Bin Picking Problem
the basis of perspective.Almost everyone,however,has had the experience
of being fooled when looking at a scene with one eye covered or blocked.
A nearby pole and a distant tower might seem to be near each other,
when in fact they are hundreds of meters apart.
In a robot,binocular vision requires a sophisticated microprocessor.The
inferences that humans make, based on what the two eyes see, are exceed-
ingly complicated. The illustration shows the basic concept for binocular
machine vision.

Binocular machine vision

Of primary importance for good binocular robot vision are the following:
• High-resolution visual sensors
• A sophisticated robot controller
• Programming in which the robot acts on commands, based on what
it sees

BIN PICKING PROBLEM
A bin picking problem is a challenge presented to a robotic vision system
in which the machine must choose a specific object from a group of ob-
jects. Basic machine vision systems can see only the outlines of objects;
depth perception is lacking. As viewed from different angles by such a
vision system, the appearance of an object can vary dramatically.
