1.1. About HRVision 3D-Stereo

 

HRVision 3D-Stereo is a PC-based vision software for the robots and Hi4a/Hi5/Hi5a controllers of Hyundai Robotics to measure the 3D position/posture of a car body.3

 

HRVision 3D-Stereo provides color graphic operating buttons and an intuitive user interface for easy user operation. Applying a pattern recognition method that uses autoexposure calibration, multiple pattern registration, and geometric shape information, this software makes it possible to perform pattern recognition rapidly and accurately even in an environment where the illumination condition unstable.

 

By measuring three or more feature points that exist on a workpiece, this software can measure the 3D position/posture of the workpiece. It prevents vision measurement errors that could occur due to the false recognition of a feature point.

 

In addition, with Hyundai Robotics robot controller data communication protocols embedded, any operator of an Hyundai Robotics robot can use the vision system and the robot system by linking them easily without problem.

 

HRVision 3D-Stereo is an optimal tool that can perform measurement of the 3D position/posture of the car body by using an Hyundai Robotics robot.

 

HRVision 3D-Stereo provides the following convenient functions.

 

Simple operation	You can set and operate the vision system easily by using the operating button.
Auto camera calibration	This function is provided to perform auto stereo camera calibration by using a calibration plate.
3D position/posture measurement	It is possible to acquire the 3D position/posture of a workpiece based on the common coordinate system by measuring the four positions acquired from one stereo camera.
Hand-eye structure application	It is possible to estimate the 3D position/posture through the acquisition of the images from multiple time points by changing the position of the robot if the 3D position/posture of a workpiece cannot be measured.
Exposure calibration	This function makes it possible to perform pattern recognition robustly despite the variation in illumination of the surrounding environment by providing some functions such as autoexposure calibration and user-designated exposure setting.
Geometric pattern score	By executing the pattern score by using the geometric shape of the workpiece, you can execute the pattern recognition work strong to environmental changes.
Ellipse fitting	If there is a circular feature point with the workpiece, it is possible to enhance the measurement accuracy of the 3D position/posture by applying the ellipse fitting method.
Tool function	It is easy to set camera calibration, pattern registration, Reference car body registration, communication setting, various data managing by using each functional tool. Additionally, with the data communication protocol installed for Hyundai Robot controller, the interface with the Hyundai Robot is simple.
Monitoring function	You can monitor process sequence, communication sequence with Hyundai Robot, pattern recognition result etc, and manage the error history and data history. Additionally, you can save the image of the time of the error.
