D. Experimental setup
A method of testing the proposed system was developed.
Two USB cameras, MV BlueFOX-120aC, are mounted on
the carriage of a metalworking lathe, as shown in Fig. 5. Then
they can be moved linearly in one direction over
approximately one meter with high precision. This setup
provides a ground truth, something that usually is difficult to
obtain in an outdoor field environment. A realistic surface is
created by using flower boxes with typical crops, in this case
sugar beet. These boxes can be fit into the lathe.
