How do I install Picamera on Raspberry Pi?
1. Installation
- 1.1. Raspbian installation. If you are using the Raspbian distro, you probably have picamera installed by default.
- 1.2. Alternate distro installation. On distributions other than Raspbian, it is probably simplest to install system wide using Python’s pip tool:
- 1.3. Firmware upgrades.

Is OpenCV good for image processing on a Raspberry Pi?
A nyone who has dealt with image processing in relation to the Raspberry Pi will sooner or later come across the OpenCV library. It provides many very useful features such as face recognition, the creation of depth maps (stereo vision, optical flow), text recognition or even for machine learning.
How long does it take to install OpenCV on Raspberry Pi?
Even on a Raspberry Pi B + compiling takes about 6 times as long, with a Pi 2 in total “only” takes about an hour. First of all, we update the package lists: A reboot is necessary if it has been updated. Then you can install all the important tools and libraries needed for OpenCV (installation takes a few minutes).
What is the difference between image processing and computer vision (CV)?
Make no mistake – we’ll discuss these two terms and how they relate. Both the Image Processing algorithm and the Computer Vision (CV) algorithm take pictures as input; however, in image processing, the output is also an image, whereas in the computer vision output there can be some features/information about the image.
How do I read and display an image on a pi?
Let’s first go through each function used to read, display and save an image. Then, we can write our code so that our program uses a Pi camera to detect faces, creates a rectangle around the detected faces, and snaps a picture. The function used to read an image is cv2.imread (). This function takes two arguments.
