Simple and convenient robot hand-eye calibrating system and calibrating method

The invention provides a simple and convenient robot hand-eye calibrating system, which is suitable for an industrial robot. The simple and convenient robot hand-eye calibrating system comprises three-dimensional scanning equipment, a standard piece, a probe, a robot demonstrator and a measurement processor; the robot demonstrator is used for controlling an industrial robot; one end of the probe is connected to the tail end of a mechanical arm of the industrial robot; the needle tip at the other end of the mechanical arm of the industrial robot is a free end; the three-dimensional scanning equipment is connected to the measurement processor; the three-dimensional scanning equipment is used for scanning the standard piece to acquire corresponding three-dimensional point cloud data; the measurement processor can communicate with the robot demonstrator; the standard piece is arranged at the position where the probe can touch and the three-dimensional scanning equipment can scan; and the standard piece is at least provided with a vertex and two perpendicular edges that extend from the vertex, and is used for establishing a workpiece coordinate system of the standard piece under a basecoordinate system of the robot. The invention further provides a simple and convenient robot hand-eye calibrating method. The simple and convenient robot hand-eye calibrating system and calibrating method are easy to operate and high in precision.
