Multi spectral imaging analysis system imaging brightness meter

1、 Product Description and Technical Characteristics of Multi Spectral Imaging Analysis System Imaging Brightness Meter

Multispectral imaging（Multispectral Imaging, MSI）It is a method of simultaneously capturing the reflection or reflection of an object in multiple discrete spectral bands (wavelength ranges)againstThe technology of shooting information. It transcends the limitations of visible light (red, green, blue) to a wider spectral range (such as near-infrared, shortwave infrared, etc.), revealing the properties of objects at specific wavelengths“spectral characteristics”

Main testing parameters:

1Stereoscopic spatial spectral distribution

2RadiancemW/(cm²·sr·µm)

3Spectral indexNDVI

4originalDNreflectance

5Specific spectral features

Multi spectral imaging analysis system imaging brightness meterNew color detection algorithm with multispectral mode, utilizing high-speed black and white cameras 8Band light source or12A color filter, compared to traditional color cameras（RGB）Significant improvement in color recognition ability has been achieved. It can also easily distinguish subtle color differences.

3Spectral data Each pixel has a spectral dataForm a system that includes spatial and spectral information“data cube”This cube has two spatial dimensions（X，Y）And a spectral dimension

4、Customizable bands: The band position and width can be selected and optimized according to specific application requirements (such as bands specifically designed for vegetation health, mineral identification, or moisture detection).

5、Information Enhancement: By combining information from multiple bands, it is possible to highlight the human eye or monochrome/Features and differences that cannot be seen by a three color camera.

6Quantitative analysis: Provide the radiation values of each pixel in different frequency bands, which can be used to calculate various spectral indices and perform quantitative analysis.
