As one of the most convenient and accurate biometrics technologies, iris recognition technology can acquire the clear iris image of individuals and is directly affected by the environment. This environmental constraint has also become a technical challenge for all parties involved in the iris recognition industry to break through. Even the most recent Fujifilish iris phones are also being suggested to be unlocked by using an alternative password or graphical unlocking feature in outdoor glare. Iris glare is difficult to identify two reasons: First, the rapid contraction of the pupil in glare, the iris segmentation becomes extremely difficult; Second, the sunlight near the infrared part of the light can easily saturate the image sensor, so that the iris image Signal-to-noise ratio is uncontrollable resulting in recognition failure.
Recently, Wuhan Hong Technology Co., Ltd. (hereinafter referred to Hong Technology) to obtain a breakthrough in solving this problem stage, Rainbow Technology team developed a special light algorithm and design a unique hood designed to achieve up to 100K LUX Strong iris recognition. The iris recognition terminal device based on this technology can realize fast and accurate identification in the direct sunlight all-weather environment.
According to the actual needs of customers, Rainbow Technology has further optimized its self-developed iris recognition algorithm. Algorithm-based optimization can effectively improve the recognition ease-of-use in bright light environment. At the same time, in order to create a relatively isolated outdoor identification environment and to adapt to higher direct sunlight intensity, Rainbow Technology is another way to add the patented shade to the existing terminal access control equipment to enhance the durability. Up to now, all kinds of terminal equipment under the company's product line have been fully registered in the normal light environment and glare recognition. Combined with the existing infrared fill light amblyopia environment recognition capabilities, Hong Technology various end products have been truly all-weather operations, greatly expanding the product range.
The second detention center in Wuhan City is the first user of Hong Technology Iris glare identification products. Currently, the detention center has established a huge database of criminals iris. On Sept. 21, at the detention center's request, Rainbow Technology installed an iris access control terminal device using the latest technology for the discharge of prisoners and the management of collective labor. After repeated use of testing, detention center staff said that the product experience is very good, light, dark and other environments can be achieved quickly and accurately identify.
Rainbow Technology's latest innovations can further expand the iris recognition product application scenarios and improve the user experience, is expected to lead the industry to develop new trends.
