A Machine Learning and Point Cloud Processing based Approach for Object Detection and Pose Estimation: Design, Implementation, and Validation
Nylund, Simon Erik; Bringager, Fredrik (Master thesis, 2022)This thesis presents an automatic forklift approach for lifting and handling pallets. The project more specifically develops a solution for autonomous object detection and pose estimation by Machine Learning (ML), point ... -
Autonomous mooring towards autonomous maritime navigation and offshore operations
Jha, Ajit; Subedi, Dipendra; Løvsland, Per-Ove; Tyapin, Ilya; Cenkeramaddi, Linga Reddy; Beferull-Lozano, Baltasar; Hovland, Geir (Chapter, 2020)Bollard is a vital component of mooring system. It is the anchor point for mooring ropes to be fixed in order to secure the vessel or ship. An algorithm that translates the segmented mask of bollard output from masked R-CNN ... -
Bollard Segmentation and Position Estimation From Lidar Point Cloud for Autonomous Mooring
Jindal, Mehak; Jha, Ajit; Cenkeramaddi, Linga Reddy (Peer reviewed; Journal article, 2021)This article presents a computer-aided object detection and localization method from lidar 3-D point cloud data. This topic of interest is in the framework of autonomous mooring, where the ship is tied to the rigid structure ... -
Camera-LiDAR Data Fusion for Autonomous Mooring Operation
Subedi, Dipendra; Jha, Ajit; Tyapin, Ilya; Hovland, Geir (Journal article; Peer reviewed, 2020)The use of camera and LiDAR sensors to sense the environment has gained increasing popularity in robotics. Individual sensors, such as cameras and LiDARs, fail to meet the growing challenges in complex autonomous systems. ... -

Current Modulation Induced Stability in Laser Diode Under High Optical Feedback Strength
Jha, Ajit; Shah, Manoj K.; Jha, Sachin; Cenkeramaddi, Linga Reddy; Royo, Santiago (Peer reviewed; Journal article, 2021)The back-reflection of emitted laser beam (optical feedback, also know as selfmixing) from various external interfaces are sufficient to cause instability, and prohibiting its use in various fields such as communication, ... -
Edge-Distributed Fusion of Camera-LiDAR for Robust Moving Object Localization
Andrade, José Amendola Netto; Dayal, Aveen; Cenkeramaddi, Linga Reddy; Jha, Ajit (Peer reviewed; Journal article, 2023)Object localization plays a crucial role in computational perception, enabling applications ranging from surveillance to autonomous navigation. This can be leveraged by fusing data from cameras and LiDARs (Light Detection ... -
Generalized multi-cavity laser self-mixing interferometry based on scattering theory
Jha, Ajit; Cenkeramaddi, Linga Reddy; Royo, Santiago (Peer reviewed; Journal article, 2023)We present a generalized mathematical model and algorithm for the multi-cavity self-mixing phenomenon based on scattering theory. Scattering theory, which is extensively used for travelling wave is exploited to demonstrate ... -
