What is Palentier

Mark Willis’ Palentier

Palentier processes aerial photographs collected from a camera aboard a MikroKopter, or similar Unmanned Aerial System (UAS) then scales, orients and projects the images to real world mapping systems. It does this by analyzing the telemetry data from the UAS and merging it with the aerial photographs. The resulting data is then superimposed for viewing in Google Earth or in a Geographic Information System (GIS) like ArcGIS. Currently, export to Google Earth (KML and KMZ), JPEG world files (*.jpgw), and Leica Photogrammetry Suite’s “initial exterior orientation” file format (.dat) are supported.

    the orthophoto is the easy part, since it can be done in qgis at any point (just takes an extra step). the 3d model is tricky, but doable if you also have one measured distance, since meshlab can scale it for you. I am trying to figure out how to best automate this process, since I am designing a workflow for myself and less experienced personnel. Thank you for your reply, I am learning this as quickly as i can, as I am using it to monitor stream geomorphology and fish habitat. the 3d models will be used to estimate removal and fill volumes on restoration projects, which is why it has to be scaled and hopefully fairly close to reality. any thoughts on vegetation removal from these models would be useful as well.

    I also think that Mission Planner has this functionality built into it. what I am lackign is a way to use this data to orthorectify my visualSFM project so that the cmpmvs output is all orthorectiofied and scaled properly.

      I have not had time to georectify in the open workflow yet but have some ideas. VisualSFM allows the use of GCPs or camera GPS and will apply coordinates to the point cloud. The next steps would be to bring the geo-point cloud into GIS (QGIS specificly) and use the point cloud as control points to georeference the orthoimagery. Of course if you’ve collected GCPs then you can skip all that and bring the ortho straight to QGIS and apply them to the ortho.
      I believe QGIS also provide access to background map imagery such as Google and others so you can always georeference new imagery (ortho) to existing imagery (google/other).

    link is no good, does this project still exist? I am waiting with baited breath for the rest of these tutorials you have promised. the first post processing ones are great, just need to get the georeferencing part to work smoother.
