I would really like to be able to replace existing photos what whatever I would fell like to replace them with! No exact matches of file names etc! And I would like to do it on selected images and in the standard version. In a batch of course not photo by photo..and I dont want to use a script to do it! Thank you:)

General / Export Depth Maps

« on: May 28, 2014, 03:44:33 PM »

Is it possible to get the depth maps generated and saved in the same way textures are? Also noticed when enabling Keep depth maps in preferences and export depth maps you get options to save out texture, normal map and depth map. Why isnt it possible to get these out the same way as textures? And lastly, what is the main purpose to be able to save them out picture by picture?

General / Here I go again..8bit, 16bit, 32..

« on: May 27, 2014, 10:51:36 AM »

I've asked this question before and try and re read some post about Agisoft handles bit depths.

So when using 16bit tiffs and save out texture as tiff they are converted to 8bit, does that mean that my 16bit tiffs are converted to 8bit in Agisoft? or will I keep my range saving out my tiffs to exr? or will it be the same like converting my 8bit to 32bit when saving?

To get the higher bits workflow all the way do I have to use EXR all the way in agisoft?

Will the saving 16bit tiffs be fixed?

General / Sloooow Decimating Mesh..

« on: May 26, 2014, 03:55:17 PM »

What is causing Agisoft to be super slow when decimating some meshes? I have a project with different chunks. One chunk consist of 80 photos that I have generated a mesh from and one chunk with 94 photos. The first one took like 10 minutes to decimate the second one have been chewing for 1.5 hours now and still 6 hours to go.

The meshes are pretty much the same kind of object, sure the second one have more polygons but cant  understand why it will be such big difference in time..

General / ISO settings, f number and so on..

« on: May 25, 2014, 01:39:23 PM »

Hi everyone! A question about best settings for getting sharp photos. Im somewhat new to what would be a best general camera setting. I totally understand it will be from case to case, time of day, amount of light and so on. I dont expect a golden setting cause there is none I guess, but more a overall guide what is better and not.

As example, a cloudy day, using a hand held camera, I want as sharp picture as possible with minimal depth of field and motion blur. The only way I see to achive this is going up in iso setting. To keep depth of field away I assume it's getting F-stop to as high as possible (F13-F22). Then to keep the motionblur of shooting handheld is increasing shutter speed. To do this I only got ISO left to get the light in. I use a canon 5d mark III. People say you can go really high on iso on this camera before any noise appears.

So any general thoughts, tips of how you are working with the camera settings would be of great help!

General / Problem aligning photos

« on: April 11, 2014, 11:38:36 AM »

Hi
I have some problems aligning photos. I think it should be enough of pictures and overlap for Agi to solve it, but only 3 photos out of 11 get aligined.

Photos were taken with Canon 5D Mark III with a 50mm focal length. In the camera calibration it says pixel size 0.00625 x 0.00625.

Is there anything that looks wrong in camera calibration settings?

General / Batch processing?

« on: April 07, 2014, 10:34:56 PM »

Is it possible to do some kind of batch processing inside of Agisoft? Could you set chunks with different sets of picture and so on and leave it to chew them through over night? Or how is it with chunks, can it only do each step in the process for generating scans, first align photos then manually tell it to build point cloud and so on?

General / Export Undistort Photos

« on: March 21, 2014, 12:35:06 PM »

Trying to export my undistorted photos from Agisoft to use for projection in another software, problem is it just saves one picture. Looks like it's just overwriting the existing one. How should I tell it to save out each image seperatly?

In tools/export/undistort photos I set a file name to something I though would be good, is that the mistake I made? If so what should it say cause every time I restart Agisoft it still says the name I used before..

General / Change path/replace photos

« on: March 17, 2014, 12:28:43 PM »

Hi all! How do I change a chunk of 57 photos in jpg format to the same photos but in tiff? I right click the picture, choose change path select my first picture and choose replace active chunk but from there nothing happens it only replaces my first picture to the tiff version the rest are unchanged and still in jpg format. All photos are named the same except for the .tif from .jpg.

Do I need to replace all pictures by hand or how is it suppose to work?

General / Mudbox projection problems

« on: February 27, 2014, 12:51:20 AM »

Anyone else had or have problems using projections in Mudbox? I've done this before but today I just couldnt get it to work. I'm exporting my mesh and cameras with FBX format from Agisoft. Import it to Mudbox. Select one of the projection cameras, load the picture as a stencil. I see the picture but as soon as I start painting nothing happens. If I switch over to any of the other cameras like perspective, top or front and load same picture as stencil it works fine, but as soon as I try to use any of the cameras from my fbx/Agisoft file it just wont work.

Someone else had this issue?

General / Spikes and wavy patterns in my scans

« on: January 15, 2014, 12:13:42 AM »

On my latest scans I got a lot of spikes and these wavy patterns in my meshes. So I guess this is a basic questions for many of you. I have a scene made out of like 170 photos, been trying to capture a section of rocks/cliffs. To get as much detail as possible I have taking a lot of overlapping pictures in close range. Started sideways, left to right, and in between tilted and rotated camera to get details in all angles.

I've done similar before but not getting so much noisy result as I'm getting now,  so, am I doing something against all rules of Agisoft workflow? Is it a setting issue? Tried medium and high settings when genrating point cloud medium smooths thing out a little better but looses a lot of details.

Tried cleaning in Zbrush but have too much of this "tube" shapes so cant smooth them out good enough.

General / Align photos point limit

« on: January 08, 2014, 04:33:47 PM »

Can someone please explain to me what this Point limit within advanced in the Align Photos window does. Will I get a better scan/detail if I change it to 80000?

General / Exr 32bit in and out?

« on: December 16, 2013, 03:51:03 PM »

Hi everyone! Been searching the forum before I post this, found some information but I still need some confirmation about using raw/exr 32bit files in Agisoft for texture creation.

If I use 32bit raw files converted to exr. Pipe them into Agisoft and after generating my mesh I build texture, will that texture still be 32bit or have Agisoft converted them to 8bit during it's mesh process?

Cheers!
