My objective is to capture raw clouds (frames) with no tranformations applied. To achieve this would I need to set both base and target frames of reference to COORDINATE_FRAME_DEVICE?

I'm using a much more accurate external tracking system and will be synchronizing data between the two systems to handle integrating the model. Would just like a normalized coordinate system prevent error introduced by tangos normalization to reference frame.

Hi, does anyone know available microUSB OTG to RJ45(ethernet) adaptor for Phab 2 Pro?

4 Phab Pro and RTAB MAP would work too.

I just had to share this scan. Under the right lighting conditions the Phab2 produces an amazing point cloud. The colors are really nice and there is very little drift. I wonder what the next generation of hardware is going to bring? If scanning tech advances at the same rate as digital cameras then we will have photo quality in 2 generations....

i want to make a app using unity in which a dog follows me. but i am not able to store the my position. i think so we can store my all walking postion using tangoPose. but i do not know how to take the position from tangoPose for the dog to follow. plzzz help

For an easy way, look at Unitys (assuming you're using unity) Camera.main docs.unity3d.com - Unity - Scripting API: Camera.main which has a transform.position property. Assuming you have a single camera tracking the device you can just use that. Camera cam = Camera.main; Debug.Log(cam.transform.position);

But to get the Pose objects, the better way would be to use https://developers.google.com/tango/apis/unity/reference/class/tango/pose-provider#getposeattime and make sure your pose is correct for your frame timestamp. Then from the TangoPoseData you get populated from that call, you look at transform.position etc..

Have fun! (:

Make it actually work with Google maps direction API. That would be a first.

Does anyone have experience using Area Learning for "object learning"?

I understand that Area Learning is made to learn an area, but my thinking is that if you have big enough objects it could learn those as well. I've tried to put a dishwasher sized object in the middle of a big room. Unfortunately the device (Phab 2 Pro) manages to capture the room instead of the object.

When doing the Area Learning I've tried to avoid scanning the walls but I guess the 170 degree fisheye camera is wider than I realise.

Any suggestions welcome.

Tensorflow on the Phab is great.

Anyways Raf just wants to see how everyone is. Raf now speaks in the third persons. Yes multiple persons. Raf is to lazy to fix the typos.

I made a few experiments with extending ADFs and discovered an apparent file size limit for extending ADFs.

All ADFs larger than around 60MB would cause the Tango Service to stop, after some time I get a TangoErrorException in my own app and a Screen showing "Faild to connect to Tango. Please restart application" with Tango Explorer.

This occured with multiple ADFs, some where already extended once or even twice, others were als large as 130MB and recorded in on go.

I can't find any mention about this in the official documentation.

My impression is, that there might be some kind of timeout when the Tango service is starting, and larger ADFs take longer to load/reopen.
But this is just a theory based on the fact the time between starting the Service and the error seems to be about the same, no matter the file size.

Using the same ADFs just for localization works just find.

Can anybody confirm this issue or even has a solution/workaround for this?

My plan was to improove recognition in an area with changing light (as suggested in https://developers.google.com/tango/overview/area-learning).

Large scans with RTAB-Map
After a test mapping of a small cavern ( https://skfb.ly/ZnQ8 ), a few days ago I made this scan of a "large" natural cave. Since it was larger than the previous one, I made it in four segments.
While I'm still learning to use the best settings of MeshLab to get the best possible conversion from a point-cloud to a mesh, I found some difficulty with RTAB-Map, both on mobile and PC.
With RTAB mobile I had some small misalignments inside the cave (i.e. the bench), perhaps due to the low light but I'm not worried about that, I do not need a millimeter precision. Once imported into MeshLab, the three interior sections overlapped almost perfectly. With the fourth segment, the outer one, I had some very big problems of misalignment, as you can see in the middle of the central field there is a rectangle ground raised by at least half a meter above the surrounding land.

What I'm asking is:
- Is there a way to minimize the chances of this happening during the scan? What RTAB-Map Mobile settings should I use to get the best mappings? "Localization Mode", "Filtering Nodes" "Drift Correction"? Which movement technique?
- Is there a way to correct these misalignments in RTAB-Map PC? I tried various options in "Post processing ..." but I did not get such improvements to correct that big flaw at the center. The tutorials are a bit outdated https://goo.gl/fljMgj
- Is it possible to manually correct the misalignment in RTAB-Map, perhaps by changing the "inclination" of some nodes?

Thanks!

This scan has been made in one hour with Lenovo Phab 2 Pro pushed to the limits of its hardware, it was heating up and slowing down, fortunately without crashing. I can't imagine how it could be using an Asus Zenfone AR with the better hardware it has... Hello Asus, any spare? Do you need a tester? ;) :D
First test scan of a large natural cave: “Grotta Sopra Longera” Trieste, Italy. The bench and pallets give you an idea of the size of the cave. Scanned with RTAB-Map in 4 times. The external scan has a large mis-alignment at the center of the terrain. Point-clouds aligned in Meshlab. This is just a low quality test. The original point cloud in RTAB-Map “.db” files is very large, in total almost 850MB. I need to learn how to apply textures to low ...

Greatest thread ever. +Mathieu Labbé I've not been able to project (correctly aligned) textures back from the db onto exported cloud mesh. Should i provide a dbfile with an issue on github?

Screen capture applications like Team Viewer / Screen Record etc doesnot work on Project Tango tab.
They ask to root the device.
I'm wondering why??? Is it because Tango tab runs KitKat or someting else....
If so then how does Google guys are sharing their screen in their demos.

Just in case, if I root the device I'm not sure if Tango capabilities will run properly.

Help!

For the Tango Tablet, I have both
- rooted and used recording app
- tethered an HDMI portable recorder that put in messenger bag I carried with me. This was highest quality option with no perf issues (one I used- it is almost pocket sized but it is thick: atomos.com - Ninja 2 - Atomos )

You could get a separate workstation prepared by doing this:
1. https://developers.google.com/tango/apis/unity/
then create a simple App with a sphere (3D obj)
2.https://developers.google.com/tango/apis/unity/unity-howto-motion-tracking

would be one possibility to get in touch with the core....
