2D Targets for Laser Scanning

In terrestrial laser scanning, the question always arises of how to link the various scanner positions as precisely as possible so that a homogeneous point cloud is created.

When registering the individual scans, various methods/procedures of cloud-to-cloud or target point-oriented approaches can be applied.

In a small test, one of our working students investigated to what extent the code targets specified by FARO for the close range up to 6 m lead to better results than the use of the standard checkerboard or circle marks.

Conclusion: In the range up to 7 m, the code targets show better results than the previously used standard targets, i.e. for narrow areas such as staircases, they are a useful addition to the 2D and 3D targets.
