Illustration of the imaging and analysis pipeline. (A) Aerial platform Zeppelin NT, (B) handheld sensor array consisting of three cameras, (C) images derived by: a consumer camera (RGB), a modified consumer camera for vegetation detection (B + NIR) and an infrared camera (Thermography, IR). Squares indicate location of field markers. (D) Round black metal plates serve as field markers (left) for automatic detection and subsequent clipping of the area of interest (AoI) and trapeze correction of the raw images (middle). Co-registered tiff images for the RGB composite and the three data channels IR, B and NIR (right). (E) Three steps of image procession: mask to segment plant from soil pixel (left), mask to identify plots (middle) and a combined output map of NDVIPlant values within plots in false colour (right). The shown images represent one of three parts of the field separated for measurement purposes, details described in the material section. See Additional file 1 for a complete image of the experiment.
