Information Centric Networking (ICN) had merits in terms of mobility, security, power consumption and network traffic. When a large-scale disaster occurred, the current communication system might be fragile server based service unavailable due to damages, congestions, failure, etc. In this paper, we proposed an ICN Disaster Sharing Service (DISS) [1], [2] system. DISS could provide robust information sharing service. Users publish as content message with help our DISS. addition, by utilizing...
We propose a novel method to model and fabricate shapes using small set of specified discrete equivalence classes triangles. The core our modeling technique is fabrication-error-driven remeshing algorithm. Given triangle template triangle, which are coplanar have one-to-one corresponding vertices, we define their similarity error from manufacturing point view as follows: the minimizer maximum three distances between pair vertices concerning rigid transformation. To compute error, convert it...
Accurate camera calibration is necessary in photogrammetry systems. While traditional methods need precise pattern, this paper introduces a high-accuracy self-calibration method that doesn’t any metric information of the scene. The proposed combines epipolar geometry and bundle adjustment, both intrinsic extrinsic parameters are obtained. Synthetic data as well real have been used to test method, simulation result shows mean absolute relative errors focal lengths principal point about 4.5e-4...
Abstract We propose a novel topology optimization method to efficiently minimize the maximum compliance for high‐resolution model bearing uncertain external loads. Central this approach is modified power that can quickly compute eigenvalue evaluate worst‐case compliance, enabling our be suitable large‐scale optimization. After obtaining we use adjoint variable perform sensitivity analysis updating density variables. By iteratively computing performing analysis, and variables, algorithm...
Image registration is an important research content in image processing technology. Aiming at the problem that traditional methods are difficult to accurately register low-texture images, this paper proposes a high-precision algorithm based online segment features. For case of wrong match, using RANSAC random consistent sampling when searching for transformation model, and then iterate nearest points through ICP transform parameters further accurately. From experimental results, method...
Despite the fundamental diffraction limit of optical microscopy, we previously established that three-dimensional (3-D) subdiffraction-scale refractive-index (RI) fluctuations internal to a linear, label-free dielectric medium can be detected in far zone with spectroscopic microscopy (Cherkezyan et al., PRL 111, 033903 (2013)). However, our prior work, air-medium interface was assumed smooth plane.
To determine the relative pose between an object and a single camera using correspondences 3D feature points of their corresponding 2D projections in image, this paper proposes target's measurement algorithm based on bundle adjustment method. This iterative can be divided into two steps: first, reliable initial is computed by only three non-collinear points; second, optimal rotation translation matrix target estimated Experiments simulated data real show that method get high precision with...
The paper proposed a large field of view (FOV) measurement with calibrating the camera and measuring simultaneously. In measurement, whole FOV was divided into several smaller ones overlapping areas between each other. should contain at least 4 noncollinear feature points in for computing external parameters control one them to start calculation. To obtain FOV, 2 images (or more) small fields needed be taken from different angles. process calculation, theoretical values were used as initial...
Abstract In this study, we propose the possibility of generating several parallel and independent random bitstreams from time‐varying optical emission spectra an atmospheric pressure air microplasma system. This is achieved by splitting plasma arc into discrete wavelengths using spectrometer then monitoring fluctuating intensities each wavelength as time series. As a proof concept, considered eight centered at 377.8, 389.1, 425.8, 591.4, 630.5, 673.0, 714.2, 776.4 nm corresponding to atomic...
