General / measuring length for a structure

« on: March 29, 2015, 04:07:10 PM »

Is there any way to measure the length and width of a structure in photoscan based on just x,y data (no height).  I attempted to manually input 4 control points (corners of a square building), but it would not let me draw a scale bar based on those. I do not have the camera's gps positions.   Anyone have ideas?

General / Can't Build Dense Cloud Error

« on: March 26, 2015, 04:03:56 PM »

Hi all,
Can anyone give any insight as to why this error may occur? 

Background:  I took 20 photos of my Mazda 3, just to play around with the program and see if I could make a model.  I am running into a number of issues:

1. Not all photos are being aligned. I can only align 2-3 photos at a time.  The overlap between pics looks decent enough.

2. Can't Build a Dence Cloud.  I tried to run the Dense cloud tool on the 2-3 photos that aligned, and got this error.  Does anyone have any ideas why this happens if the photos align correctly?

Thanks.

Ha anyone used something like the Nikon GP-1 for georeferencing points?  I was doing some research and it seems like there are better systems (Solmeta), but I have not been able to find anything on accuracy.

Thanks Igor, do you happen to have a good staple of fixed lenses that you usually use?  Also, and this may be a terribly silly question, but what features would I use on the 7100?  I am very much still a novice, but I this is something that I want to pursue due to the lack of this service in my area.

What would you guys suggest for a camera to use for photogrammetry?  I was looking online, and I notice many people use the Nikon D600, but it seems a little pricey.  Personally I was looking at the D3200 as it costs significantly less, and I am comfortable in that price range.  Can any one tell me if I can get by using the D3200?  Does anyone have any other suggestions?

The type of work is mainly going to be modelling of historic structures.  Thanks for your time.

General / Trouble with domed structure

« on: March 15, 2015, 08:50:36 PM »

Hello. I am working on a historic site in the middle east, and am having diffuculty getting the model to work.  This structure is unique in that it has two domed roofs.  The attachement example 1, shows the main dome of the structure.  Example 2 shows a smaller dome on the annex.  I also attached a photo that demonstrates the relationship to each other. 

Both domes seem to not line up correctly.  You can see in the example pics that there are features on the domes that are offset.  Does anyone have any ideas on how I can get this model to work better?

Thank you, I have not used blender; is it difficult to work with?

General / Creating a generic roof for a model

« on: March 15, 2015, 12:01:56 AM »

Hello Everyone,
I am new to photogrammetry and agisoft, so forgive me if this is a silly question.  I wanted to ask you fine people if there was a way to create a generic roof for a single room building.  I managed to get a decent looking model from all sides, but I could not get any photos looking down on the roof.  I'd like to close the model somehow.  Any ideas are appreciated; thank you.
