The height dependence of the translation disparity (dy) can
clearly be seen by comparing it to the stereo disparity (dzx)
The dynamic test is performed on one surface only, sugar
beet with weed on uneven soil, Fig. 8h. The frame rate is set
to 5 Hz and the carriage is moved 10 times over the same
distance with various speeds. The total distance for each test
is 700 mm. The result is shown in Table II. There where
several frame that where missing in these tests due to
capturing problem. That error has been compensated for by
selecting the correct image pairs for analyze.
Fig. 13 shows a plot of the disparity representing the height
with respect to the estimated position for all 10 test runs.
