Abstract

We propose a method of reversible digital watermark for point cloud data which is measured by a laser scanner on an aircraft. The proposed method performs confidential communications by embedding a bit string to the height of point cloud data, and is added points equal to the number of the bits. We verify the processing time of the proposed method through experiments with point cloud data.
