Most research on the visual servoing of mobile manipulators used the assumption that the depth information is already known. In this paper, a visual servoing scheme without the prior knowledge of depth is proposed to regulate a mobile manipulator to a desired pose at eye-to-hand setup. To deal with the nonholonomic constraint of wheeled mobile platform, the Jacobian matrix was combined with the depth-independent...
Motion estimation for an unknown parameters stereo camera rig is an important topic in the study of computer vision. This paper have proposed a method based on Euclidean reconstruction. Firstly, some feature points are extracted and matched. Then, they are reconstructed into the points in the 3D coordinates up to a scale, which is the length of the baseline. The unknown focal length is the key parameter...
This paper presents near-field localization of unintended emitting radio-controlled (RC) sources in a colored noise environment using a uniform linear array antenna. Existing localization methods for RC devices perform satisfactorily under white noise, but they ignore multipath fading or correlation among the sources. Therefore, a suite of novel schemes, referred to as 2-D multiple signal classification...
T-/pi- unstiffened Vierendeel connections in SHS sections loaded by axial and shear forces have been studied by nonlinear finite element method and uniform design approach. The influence of cross-sectional dimensions of members, the segmental length and the height of a Vierendeel truss were considered. Analysis shows that the cross-sectional dimensions of members exert a significant influence on the...
The recent nonlocal means filter (NLM) exhibits exciting performance for image or video denoising. However, the estimation of NLM is biased and tends to keep the value of noise. In the process of NLM, the target pixel (the pixel being processed) is involved in patch distance measuring, which, in turn, controls the restoration of the target pixel. Such design makes the estimation of the target pixel...
