Occipital Structure Scanner Questions

[jonah hex]

Can you use a structure scanner to get color scans without the use of internet and/or a pc?

I saw it somewhere that structure scanner:

1) cannot scan without connected to a pc/laptop

2) cannot color-scan if connected to a pc/laptop via a hacker cable

3) can only color-scan when connected to the internet via wifi

So if I have a structure scanner on my ipad air 2, it doesn't do anything.

If i have the setup connected to my laptop with a hacker cable, it can only do monochromatic scan

Only if I connect the setup with my laptop via wifi to the internet, then it can do color scan

Are all these true?

Does Skanect solve these problems?

Hello,

Please submit your questions to ska...@occipital.com, if you have not already, for a more detailed response. I am reposting answers to similar questions, possibly originally asked by you, below:

---

The Structure Sensor Mark II can scan a full (human) body and the iPad Air 2 is a supported host device.

There is a sign-up to be notified when Skanect will be updated to support the Structure Sensor Mark II on this support page: https://support.structure.io/article/397-how-do-i-use-skanect-pro-with-my-structure-sensor-mark-ii

The first update will be Uplink support for a Structure Sensor Mark II attached to an iPad running the Structure app to connect over WiFi with Skanect running on a Windows or macOS device. Support for directly connecting a Structure Sensor Mark II to a device running Skanect with a USB cable is expected sometime mid-2020. Please note that a Structure Sensor does not have an onboard color (RGB) camera so scans made with a Structure Sensor directly connected to Skanect will lack color.

The Skanect Pro license is supposed to be for 1 year of minor updates but since Skanect was released (in 2013) we have never charged for an upgrade or support plus there is no method available to renew a subscription or license. This policy may change in the future but for now it is, effectively, a perpetual license.

Skanect is a capture app with some post-processing features of scans captured with Skanect. It does not support the importing of scans made with other apps, exported by Skanect or have the ability to merge multiple scans; you can use MeshMixer for that.

The original Structure Sensor (Mark I) cannot scan in bright, direct sunlight but the Structure Sensor Mark II can.

Please note that the Structure Sensor, both models, does not have a color (RGB) camera and only captures depth for constructing 3D models. If you want capture color you will need to attach the sensor to a supported host device (iPad) and use the Uplink feature of the Structure app to connect over WiFi to a device running Skanect. WiFi connections do not require an external router, however, as you can configure an ad hoc or point-to-point network between two devices.

You can also eschew Skanect altogether and just use iOS apps, like our free Scanner app, to capture and create colorized 3D models. Scanner, however, limits the resolution to 50K vertices which is not very high; for comparison, Skanect can capture over 1M vertices.

Thank you for your interest in Skanect,

-Scott

I have the Mark II and iPad 6th gen, have downloaded the updated Skanect app, and after getting an email saying that the Mark II is now fully supported by Skanect Pro on Windows, I am having the exact same issues with scanning.

Immediately after initiating the scan, the app freezes and gives an error that I have moved too much or there is not enough geometry.  

I am very curious how I am supposed to get he Mark II working. 

Until that time, I am still using my old Mark I.

Please send a support ticket to ska...@occipital.com

From your initial description there may be an issue with your Structure Sensor that can be resolved by re-calibrating it with a special app other than Calibrator. Sometimes the twin internal depth sensors within the Structure Sensor Mark II can be out of alignment causing a near-immediate loss of tracking. It can also be caused by the scan subject itself like an object with no distinct edges or vertices, reflective surfaces, transparent materials or a very small object so, please, include sample images of a typical subjects.

Thanks in advance,

Hi Scott,

I'm currently facing the same issue with Structure Sensor (Mark I )

Uplink is working, the devices connect immediately and I can see the live depth-feed.

As the sensor mark I does not have an RGB camera onboard, color+depth wont' work at the moment, correct?

Depth+Color uplink fails immediately.

As i start scanning in depth only mode, it immediately fails with "Moved too fast or not enough memory" followed by "Go back to last pose". I've tried any combination of settings so far - no luck.

Can you please elaborate, what special app other than Calibrator is to be used?

My setup:

Structure Sensor (Serial 62791)

Firmware 2.0

Host device: iPad Pro (2. gen)

Tried two different desktops with the exact same result:

macBook Pro mid 2014 running macOS Mojave (no dedicated GPU)

2nd machine: Windows 10

i4770k

GTX 970 SLI (2x)

Networking:

5GHZ Wifi Network (ipad)

Gigabit Ethernet on Desktop.

I've also tried direct Wifi to the macbook.

The last few hours have been quite frustrating. Any help would be greatly appreciated.

Thanks in advance!

Hello,

Do you have the current version of Skanect (1.10.2) installed? Also, in case you have installed multiple versions of Skanect for Windows, be sure that you are launching the correct version because Skanect's installation procedure (for Windows) does not automatically update the desktop icon/shortcut.

Direct download links for Skanect 1.10.2:

Windows

macOS

The only way to capture color with a Structure Sensor, either original or Mark II, is to connect the sensor to a supported iOS device so that it can integrate with the iSight camera. Uplink is a feature of an iOS app and Color + Depth should work -- if the sensor has been successfully calibrated on that device.

The Structure Sensor Mark II has twin internal sensors that can be (or go) out-of-alignment whereas the original Structure Sensor has a single internal sensor. The special app that I referred to above is "Expert Calibrator" which supports a function to re-align the twin internal depth sensors of a Mark II. There is no need for this function with an original Structure Sensor (Mark I).

Best,

-Scott

I just put together a second machine that is i7-4770k with a gtx 970, during scanning i ran out of memory. *8gb ram vs my other desktop that has 16"  i went into the option and upped my paging file to 2432, which took care of the memory issue and kicking out durning scanning.(rebooted to lock it in). Before doing so i could not complete a single scan. it would start capturing and when i went from mid to top of their head, it kicked out of Skanect. after adjusting the "Virtual memory"(paging file) and a reboot, i no longer had the problem.

Hi Scott,

after some time, I'm trying to pick up where I left off - thank you for your support!

I am positive about having the latest version of Skanect, latest Version of Structure Uplink App, latest Version of iOS, up-to-date Sensor Firmware.

All errors persist, sadly.

A point into the right direction would be greatly appreciated! Thanks!

Hi Scott,

still desperately awaiting your reply. I would really like to test out some scanning workflows with Skanect using my Structure Sensor Mark I.

Thanks!
