Our new lighting technology, VISA-Method Lighting, has won the 1st Prize of the Vision Award 2016, the prize for applied imaging presented at the Vision show in Stuttgart. Machine Vision Lighting won for its revolutionary VISA-Method Lighting using the new lighting technology as a visual function beyond the Deep learning, Hyperspectral Imaging, Ultrafast 3D z-Inspection photography etc. It is the first time an innovation in lighting has been recognized in the award. V-ISA Method Lighting is just a technology that overturns conventional wisdom by focusing on uniform irradiation light and optimized illumination; it is now recognized by the world as a valid, new method of lighting. VISA-Method Lighting is able to give uniform irradiation solid angle of light irrespective of distance from an object and to get the 3D information of the surface by single imaging of the normal camera and lens without any scanning and any image processing. We, Machine Vision Lighting Inc., founded in 2014 by Shigeki Masumura. We provide the new lighting technology as a visual function for all machine vision systems using an image processing. V-ISA stands for Variable Irradiation Solid Angle. V-ISA Method Lighting is a method of lighting that enables the range of the angle of irradiation of light on an object—or in other words, the irradiation solid angle—to be freely and uniformly controlled, for all points on the object. The surface of object, a metal or a specular surface, can be seen by the conventional coaxial lighting. But, when the same object is lit with V-ISA Lighting, details that were difficult to pick up, like the depressions in the object surface, tiny scratches, and dents, can be viewed easily, accurately, and reliably. In addition, as you can see here, another capability is that you can freely control the threshold value that expresses surface inclination as grayscale levels. Here is yet another possibility. If we use a concentric circular RGB multilayered irradiation solid angle, the surface inclination can be converted into a color gradation, independent of the direction of inclination. As shown here, the same color means the same inclination. At this exhibition, we are showing off our new series of V-ISA Lighting systems, which has a newly designed lens system and irradiation solid angle shaping unit. As this image demonstrates, these advancements enable object colors to be displayed with even greater precision. Using a radial RGB multilayered irradiation solid angle by converting the surface inclinations at all angles into a color gradation, V-ISA Method Lighting is capable of capturing complete 3D images in one shot, without the need for scanning. With this technique, it is possible to accurately identify only the surface inclinations of any particular angle, and in any particular direction. With V-ISA Method Lighitng, even if there is surface inclination in different directions, images that clearly show all the surfaces with the same angle of inclination as the same color can be captured. In addition all the directions and the inclinations of an object can be expressed in terms of all different color gradations. At the heart of our new V-ISA series are new optical components for shaping the multilayered irradiation solid angle. By significantly improving the optical system, we have made it possible to capture 3D information from glossy surfaces in a variety of useful ways, in one shot.
