Paper Title
Basic Experiment of Lidar Sensor Measurement Directional Instability For Moving and Vibrating Object
Abstract
The purpose of this paper is to develop a new scan matching method for LiDAR SLAM. One of the problems in
scan matching is that as the amount of data increases, the computation time becomes enormous. Automated driving uses
large amounts of data for safety reasons, but this requires a high-performance PC in the vehicle. We therefore devised a
method that allows estimation with a smaller number of data while keeping safety. It is the Virtual LRF and the two-sided
search method. Virtual LRF is a method to extract only important data from map data by reproducing LRF on a PC. The
two-tailed search method is a method that aims to improve the accuracy of estimation by efficiently using data not
considered in the estimation by the ICP algorithm. New map data is generated in the Virtual LRF, and the matching process
is performed using the two-sided search method.
In the experiment, we simulated the rotational motion of the target object on a PC. We estimated each using the ICP and
two-tailed search method, and compared the effects on the estimation with and without the Virtual LRF. The graphs of the
evaluation function E (Fig. 6(b), 6(d), 7(b), and 7(d)) show that we succeeded in reducing the local minimums, which is a
major obstacle to estimation, three out of four times in this experiment In addition, there are fewer cases of extremely small
estimable areas when the map is changed than before. In the future, we will analyze the effects of the LRF in the case of
parallel shifts, and seek more effective ways to use the virtual LRF.
