The need for zero drift and accurate object pose estimation is very common in today’s industry. Implementing optical measurement system allows to overcome certain problems, that are inherent to inertial navigation systems (INS). These problems include size and weight of high accuracy systems of the type and zero drift, low dynamic range. Method, described in this article is based on the fiducial markers recognition. The markers were located on investigated object, their positions were estimated on four images, captured by four digital cameras, connected to the PC. The Results, obtained by four cameras, were processed by developed algorithm, allowing to conduct pose estimation with an accuracy of 0.2 degrees in 3 degrees of freedom.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
