Traditional feedback design is not applicable. The docking problem as such is well defined, but observe that it is he pose of he in the coordinates as lun~ownl the(More)
– The use of cameras in surveillance is increasing in the last years due to the low cost of the sensor and the requirement by surveillance in public places. However, the manual analysis of this data is impracticable. Thus, automatic and robust methods to processing this high quantity of data are required. This paper proposes a framework to address this(More)
Consider a robot to measure or operate on man made objects randomly located in the workspace. The optronic sensing onboard the robot are a scanning range measuring time-of-flight laser and a CCD camera. The goal of this paper is to give explicit covariance matrices for the extracted geometric primitives in the surrounding workspace. Emphasis is on(More)
