The pictures acquired in near-infrared spectrum are divided into 7 sets, while each set contains 21. No additional lighting was required therefore we did not use flash light. The scene was lit with Fomei photographic lights and softboxes. We are aware of rather coarse step, but since we are more interested in images in NIR and TH spectrum we did not strive to refine the step. We moved manually the focusing ring in 5 mm steps. The images in the database of images in the visual spectrum were acquired using Nikon D80 camera with 50 mm f/1.8D AF Nikkor lens. There are included these objects (see the picture below): headphones, keyboard, keys, loudspeaker, mixer, sunglasses and guitar. The pictures acquired in visible spectrum are divided into 7 sets, while each set contains 12. Each subject is captured in a different focus position so that the database can be used for a development of auto-focus algorithms. This database consists of 7 objects acquired in visible, near-infrared and thermal spectrum. In case of any publications based on this database please cite a paper mentioned above. Interest Points as a Focus Measure in Multi-Spectral Imaging. It is possible to download the database here. With the new COBRA MultiSpec options, ProPhotonix is providing a high-performance, reliable and accessible solution for a wide range of multispectral and hyperspectral imaging applications."įor more information, visit. Simon Stanley, Director of Technology at ProPhotonix (IRL), said "As multispectral technologies have advanced and hardware costs have reduced, we are seeing rapid growth in the number and range of applications that can be addressed by this innovative imaging technology. COBRA MultiSpec is modular and is available in any length up to 5 meters. In addition, COBRA MultiSpec offers field adjustable optics allowing users to select the optimum lens position for its application. Custom lights can be developed in configurations of up to twelve wavelengths from 365nm –1650nm.ĬOBRA MultiSpec is built on the established, compact COBRA Slim platform and utilizes Chip-on-Board LED technology to ensure extreme brightness and excellent uniformity. RGB-IR (855nm) and RGB-White ( 3500K) COBRA MultiSpec lights are now available as standard, offering ideal solutions for a wide variety of multispectral and hyperspectral imaging applications including food sorting and currency inspection. For high speed image acquisition, the platform's exceptional strobe capability can be configured to pulse all four strobe lines either simultaneously or sequentially with a combined delay and response time of less than one micro second (1μs). Discrete control of each wavelength allows users to select the optimum wavelength balancing and relative intensities specific to the application needs. Precise control of the light via its user-friendly GUI allows system designers to easily fine tune the performance of their system. A new Graphical User-Interface (GUI) is also released with these two new standard configurations.ĬOBRA MultiSpec delivers multispectral tunable illumination allowing users to optimize the spectrum to maximize contrast, compensate for camera sensitivity and deliver clearer, higher resolution images for increased accuracy and speed. 8, 2020 /PRNewswire-PRWeb/ - ProPhotonix Limited, ((London Stock Exchange - AIM: PPIX, OTC: STKR), a designer and manufacturer of LED illumination systems and laser diode modules with operations in Ireland and the United Kingdom, is pleased to announce the addition of two new standard configurations to its COBRATM MultiSpec LED line light RGB-IR (855nm) and RGB-White multispectral lights.
