In this video lesson we learn how to track objects using OpenCV based on the HSV color space. In this lesson we just box the objects found, but in future lessons we will turn the servos back on and track the object of interest.

Here is the bracket/servo system, I suggest two sets.

Also I am suggesting two raspberry pi camera, version 2. I like the units below because they include the long cable.

This camera also has a cool little acrylic case, which is nice.

This is the other NVIDIA Jetson Xavier gear I am using.

Jetson Xavier NX Development kit:

You need a GOOD SD card:

Raspberry Pi Camera

Extra Long Cable for Raspberry Pi

Small plastic case/stand for Rpi Camera

Wireless Keyboard and Mouse

Western Digital SSD For the Jetson Xavier NX

If you are not ready for the Jetson Xavier NX, you can follow these lessons using a Jetson Nano, Available below:

You need a GOOD power supply:

You need a GOOD SD card:

I love this cool Acrylic case with fan:

Wireless Keyboard and Mouse that works with Jetson Nano:

I like to run with minimum wires, so I am running this wifi card, which works very well. If your budget is tight just use an Ethernet cable, as all my lessons will work with just an ethernet cable.

Finally, you can use either a Logitech C920 WEB cam or the Pi Cam. I am using both, but you need at least one camera working with the nano:
