Description
Very Compact Megapixel Multispectral Cameras
CMS4 megapixel multispectral cameras are specially designed to allow high integration of VIS/NIR multispectral systems. These lightweight (less than 170g) and very small footprint (52x62x40mm) cameras split the image into 8 spectral bands plus 1 B&W channel. Made by hybridization of a custom Bayer-like mosaic filter on a commercial 4.2 MPixel CMOS Sensor, they allow extracting the spectrum on each point of an image. SILIOS offers three different CMS4 cameras (CMS4-C, CMS4-V and CMS4-S) to address a wide spectrum of applications.

Software Development Kit (SDK) COLOR SHADES ® LAB
COLOR SHADES® LAB is the SDK for the CMS/CMS4 Series multispectral cameras. It allows 1) displaying the raw images, false color images, gray scale images or overlaid images with different indexation methods (such as “spectrum recognition”), 2) normalizing the spectral channels, 3) applying multispectral image corrections such as the crosstalk correction and 4) extracting the hypercubes.
COLOR SHADES® LAB runs with real time acquisition, but can also run with recorded single image or series of images (“replay mode”).
COLOR SHADES® LAB supports any of the CMS and CMS4 cameras (C, V or S) and recognizes each plugged one via its S/N number. The specific spectral data of the corresponding multispectral sensor are then used for spectral corrections and treatments.
COLOR SHADES® LAB is supplied for free with any purchased multispectral CMS/CMS4 camera.
