Agro-sensor systems for outdoor plant phenotyping platforms in low and high density crop field plots

摘要

Sensors and the corresponding system technology are key components in the automated treatment of individual plants as well as for plant phenotyping in field trials. Based on varying dimensions of plant structures between different kinds of plants in combination with the spatial resolution of sensor systems, the authors introduce a differentiation between "high" and "low" density crop field plots related to the automated phenotyping process. Based on experiences in research and application of sensor systems in agriculture the authors are developing phenotyping platforms for both of the above mentioned categories. The multi-sensor-platform "BreedVision" specialized for "high density crop field plot"-phenotyping of Triticale (x Triticosecale Wittmack) and the autonomous phenotyping robot "BoniRob" as an example for "low density crop field plot"-phenotyping with a first field of application in maize. The platforms use several different sensor systems for the detection of morphological and spectral signatures. In this paper two of them, light-curtain imaging and laser distance sensors with first outdoor measurement results, were described in detail.
