This paper investigates fast and inexpensive measurement methods for defect detection in parts produced by Additive Manufacturing (AM) with special focus on lattice parts made of ceramics. By Lithography-based Ceramic Manufacturing, parts were built both without defects and with typical defects ...
Direct layered manufacturing (LM) is an additive manufacturing process where part is built layer by layer based on its CAD file. Indirect LM is a process where mold for a part is built by direct LM process. In this work we demonstrate a machine vision setup for surface voids detection which...
Learn more about the role of digital signature analysis in defect detection and resolution. Explore how our QualityWorX suite of data management and manufacturing analytics software can help your team with defect avoidance and boost the quality of your output. Case study: 7 engines, instead of ...
In this work, two segmentation methods were used, namely the threshold method and the edge detection method. Both images are superimposed following a series of conducted convolutions. This process facilitates the comparison of both images pixel by pixel and the detection of difference whether it is...
4.1.1 Steel manufacturing The steel defect detection method has recently received a lot of attention [92–94]. These approaches aim to find the crack on the metal surface to prevent any fault in the process. Since the available data on the cracks is not enough for training the model, Yun...
manufacturing lines for different products. For instance, Orobix applies defect detection todrug manufacturingwith a specific type of camera that can be used by an untrained human operator. The same principle is applied to inspectingpharmaceutical glassdefects, like cracks and air blobs caught in the...
Now that we have discussed challenges and solutions at the defect level, we will examine the next level of detection classification, the die level. At the die level, there may be multiple defects and anomalies. With that in mind, chip makers looking for defects at the die level can apply ...
for automated quality assurance, product inspection, anomaly detection, and more. Our manufacturing customers have built hundreds of custom computer vision systems with Roboflow, taking what used to be manual processes, automating them in just a few days, and scaling them across thousands of ...

This paper presents a visual inspection system aimed at the automatic detection and classification of bare-PCB manufacturing errors. The interest of this CAE system lies in a twofold approach. On the one hand, we propose a modification of the subtraction method based on reference images that allow...
