Abstract
[Abstract]: Plant geometrical parameters such as internode length (i.e. the distance between
successive branches on the main stem) indicate water stress in cotton. This paper
describes a machine vision system that has been designed to measure internode
length for the purpose of determining real-time cotton plant irrigation requirement.
The imaging system features an enclosure which continuously traverses the crop
canopy and forces the flexible upper main stem of individual plants against a glass
panel at the front of the enclosure, hence allowing images of the plant to be captured
in a fixed object plane. Subsequent image processing of selected video sequences
enabled detection of the main stem in 88% of frames. However, node detection
was subject to a high false detection rate due to leaf edges present in the
images. Manual identification of nodes in the acquired imagery enabled measurement
of internode lengths with 3% standard error.
