A Benchmark for Automated Vickers Hardness Testing
摘要
Automated Vickers hardness measurement methods must be robust and versatile to cope with materials with rough and noisy patterned surfaces. The behaviour of several state-of-the-art algorithms for automated Vickers hardness measurement is evaluated and compared for their respective robustness and accuracy. The evaluation is based on real world industrial data, collected in a Vickers indentation dataset. Addressing the current lack of publicly available (annotated) Vickers indentation data, and in order to provide a benchmark for further investigations and experiments, we release the databases used in this work, together with expert groundtruth covering diagonal measurement and segmentation masks, and make them available on-line for public open access.
