Most sensor setups for onboard autonomous perception are composed of LiDARs and vision systems, as they provide complementary information that improves the reliability different algorithms necessary to obtain a robust scene understanding. However, effective use from sources requires an accurate calibration between sensors involved, which usually implies tedious burdensome process. We present me...

This paper presents a system for automating the time consuming task of manual colour calibration for a mobile robot. By converting a series of YUV images to HSI format and analysing histogram data it can be seen that there are distinct regions of colour space for each object colour class and that one dimension, hue, can be used to uniquely identify each colour class. Using an expectation maximi...

In this paper we approach the problem of insitu camera calibration using an auxiliary mobile color-depth camera. The calibration is based on image lines and the Direct Linear Transformation (DLT). Calibration includes intrinsic and extrinsic parameters, and radial distortion. Traditionally, camera calibration methods based on DLT combine 2D and 3D points. Using 2D image lines allows adding simp...
