Please - can anyone explain to me in simple terms what "3d object recognition" is?

Question

Please, I have a job interview this week, and I want to be able to calmly explain this subject without getting confused. Thanks in advance !

Answer 1

"In computer vision, 3D single object recognition involves recognizing and determining the pose of user-chosen 3D object in a photograph or range scan. Typically, an example of the object to be recognized is presented to a vision system in a controlled environment, and then for an arbitrary input such as a video stream, the system locates the previously presented object"

I copied and pasted this from Wikipedia The Free Encyclopedia.
