The Photogrammetric Record, Volume 37, Issue 179, Page 260-284, September 2022., 2022 Zhang et al. propose an improved multi‐task pointwise network to simultaneously segment instances (that is, individual roof planes) and semantics (that is, groups of roof planes with similar geometric shapes) in point clouds. A new roof data‐set (called RoofNTNU) is established by taking standard airborne laser scanning (ALS) point clouds as training ...

Exploiting Light Directionality for Image‐Based 3D Reconstruction of Non‐Collaborative Surfaces
The Photogrammetric Record, Volume 37, Issue 177, Page 111-138, March 2022., 2022 The paper investigates the effect of light directionality and the fusion of multiple images to improve the quality of photogrammetric 3D reconstruction of complex surfaces (textureless and shiny). We present an image capturing system that utilizes multiple light sources to highlight roughness which is not visible in traditional diffuse images ...

Automated calibration of smartphone cameras for 3D reconstruction of mechanical pipes
The Photogrammetric Record, Volume 36, Issue 174, Page 124-146, June 2021., 2021 A framework for the laboratory calibration of smartphone cameras is proposed, introducing new methods for: (i) matching calibration targets; (ii) adjusting target eccentricity error without object‐space target information; and (iii) improving the calibration using a free‐network self‐calibrating bundle adjustment.

IET Communications, Volume 15, Issue 2, Page 279-288, 17 January 2021., 2021 Abstract Transmission of three‐dimensional (3D) orthogonal frequency division multiplexing (OFDM) signals over red, green and blue (RGB) visible light communication (VLC) systems is proposed and experimentally validated. The novel 3D modulation format aims to overcome the different luminous response of RGB light‐emitting diodes at the same driving ...
