to the defined use-orientation-height specification and according to the use movement specification for revealing the one or more plants for imaging in measuring phenotypic traits of the one or more plants;
recording the raw data of the one or more plants in the target canopy while moving the device in contact with the target canopy according to the use-orientation-height specification and according to the defined use movement specification;
processing the recorded raw data to estimate the phenotypic traits of the one or more plants in the target canopy.
