Scene analysis (IMAGE)
Caption
Researchers have developed a new compact low-cost hyperspectral projector system that provides both depth information and hyperspectral images using a monochrome camera as the sensor. They used the new system to analyze a scene that contained a small red and green ramp alongside red and green candies of different sizes. Although the green color on the ramp and the green coating of the candy look quite the same to the human eye and a RGB camera, the system was able to clearly distinguish the two materials from the reconstructed spectra as well as measure the correct heights for all the objects.
