• Abstract: Crop yield estimation is a relevant problem in agriculture, because an accurate crop yield estimate can support farmers' decisions on harvesting or precision intervention. Robots can help to automate this process. To do so, they need to be able to perceive the surrounding environment to identify target objects. In this paper, we introduce a novel approach to address the problem of hierarchical panoptic segmentation of apple orchards on 3D data from different sensors. Our approach is able to simultaneously provide semantic segmentation, instance segmentation of trunks and fruits, and instance segmentation of plants (a single trunk with its fruits). This allows us to identify relevant information such as individual plants, fruits, and trunks, and capture the relationship among them, such as precisely estimate the number of fruits associated to each tree in an orchard. Additionally, to efficiently evaluate our approach for hierarchical panoptic segmentation, we provide a dataset designed specifically for this task. Our dataset is recorded in Bonn in a real apple orchard with a variety of sensors, spanning from a terrestrial laser scanner to a RGB-D camera mounted on different robotic platforms. The experiments show that our approach surpasses state-of-the-art approaches in 3D panoptic segmentation in the agricultural domain, while also providing full hierarchical panoptic segmentation. Our dataset has been made publicly available at https://www.ipb.uni-bonn.de/data/hops/. We will provide the open-source implementation of our approach and public competiton for hierarchical panoptic segmentation on the hidden test sets upon paper acceptance.

  Instance segmentation is of great importance for many biological applications, such as study of neural cell interactions, plant phenotyping, and quantitatively measuring how cells react to drug treatment. Box-based instance segmentation methods capture objects via bounding boxes and then perform individual segmentation within each bounding box region. Our method first detects the center points of the objects, from which the bounding box parameters are then predicted. The segmentation branch reuses the object features as guidance to separate target object from the neighboring ones within the same bounding box region.
