For example, HALCON’s anomaly detection allows deep-learning-based inspection tasks to be implemented more efficiently, since only a few images of defect-free objects are required to train the deep learning network. The technology is then able to unerringly and independently localize deviations, i.e., defects of any type, on subsequent images. This means, defects of varying appearance can be detected without any previous knowledge or any labeling efforts in advance.
In addition, HALCON’s new generic box finder is able to determine the exact position and size of arbitrary boxes within 3D point clouds. Thus, it is no longer necessary to train a model for every box size. This greatly simplifies the development and support of applications commonly used by the logistics and pharmaceutical industries.
Reading data codes up to three times faster
Another innovation is that reading of ECC-200 data codes has been significantly accelerated for multi-core systems. The biggest improvement was achieved for codes that are particularly hard to detect and read. Reading is up to three times faster, which also increases viability on embedded systems.
Another new development in HALCON 19.11 is the ability to import deep learning models in ONNX (Open Neural Network Exchange) format. This allows developers to use an even broader range of deep learning networks within HALCON. In addition, the MVTec experts have added a new model for line scan cameras with telecentric lenses to HALCON.
New machine vision features available within a short period of time
"With HALCON 19.11, the latest release of the HALCON Progress Edition, we will offer many new and improved machine vision features within a period of only six months. We have emphasized the further integration of groundbreaking deep learning functions. In addition, we have greatly improved our tried-and-tested core technologies, for example for reading data codes or for 3D machine vision," explains Johannes Hiltner, product manager HALCON at MVTec.
As of late, MVTec provides its own Deep Learning Tool to ideally prepare image data for training neural networks with HALCON (www.mvtec.com/products/deep-learning-tool).
