Paper Abstract

At last year, we have been developing 3D scanning LIDAR designated as KIDAR-B25, which features the 3D scanning structure based on an optically and mechanically coupled instrument. In contrast with previous scanning LIDARs, vertical scanning is realized using two stepping motors synchronized with movement and moves in a spiral. From the results of outdoor experiments conducted last year to evaluate and measure the LIDAR performance and stability, we identified some limitations and problems that should be resolved. In the first instance, the samples per second are inefficient for use in detection, object clustering, and classification. In addition, the accuracy and precision of distance at every point is seriously affected by the reflectance and distance of the target. Therefore, we have focused on improving the 3D LIDAR range finding performance, speed of measurement, and stability regardless of environmental variation. Toward the realization of these goals, in this paper, we deal with two improvements compared with previous 3D LIDAR.
