The carriage is positioned on the start position at one end
of the flower box. Image pairs are captured while the carriage
is moved to the other end of the flower box. This gives a total
distance of 700 mm in y-direction for each test. The space in
x-direction is so limited that no tests were possible to make in
this direction.
Two different test methods are used, first for accuracy and
variance calculation, which require reference of each image
captured, and second for evaluating the dynamic
performance. For the first method, an image pair from the stereo cameras is acquired and the carriage is moved 10mm
for acquiring next pair. The cameras are not moved while the
images are captured, which will eliminate errors from camera
synchronization and motion blur. By capturing images at
constant distance, the speed will be constant and the position
for each image will be known. A drawback of this method is
that the variance in the manual positioning each 10 mm will
be included in the result. The accuracy of the positioning is
approximately 0.1 mm. The mean error will be small due to
the long distance.
