Paper Abstract

Automated fiber placement (AFP) is an advanced manufacturing technology that has led to an increased rate of production in composite materials. At the same time, the need for adaptable and fast inline control methods increases. Existing inspection systems make use of handcrafted filter chains and feature detectors tuned for a specific measurement method by domain experts. These methods hardly scale to new defects or different measurement devices. In this paper, we propose to formulate AFP defect detection as an image segmentation problem that can be solved in an end-to-end fashion using artificially generated training data. We employ a probabilistic graphical model to generate training images and annotations. We then train a deep neural network using a recent architecture designed for image segmentation. This leads to an appealing method that scales well with new defect types and measurement devices and requires little real world data for training.
