Autonomous navigation is an important field of research and, given the complexity of real
world environments, most of the systems rely on a complex perception system combining …

The fusion of data from different sensors often requires that an accurate geometric
transformation between the sensors is known. The procedure by which these …

Mobile platforms typically combine several data acquisition systems such as lasers, cameras
and inertial systems. However the geometrical combination of the different sensors requires …

This paper proposes a general approach to the problem of extrinsic calibration of multiple
sensors of varied modalities. This is of particular relevance for intelligent vehicles, which are …

Multiple two-dimensional laser rangefinders (LRFs) are applied in many applications like
mobile robotics, autonomous vehicles, and three-dimensional reconstruction. The extrinsic …

Laser rangefinders (LRFs) are widely used in autonomous systems for indoor positioning
and mobile map** through the simultaneous localization and map** (SLAM) approach …

Intelligent vehicles are complex systems which often accommodate several sensors of
different modalities. This paper proposes a general approach to the problem of extrinsic …

In this work we present an in-situ method to compute the calibration of two sensors, a LIDAR
(Light Detection and Ranging) and a spherical camera. Both sensors are used in urban …

The number of LIDAR sensors installed in robotic vehicles has been increasing, which is a
situation that reinforces the concern of sensor calibration. Most calibration systems rely on …

Masonry structures commonly composed of a large amount of bricks or stones. Making an
inventory of bricks in masonry walls is of great importance in the fields of building …
