It's really amazing what we can do using a simple combination of sensors and actuators. After all, these are the things that make robots what they are known for. There is a vast numbers of sensors available on the market today that we can use. We can put hundreds of sensors over a robot, but there is one thing that subsides the power of all other sensors. It's the camera. Sensors give us data about our physical environment, whereas the camera lets us see it. So, it is quite an important sensor to consider. In this chapter, we will go ahead and see how we can couple a camera to our Raspberry Pi and start computing with the image data that we get.
The following topics will be covered in this chapter:
- The basics of images
- Preparing Raspberry Pi for vision processing application
- Installing OpenCV
- Image recognition
