Features

Intrinsic Camera Calibration

Estimation of intrinsic camera parameters from multiple images of a calibration target. The target recognition and the extraction of the calibration points with subpixel accuracy are carried out automatically.
Use cases: Lens distortion correction, 3D projection

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

Extrinsic Stereo 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, sensor fusion

Manhattan World Calibration

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

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

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 using a Gray code pattern. The tutorial also shows how to estimate extrinsic parameters of a 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.
