Example: how color video can provide an easy way to gather large volumes of crop phenotyping data in the field Context elements: Imagery inherently contains spatial information across the pixel value grid array Imagery is helpful in meta data collection and quality control documentation Visible light cameras provide plant relevant information in their RGB color space Photogrammetric angular distance calculations across viewpoints reconstructs 3D The $150 Transcend DrivePro 220 automobile dash camera product yields a GPS stamped 30Hz 1080p RGB video stream and 1Hz NMEA text file Mounted nadir on the “Storm” PSC, canopy color video can be useful in vegetation cover analysis and support field based high throughput crop phenotyping

Original image - camera full FOV frame includes tracks and shade

Single processed video frame with distortion correction and center cropped to inner rows

Extracted and processed video frames are input to the MS ICE for stitching

Resultant MS ICE stitched images taken from corrected video frames show a full plot nadir image mosaic (above), with close-up resolution pixilation visible zoom (right)

Plot level proximal imagery can be compared to height, and NDVI measurements for additional understanding

Plot level proximal imagery could be tiled to a field scale, and compared with mapped NDVI field measurements
