The optical design of multispectral camera
SPIE Proceedings, 2013According to the technical requirements of multi-spectral camera, using telecentric of TMA system, to meet the low distortion request of surveying and mapping. Considering factors, such as processing, assembly and adjustment, spherical surface shape is designed for the second mirror to ensure the fabrication reliability. The image quality is excellent,

Multispectral imaging with a modified DSLR camera
2016 International Symposium on Electronics and Smart Devices (ISESD), 2016This paper describes a multispectral imaging system using a Canon EOS 1000D camera, photographic lenses, and a dispersive element. The system consists of three subsystems: a PVC holder to arrange the optical devices that can be connected to the camera, an acrylic frame to support the position of the PVC holder, and expectation maximization algorithm to

Lightweight Multispectral Camera Calibration for Photogrammetric Applications
2018 9th IEEE Control and System Graduate Research Colloquium (ICSGRC), 2018The recent development of lightweight and small multispectral cameras has allowed the multispectral imagery acquired from either drone or terrestrial platform. A variety of multispectral sensors in the market are mostly designed for agriculture applications, nevertheless, gives benefits to different field such as cultural heritage which recording and ...

Combining images captured from a multispectral camera
2018 International Interdisciplinary PhD Workshop (IIPhDW), 2018This article discusses multispectral imaging that is based on capturing image data at specific wavelengths across the electromagnetic spectrum. Panchromatic images were captured by a RedEdge camera. This camera features global shutters for distortion-free images, including narrowband red, green, and blue bands for RGB color images that when processed ...

MADCam: The multispectral active decomposition camera [PDF]
, 2001 A real-time spectral decomposition of streaming three-band image data is obtained by applying linear transformations. The Principal Components (PC), the Maximum Autocorrelation Factors (MAF), and the Maximum Noise Fraction (MNF) transforms are applied. In the presented case study the PC transform appears to provide the best result for separating signal

A tiny VIS-NIR snapshot multispectral camera
SPIE Proceedings, 2015Spectral imaging can reveal a lot of hidden details about the world around us, but is currently confined to laboratory environments due to the need for complex, costly and bulky cameras. Imec has developed a unique spectral sensor concept in which the spectral unit is monolithically integrated on top of a standard CMOS image sensor at wafer level ...
