This article presents the sequence of triangulation networks adjustments by search method of non-linear programming, one of them has the horizontal distances measured and the other network has the correlated horizontal angles measured. Similar results of the both methods for triangulation networks adjustments refute an opinion that search method is impossible for correlated measurements adjustments.
This article describes the inertial measuring device IMU, as well as its use in airborne laser scanning and digital aerial photography. This device is used during the operation of a scanning unit and an aerial photo camera. The structure of an additional connection for a digital video camera is proposed, which will record video together with the GPS and IMU data stream. Also, conclusions are given about the quality of output data that affect a final product in engineering surveys.
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.
