Recently, the 2017 South Asian Southeast Asian Countries Commodity Fair and Investment and Trade Fair was held in Kunming. More than 4,000 companies from 86 countries and regions participated in the Kunming Dianchi International Convention and Exhibition Center, involving 19 series of events and 8,000 standards in 17 pavilions. More than 500,000 booths were on display.
The security task was tight and the task was heavy. Hikvision fully cooperated with the provincial and municipal bureaus to deploy the task. With the help of the integrators, 9 personnel security checkpoints were completed within three days, and 42 Haikang squatters were completed. Face capture machine; 6 vehicle entrances and exits, 12 sets of squat vehicle capture machine installation and commissioning work. And it is connected with the face & car face recognition system of the provincial and municipal bureaus to realize the control of people and vehicles entering and exiting the core area of ​​the exhibition.
Haikang's deep face capture machine installation situation
The system pushes the face data to the higher-level public security organs by means of the library cascading method, which effectively ensures the face application of the provincial and municipal public security organs. At the same time, through the introduction of the blacklist library, real-time comparison and early warning with the national escape library, Kunming hand bank and other information.
Hikvision face recognition system application
The deployed face system and the Municipal Public Security Bureau's networking platform, unified bus, seamless interconnection, blacklist for real-time warning, in addition to displaying live face photos, it also provides on-site capture of large pictures and 10 seconds of video before and after. Many key clues provide strong support for the rapid arrest of criminal investigation police.
During the trade fair, Haikang's deep face capture machine collected a total of 973,661 face images. The face image recognition system has a total of 405 key personnel for early warning, including: 5 people who have escaped from the country, 1 person who has seized drugs, 5 people who discovered and disposed of plagiarism, and 1 person who has found evidence of fraud. 328 other key control personnel were inspected. The plagiarism in the museum was down 70.8% compared with the same period of last year. Through scientific and technological means, the smooth convening of the China Business Fair was effectively guaranteed.
In a short period of time, rapid deployment and rapid combat are achieved, and the accuracy rate of early warning is 98%. The front and back of the system incorporates the Hikvision face recognition system with deep learning algorithm. The actual combat effect can be “fast†and “quasiâ€. To describe:
1 deployment fast
Haikang's deep face capture machine can select different shapes, focal lengths and resolutions for different scenes. The camera supports power zoom, which enables you to capture faces at different distances by adjusting the focus remotely. For face capture of larger scenes, you can use a 6 megapixel squat face grabber.
2 capture fast
Haikang's deep face capture machine with high-performance GPU chip can detect and track 30 faces at the same time. For each face, based on the scoring mechanism, the optimal face image is output. For fast-moving faces (up to 30 yards for electric cars), fast capture is also possible.
3 faster than
Haikang Facebook adopts high-density GPU hardware architecture design and integrates face learning algorithm based on deep learning. Single device can realize analysis and comparison of hundreds of faces per second, and its performance is excellent. In the blacklist comparison, the system is completed within 3 seconds from the capture of the suspect to the system comparison warning, and the rapid warning comparison provides an effective time guarantee for the arrest of the criminal investigation police.
4 capture
In addition to face snapshots, the accuracy must be guaranteed. In the daytime entrance and exit scene, the squat face capture machine has a detection accuracy of over 98.4%, and the face detection rate is as high as 98.7%. The high accuracy and detection rate of the front-end face capture ensure the accuracy of the entire face recognition system.
5 ratio alignment
Haikang's Facebook has been trained by 10 million high-quality samples, and the accuracy of face recognition has been significantly improved compared with the previous generation algorithm. In the case of a large posture such as a 45° deflection of the human face and a vertical deflection of 25°, it is still possible to accurately identify and compare.
The outstanding performance of the face recognition system at the trade fair was highly praised by the leaders of the Yunnan Provincial Public Security Department and the Kunming Municipal Public Security Bureau.
