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 .
In order to check the accuracy of equipment that collects macro-texture data, a method to compare ground truth measurements
with data collected by such equipment needs to be developed.
Finally, the classification accuracies obtained were compared through these data with reference to ground truth measurements for rabi crops and few associated landuse classes.
Training site were selected corresponding to five land cover (three crops and two other) classes based on ground truth measurements and the image pixels were classified as one of the five fixed classes.
