Capturer Setup
For the needs of the capturing system, 4 Intel NUC ,4 Intel Realsense D-400 Series and a high-end desktop workstation are required, as well as 4 tripods(standard digital camera tripods e.g.) and mounting stations for the devices and a LAN switch.
Our application was built and tested under Windows 10 operating system. In order to use the application, some Windows settings have to be set to each Intel NUC (listed below).
Steps to setup Intel NUC :
- Disable Windows Updates. (how to)
- Configure Local Time Zone to all devices.
- Enable Remote Desktop. (how to)
- Enable High Performance Settings. (how to)
- Disable USB power management. (how to)
- Install remote-eye application and Remote Eye Windows Service. (how to)
-
In order to easily represent a device by a user friendly unique name instead of serial number, adding and naming every device to the repository is highly recommended. A detailed manual is present here.
-
The steps to setup the workstation PC are described in detail here.
We take into serious account the fidelity of our multi-view data during the capturing phase. The simultaneous triggering of all acquizition processes between different cameras is realized with external hardware synchronization cables. In case you need more detailed description regarding the hardware synchronization cables visit our Synchronization Cables Section.
Intel RealSense devices offer the option to externally trigger multiple devices (which serve as Slave devices) via the signal of another device (that serves as the Master device). This done by using the GPIO port placed on top of the device.
In order to use this option you will have to assemble a set of cables that enable the Master device to send trigger signals to the Slave devices. Here is the list of materials for a cable that connects one master device with one slave:
-
2 x Connector Housing.
-
If you only want to use the GPIO port for external syncing between the system's devices then you need only two cables. However, if you want to use any features that may become available by Intel (and make use of other pins of the GPIO port) in the future, then you will need 9 cables for each device-to-device connection. We recommend a good shielded 9-core ribbon cable like this.
-
Additionally, you will have to get 4 (or 18) x connector contacts.
-
If you cannot assemble your own cables, there is a chance to find and purchase ready-made cables but with not many options regarding length.
-
You can find further instructions about assembling the hardware sync cables in the corresponding Intel's white paper.
The hardware synchronization of the Kinect for Azure devices is much easier as the required synchronization cables are standard 3.5-mm audio cables. Microsoft Docs provide a detailed description of the cables and the hardware cables configuration between multiple devices.
Once all of the above steps are completed, you can launch the application which is under volumetric_capture folder at Releases by double clicking volumetric_capture.exe.
