Abstract:The geometry and calibration of three-dimensional multi-beam laser scanning (MBLS) are more difficult than the single-beam laser scanning, especially for one laser emitter and multiple laser-echo detection within the same optical path and scanning with a two-axis-mirror. This paper focuses on the influence of the main systematic errors for the geometric imagery of the MBLS, and presents a plane-based self-calibration to improve the geometric positioning. First, the model of geometric imaging and systematic err… Show more
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.
