Agisoft PhotoScan 1.4.0 pre-release

[Alexey Pasumansky]

Hello cdoughty,

I suggest to update to the build 5432, as there were some fixes related to the multispectral image processing.

The meta-information related to the irradiance sensor data should be taken into consideration during the orthomosaic generation process, if "Normalize Band Sensitivity" option is checked on in the Tools Menu -> Camera Calibration dialog -> Bands tab (for each band). The option is automatically checked on if the Reflectance Calibration procedure is completed.

Note that latest build that I am referring to allows to detect the images with the calibration panel and mask them out automatically, so you can go to the Tools Menu -> Calibrate Reflectance dialog right after adding source images and calibration images to the same chunk.

Is it possible to install this pre-release version alongside 1.3.*?

If so, how?

Edit: Going back through this thread, seems you just have to re-name your editing PhotoScan directory before installing.

install 1.3 version first, then move the folder to another location, then install 1.4 to default location.

Could you please explain what the “refine mesh” command is doing?
Ie: how is it exactly changing the mesh?

Hello obw,

In which coordinate system in referenced current chunk and which one is used for the point cloud that is being imported?

Alexey,

In my last attempt I tried to set the chunk to the same Reference seting as the scan (.laz file) is: WGS84_UTM11N

This is the last errors, still did not work, see below and Attached images:

2017-11-29 15:08:04 unknown LASitem type 7

Hello obw,

The fix will be included in the next 1.4.0 update.

It seems that for some reason the provided LAZ file doesn't contain the information regarding the coordinate system.

Now it would be possible to select the coordinate system in the Import Points dialog (in case the chunk is georeferenced).

Hello ruyi7952,

Can you provide the full log related to the operation and specify the type format of the input data (number of channels and bit depth)?

Dear Alexey,

This issue never happen before, i mad a project with different chunks (build spares/Dens) and while i put a marker it took all the rams i had (see snapshot) then the sw crash is it normal, its never happen before??

Edit it took most of my Rams while i put the first Marker only, So i disable Refine marker based image content and it works well.

Best

Hi Dmitry,
Release 1.4 looks great!  The new "Import Points" feature has allowed me to test a workflow where I take a point cloud out of Photoscan into CloudCompare which provides great features for editing point clouds (I am working on underwater models which can get quite "noisy" and require some manual editing), and then import the clean point cloud back into PS in order to mesh and texture.
However, one particular model I am working on ended up with a chunk of points missing when I did the import, and this was the case for both PLY and LAS file formats.
Attached you can see the point cloud imported with the missing chunk (empty piece in the middle), and also shown in cloud compare completely whole
I'm thinking this could be a software issue?
Thanks!

[Alexey Pasumansky]

Hello jinjamu,

It seems that the normals for the points in the middle are inverted. Can you try using Invert Normals option in the Tools menu for the selected points?

Hello Mohammed,

Can you provide the information about the chunk's contents: number of dense cloud points and number of polygons of the mesh model?

Hello Mohammed,

Can you provide the information about the chunk's contents: number of dense cloud points and number of polygons of the mesh model?

Thanks Alexey for ur answer,
So the Dens PC a pprox. 2-3 Million and the same for mesh, so while i disable the Refine markerin advance menu and open photo then put marker the sw work fine but while i enable this option and open photo then put marker it took all my rams. (it happen when i open photo then put marker).
look at the snapshot it explain eveything.

Hi Alexey,
Indeed you are correct!
Is there an easy way to select the points that need inversion?  Manually is not so easy.
Is this something that will be corrected in future releases?
Regards
John

Dear Alexey,

Can you figure out a solution to that problem!! i answer above about the problem issue.
