Bundle Adjustment Methods in Engineering Photogrammetry

Abstract: The bundle method is a flexible analytical tool for co‐ordinating engineering and industrial structures. This paper investigates, mainly from a theoretical standpoint, what object space control, if any, need be incorporated in a bundle adjustment and it promotes the use of multistation photography for such projects. The concepts of inner accuracy and free network adjustments are introduced as being valuable in comparative precision studies. Self calibration techniques for the compensation of systematic errors,… Show more

“…The rank deficiency of the Least Squares problem can also be removed with an inner constraint. This does not involve external observations and leads to the so-called free-net solution (Granshaw, 1980;Dermanis, 1994). The theoretical accuracy obtainable with a free-net adjustment, coupled with precise image points and good calibration parameters is superior to 1:100,000.…”

“…Three-image matching is much more discriminant than two-image matching, so there should be fewer outliers in a RANSAC run. Also, it is well known in photogrammetry that a triangle of three widely spaced cameras gives much stabler and more reliable geometry estimates than classical two image stereo, essentially because errors within epipolar planes are uncontrollable under stereo [11]. The paper is organized as follows.…”

“…This control information can be in the form of a 2D or 3D test field which includes several signalized targets, whose coordinates are either determined from a pre-surveying process or estimated using a free-network adjustment procedure (Granshaw, 1980). Depending on the nature of the utilized test field, convergent images and images in portrait and landscape mode might be required to avoid dependencies between the IOPs and EOPs during the bundle adjustment with selfcalibration procedure.…”
