Building Consistent Laser Scan Maps

The paper presents an approach to generate consistent maps in real-time using a laser range sensor. Its application scenario is the Bremen Autonomous Wheelchair “Rolland” that is developed as an autonomous transport vehicle for hospitals. The paper consists of two parts: in the first one, a laser scan matching method is presented that in several aspects improves an algorithm originally proposed...

Evaluation and Optimization of Laser Scan Data

The digitalization of objects from the real world is of great importance, e. g., in many multimedia applications, in 3D computer graphics, and in industrial measurement. In particular, methods of optical measurement are frequently used in this context. This type of 3D scanning yields a point cloud that may contain errors due to system specific characteristics. Considering the example of an opti...

Online Triangulation of Laser-Scan Data

Hand-held laser scanners are used massively in industry for reverse engineering and quality measurements. In this process, it is difficult for the human operator to scan the target object completely and uniformly. Therefore, an interactive triangulation of the scanned points can assist the operator in this task. Our method computes a triangulation of the point stream generated by the laser scan...

CAD-based Laser Scan Planning System

In this research, we propose an automated measuring system for a complex freeform surface. In order to automate a measuring process, appropriate hardware system as well as software modules are required. The hardware system consists of a laser scanning device and setup fixtures that can provide proper location and orientation. The software modules generate optimal scan plans and the scanning ope...
