I have read about the concept of stereo vision in several sources, but I would like to read the explanation in more simple language than scientists usually use. So, what is the stereo vision in brief?
Well, a human has 2 eyes, then why not to use 2 cameras in the artificial devices? This phrase can be used to prove the concept of stereo vision because the basics of stereo vision are the usage of 2 cameras to see the world. People have 2 eyes and our brain combines information from both of them to create a realistic reflection of the environment. The same is true for the stereo vision: information from 2 cameras, which are placed in the same horizontal plane, is merged to create a 3D view. Many preprocessing steps should be done to achieve these results, but they are out of the scope of my answer, you can just search for the stereo vision concept and learn it in more details if you have the desire to do this.
