• 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…

  • 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…

  • What is the best practice for assigning control for achieving the most accurate photogrammetry?

    Hi everyone, I have a question regarding control points and how many photos to assign control too. I know the minimum is 3 photos for 3 different control points. I am processing photogrammetry for utility excavations and need the photogrammetry to…

  • What size do April Tags need to be?

    I created a project. I went to Tools and saw that April tags need to be at least 35x35 pixels. If I am flying a job with a Phantom 4 RTK at an altitude of 71m AGL that gives me a GSD if 1.95 cm/px If we calculate that out to 35px by 35px that gives us…

  • 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…

  • Data required for Context Capture

    I am using high definition RGB oblique and nadir imagery without GPS or roll/pitch/yaw data. Will context capture successfully stitch imagery to form the mosaic mesh model? We aren't using LiDAR due to a lack of geographic relief for this particular problem…

  • ContextCapture 3SM concave elevations

    I used a DJI Inspire 2 w/X4S camera to obtain nadir and 45 deg oblique imagery in both directions for the use of reality modeling in ContextCapture. Extensive ground control was placed and recorded to constrain the model. After running a quality check…
