General / Building Mesh from Depth Maps became TOO slow! Why?
« on: March 28, 2020, 04:01:03 AM »
Hi everyone,

I've encountered a very strange problem. I have a bunch of chunks that are all relatively identical to each other (120 photos) of a model sitting down posing difference facial expressions.

I have previously processed the chunks in relative time, meshes taking 1-1.5H (still think that's a bit long) however when I went back to re-build the first chunk, it was to my enormous surprise that the progress bar stayed stuck at 74% for around 20-30mins before it added more processing time which I can see from the log started typing away, resulting 3 hours!

I have been trying different things rebuilding it (also doing it through scripts) even though I've changed nothing to begin with! I've even disabled CPU processing just to see if it can rely on my GPUs (I have two RX 580 8GB cards).

I've tried another chunk which took a little bit longer than its original but nowhere near as this one.

This doesn't make sense at all, why has this Metashape (1.6.1.) decide to bring down the performance to a grinding halt??? :(

Anyone?

I'm pretty sure it can.

I've managed to do it manually by creating Dense Cloud and cancelling the operation once I see the Depth Map is stored in the chunk.

Also is there a shutdown script that can be applied after the processing has been completed?

Thanks for that.

Would this script also work for Photoscan 1.3.5.?

Thanks.

Will this affect all chunks, including those that have been "disabled"?

Okay, it seems to be working at the moment.

How do I process Depth Maps for all the chunks in the project?

Now I've left it running and Metashape has completed hanged, frozen.

I'm running this script but I'm not seeing the Depth Maps being stored in the chunks :(

I need for it to replicate the setting I usually do in Metashape, that being the quality=Ultra High Quality and Mild Filtering.

I don't understand the parameters of that script, what is downscale? filtermode? max neighbours? subdivide? cameras? workgroup?

I don't recall all of this stuff. I even tried reading the Metashape Python reference and it doesn't exactly explain what it means :(

Thanks very much for that.

What if I want to do it for a bunch of chunks? Or a Batch Process?

Hi,

Does anyone know if there's such a script or an option to process Depth Maps only?

I've already have the option checked to keep the depth maps in the preferences, but I don't want to build meshes straight after, i would rather do each step for a bunch of chunks all in one go.

I'm having the exact same problem as this, except I'm doing it for copying the bounding box. After I execute none of the other chunks bounding box has been altered.

How can i get this to work??? :(

Thanks for your response, all of which has been really helpful!

Before continuing, I've now encountered a new problem. I have been getting this vector<T> too long error when building textures.

I've tried making small changes to the region box but sometimes it still persists! :(

Hi Alexey,

It is a mesh built from the ground up but within version 1.1.4. (the same for Sparse and Dense cloud).

The same UV parametrization was applied from 3ds max (exact same procedure!).

I have opened the project into Metshape and re-built the texture on a separate chunk, and I do get the same result, no stripes.

Okay Alexey, I've done a quick test myself.

I went ahead and hunt down the version I used many years ago, that being Photoscan 1.1.4.

I actually rebuilt everything from the source images with the masks. I have noticed that every step was notably faster than any of the new versions.

Created a texture from newly applied UVs done in 3ds max and voila! Exactly how I remembered it!

No stripes or artifacts.

Nothing was done different.
