Raspberry pi 4 TensorFlow Object Detection
On June 2019 Raspberry pi announce new version of raspberry pi board.
Now we have a new raspberry pi 4 model B 1GB So try to run TensorFlow object detection and then compare with Raspberry pi3B+ also.
Install TensorFlow on Raspberry pi4
Add some dependency
sudo pip3 install grpcio
sudo pip3 install h5py
Then Download tensorFlow
https://www.piwheels.org/simple/tensorflow/tensorflow-1.13.1-cp37-none-linux_armv7l.whl#sha256=25f4ff027beec1e568baf8e90a07bad59d354560533d6b37318b9efeb70beeb1
sudo pip3 install tensorflow-1.13.1-cp37-none-linux_armv7l.whl
Summary Software for test.
Python 3.7.3
OpenCV 4.0.0
Tensorflow 1.13.1
Run Tensorflow Object Detection
Video MP4 768x432 12 fps
run on the same img os in same sd-card.
Raspberry pi 4 is 2.xx fps .
Raspberry pi 3 is less than 1 fps.
So, only Raspberry pi Board is not faster enough for tensorFlow object detection application.
Then next we use raspberry pi with intel neural compute stick for better performance.
