Virtual camera based a novel calibration without modeling
, 2007 Usually, the camera calibration and distortion correction are both considered as procedures with two steps: modeling, and then solving the parameters. In this paper, we introduced a virtual camera into camera calibration and presented a novel method for ...

Mathematical models for geometric calibration of a hyperemispheric camera for planetary exploration [PDF]
, 2023 openHyperemispheric lenses belong to the ultra-wide field-of-view optical objectives. The lens considered was firstly introduced in 2018. Its field of view is 360° on the azimuth and 135° for the off-boresight angle.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

A planar homography estimation method for camera calibration
, 2003 More and more calibration methods are proposed based on planar homography. However, result accuracy of intrinsic parameters depends closely on homography estimation, which may be sensitive to noise. In this paper, a planar homography estimation method is

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption
Advanced Materials, EarlyView.A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes
Advanced Materials, EarlyView.Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...
