• Adaptive Structured Light with Scatter Correction for High-Precision Underwater 3D Measurements 

      Risholm, Petter; Kirkhus, Trine; Thielemann, Jens T; Thorstensen, Jostein Bruun (Peer reviewed; Journal article, 2019)
      : High-precision underwater 3D cameras are required to automate many of the traditional subsea inspection, maintenance and repair (IMR) operations. In this paper we introduce a novel multi-frequency phase stepping ...
    • Design tool for TOF and SL based 3D cameras 

      Bouquet, Grégory; Thorstensen, Jostein Bruun; Bakke, Kari Anne Hestnes; Risholm, Petter (Journal article; Peer reviewed, 2017)
      Active illumination 3D imaging systems based on Time-of-flight (TOF) and Structured Light (SL) projection are in rapid development, and are constantly finding new areas of application. In this paper, we present a theoretical ...
    • Real-time super-resolved 3D in turbid water using a fast range-gated CMOS camera 

      Risholm, Petter; Thorstensen, Jostein Bruun; Thielemann, Jens T; Kaspersen, Kristin; Tschudi, Jon; Yates, Chris; Softley, Chris; Abrosimov, Igor; Alexander, Jonathan; Haugholt, Karl Henrik (Journal article; Peer reviewed, 2018)
      We present a range-gated camera system designed for real-time (10 Hz) 3D estimation underwater. The system uses a fast-shutter CMOS sensor (1280×1024 1280×1024 ) customized to facilitate gating with 1.67 ns (18.8 cm in ...
