General / Re: Can´t build dense cloud

Wow that was fast Alexey,

I've solved the problem thanks to you, It was indeed the bounding box. I activated it and it was extremely small and out of place...

Why did that happen ?


General / Can´t build dense cloud
« on: January 29, 2015, 02:52:16 PM »

I've been trying for a while to scale my model using the system -very well explained- in IR webpage.
This is what i am doing:

1. Align photos using 90.000 and 0 tie points. High quality
2. My hand has two dots with 5mm separation. I place marker 1 at one point and marker 2 at the other point
3. I create a scale bar with those two points
4. I write on the distance tab 0.005 (m) with corresponds to 5mm separation
5. I push "update"

-- After optimizing i get this error when trying to build the dense point cloud.
- I am using the latest 1.1 build-

Any suggestions ? (i might be doing something stupid and wrong?) ^^

Im planning to buy around x10 and x10 50mm 1.8f lenses with Canon EOS 5D Mark III body
Does anyone know / or have experience with any dealer in Europe that could make a special price for that amount of cameras ? ive found a dealer that is selling them for about 2k euro each body, but i'd love to know suggestions from you!


Feature Requests / Non rigid chunk alignment.

What the title says! there are great libraries about non rigid alignment. That would be awesome for facial scans  :)

Indeed! Just told that to my colleague engineer. I've found some really cool and tiny pin-connectors female/male used for radio control cars power supply.

I've just applied the high pass and Lo Minimization denoise algorithm & basic AO. Everything is very subtle though, might not be noticeable at that resolution.

Thank you mala,

Prototype updated.

Here's a little update of how the prototype is progressing and updated results.

- No high pass filter applied
- No denoise
- Just how it came out of Agisoft.

Illumination is definitely improving scans! I am still on the process of comparing results taken at f16 and at f22.

Thats incredibly cool mala! *Claps*
Great video-marketing as well  ;)

I hope to post something this coming weekend, we had some issues with the PCB suppliers (Newbury on UK)...
15 flashes are already mounted, 15 assembled and ready to be mounted. Its working wonders at the moment.
Meanwhile im playing with Canon SDK...

I hope to post some photos and a video!  :D

Speak soon!

Its looking incredible mala, good job!  :)

Im building from scratch the tiniest flashes on the market (i hope!), to attach 30 low power flashes to my hemisphere, each of them will have a diffuse layer paper and polariser. The housing is (60mm diameter and 12 cm height), almost no recycle time.

I will post news soon at the end of the month.
( I tried the LED solution, but it didnt work for me  :-\)

General / Re: How to show online high resolution maps?
« on: June 04, 2014, 05:44:55 PM »
I dont know pretty much for maps...
But for my high resolution images i use Krpano or Pano2VR, they're not free although...  :)

I understand :)

I'd love to see results of this method. Are you planning on uploading everything to high res viewers ?

Im using this system:  works slightly better than papywizard. Its significantly more expensive tho.

If you place the lens to rotate around its optical axis you wont have perspective issues when aligning and stitching images on Ptgui. You can also autofocus on each image and check images to have a different FOV between each other to compensate when optimizing.
You're having problems because you're scanning from different positions. This can be avoided.

Photogrammetry is another approach, but you cannot export 16bit.
Hope what im saying helps :)
