The Observer is a software for a face recognition and face tracking devices. The application is able to fully and reliably control the movement of the camera using two servomotors in any direction. The real-time recognition algorithm is provided by the optimized computer vision library OpenCV.

The entire software was developed with a performance in mind and all decisions were made to be perfectly compatible with low-end PCs (aiming to be runnable on minicomputers like Raspberry Pis).

The observer uses these technologies to run properly:

• Go v1.14
• Gobot v1.14.0
• GoCV v0.23.0
• OpenCV v4.3.0
• HaarCascade

Tested on Raspberry Pi 3 Model B+:

With go, opencv4, gocv and gobot installed, run this command to install executable file into your PATH:

$ go get github.com/chutommy/observer-rpi

OR

Download the source and run the install.sh file as a sudo user in the project root directory to install all dependencies and the Observer software (can take up to 15 minutes).

$ sudo ./install

Type ./observer -h or --help in a terminal to get more info about the observer command.
