General / Re: Exporting google kml/kmz

Hello Kjellis,

It is supposed that the user could see textured model in Google Earth if .kml is exported with COLLADA (.dae) model file.

Sample kmz-file: http://downloads.agisoft.ru/photoscan/sample_kmz/Kikins_Chambers.kmz

Hello pixelpusher,

Is FBX the only format that suits your project or there are any alternatives with more open formats?

Hello Kjellis,

Yes, that's it. If you have one-component model there is nothing to filter.

Hello,

Filter threshold is an equivalent of Select Components feature. After the model is built smaller isolated components are filtered automatically if Filter Threshold value differs from "0".

Hello Mike,

Currently we recommend one of the following desktop hardware configurations:

1. The cheaper one:
    CPU: Intel Sandy Bridge 2600 or 2700
    RAM: DDR3-1600, 4 x 4 GB (16 GB total) or 4 x 8 GB (32 GB total)
    GPU: NVidia GeForce GTX 580 (optional)

2. The better one:
    CPU: Intel Sandy Bridge 3930K
    Motherboard: any model with 8 DDR3 slots and at least 1 PCI Express x16 slot (for example, ASUS P9X79 PRO or Gigabyte GA-X79-UD5)
    RAM: DDR3-1600, 8 x 4 GB (32 GB total) or 8 x 8 GB (64 GB total)
    GPU: NVidia GeForce GTX 580 (optional)

Hello Jerry,

Processing time depend both on settings used and system parameters.

You can speed up Align photos stage by using Medium/Low quality or using Generic preselection.
Build geometry stage is more resource demanding process, so the suggestion to lower the quality setting is correct. In low quality you'll get the model quite fast.
Also it is possible to speed up this stage by enabling OpenCL optimization in PhotoScan preferences.

General / Re: Export DEM resolution
« on: January 23, 2012, 05:37:38 PM »
Hello bvpham,

The best DEM resolution is defined by the effective model resolution. Which is determined by quality used for geometry reconstruction. The higher is the quality the more details you'll see in DEM exported.

Usually DEM proposed resolution by PhotoScan is slightly greater than max effective one. But is you set more detailed resolution than it could be acquired using the current model, it would be interpolated.

Hello FoodMan,

Could you please provide a screenshot with one of these seams in render you are using.

« on: January 23, 2012, 03:28:15 PM »
Hello MeHoo,

It is recommended to have the whole object in detail by not only a small area to be focused at. Like FoodMan has already suggested using smaller aperture is better for depth of field increase.
Unwanted background could be masked but sometimes including background improves the alignment (only if the scene is still and object was not moved relative to background).

Now we are implementing feature that shows selected points from Point cloud in photo point view mode and also Filter by markers option in Photo pane. I think it will be in the next 0.8.5 update.

Maybe, it will be more effective if you've got samples of image datasets similar to the object you've got (shot by the same lens with the similar aligning problems). So we could give you more specific recommendations according to the images we'll actually could see and try to process by ourselves.

Hello FoodMan,

Do you see seams only in PhotoScan 3D-view or exported models have visible seams too?

Hello Thomas,

You should use Sharp geometry type setting in Buid geometry dialog and reduce Hole threshold value.

Hello Rob,

And does exported GeoTIFF DEM have negative values with the correct GCP coordinates?

Could you please also export Ground Control values and send them to support@agisoft.ru.

General / Re: Aerial DEM noise removal
« on: January 20, 2012, 03:07:54 PM »
Hello bvpham,

Face count setting in Build Geometry dialog specifies only the terget face count for decimation process performed after the model is build. You can use "0" setting if you want to perform the decimation later.

As for geometry quality parameters I think that 4 Gb would not be enough for processing 170 images in High. But in Medium maybe it could be processed.


And regarding the noise - do you see the noise in point cloud view mode?

Hello John,

PhotoScan allows to import camera positions in bundler format. If you have any suggestions about other popular formats that you wish to be supported by PhotoScan import/export please name them.

PhotoScan exported chan file has the following format:
camera_number x-coord y-coord z-coord euler-x-axis euler-y-axis euler-z-axis v-fov
