Inexpensive multispectral imaging device
Instrumentation Science & Technology, 2022 Multi/hyperspectral imaging is an important technique to obtain color data and spectral monitoring. It is a precise remote sensing technique that includes two or more bands in the visible and invisible spectrum. This study demonstrates the design and construction of a low-cost, multispectral imaging system using a single linear array sensor and a ...

Multimodal Mixed Reality for In‐Field Visualization of RGB‐Based Vegetation Indices
Advanced Intelligent Systems, EarlyView.Evaluating crop physiological health in field environments remains constrained by offline data processing or static 2D displays, limiting real‐time spatial interpretation. This paper presents a novel mixed reality framework that calculates, normalizes, and visualizes 20 RGB‐based vegetation indices directly in agricultural fields using consumer‐grade ...
