General / Performing band alignment for single MicaSense RedEdge images
« on: August 02, 2018, 11:21:34 PM »
Hi, all, apologies if something like this has been asked before.  I'm currently working on a project where we are flying primarily over water, which means I can't generate orthomosaics from our imagery.  I have scripts that project the images onto the surface individually, but I optimally need to align the bands.  Is there a way to do a band alignment on an image in the set and export band-aligned images based on those parameters?  TNTgis has a feature like this, but I would prefer not to buy extra software if PhotoScan can already do something like this!

Thanks much!

Bug Reports / Problem with tiled orthophoto export
« on: March 11, 2014, 01:22:00 AM »
I have some aerial imagery that I've exported to tiled orthophotos before, and had no problems with it.  This time, I've got just enough images to break it into two chunks, and while everything seems to align well, and looks good in the model viewer, when I export the tiles, I get tiles out of place.  Most of them are in the right spot, but random ones aren't.

I ran this on both SLES 11 and Windows.  Running on SLES 11 generates all the tiles, but puts them in the wrong place.  Running the same export on Windows simply skips the misplaced tiles entirely.  (1.0.2 on SLES 11, 1.0.1 on Windows.  I've updated both now to 1.0.3.)

Any ideas what's going on here?  Did I miss a step working with chunks?

Thanks!

General / Problems aligning cameras for multispectral imagery
« on: October 22, 2013, 02:50:21 AM »
Hi, everyone,

I'm a bit new to this whole process, so forgive me if I've overlooked something along the way.  I've got multiple sets of agricultural imagery that I'm trying to get to mosaic.  I'm having little trouble with my visible set, but more trouble with the lower-resolution multispectral data (red, green, NIR).  I'm guessing this has something to do with the fact that the camera  (the Tetracam ADC Lite) doesn't image as quickly, giving me much less overlap.

So what I'm wondering is if there is a way to simply project the imagery onto a flat surface, as opposed to creating a depth field.  I have the orientation of the cameras to a reasonable degree, and the areas I'm flying over are flat enough so as not to really need a lot of depth information.  I'd be okay with just getting georeferenced single images out, and I can work with them from there.

If that doesn't work, is there some way I can tweak the point detection algorithm setting?  It definitely doesn't think my cameras are looking at a flat (or near-flat) surface.

Again, if I'm missing something simple, sorry!  Thanks for the help!
