Field phenotyping is the classical strategy to assess qualitative and quantitative agronomically important traits for field-grown plants. Many assessment methods are based on direct visual assessment or the manual use of portable measurement units. Considering the increasing amount of non-destructive, in many cases image-based measurement systems that have become available in the last few years, there is a strong tendency to use these non-destructive methods in the field as well as in a highly automated environment.
Compared to greenhouse and growth chamber phenotyping, outdoor measurement systems have to deal with the high variability of environmental growth conditions in the field, with harsh environmental conditions for the measurement systems and with the high dynamics of measurement conditions, especially the changing of light quality and quantity for any image-based measurement system.

Options to use LemnaTec scanalyzer systems for field phenotyping
Field Phenotyping - LemnaTec scanalyzer overhead systems are stationary portal crane systems, which can move a measurement support platform in a height of 3 to 6 meters over a field area of several hundred square meters. The platform is moved in a reproducible way with high precision to different positions, where visible light, near infrared and infrared cameras take images of the field from the top. 3D scanners can add a third dimension to the camera information. All components are housed and equipped with cooling options, so that the system may even be used in tropical and subtropical regions.
