Automatic bin picking is a major problem in robotics with the goal to pick objects from a bin by a robot arm. The iBinPick project is targeted to study the problem of bin picking for small identical objects, which are piled randomly in large quantities and thus, making the inherent challenges of bin picking more severe. Namely, the objects are more densely crowded and their individual recognition requires more insightful strategies. Moreover, the 6D poses of small instances demand more precision to be grasped by the robot.
Generally, bin picking consists of four main steps, (i) object detection, (ii) 6D pose estimation, (iii) motion planning and (iv) control. In this research, we focus on the first two phases, i.e. object detection and 6D pose estimation, which together establish the computer vision module of the project in order to understand the scene via sensor. We mainly use Microsoft Azure Kinect camera for capturing aligned RGB and depth images. In the experiments, the camera is mounted at two heights of 30 cm and 60 cm above the bin ground.
The real test dataset for object detection module is publicly available.
