The idea is to project an informative following image or a small animation at the foot of passersby.
- for tracking walking people I'm using a LIDAR (scanse sweep) with a blob's centroids detection script based on the Sklearn Library
- for moving the micro projector I'm using a drone gimbal plugged to Adafruit Pi PWM Hat
- for computing everything I'm using a raspberry Pi B+
TODO :
ajust gimbal position to follow the centroids detected by the script
#---- Rasp Pi OS updates ----

#clone the scanse sweep lib and build the sweepsdk to get the libsweep.so :
git clone https://github.com/scanse/sweep-sdk.git
cd sweep-sdk/libsweep/
sudo apt-get install cmake

cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .

#in the sweeppy rep run install.py:
python3 setup.py install --user
#to listen the scanse lidar output use the command :
python -m sweeppy /dev/ttyUSB0
#Adafruit Servo Hat install :
sudo pip3 install adafruit-pca9685
