The UAV-based DSMs have recently been used in agricultural applications, for example to calculate tree/plant area, height, and crown size to assess biomass volume. eCognition offers a unique data fusion approach to use the full information potential of UAV-based elevation and image data.

On a UAV-based dataset provided by University of Sassari - Dipartimento di Agraria, Christian Weise developed a rule set to extract the position, height, and crown volume of vine plants.

Important algorithms used in this project:

• pixel min/max filter (prototype)
• layer arithmetics
• automatic threshold
• watershed segmentation
• convert image objects to vector objects
