Low Cost Techniques to Predict Strawberry Yield
in Field
In order to apply precision farming to high value crops
such as strawberries, a yield monitoring method is needed.
The yield monitoring system for high value crops should
be simple and relatively low cost for it to be adopted
by growers. In this paper, one indirect and one direct
method of monitoring strawberry yield were investigated.
For the indirect method, a computer vision method was
studied. The results of indirect method indicated that
although the contrast between strawberries' red color
and its surrounding can be used to predict yield, a
high resolution camera and more sophisticated algorithms
are needed to provide the desired accuracy. A strawberry
yield monitor for semi mechanical harvester were designed
and tested. This yield monitor directly measures the
yield. The results are discussed in the paper. Two software
programs were developed for this test. This includes:
1) Testing GPS accuracy version 1.01 and 2) Testing
Multiple GPS accuracy version 1.02.
