Feature Requests / Re: (Masking) - Ignore mask feature
« on: April 28, 2017, 03:51:40 PM »
That would be great, using the epipolar lines from a point, if it crosses a mask, to ignore the point.
On the other hand, masks are used to remove unwanted things in photos, and might sometimes be used to mask things on certains photos, but not for permanent removal (ie. a car passing by).
Then it'd be a optional thing I guess?

Python and Java API / Re: Process chunk depending on bounding box's size
« on: April 26, 2017, 04:04:16 PM »
For the record, I printed the values of my variables:
And they're all around 1 or 0.8...
Code: [Select]
box_x = chunk.region.size.x
box_y = chunk.region.size.y
box_z = chunk.region.size.zAnd they're all around 1 or 0.8...

Python and Java API / Process chunk depending on bounding box's size
« on: April 26, 2017, 03:41:27 PM »
Hello everyone
I'm currently working on UAV-based models where I process subparts of a global point cloud. Problem is, if the bounding box is too small, I may have issues processing it (DPC, Meshing etc.) because my photo coverage is insufficient.
Since the scene's coverage is constant (one photo every X meters), I determined the minimal surface for the bounding box to have enough photos in it to process things properly : 500 m².
I figured my condition would be something like
(I also loosen the region size until the bounding box is big enough):
How can I get the size in meters?
Any way to make it cleaner?
Thanks in advance.

chunk.region = region

Python and Java API / Re: Exporting shapes in a different coordinate system
« on: April 18, 2017, 05:40:00 PM »
Hello Alexey,
Can I remove layers based on their labels? If so, how?
I'm using keywords in the labels to determine where to export the file. (The same way I use keywords in chunk labels to process different LODs in one batch)

Hello Alexey,
The problem is, I have shapes in multiple chunks, would this work in a for loop doing roughly this:
Additional difficulty (but I found a way around for this one), it musn't loop through all the chunks but only those with some specific keyword in the chunk label.
Wouldn't closing the project reset the progress in the various chunks?
I'm aware of the fact that this is a very specific question, but my aim is to automatize as much of the processing as possible!

Hello Alexey,
Too bad, I'll see if I change the rest of the scripts I wrote to adapt it to 1.3.x to allow me to export automatically all my shapes, or stick to what I have for now and export my shapes the old-fashioned way, aka manually!
As usual, thanks for the great support!

Hello Alexey,
I think this layer grouping is too recent, as I have the following error now:
chunk.exportShapes(path, groups = layer)
TypeError: 'groups' is an invalid keyword argument for this function
Or is it some error in my code?

Hello Alexey,
I don't get the shape group creation part.
Are groups the corresponding layers by default? Or do I have to assign them first to each different ShapeGroup key? If need be, how do I do that?
For example, I made a small test project with two layers I want to export (see below) as two different shape files.
For now, I have the following code:
Thanks

Hello Alexey,
Thanks for your precious help, as usual!
I'm also trying to export my shapes, using chunk.exportShapes as you recommended. My question is, if I have multiple shape layers, will it create one shape file per layer or one merged shape file?
I'd like to keep my shapes separated according to the shape layers, using maybe the shape layer's name to identify them. Is it possible?

I guess I should use something the like of:
Then I'd export my shapes, right?
Code: [Select]
PhotoScan.Shapes.crs.transform(EPSG::4326, EPSG::3948)
PhotoScan.Shapes.crs.updateThen I'd export my shapes, right?

Hello Alexey,
I'm kind of bumping this topic because I haven't figured out how to do it.
A simple piece of code exporting the shape from whatever his coordinate system is (here I believe it's WGS84) into L93/CC48 would do... Could you help me once again ?

Hello Alexey,
After running a few tests with my script on smaller samples as you advised, I fixed the code. The fact that I was saving two different projects while processing messed up the whole thing!
Thanks for the support, as always.
