| Summary: | Mobile sensor devices offer great opportunities for automatic scene analysis and object recognition. Nowadays a new generation of
ranging devices is available, like laser scanners which are small and light weighted. Concerning these improvements specific
applications can be tackled. In this contribution we focus on vineyard monitoring for detecting and counting grape berries with a
small, lightweight and low cost multi-echo laser scanner. Therefore a Hokuyo UTM-30LX-EW laser range finder is utilized for
capturing the data in close range up to 1m. In order to process the data the following methodology is proposed: after smoothing and
morphological techniques are applied on the laserscanning intensity and range images the number of visible grape berries is
determined from the resulting segments. The approach performs with a detection accuracy of above 84%. The results reveal the high
potential of such close range ranging devices for locating and counting grape berries. Thus, the methodology provides practical
support for viticulture applications. |
