<p>Yes you can take non-nadir pictures. You can also take both to
get better overhangs in the textured mesh. ODM will merge them
together.</p>
<p>For the resolution, increase the --orthophoto-resolution
parameter to something like 60 for a better orthophoto. I think
the textured mesh already uses the highest resolution available,
but perhaps try to increase the --

resize-to parameter, maybe that will help?</p>

<p>Thanks, Piero. That explains all. FTR setting that to 4
worked for me and didn't hang up. Admittedly I'm only use four
cores so any SMP race conditions/deadlocks etc are much less
likely to affect me than someone running on 64 cores.</p>
<p>Very impressive results, 82 photos taken at 3m intervals, 30m
altitude using a Phantom 3 Advanced.</p>
<p>Out of curiosity: If I take photos with non-vertical
orientation, e.g. pointing the camera sideways or at an angle,
can ODM automatically integrate the results and avoid the voids
under overhangs?</p>
<p>I'm so impressed with this software and thank the developers
for it. If I had one wish it would be to get slightly higher
resolution results. Some of the detail from the original photos
is lost in the textured mesh. Is this a tunable parameter or a
limitation of the current implementation?<br>

<p>Hi Stuart,</p>
<p>You can use more cores by setting the "opensfm-processes"
option. By default we've set it at 1 because a fault is
causing the program to get stuck sometimes with more cores: <a

<p>Increasing the number of cores at compilation does not
influence runtime behavior, it just compiles faster :)<br>

<br>
I'm running a new install of ODM in a VirtualBox Ubuntu guest
VM on Windows. The guest VM has four cores but ODM only seems
to use one core. <br>
<br>
Looking at some other posts people seem to be talking about
using massive numbers of cores so I feel like I must be doing
something wrong. <br>
<br>
Possibly relevant information: <br>
- ODM was originally compiled with only one core in the VM. I
later increased the number of cores. <br>
- I'm measuring it using one core by monitoring with 'top' and
pressing '1' to reveal individual CPU cores. At all steps so
far (currently up to Computing depthmap for...) it seems to
flatline one core but the others are nearly idle. <br>
<br>
Does it deduce the number of cores at point of compilation?
Do I need to enable something to allow multi-core support?
Are the steps I've observed so far all single-threaded? <br>
<br>
Thanks for a wonderful piece of software! <br>
<br>
Stuart <br>
