General / How to obtain a smooth surface?

« on: February 14, 2019, 06:15:59 AM »

Hey there just wondering if there is a way to smooth out an object before the texture is made, because the geometry comes out very rough.

General / Merging chunks question for a cadaver's leg...

« on: November 15, 2018, 09:23:21 AM »

Hey there I've been watching these tutorials https://youtu.be/pYE0KOa5oGk?t=1018 merging two chunks with markers and I tried it with my model but it's not working.

Do the 2 chunks need to be in the exact same position, ie I'm doing a cadaver's leg where the leg was shot firstly in this position...



(ie calf facing downwards)

and then in this position...



(ie calf facing upwards)

Unfortunately when moved they change slightly (because, well it's a leg), so when I go to merge the 2 chunks of it will Agisoft just merge them on top of each other or do I have to cut away parts of the model I dont want with a little bit of overlap, like so (where red is the overlap)...



or is this just not going to work (ie it would be better if the leg was suspended from the roof to get as many shots as possible)

Unfortunately I can't show my model for privacy reasons because it's a cadaver (I work for a university).

General / Reset current alignment doesn't work

« on: May 16, 2018, 03:04:16 AM »

Hey there I'm not sure what I'm doing wrong but after I had completed a model up to the texture stage I decided I wanted to align the photos again (since I used the Medium setting and now wanted to try High).

Here's my textured model...



and it's settings...



But when I align the photos with Reset current alignment on...



it ends up with a model with 0 tie points...



Am i missing something?

Thanks in advance.

General / 75% of subject disappears when Building Dense Cloud

« on: October 25, 2016, 04:17:24 AM »

Hey there,

I've never had this before but after Aligning the Photos and removing unwanted points, I go to Build the Dense Cloud and when it finishes and I preview it with the Dense Cloud button and 75% of the subject disappears!!!

See here for a video screen grab...

What am I doing wrong? I've never had this before!

Thanks in advance.

General / Turntable issues.

« on: March 21, 2016, 07:23:37 AM »

Hi there we're having weird results using a turn table and I'm sure we're missing a simple step and thought you guys might be able to help us.

We seem to get good results when photographing a subject when walking around it, but when it comes to a turntable subject all the cameras seem to align from one direction (we're using a Canon 6D) rather than in a circular direction, see below (we tried on a turn table and also turning the subject on a tripod with a red screen to use as a mask to see if the mask would help).

We've turned GPS off on the camera, and have markers rotating with the subject, but can't think why else this would be happening.

Any ideas?

Thanks in advance.

General / Turntable photos project from one direction!

« on: May 14, 2015, 07:30:27 AM »

Hi there,

we've tried our 2nd attempt using Photoscan and we're wondering if it's not working for us because we're shooting objects rotating on the spot rather than us physically moving around the object.

We tried this boot...



but as you can see the blue camera orientations are all projecting from the same direction, whereas shouldn't they be projecting from all around the 3d space, like this video with his turntable example https://www.youtube.com/watch?v=9_F-b2hxP_o

Are we missing a setting or is the camera itself mucking it up?  It's a Canon EOS 400D.

Thanks in advance,

General / First try not working (food photos)

« on: April 30, 2015, 09:25:39 AM »

Hey there so excited to give this a go for the first time.

Had a photoshoot recently for some food shots and decided while we were at it to use one food as a test piece to use Photoscan.

Unfortunately it doesn't seem to be working as expected.

We did 33 photos that look like this



but when I Align Photos (even with masking)



I'm getting this result



Where the projected photos only seem to be projecting from the same-ish area and not in a circular projection as I expected. I know the photos are of a white plate on a white background (which is only what we had at the time) so is this mucking it up? Or is it because we had the camera on a tripod and we turned the plate around?

Thanks in advance and look forward to your replies.
