Polar Scan Matching is one of the methods of point to point scan matching for Simultaneous Localization and Mapping Application. It works in the original laser polar coordinate system and therefore eliminates the need for an expensive correspondence search as in other scan matching methods by using the matching bearing association rule. However, most of the low-cost laser range finders availabl...

This paper approaches detection and tracking of an aero-modelling helicopter with a laser range-finder. The sensing device can complement vision for aerial vehicle control in operations such as landing or taking off from the ground. To this end, a conventional 2D laser scanner has been adapted for 3D operation by means of a motorized base. First experimental results are presented for a small-sc...

In a self-mixing type laser range finder the current of the laser is modulated with a triangle wave to produce a range of optical frequencies. However, the electrical signal does not produce a perfect linear sweep in optical frequency due to thermal and other effects in the laser. This leads to errors in the accuracy and resolution of the range finder. In this paper, we describe and implement a...

This article discusses ways of measuring accuracy of a laser range finder (LRF) using a specially designed calibration cube (with 3D calibration marks) in the context of a particular application (i.e., measuring volumes). We also compare (by means of experiments) two alternative volume estimation methods.

The paper deals with the navigation system of a hybrid service robot intended for outdoor applications. The system uses different navigation sensors depending the current situation and task being done. The main sensors are laser range finder, GPS and heading gyro.
