This invention relates to a method and apparatus for single camera three-dimensional vision guided robotics. It addresses the need for a method for calculating the 3D position of objects using only standard video camera equipment that is capable of providing the level of accuracy and repeatability required for vision guidance of robots as well as other applications requiring 3D positional information of objects.
The method for three-dimensional handling of an object by a robot using a tool and one camera mounted on the robot end-effector is disclosed in which object features or landmarks are used to calculate the three-dimensional pose of the object. The process is performed in three main steps: calibration of the camera; selection of the features on the object; finding the three-dimensional pose of the object and using this information to guide the robot to the object to perform any operations, e.g. handling, cutting, etc.
