Thanks Alexey,

I found what I needed.

General / retrieve processing parameters form log file

Hi,

is it possible to see from the log file what parameters were used in the photo alignement?

Thank you.

Hi,

will it be possible in the final version to export undistorted images with more than 3 bands?

Thank you.

General / 16-Bit Vs 8-Bit

« on: March 25, 2014, 01:08:59 PM »

Hi,

I am working with 16-Bit imagery but when I export my orthophoto I see that Photoscan has trasformed it into an 8 bit image.

Does someone knows if Photoscan can work and export 16 bit images?

Thank you.

Hi FLuca,

the problem is that Photoscan still chooses one Master band for alignment and finally the RGB values exported are still referred to that single Master band. Also I work with four bands and it seems that it is possible to extract the values only of three bands (RGB).

Have you been working with four bands imagery?

Thank you,

Stefano

Hi,

I have been trying several settings to extract 3D point clouds in forested areas (mainly conifers) and it seems that I am achieving the best results with high mild settings when generating the dense point cloud. I have also been trying to use ultrahigh setting but I then start to have some RAM issue.

Any comment on your experience with this regard would be great.

Thanks,

Stefano

General / Working with UltraCam multispectral imagery

Hello,

I am working with UltraCam multispectral imagery and I am trying to extract dense pointclouds with color information associated to each point. More specifically I need to export a point cloud with the following values: x,y,z, RED, GREEN, BLUE, NIR.

I have been trying by using .tif images with the four bands and when I export the .las file I check the color information box. Finally I get the pointcloud with x,y,z and for the RGB values I get the same value that corresponds to the value of only one band (master band used for matching).


Does anyone know if it is possible to do that in Photoscan? It would be really useful to have an export of the colored pointcloud.

Thank you very much.

General / Generating 3D point clouds in forested areas

« on: February 10, 2014, 07:23:03 PM »

Hi

I am trying to extract a 3D point-cloud in a forested area from 60%-30% overlap UltraCam images. My purpose is to get an accurate representation of the forest canopy, which means a 3D point-cloud that accounts for the high height variation present in a forest.

I have been producing some dense point-clouds with Photoscan, however it seems that the canopy always comes out smoothed, while I need to be able to reconstruct a model that shows also the tree tops and identify clearly the edges of the forest and the forest gaps.

Does anyone know how these objectives could be achieved? are there some parameters that can optimize my results?

Thanks in advance for the help.
