Furthermore, we plan to make a detailed accuracy analysis of the measurement method by comparing the stereo vision measurements with ground truth measurements made with either a coordinate measuring machine or a high accuracy vision system [19].
Ground Truth Measurements. During the GNSS signal acquisitions, two types of vegetation measurement were performed: VWC and crop height.
Figure 7 plots the resulting relationship between optical thickness, defined in (3), and the ground truth measurements of VWC.
Finally, the classification accuracies obtained were compared through these data with reference to ground truth measurements for rabi crops and few associated landuse classes.
