# MobileNet-SSD-RealSense
RaspberryPi3(Raspbian Stretch) or Ubuntu16.04/UbuntuMate + Neural Compute Stick(NCS/NCS2) + RealSense D435(or USB Camera or PiCamera) + MobileNet-SSD(MobileNetSSD)

**【Notice】December 19, 2018 OpenVINO has supported RaspberryPi + NCS2 !! 
https://software.intel.com/en-us/articles/OpenVINO-RelNotes#inpage-nav-2-2** 
 
**【Dec 31, 2018】 `USB Camera + MultiStick + MultiProcess mode` 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)

## Summary
**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

```
$ rm -r -f build
$ rm -r -f .build_release
$ make superclean
$ make all -j4
$ make test -j4
$ make distribute -j4
$ export PYTHONPATH=/home/<username>/caffe/python:$PYTHONPATH
$ make py
```

3.Download of VGG model [My Example CAFFE_ROOT PATH = "/home/\<username\>/caffe"]
```
$ export CAFFE_ROOT=/home/<username>/caffe
$ cd $CAFFE_ROOT/models/VGGNet
$ wget http://cs.unc.edu/~wliu/projects/ParseNet/VGG_ILSVRC_16_layers_fc_reduced.caffemodel
```

4.Download VOC 2007 and VOC 2012 datasets

```
# Download the data.
$ cd ~;mkdir data;cd data
$ wget http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar #<--- 1.86GB
$ wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtrainval_06-Nov-2007.tar #<--- 438MB
$ wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtest_06-Nov-2007.tar #<--- 430MB

# Extract the data.
$ tar -xvf VOCtrainval_11-May-2012.tar
$ tar -xvf VOCtrainval_06-Nov-2007.tar
$ tar -xvf VOCtest_06-Nov-2007.tar
$ rm VOCtrainval_11-May-2012.tar;rm VOCtrainval_06-Nov-2007.tar;rm VOCtest_06-Nov-2007.tar
```

5.Generate lmdb file
```
$ export CAFFE_ROOT=/home/<username>/caffe
$ cd $CAFFE_ROOT
# Create the trainval.txt, test.txt, and test_name_size.txt in $CAFFE_ROOT/data/VOC0712/
$ ./data/VOC0712/create_list.sh

# You can modify the parameters in create_data.sh if needed.
# It will create lmdb files for trainval and test with encoded original image:
#   - $HOME/data/VOCdevkit/VOC0712/lmdb/VOC0712_trainval_lmdb
#   - $HOME/data/VOCdevkit/VOC0712/lmdb/VOC0712_test_lmdb
# and make soft links at examples/VOC0712/

$ ./data/VOC0712/create_data.sh
```

6.Execution of learning [My Example environment GPU x1, GeForce GT 650M = RAM:2GB] 
Adjust according to the number of GPU
```
# It will create model definition files and save snapshot models in:
# - $CAFFE_ROOT/models/VGGNet/VOC0712/SSD_300x300/
# and job file, log file, and the python script in:
# - $CAFFE_ROOT/jobs/VGGNet/VOC0712/SSD_300x300/
# and save temporary evaluation results in:
# - $HOME/data/VOCdevkit/results/VOC2007/SSD_300x300/
# It should reach 77.* mAP at 120k iterations.

$ export CAFFE_ROOT=/home/<username>/caffe
$ export PYTHONPATH=/home/<username>/caffe/python:$PYTHONPATH
$ cd $CAFFE_ROOT
$ cp examples/ssd/ssd_pascal.py examples/ssd/BK_ssd_pascal.py
$ nano examples/ssd/ssd_pascal.py
```

```
# Solver parameters.
# Defining which GPUs to use.
gpus = "0,1,2,3"
↓
# Solver parameters.
# Defining which GPUs to use.
gpus = "0"
```

Adjust according to GPU performance (Memory Size) [My Example GeForce GT 650M x1 = RAM:2GB]
```
# Divide the mini-batch to different GPUs.
batch_size = 32
accum_batch_size = 32
↓
# Divide the mini-batch to different GPUs.
batch_size = 1
accum_batch_size = 1
```

Execution
- The learned data is generated in "$CAFFE_ROOT/models/VGGNet/VOC0712/SSD_300x300"
- VGG_VOC0712_SSD_300x300_iter_n.caffemodel
- VGG_VOC0712_SSD_300x300_iter_n.solverstate
```
$ export CAFFE_ROOT=/home/<username>/caffe
$ export PYTHONPATH=/home/<username>/caffe/python:$PYTHONPATH
$ cd $CAFFE_ROOT
$ python examples/ssd/ssd_pascal.py
```

7.Evaluation of learning data (still image)
```
$ export CAFFE_ROOT=/home/<username>/caffe
$ export PYTHONPATH=/home/<username>/caffe/python:$PYTHONPATH
$ cd $CAFFE_ROOT
# If you would like to test a model you trained, you can do:
$ python examples/ssd/score_ssd_pascal.py
```

8.Evaluation of learning data (USB camera)
```
$ export CAFFE_ROOT=/home/<username>/caffe
$ export PYTHONPATH=/home/<username>/caffe/python:$PYTHONPATH
$ cd $CAFFE_ROOT
# If you would like to attach a webcam to a model you trained, you can do:
$ python examples/ssd/ssd_pascal_webcam.py
```
