Detection and Identification of Overlapping Cards using Terahertz Imaging

Recent advancements in sub terahertz technology have generated significant interest in sensing and imaging and sensing applications within the 300 GHz band. This paper focuses on the detection and identification of overlapping cards utilized in competitive trading card games. We propose a novel method for identifying the overlapping cards through the use of sub terahertz waves. Specifically, electromagnetic waves are emitted toward the overlapping cards with identifiers. By employing the correlation coefficient between the obtained electromagnetic field distribution and a pre-analyzed dataset, the proposed method estimates both of the position and height of the overlapping cards.
