Fig 7. Schematic diagram of the segmentation and phenotype extraction of the top-view of maize seedlings obtained using the field orbital phenotype platform and UAV.

In (a), a field track phenotypic platform was used to obtain the top-view images. In addition to the protected rows, a total of 13 varieties of maize plants were included (marked with a serial number in the fig). (b) For the top-view of the maize population obtained using the UAV, the image contains 216 maize plants of the same cultivar.
