General / How to color dense cloud by reflectance?

« Last post by luckycharms on August 12, 2019, 11:45:58 PM »

Hi all,

I'm using Metashape 1.5 Pro with a Micasense Rededge-M to build point clouds and orthomosaics.  I want to have these point clouds and orthomosaics to be colored by reflectance, not just "color" (i.e. radiance).  Is there some way to do this?  Or, is there a way to verify that the colors are indeed reflectance and not radiance, if that is supposed to be what is produced?

Thanks!

General / Orthophoto of human crania

« Last post by nanxxx7 on August 12, 2019, 04:11:14 PM »

Hi all,

I'm relatively new to Agisoft, and I am using Photoscan Professionla 1.4.5 to create 3D models of human crania, which I have photographed on a turntable roughly every 5Degrees in front of a white background with a standard DSLR. The resulting modes come out brilliantly, yet I am trying to create orthophotos of the frontal view of the model, to have undistorted 2D images of the skulls. Yet the generated orthophotos come out distorted, with their width being larger than their height, where as it should be the other way around. Any help or suggestions is highly welcome!

Many thanks and kind regards
Nina

General / Re: Alignment Workflow - Issues

Hello Resourceful,

The reason of the not aligned images is usually related to the lack of the image overlap. In case of low altitude flights over the dense vegetation and high trees, the excessive overlap should be provided.

Hello Javier,

The accuracy settings defined individually for the cameras/markers in the Reference pane have priority over the default settings set up in Reference pane settings dialog.

So if you have the accuracy values loaded to the Reference pane - they will be used during the optimization.

Have you made any progress, be interested to hear if you came up with a solution? I'm experiencing similar issues.

Cheers!

General / DJI P4 RTK optimization

« Last post by xabierr on August 12, 2019, 04:28:11 AM »

Hi there,

Is optimization using the imported camera accuracy (for example from the P4 RTK's XMP) or is it using the measurement accuracy defined in the reference settings?

cheers,

Javier

Python Scripting / Re: Reading Mesh UV Stats from Python

« Last post by wojtek on August 11, 2019, 04:30:30 PM »

Should I make a better case for this or is this something that you already acknowledge and no further sales pitch is needed?

I can provide examples of how much the fill ratio differs based purely on slightly different mesh (ie, decimated down by 1 triangle)

Hello Alexy
Thanks for quick reply, unfortunately it doesn't work, or it does but with a very low quality when I run the latest script.
to avoid some mistakes, I'll make again align photos, maybe the problem is due to a missing path for depth_maps.
I'll update you as soon as possible.

General / Re: Can photoscan & Metashape work with stills from 4K camcorder slowly panned ?

« Last post by BKing on August 10, 2019, 07:45:14 PM »

Hi,
as I was panning slowly as my 4K camcorder seems to give jerky video on normal panning despite trying the fastest card and best settings, and its £1400 and full manual control, every 10th frame would give far too many images.
I am interested to know, if a subject is 2 meter long, and I am standing 2 metres away, how many seconds panning from start to finish might one need to do to get a suitable number of frames if every 10th frame is used. I was taking maybe 16 seconds to do so. I later did a faster scan maybe 8 secs as another test.

I would have to on this occasion manually edit out the backgrounds on some of the frames in photoshop, as it goes from a shot of the subject and a lot of background in the museum when starting the scan to just the subject.

Hi Steve!

The longer the exposure time the slower you have to pan/move the camera to avoid motion blured pictures.

You don't need to edit out backgrounds. You can use the masking feature in metashape.
