General / Re: Mission Planning using DJI M600 & Sony A7R (II)
« on: June 29, 2017, 06:17:20 AM »
What you want to do is possible and being done.  Contact Drones Made Easy.  They sell a triggering package for the M600 for Sony A7R and it works with other Sony mirror less models too.  You can do precise mapping missions with a pro level camera that provides consistent high quality images without the exposure or white balance issues (to name a few) the DJI cameras are plagued with.  It will trigger reliably down to 1 second intervals.  With that speed and large sensor it is possible to cover a lot of area at high resolutions.

General / v1.1.0 tiff format scanlines or tiled
« on: January 30, 2015, 08:28:59 PM »
It appears that in v1.1.0 the export orthophoto feature creates TIF blocks that are in tiled format where the previous versions outputed scanlines or strips organization?  We have a custom program to merge blocks and perform other functions and it is now failing with blocks from v1.1.0.  Is there a parameter or configuration to control the format and go back to scanlines, or do we need to rewrite the program?  Thanks.

General / Re: Mask objects from DEM
« on: January 15, 2015, 03:13:39 AM »
Sorry I should add that "blue rods" is just an metaphor for what is actually small complex features that cannot be masked with any conventional tools in Agisoft.  Think more like tall plants I don't want to see growing in a large landscape!  And there may be thousands of them in the stitched orthophoto.  They have to be masked by algorithm either at the original JPG level prior to Agisoft or in the Orthophoto after stitching.

General / Mask objects from DEM
« on: January 15, 2015, 03:01:13 AM »
I want to exclude from the stitched DEM certain small features of my subject that protrude higher than the rest of the surrounding subject matter.  For example remove a small narrow blue rod sticking up in the middle of a much larger predominantly red scene.  I could do this by mapping pixels between the stitched orthophoto and the dem then generating a new dem based on colors of the features I want to mask out.  However the blue rod is a finer feature than the point cloud density so the point cloud averaged the elevations of other pixels I want to keep that are close to the pixels of the blue rod targeted for removal. So this is ineffective.

The other solution is mask the pixels of the blue rod from each of the overlapping original JPG images prior to stitching.  My question is how to account for the removed pixels in the JPG so that Agisoft will not be confused and ignore them and stitch with only the remaining pixels, and obviously produce an accurate DEM?

Has anyone tried to do this, mask out details this fine?  Thanks!

Python and Java API / Run GDAL in Agisoft Python script
« on: November 15, 2013, 01:09:28 AM »
Hello,

I've written Python code that successfully automates an Agisoft workflow and runs in Agisoft and would like to add a step at the end using gdal_merge after Agisoft exports a blocked orthophoto.  Any tips on how to get GDAL functional from a script running within Agisoft?  Currently I can run gdal_merge from other places like OSGeo4W shell or a windows batch file that I created.  But it would be less steps for users to tack the merge at the end of the script in Agisoft.  Maybe this question is more about how to successfully install GDAL into Agisoft's Python environment.  Has anyone accomplished this?

Thanks!
Kevin
