Dab and T-Pose Controlled Lights
Control your lights by dabbing and t-pose'ing, duh

Getting the ZWave Controller working on the TX2
By default, I couldn't write to the
/dev/ttyACM0 device that the ZWave USB controller came up on with my NVDIA Tegra TX2.
You'll need to do something along the following to get permissions:
$ sudoedit /etc/udev/rules.d/50-myusb.rules
Followed by inserting the following lines to add perms to the
Getting an OpenPose Model running on the TX2
There are two ways, I started out by using the original OpenPose repo to get a build and proof of concept running.
probably half a frame 1.4(ish) frames per second out of that. You can see how I initialize and use the built in devboard camera in the
01_body_from_image.py file in this repo. That comes directly out of the included Python examples.
Because I wanted better response time, I ended up searching for a better model. I found tf-pose-estimation.
It requires Tensorflow, so be sure to grab the latest Jetpack release from NVIDIA here when installing.
After that, it should run with the included
run_webcam.py, just be sure to run it with the right model. Mobilenet_v2_large was the bare minimum for an acceptable detection for me:
$ python3 run_webcam.py --model=mobilenet_v2_large --resize=432x368
With this model, I get 4(ish) frames per second on the TX2, much better for detection latency. I may try seeing if I can optimize further after getting a full proof of concept running.
Exploring OpenPose Data and Training a New Classifier
We'll use some saved examples of T-Poses and Dabs in order to train our classifier. You can see the Jupyter notebook here with examples of labeling and converting our raw
npy Numpy exports to CSVs and Pandas datasets, along with cleanup and training.
The current (working) architecture looks like this:
Running the Project Itself
You'll need to get OpenPose up and running, along with the Python libraries for OpenCV and ZWave. After that, you can use the included program, just run it under the
If you want to grab more example poses for retraining, just replace the
01_body_from_image.py with the one included in this repo's
For some reason, the model test I run on my original
y dataset doesn't seem to work. I think I messed the data up somewhere along the way in the Jupyter Notebook. If you figure out where that happens, open a PR please. :)
