Location Determination for Mobile Inspection Using Weighted Multisource Position Fusion

• 1、The Second Construction Limited Company of China Construction Eighth Engineering Division

Abstract：Positioning errors can cause location mismatches near region boundaries during mobile inspection. Source coordinates are fused using weights derived from reported accuracy and the time since collection; the observation with better reported quality is selected when sources conflict. Error radii are estimated by quality group, and reverse geocoding provides candidate addresses. Boundary constraints require the decision region to lie entirely within the candidate business re-gion after a boundary margin is applied. Threshold optimization determines output conditions under an empirical mismatch rate constraint. In simulations using empirical error radii for boundary checks, fusion increases the correct output share among all requests from 62.59% with a fixed source to 87.36%, with an output mismatch rate of 0.06%. Boundary decisions using quality groups increase this share from 37.60% under a fixed boundary rule to 39.46%. The method in-creases correct location output under the simulated conditions and provides quantitative criteria for location determination from uncertain observations.
