The objective of this study was to develop a crop growth mapping system. A color CCD camera mounted on an agricultural vehicle acquired the crop rows' video images. An entire image of the crop rows was produced by montaging continuous video images. An index named as CIVE (Color Index of Vegetation Extraction) was tested to extract the features of the crops from the images and the overlap positions between the continuous two images were detected.
The information of the crop positions in the field was also an important index to make the crop growth map. This position accuracy in the entire crop rows' image was studied. The maximum error of positioning was ±1.5m, and the average of its R. M. S, error was calculated as 0.8m in the entire image of the crop rows of 160m length. This entire image was produced by montaging 640 images. It was summarized that this positioning accuracy was enough to produce the crop growth map.
