correspondence with NCS2 is completed.
【Jan 04, 2019】 Tune performance four times. MultiStickSSDwithRealSense_OpenVINO_NCS2.py. Core i7 -> NCS2 x1, 48 FPS
【Nov 12, 2019】 Compatible with OpenVINO 2019 R3 + RaspberryPi3/4 + Raspbian Buster.
Measure the distance to the object with RealSense D435 while performing object detection by MobileNet-SSD(MobileNetSSD) with RaspberryPi 3 boosted with Intel Movidius Neural Compute Stick.
"USB Camera mode / PiCamera mode" can not measure the distance, but it operates at high speed.
And, This is support for MultiGraph and FaceDetection, MultiProcessing, Background transparentation.
And, This is support for simple clustering function. (To prevent thermal runaway)

Performance measurement result each number of sticks. (It is Detection rate. It is not a Playback rate.)
The best performance can be obtained with QVGA + 5 Sticks.
However, It is important to use a good quality USB camera.

(Example5) To prevent thermal runaway, simple clustering function (2 Stick = 1 Cluster)
When a certain cycle or constant temperature is reached, the active cluster switches seamlessly automatically.
You must turn on the clustering enable flag.
The default switch period is 10 seconds, the default temperature threshold is 65°C.
The number, cycle, and temperature of sticks constituting one cluster can be specified by the start parameter.
Depending on your environment, please tune to the optimum parameters yourself.
[1] Number of all sticks = 5
[2] stick_num_of_cluster = 2
[3] cluster_switch_cycle = 10sec (10,000millisec)
