The Swiss Gemmological Institute SSEF is introducing to the market a new system for scanning both single and multi-strand pearl necklaces. Called PearlScan, it is able to count large quantities of pearls on strands, and measure their dimensions. Consisting of an A4 scanner, computer and proprietary software, the system offers the pearl industry a new and efficient way of documenting pearl necklaces.
Developed in collaboration with CSEM (Swiss Centre for Electronics and Microtechnology) and supported by a prestigious CTI grant from Switzerland's Commission for Technology and Innovation, PearlScan provides its users with effective and easy solution for counting and measuring large quantities of pearls on strands in relatively short periods of time.
The PearlScan software incorporates a complex algorithm that enables the detection of different strands, and a count of the pearls while measuring the diameter of each one and distinguishing them from other elements (such as knots, diamonds and other decorative items). It also calculates a roundness factor for every pearl, and measures the length of each strand. Semi-automated, the system welcomes user intervention to optimise and review output. In terms of documentation it produces images and a detailed reports of the number and diameter of each pearl on the different strands.
PearlScan was developed to pursue SSEF's mission of developing niche technology for the trade and supporting the pearl industry. "We have found that PearlScan greatly supports analytical and documentation procedures in our own laboratory at SSEF. We are glad to be able to offer now this new and easy-to-use solution to the trade and pearl industry," stated SSEF Director Dr. Michael S. Krzemnicki.
