Abstract
In quality analysis, optimization design and blunder detection of many photogrammetric problems, repeated computation of reliability matrix QvvP is often required. In this paper, a new recursive method for repeated computation of QvvP is developed. From a test on a bundle block adjustment, it is shown that this new method posesses much higher computational efficiency than the conventional methods.
