README

What is this repository for?

  • To Predict Object Detection using Tensorflow Object Detection API on Raspberry PI
  • Version 1.0

How do I get set up?

Install Tensorflow and other dependencies:

sudo apt-get install libblas-dev liblapack-dev python-dev libatlas-base-dev gfortran python-setuptools
sudo pip install http://ci.tensorflow.org/view/Nightly/job/nightly-pi-zero/lastSuccessfulBuild/artifact/output-artifacts/tensorflow-1.4.0-cp27-none-any.whl

Clone Tensorflow Object Detection API:

git clone https://github.com/tensorflow/models.git

Configure API using protobuf

sudo apt-get install -y protobuf-compiler
cd models/research/
protoc object_detection/protos/*.proto --python_out=.
add path to bashrc
export PYTHONPATH=$PYTHONPATH:/home/pi/models/research:/home/pi/models/research/slim

Copy trained model on pi

Train a model to run on raspberry pi using this repo

https://github.com/NanoNets/RaspberryPi-ObjectDetection-TensorFlow

Copy exported model and label file from data directory to raspberry pi

other Packages required
sudo apt-get install libjpeg-dev
sudo pip install Pillow
