This repo aims to build an android app to stream phone camera feed to a computer using sockets.

Download the apk file at link on to your android phone and install it on your phone. Download server.py on your computer. Make sure the computer has python3 installed.

Make sure that both the phone and the laptop are connected to the same network.

Run the following command on your computer.

python3 server.py <ip-address of your computer> <an open port on your computer>

To get the ip-address of your computer, run the following command ifconfig and find the inet value.

Run the app on your phone. Make sure to grant permission for the camera.
Enter the correct server IP and PORT. Press any of mode that you would like to use.

One could extend the display_image() function in server.py to do almost anything that they want to with the frame. For example, the received frame is passed through a darknet neural network for inference.

There have been a lot of times when I needed to test out some Image Processing or Computer Vision algorithms. An issue that I used to face was trying to get a proper test image. I either had to take pictures, download them to my computer and then run my algorithm or I had to use the built-in camera on my computer. Both methods have serious drawbacks. Hence I put together this app to solve these issues. A reason that I did not use existing apps was that I wanted the application running on my laptop to be coded in python (this is where I do most of my CV work). This also allowed me to learn android app development.
