Does anyone know how to apply the new/updated normal mapping function in 1.7.0?
Thanks!

Hello!
Anyone know where is the normal mapping feature option in metashape 1.7?
Thanks!

Hello zzha367,

Normal map generation is possible, if you have at least two polygonal models in the same chunk. Please see the related tutorial:

thank you for your reply. Attached you find a log file with the mentioned problem.

I usually work with .dng files, converted from Nikon D850 .nef Raw files - so a resolution of 8256x5504 pixels and a bit depth of 14bit.

Hello Andreas,

In the 1.7.1 update there will be a tweak allowing to downscale images to 8-bit for the depth maps generation, which will considerably reduce the memory consumption. I think it wouldn't affect the resulting quality in general case.

Thanks for this information Alexey. I just tested with a set of 55 Nikon D850 raw images and had the same problem with the updated 1.71 version. The GTX 1660 Ti with 6GB of VRAM ist ignored. Could you please provide the mentioned tweak to reduce the images to 8 bit for DM creation?

thanks again,
Andreas

Hello Andreas,

Please create the following tweak via Advanced Preferences tab:
BuildDepthMaps/pm_convert_16u_to_8u and set its value to True.

Alexey,

The 1.7 user manual incorrectly states that Interpolation is only available when reconstructing from a Dense Cloud:
Quote
Interpolation (for point cloud source options only)

Btw https://www.agisoft.com/forum/index.php?topic=12653.msg57463#msg57463 is still present i, 1.7.1

Thanks Alexey, this seems to work - both my GPU's are now used again.

best whishes, Andreas

1.7 really does haves serious issues with floating geometry inside & outside meshes and other anomalies on the edges.

Hello Mak,

Do you see the improvement of the result, if Moderate or Aggressive depth filtering option is used for depth maps based mesh generation? (filtering can be selected now in Build Mesh dialog).

Alexey,
Not much difference unfortunately. You should try it with your Banana project to easily reproduce it.

Cheers

Now check out the tip of the Banana which is always incorrectly reconstructed in 1.7.x:

Disabled:



Mild:



Moderate:



Agressive:

i understand that new depth maps generation method produces better detailed models than previously.

However for drone aerial mapping, the depth maps generation time is dramatically higher than v1.6 in case of lower end GPU Geforce GTX 670MX as previously reported. Also dense cloud  quality is lower as shown in attached screen copy showing 2 clouds (1.6 and 1.7) side by side with a  lot of noise in 1.7.

Comparing the accuracy of both clouds shows that they are quite consistent except for the noise. In 2nd attachment, the 1.7 cloud is colored by elevation...

As things stand I would continue using v1.6 for dense cloud and subsequent product generation. I hope this issue can be addressed.

Hello Paul,

Have you tried Aggressive filtering in the 1.7.1 release version?

Hello Alexey,

yes the latest version 1.7.1 with agresive filtering produces much better dense clouds but of course with  longer depth maps processing time compared to 1.6 (using Nvdia Geforce GTX 670MX) as was previously stated. Good work on filtering! See attached screen comparing 2 versions...

Hello Mak,

The information regarding interpolation and depth filtering should be corrected now in the latest PDF version of Manual.

As for the banana example, in Aggressive mode I am not observing flying mesh components around the main model, although some areas which are poorly covered have small holes.

Alexey,

Strange. all I did was open the project orignal project and generate the mesh (only changing the filtering modes). We should be getting exactly the same result (unless there's different between OpenCL/CUDA path ?).  Beside the flying mesh component are you seeing the same badly reconstructed tip of the banana?
