| Popis: | The co-registration of photogrammetric products such as image blocks or point clouds is an essential step before they can be used for subsequent analysis. Usually this is done by using control points. This has some disadvantages such as the need for additional measuring devices and a laborious measuring of the coordinates. In prior works we developed a procedure that enables a marker-less co-registration of an image block with a digital building model. This extended abstract presents our current research as work-progress. For further facilitating and improving this process we identified two tasks. Using videogrammetry as data capturing technique and using an enhanced matching algorithm during the co-registration. This paper summarizes essential steps when making the switch from photogrammetry to videogrammetry and explains the basic principles of the improved matching process. |
