General / Re: I have an intel NUC iCore 8 using Iris Intel Video
« on: April 01, 2019, 05:22:40 PM »
Alexey,


I am running ubuntu 18.04.

What tool do I need to run to detect the presence and support of the GPU by agisoft

Thanks,
Patrick

Alexey,
I do not see any GPU in the Metashape Preference window.

General / how is the scale bar used on the image
« on: April 01, 2019, 04:23:22 PM »
Hello,

Can some one explain how the scale value is used when you have laid out 8 scale bars in the image?

Is the scale average applied as one number or only a local value?

Pat,

Hello,
How do I enable the GPU on an Intel NUC 8 ?
Thanks,

General / Re: how come reuse depth map is always greyed out
« on: March 19, 2019, 06:48:19 PM »
Alexey,

Can you reuse the depth map if the back ground scene has changed but none of the cameras have moved?
Thanks,
Patrick

General / Re: what do the red and blue marks mean for lens calibration
« on: March 19, 2019, 06:46:32 PM »
Alexey,

Just so I understand correctly the Blue and Red marks indicate where the corners of the checker box would go if the lens correction coefficients are applied.

Is my statement above correct?
Thanks,
Patrick Brown

General / what do the red and blue marks mean for lens calibration

Hello,
I have run the agisoft lens calibration with the supplied agisoft checker board.
What does the red and blue marks mean on each of the camera checker box picture after lens calibration?
How can I see the affect of the lens calibration on the checker board images?
Thanks,
Patrick,

General / how come reuse depth map is always greyed out
« on: March 15, 2019, 09:07:43 PM »
Hello
What is the sequence in processing in the gui to enable reuse depth map.
Currently the option is greyed out.
I am using metashape 1.5

General / depth maps used from sparse cloud to create dense cloud
« on: March 15, 2019, 12:22:25 AM »
Hello,

I am aligning to one set of pictures.

I then perform a change path for a different set of pictures that have the same name.

How are the depth maps used in this case.

hello,

How do I change path to a currently loaded camera images?
I can see the feature in the GUI but I cannot find the equivalient in the Python Agisoft api.
I would appreciate some help on this.
Thanks,
Patrick

Alexey,
What command would that be in agisoft gui console and python scripting?
Thanks,

Hello,
Is the following runstream possible:


1 - align current pictures

2 - optimize cameras

3 - change pictures

4 - produce point cloud

Thanks,
Patrick

General / why is their very little filering in dense point cloud
« on: March 08, 2019, 01:41:49 AM »
Hello,
How come their is very little filtering in the dense point cloud generation?
The sparse point cloud has a series of filter such as minimum number of cameras per tie point.

Why would not also have these same filters in the dense point cloud generation?

General / understanding sparse point cloud and dense point cloud
« on: March 06, 2019, 12:27:15 AM »
In agisoft you:
1- Load you picture
2- align picture ( result is a sparse point cloud
3- then generate a dense point cloud
Does agisoft use the sparse point cloud from align to generate the dense point cloud?
If I filter the sparse point cloud does affect the dense point cloud?
How does agisoft go from a few points in the sparse point cloud to the dense cloud ? Does the software interpolate the data?
Thanks,
Pat,

1-
I see the code:
chunk = Metashape.app.document.chunk
threshold = 2
f = Metashape.PointCloud.Filter()
f.init(chunk, criterion = Metashape.PointCloud.Filter.ImageCount)
f.selectPoints(threshold)
#f.removePoints(threshold)

What does f.removePoints(threshold) do ? Do I need the line to actually remove the points?

2-
I want to add an additional criterion

threshold = 2
f = Metashape.PointCloud.Filter()
f.init(chunk, criterion = Metashape.PointCloud.Filter.ImageCount)
f.selectPoints(threshold)
f.removePoints(threshold)

f1 = Metashape.PointCloud.Filter()
f1.init(chunk, PhotoScan.PointCloud.Filter.ReconstructionUncertainty)
f1.selectPoints(10.1)
f1.removePoints(10.1)


f2 = Metashape.PointCloud.Filter()
f2.init(chunk, PhotoScan.PointCloud.Filter.ReprojectionError)
f2.selectPoints(0.5)
f2.removePoints(0.5)


f3 = Metashape.PointCloud.Filter()
f3.init(chunk, PhotoScan.PointCloud.Filter.ProjectionAccuracy)
f3.selectPoints(8.0)
f3.removePoints(8.0)

Would the above apply the four filters to the point cloud data?
Can you please correct where things are wrong?

Thanks,
Patrick
