Latest Standards for Noise Detection of Distribution Boxes
The measurement and process industries are experiencing a significant evolution in standards, with two key publications—IEC 61326-2-7:2025 and ISO 15664:2025—released in December 2025. These advancements bolster compliance and best practices across process automation equipment and open plant noise. Large-scale well-annotated datasets are of great importance for training an effective object detec-tor. However, obtaining accurate bounding box an-notations is laborious and demanding. Unfortu-nately, the resultant noisy bounding boxes could cause corrupt supervision signals and thus dimin-ish. Larson Davis offers a range of advanced noise monitoring solutions that help address these noise challenges efficiently and effectively.
