In the geological exploration of the Adit, the texture, section, joint and other rock structural information are important factors to determine the stability of the Adit. Therefore, the collection and analysis of rock data information are the premise work and the key process of the safe production. Faced with the actual requirements of Adit 3D reconstruction, an automatic 3D reconstruction system...
To reduce the size and requirement of DC biasing capacity of saturated-core fault current limiter, a novel hybrid compact saturated-core fault current limiter (HCFCL) is proposed by this paper. The three-limb structure with Permanent magnets can reduce the size and DC biasing capacity. Firstly, the principle of HCFCL is introduced. To validate the performance, various FEA simulations with the 3D nonlinear...
An accurate two-dimensional-three-dimensional (2D-3D) image registration method is introduced in this paper, which is used in image-guided surgery to detect and correct patient movement during image-guided intervention treatment. In this paper, we decompose a 3D rigid transformation in the 3D patient coordinate into in-plane transformations and out-of-plane rotations in two orthogonal 2D projections,...
Passive source location attracts a growing interest due to its usefulness in various applications such as wireless communications, microphone arrays, sensor networks and so on. This paper combines the time differences of arrival (TDOA) and gain ratios of arrival (GROA) techniques to present a novel dual-station source location method of a known altitude object in 3D space. The closed form solution...
A multiview stereo video FGS (Fine Granular Scalability) scalable scheme is presented in this paper. The similarity among adjacent views is fully utilized, A tradeoff scheme is presented in order to adapt to different demands of Quality First (QF) and View First (VF) of the decoder. The scheme is composed of three cases: I, P, B frame. The middle view is encoded as the basic layer, while the other...
Multiview stereo image composition mainly depends on the type of the multiview stereo display device. Currently, multiview LCD optical plate autostereoscopic display device is common in the art, while the composition method is limited. A new general multiview LCD stereo image composition method is proposed in this paper based on the optical plate LCD stereo display device. The proposed method mainly...
