Cognex technology ensures high-speed reading and decoding of barcodes and text in the most demanding environments.
A new generation of vision systems has been developed that makes machine vision the preferred inspection technology for wheel fastener inspection. The In-Sight 2000 vision sensor can learn the known good appearance of components and compare many different features to determine if they are pass or fail. The In-Sight 2000 is small, has a fully independent light and lens, and is rugged enough to withstand harsh factory environments.
Using Cognex Deep Learning, it is easy to analyze metal piston weld seams by yourself. Engineers can use the Cognex Deep Learning defect detection tool in supervised mode to train the software on a set of "bad" sample images that represent various welding anomalies (including weld overlap) and a set of "good" sample images that do not have any anomalies. In this way, all anomalies, whether they are required or the main cause of rejection, can be identified as defects. In the second part of the inspection, engineers can use the classification tool to classify weld defects by category. By combining the defect detection tool with the classification tool, automotive manufacturers can ensure that the inspection system identifies all welds and successfully classifies overlapping welds.

Cognex Deep Learning can quickly identify pores under the same lighting conditions, while other methods are still trying to detect them. Engineers can use a set of "good" and "bad" cylinder images to train the software in a few minutes, using the mask filter program to adjust the region of interest and eliminate the bright circular plane with a hollow center. Technicians can use the Cognex Deep Learning defect detection tool in supervised mode to annotate the pores in the "bad" images and adjust the parameters, including feature size, aspect ratio, aspect ratio and shear modulus, to ensure that the created reference model takes into account all appearance changes. "Good" images that describe normal cylinders can help the software learn what kind of minor casting anomalies and variations are acceptable. Engineers can retrain the system, adjust parameters and add additional images until the model can summarize the normal appearance of the cylinder and identify abnormal conditions. At runtime, the deep learning-based software can detect each image in milliseconds, depicting features with pores as defects and other features as normal.
