This Technical Note (TN for short) illustrates an interesting use case of the i.MX8M Plus-powered [[ORCA_SBC|Orca Single Board Computer]]. In a nutshell, this example demonstrates the following functionalities, which are typical for many video processing applications:
* Capturing live video streams from MIPI CSI-2 cameras
* Hardware-accelerated GUI (GPU)
Basically, the testbed consists of two Orca SBC's connected as shown in the following diagram.
TBD
Orca SBC #1 is also interfaced to the following camera modules by Basler:
*daa2500-60mc
*daa3840-30mc
Both SBC's run Yocto Linux based on the 5.4.70 BSP by NXP.

==Camera modules interfacing==
The camera modules are connected to the MIPI CSI-2 ports of the i.MX8M Plus. Each one exploits 4 MIPI lanes.
The camera modules are configured TBD

===Social Distancing algorithm===
The Social Distancing algorithm is described in detail in [[ML-TN-002_-_Real-time_Social_Distancing_estimation this document]].
==GUI==
A GUI application runs on the Orca SBC #1 too. This application is engineered with [https://www.cranksoftware.com/storyboard Crank Storyboard 6] and shows some parameters of the Social Distancing algorithm.
