Features

Complete user manual

Comprehensive presentation of the geometric calibration problem,
camera modelling and the solution of different calibration problems with 3D-EasyCalib.
The complete, detailed programme documentation and process description is part of every licensed programme version.

Intrinsic Camera Calibration

Estimation of intrinsic camera parameters from multiple images of a calibration target. The detection of a target and the extraction of the calibration points with sub-pixel accuracy are carried out automatically in the case of typical chessboard targets or targets with ArUco* markers. The inclusion of externally determined target coordinates can be done easily.

Use cases: Lens distortion correction, 3D projection


*Possible from version number >2.10.15.
Licence holders are upgraded free of charge.

Camera-Projector Calibration

Robust and accurate projector calibration with a complementary gray code sequence. This pattern can be generated for any projector resolution and robustly decoded in the camera image.

Use cases: 3D structured light imaging, augmented reality projection

Hand-Eye Calibration

Compute a rigid transformation between a camera mounted on the robot actuator and the actuator itself by a fixed calibration target in your environment.

Use cases: bin picking

Manhattan World Calibration

The orientation and position of a camera is determined using a Manhattan world assumption without the use of calibration targets.

Extrinsic Stereo/Camera Pair Calibration

Determine the relative geometric orientation and position of two cameras to each other. Similar to intrinsic calibration, the targets and calibration points are recognized automatically. Intrinsic parameters can be computed during the extrinsic calibration process or input manually.

Use cases: depth sensing, 3D coordinate transformation, 3D-based sensor fusion

Tool-Flange and Robot-World Calibration

Compute geometric transformations between stationary cameras and robot bases as well as robot-tools or -flanges with calibration targets on the robot.

Use cases: robot-assisted inspection control, machine-human collaboration

Use cases

Intrinsic calibration of a KinectV2 IR camera. On the left side of the window is the list of calibration images. These are shown in color according to the size of the calibration error, from green (min error) to red (max error). In the middle is the image of a selected target pose with detected calibration points (circles) and the points computed according to the camera model (crosses). The color of the circles encodes the absolute difference between these points. The various target poses in the camera’s coordinate system are displayed on the right.

Extrinsic calibration of an imaging THz scanner (body scanner) and a monochrome camera for a depth-based sensor fusion. On the left is the image of the target taken with a standard camera and in the middle the image of the same target recorded with the THz camera. The 3D view on the right uses the camera coordinate systems to show the relative orientation and position of these two sensors to another as well as the different target poses.

User interface for the robot/world and tool/flange calibration. The left column shows the individual camera recordings with color-coded reprojection errors. In the column next to it, the TCP poses are marked according to the 3D error. A selected image is shown in the center and the components are shown in 3D on the right.

Demonstrator of a workstation for assembly processes at ZBS e. V. (left). The assembly worker’s actions are verified by tracking his hands with several cameras and comparing the information with an assembly process plan. The sensor system consists of a time-of-flight camera for person recognition, three active stereo cameras for component recognition and hand tracking, and a projector for augmentation. The illustration on the right shows the calibrated components of the assembly in the software front end of the 3D-EasyCalib™.

Steb-by-Step Tutorials WITH 3D-EASYCalib

Intrinsic Camera Calibration

This introductory tutorial shows how to intrinsically calibrate a camera. You will learn how to specify target detection parameters correctly and how to identify and remove outliers to achieve optimal calibration results.

Camera-Projector Calibration

Learn how to calibrate a projector (inverse camera) using a code pattern. The tutorial also shows how to estimate extrinsic parameters of a real camera and a projector.

Hand-Eye Calibration

In this tutorial, you will learn how to accurately estimate the rotation and translation of a camera mounted on a gripper with respect to the tool center point.

Extrinsic Stereo Calibration

This tutorial shows how to calibrate a camera pairing extrinsically. You will learn how to specify the parameters correctly, how to take the intrinsic calibration step into account and how to achieve optimum calibration results by iteratively analysing and adjusting the calibration data.

Manhattan World Calibration

A step-by-step tutorial is coming soon ...

Tool-Flange and Robot-World Calibration

If you are observing a robot with a static camera and want to estimate the position and orientation of the robot base coordinate system in relation to the camera, then follow this tutorial.
