• Best practice and settings when running a photogrammetry project with drone photos including basic GPS data and survey grade GCP:s?

    I've been searching the forum and read all the manuals avalible for Context Capture Master and the process of aerotriangulation and productions of orthophotos. But I'm still uncertain on how the process should be conducted in order to achive best result…

  • Recommended number of control points - control point density

    I'm desperately searching for a page I've recently seen on the forum (or was it the Wiki?), describing the maths and process on how to determine a good distance between GCP;s on a large land survey project. - Is there anyone out there who know what…

  • Surveyed Ground Control measurements and there reuse with a different SRS

    For our ContextCapture projects we have two customers. One customer needs Nad83(2011) NCSP NAVD88 Geoid 18 (xyz units us survey foot), the other customer needs Local Space Rectangular. The difference between the two SRS's is normally a scale factor. Knowing…

  • VLP-16 LIDAR with KAARTA integration into Context Capture

    My school is undergoing a campus modeling project and we only have a cheap VLP-16 LIDAR puck scanner that we have been able to use and process through KAARTA. Because of the minimalistic setup, there is no GPS on the unit and no geographical reference…

  • Why does my focal length change for the same camera in different photogroup?

    I'm using Sony A7R II with 28mm lens and I'm curious why my focal length change slightly? it's a prime lens and manufacturer spec says it's 28mm and the aero-triangulation optimized the focal length in the range of 27.13mm - 27.20mm for different photogroups…

  • Having Problems with Control Point Import

    Hallo! I am having big problems with importing Control Points in ContextCapture via Control Points Editor. Please check my Attached TXT file where I have GCPs from Local Survey team. Software does not want to import them. I have tried several formats…

  • control point ContextCapture

    Hi! I'm testing the accuracy of the photogrammetry process. So I use GCP and check point (CP). When I use only GCP the aerial triangulation's error is not relevant and the result is good but when i use GCP and CP the CP's error is higher than GCP's…

  • Importing Orientation Metadata

    ContextCapture allows you to import all needed information to create a block from an XML or an Excel file (.xls). This is useful in many situations, including the case of aerial projects containing a large amount of photos, when orientation and positioning…
