Title:
DISTANCE AND DIRECTION RELATION UNCERTAINTY MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/159420
Kind Code:
A1
Abstract:
The present invention provides a measurement method for measuring distance and direction relationship information uncertainty caused by point position information uncertainty. The present invention comprises: a method for measuring distance and direction relationship uncertainty between a point of certainty and an uncertain point or between two uncertain points when the actual position of the uncertain point obeys, within an error circle/error ball/error hypersphere centred on an observation position of the uncertain point, a distribution delineated by a function taking the position as an independent variable. The present invention discloses a function relationship of transmission of point position information uncertainty to distance and direction information uncertainty caused by point position information uncertainty, provides more scientific, reasonable, practical and efficient measurement indexes for geographic space data consistency verification and control, and provides a more solid theoretical basis and more robust technical support for designing solutions of various problems in the related fields of land resource management and law enforcement, surface change detection and urban and rural planning and the like.
