Predicts 2021, the global face recognition market is expected to reach $6.37 billion, according to the expected during the compound growth rate of 17.83%. China's market size and face recognition according to the current situation of development of face recognition industry, estimate the face recognition about the size of the market accounts for about 10% of the global market. 2010-2016, our country face recognition market scale increased year by year, the average annual compound growth rate of 27%. In 2016, our country face recognition industry market size is about 1.725 billion yuan, up 27.97% year on year, growth is up 4.64% from a year earlier. As China's online identity just need and user habits, face recognition application scenario will increase further, considering the security upgrade, online identity authentication as well as the application of Internet innovation factors, the size of the market is expected to more than forecast growth in the future. Holographic capture and in addition, the development of measurement technology, face recognition algorithm based on the holographic could make up for a 2 d projection effective identification information loss problem, to face rotation, shade, and extremely similar to the traditional difficulty has the very good solution, also gradually become another important development of face recognition technology route. In face recognition industry, enterprise's target customers include the government, enterprises and individuals three categories. Among them, the main products include in the field of government oriented security products, electronic government affairs, anti-terrorism products etc. Enterprise products mainly in the field of technology solutions, terminal products, etc.; Geared to the needs of individual customers to provide products mainly include social and mobile related products. With the improvement of the holographic face library and equipment cost is reduced, the holographic face technology will be more and more applied in various industries, has a huge market space. At present in the field of face recognition is still have a few core problem in the industry, in the use of holographic facial recognition system would have to greatly improve and solve.
  • Lighting problem: in the practical application of the traditional face recognition system, will be caused by the change of environmental light detected face image in different changes in dark. Error rate is bigger, recognition success rate is low.

    Using holographic recognition methods: light face recognition system based on 3 d structure WiMi since the depth of the research learning algorithm and the structure of 3 d optical depth structure light cameras. Fault tolerance rate can reach one over one million.
  • Gestures: attitude problem is also currently a technical difficulties of facial recognition technology. At present most face recognition algorithm mainly needle columns, is positive and face image, when a pitch or left and right side under the condition of big deviation, the recognition rate of face recognition algorithm will also fell sharply.

    Using holographic recognition methods: light face recognition system based on 3 d structure WiMi since the depth of the research learning algorithm and the structure of 3 d optical depth structure light cameras. Fault tolerance rate can reach one over one million.
  • Shade problem: cooperate for the case of human face image acquisition, cover problem is a very serious problem. Glasses, hats and other accessories, the acquisition of face image is probably not complete, which affect the behind of feature extraction and recognition, even lead to the failure of face detection algorithm.

    Using holographic recognition methods: structured light projection after the light of the specific information to the surface, the camera collection. According to the object causing the change of the optical signal to calculate the information such as location and depth of the object, and then recover the whole 3 d space. Even wearing glasses, sunglasses, can quickly recognize faces.
  • Age change: as the change of the age, facial appearance is changing, especially for teenagers, this change is more obvious. For different age groups, the recognition rate of face recognition algorithm is also different.

    Ways: using holographic recognition by machine learning algorithms, each brush face computer system will be according to the features of the first photo you learn details, after every use more data and information collected.
  • A variety of expression: different caused changes in facial expression is different, in addition, different people of the same expression effect is also different, so it is difficult to use unified standard to accurately divide the various expressions of the influence of different people.

    Using holographic recognition methods: through the deep learning algorithms, each brush the face pose is impossible to exactly the same, such as deep learning system will be according to the features of each of your picture learn details, the expression of gathering more data information.
  • Background complex: when monitoring the background of the scene is more complicated, face detection rate will be reduced, thus can adapt to the complex background environment face detection algorithm is face recognition technology is very difficult to solve the problem.

    Using holographic recognition methods: structured light projected onto the face, after the rest of the background will not capture, capture the 3 d model of human face information only.
