Abstract
En 中文
• A heterogeneous network measurement (HMN) model is established for integrated measurement field (IMF), with instrument observations as input and instrument orientation parameters and target points coordinates as output. • Multiple evaluation indicators focusing on both the structural stability and measurement accuracy are developed based on the HMN model. A stability evaluation method of the IMF is proposed, using the generalized condition number as an indicator. A series of evaluation indicators that encompass instrument observation uncertainty, target points coordinates uncertainty and instrument orientation parameters uncertainty are proposed for comprehensively evaluate the accuracy performance of the IMF. • A visualization method for target points coordinates uncertainty is introduced, utilizing uncertainty ellipsoids by uncertainty analysis based on the GUM method and the coordinate covariance matrix.
