Agisoft Metashape 1.6.0 pre-release

[Alexey Pasumansky]

Hello BjFaeTorphins,

Have you added new images to the chunk before re-starting the alignment operation?

If you are to use Estimated Preselection in order to find new matching points between the images that have not been matched, you should also enable "Reset Current Alignment" option.

Alexey,

Added GPU-based texture generation support for AMD GPUs

Which drivers should be used ? Because it doesn't seem to work (everything is done on the CPU still) on the latest 19.9.2 WHQL drivers or the latest 19.11.1.

Cheers

Hello Mak,

Which OS and GPU model you are using?

Hello Mak,

Are there any GPU-related lines in the log?

Currently there are some limitations:
 - no masked photos should be present,
 - only 8-bit images on input,
 - no ghosting filter applied.

[Mak11]

Alexey,

I had ghosting filter enabled..Now it does work when it's turned OFF (those limitations should be added in the change log IMO).

GPU blending is up to 8X faster based on the short test I did which is insane! 😮

Once those limitations are lifted it will be pretty awesome. (Ghosting Filter and masking are super important to me)

CPU (Ghosting Filter On)



GPU (Ghosting Filter Off)

The new point cloud confidence option is very useful for filtering noise and simplifying classifying.


Out-of-core is excellent too! 

Thanks Agisoft!

With build 9487 I'm getting:

Assertion 239107090 failed at line 7122!

when trying to construct the mesh from depth maps. This occurs both on Ultra and High quality settings.

I attach the log file.

Hi cbnewham
Try to update your nvidia GPU with latest driver, my config show 10020/8000

Hello cbnewham,

This issue will be fixed in the next version update.

Could you please provide more information on the additional calibration coefficients?  What additional coefficients are used compared to the standard Brown model and how are the equations different?

Thank you

I am curious to know what Fit additional corrections option do in Optimize Cameras dialog?....

What are these corrections and when should we use this option?

Hello Paulo,

Fit additional corrections option enables additional calibration coefficients that allows a better fit of the lens distortion model. This is especially important for wide angle lens with large radial distortions, e.g. DJI Phantom 4 RTK camera.

This option is mainly intended to be used in cases when highly accurate reference data is available (RTK/PPK) and it can help to achieve higher accuracy when no GCPs are available.

How to interpret confidence range?
The color scale bar for confidence goes from 1 to 100, but the Select Confidence Range has a Min of 0 and a Max of 255. Also the color legend goes from 1 to 5, 5 to 10, and then makes a jump from 10 to 100.

[Alexey Pasumansky]

Hello bisenberger,

The legend shows non-linear scale, since the most of confidence variations that are of interest are observed on 1-5 range. On the legend 255 number is pretty close to 100, actually.

Thanks Alexey,
Filtering out 1 to 5 makes a big difference in the quality of the point cloud.
