Thanks Alexey.  That script works well.

Also, I have been learning about ImageMagick.

Here is some advice from experienced people:

"ImageMagick cannot write 4 channels to an RGB image using -combine. The fourth channel would be the alpha channel and it is added by -compose copy_opacity -composite. You can combine 4 channels as CMYK, if you want, but not RGB.

ImageMagick (6) does not write to multi-channel TIFF files right now as far as I know. It will write to multipage TIFF files by simply,

convert image1.tif image2.tif image3.tif image4.tif result.tif

See also ... php#define for -define tiff:alpha=associated|unassociated|unspecified for alpha specification"

Hi Alexey,

All the photos were taken in one flight and added in the same chunk and processed together - I have reprocessed with Generic pre selection only and it is the same result (screenshot attached) .

I used 1.5 metashape and also the cloud processing option if that helps you fault find.

General / CPU for Agisoft, i9700K vs. i9900K?
« Last post by lieti on Today at 12:13:03 AM »
I'm considering to buy new laptop for field processing  (64 GB RAM, GTX 1070,SSD).
I can order laptop with CPU i9700K (3.6Ghz to 4.9Ghz, 12MB Cache, 95W, 8 Cores, 8 Threads),
or with i9900k (3.6Ghz to 5.0Ghz, 16MB Cache, 95W, 8 Cores, 16 Threads).
Price difference is around 120€.
It is worthy to have 2xmore threads and bigger cache? Or it is better to put that money to something else (e.g. another SSD just for photogrammetic data)?
Thanks in advance.

Hello Paulo,

I have had a busy few days! However I got a chance to collect another dataset yesterday. It includes obliques. This seems to have fixed most of the problem, however there is still some error there. The error seems to be just a vertical shift though. I'm not quite sure where this is coming from yet. I will PM you a link to the data for you to take a look at.

The control points are in EPSG: 26734. I just use the Agisoft coordinate calculator to convert the photo locations to this system.

Hello vcc,

I can suggest the following:

After adding all the images from two cameras/flights to the same chunk, please uncheck all the cameras in the Reference pane and start the Align Photos operation using Generic preselection only (uncheck Reference preselection option).

Hello Apavlicek,

You can find the processing parameters for the main processing stages in the Chunk Info dialog of PhotoScan window.

If you have only export results and no source PhotoScan project data, then you wouldn't be able to get the information about the processing parameters (apart from the coordinate system and export resolution).

Hello nlombardo896,

BSOD indicates that there are hardware or driver issues, have you checked if there's any address mentioned on it?

You can send the log to or share the link to the file put to some file sharing service.
