At GeoBuzz 2024, Geodelta announced a groundbreaking innovation in Omnibase: it is now possible to perform measurements in any oblique dataset thanks to the integrated bundle block adjustment. This advancement makes measuring in oblique imagery not only simpler but also faster and more accessible.
Oblique photos are images taken from an aircraft at an angle, usually in the four cardinal directions. Compared to standard vertical nadir photos, oblique images provide significantly more context and insight into the environment. Municipalities often procure these photos due to their value in public space management.
While measuring in oblique photos was already possible in Omnibase, earlier versions imposed strict requirements on the quality of oblique datasets. Since oblique photos are often intended as visual aids rather than metric products, most datasets are unsuitable for precision measurements.
The latest version of Omnibase addresses this issue. At GeoBuzz 2024 in Den Bosch, Geodelta introduced the integrated bundle block adjustment. This technology accurately determines the positions and orientations of all images in a dataset. The process is conducted using a least-squares adjustment according to the Delft Method, including extensive verification. The result is a metrically high-quality dataset ready for immediate use. Moreover, this computation is entirely cloud-based and includes a comprehensive geometric quality report.
Measuring in oblique photos offers numerous advantages, especially for maintaining the Large-Scale Topography Base Registration (BGT) and the geometric component of the Addresses and Buildings Base Registration (BAG). With a typical precision of 5 cm, this approach can replace traditional surveying methods and stereo mapping.
