3D-EasyCalib Kameraorientierung mit Manhattan-World-Annahme

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 program documentation and process description is part of every licensed program version.

Intrinsic Camera Calibration

Estimation of intrinsic camera parameters from multiple images of a calibration target. Detection of the calibration object and extraction of calibration points with sub-pixel accuracy are performed automatically for typical chessboard (with or without circular markers) or ChArUco* targets. Externally determined calibration point coordinates can also be imported .

Use cases: Lens distortion correction, 3D reconstruction

*Available from version 2.10.15. Existing licence holders receive a free upgrade for two years.

Hand-Eye Calibration

Compute a rigid transformation between a camera attached to the robot actuator and the actuator itself by a fixed calibration object in your environment.

Use cases: bin picking

Camera-Projector Calibration

Robust and accurate calibration of programmable projectors by usage of a camera.

Use cases: active 3D, augmented reality projection

Extrinsic Stereo/Camera Pair Calibration

Extends the intrinsic calibration functionality to determine the relative position and orientation of two cameras with respect to each other. Target detection and calibration point extraction are again performed automatically for typical chessboard (with or without circular markers) or ChArUco* targets. Intrinsic parameters can either be estimated jointly during the extrinsic calibration process or provided manually.

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

*Available from version 2.10.15. Existing licence holders receive a free upgrade for two years.

Tool-Flange and Robot-World Calibration

Compute geometric transformations between stationary cameras and robot bases as well as robot-tools or -flanges with calibration objects attached to the robot actuator.

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

Manhattan World Calibration

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

Own Use cases

Intrinsics calibration with 3D-EasyCalib using a chessboard target with circular markers.
Intrinsic calibration of a NIR camera. The left panel lists all images used for the calibration, with colours indicating the calibration error from green (small error) to red (large error). The centre panel shows the target detection for the selected image. Detected target corners are marked as circles, while the corresponding corner positions computed from the camera model (i.e. the calibration result) are marked as crosses. The colour of each circle encodes the absolute difference between these two points. The right panel displays the various target poses relative to the camera coordinate system.
Extrinsic calibration of an imaging THz scanner (body scanner) and a monochrome camera for depth-based sensor fusion. On the left is the image of the calibration target captured with a standard camera, and in the centre the image of the same target recorded with the THz camera. The 3D view on the right uses the camera coordinate system to illustrate the relative orientation and position of the two sensors with respect to each other, as well as the different target poses.

User interface (v. 2.10.15) for robot-to-world and tool-to-flange calibration. The left column shows the individual camera images with colour-coded reprojection errors. In the adjacent column, the TCP poses are colour-coded according to the 3D error. The selected image is displayed in the centre, and the calibration components are shown in 3D on the right.

Demonstrator of an assembly workstation at ZBS e. V. (left). The assembly worker's actions are verified by tracking their hands with multiple cameras and comparing the results against an assembly process plan. The sensor system consists of a time-of-flight camera for person detection, three active stereo cameras for component recognition and hand tracking, and a projector for augmented reality overlay. The illustration on the right shows the calibrated assembly components as displayed in the software frontend (v. 2.10.15) of 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 pair 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.

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.

Manhattan World Calibration

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

Troubleshooting & HowTo's

How do I update 3D-EasyCalib if I have a permanent license?

That is easy!

  1. Open File Explorer and navigate to \ProgramData\ZBS e.V\3D-EasyCalib\. Save your license file 3D-EasyCalib.bin.
  2. Uninstall the program and remove any remaining program files.
  3. Install the new version and replace the license file with your backup

The program starts with the error message „3D-EasyCalib was not installed properly. Please run the program as administrator once or reinstall it as administrator“.

The error message suggests that the program did not install correctly on your system, possibly due to issues with the rights to execute the program.

  1. Open File Explorer and navigate to \ProgramData\ZBS e.V\3D-EasyCalib\.
  2. Run the file lpregister410.exe as an administrator.

If the problem persists, send us an email.
