Paper Abstract

The handheld target greatly expands the fields of the vision measurement systems. However, it introduces extraction errors and position errors, which degrades the positioning precision of the vision measurement systems. In order to evaluate the influence of the handheld targets on the accuracy of T-VMS, we first analyzed the positioning principle of the visual measurement system and established the precision model under two typical structures of the T-VMS. We then studied the extraction errors and position errors introduced by the handheld targets and quantified the errors. Finally, we discussed the influence of the said errors on the positioning in 3D space with system precision model. We applied the precision model in an actual T-VMS to confirm its feasibility and effectiveness, and found that it indeed estimate the errors introduced by the handheld targets effectively.
