This paper describes a non-invasive. automatic. and robust method for calibrating a scalable RGB-D sensor network based on retroreflective ArUco markers and the iterative closest point (ICP) scheme. We demonstrate the system by calibrating a sensor network comprised of six sensor nodes positioned in a relatively large industrial robot cell with an approximate size of 10   m &#215... https://lockdownsecuritycanada.shop/product-category/smart-mirror-lcd-display/
