Forum Post: RE: ContextCapture Services in London?
Actually there is need for such web portal(like Bentley geocoordination services) to find for which areas reality models are available. Service providers could mark places which are scanned and provide...

Attaching an XML example from Contextcapture Update 10. Extracted features are under TiePoint and image-to-image matching is Measurement. But it may be that older Contextcapture versions didn't have...

We get 7m difference even when using local geoid so it is more related to CC aerotriangulation issues. Until it is clear why there difference it is best to use GCPs. There is a good paper regarding DJI...

I create models from aerial photos taken from a fixed wing or helicopter. Most of my projects are buildings or small rectangular areas and I normally fly in a circle and shoot overlapping oblique...

Oto, thank you for the white paper. Big help setting all the distortion parameters. But I'm still having difficulty getting my check points even close after aerotriangulation. I know how to survey but...

Hi, I am learning context capture, I produced a beautiful 3d model when viewed in acute 3D viewer, but when I open he DGN file in Microstation, I only show the mesh view, how do I view the model with...

Hello, Please let me add a question. How to add a logo in 3MX model for ContextCapture Viewer, not for Web Viewer? I put the “logo.png” file in 3MX production folder (tried both for web and not for...

Have you tried drone harmony app? It shows optimal routes.

Best is to set GCP locations after as then it will be more close to actual positions. Also do not forget to use aerotriangulation with accurate metadata setting. I think you do all correctly just...

With Contextcapture it won't be easy as Contextcapture or Contextcapture editor doesn't have texture/material editing capabilities. What you could do is produce orthophoto and then edit and drape that...

Thank for the link Oto. I looked at the user manual and it seems this was designed primarily for automated use with drones; i assume the app controls the camera angle etc. I use a more manual method. I...

Thank Oto. Just curious if your photos are geotagged with lat, long and ellipsoidal height? However, my photos were receiving ntrip corrections during the flight. would my photo be geotagged with lat,...

I also tried once by putting 7GCP into my 300m road model. The vertical accuracy changed from 2m to 2cm. FYI However, I think RTK UAV should be readily used while without GCP. Its meant to be an...

I finally figured out that my Phantom NTRIP RTK positions were off by 4m horizontally and vertically from my GCPs. I'm pretty sure it was the NTRIP corrections to the drone. I was using existing...

App shows routes so it is not necessary to use it for automatic flight. You can draw your own shape and check if there is overlap with not only nadir but other plans. Drone Harmony Maybe Bentley could...

What we need is an option to input an known vertical offset in Contextcapture. For example if launch point is inside the area with known altitude then we could use the difference from DJI altitude...

Forgot to mention that by default CC sets it as sea level reference. But I have found out that setting it after adding photos to WGS84 gives more accurate altitude at least for comparing with GCPs,...

Aerial photos are normally captured using automation and can be nadir, oblique or a mixture of both depending on the results you need. Using the settings in the automation (altitude, overlap and speed)...
