"IntelliSense staring Hyperspectral Imager"'of expert's review meeting will be held in Shenzhen

Release date:2017-05-11


With the continuous development of science and technology in China and the continuous improvement of social civilization, the demand for the identification of physical evidence in the field of public security will also increase day by day. At the same time, The difficulty of identification of physical evidence is also increasing. The spectral characteristics of different physical evidence are used to realize the examination of morphology and composition, and the qualitative and quantitative analysis of the evidence of trace is carried out, which makes the examination more scientific and the testing method more rigorous. The result of examination is more directional and is a difficult problem to be solved urgently in the field of criminal imaging technology in the field of physical evidence identification.

By April 28, 2017, Chinese Public Security magazine, Shenzhen Security Industry Association organized the "intelligent perception staring hyperspectral imager" review will be held in Shenzhen. This review will be submitted to Shenzhen Wayho Techonology. Expert group headed by the Ministry of public security police equipment experts chief expert, former public security department deputy director of Finance Bureau Tao Junsheng senior engineer; vice chairman of the National Police Photographers Association members, director of Zhou Yunbiao, former Ministry of public security evidence identification center, the Ministry of public security evidence identification center deputy inspector Xu Xiaojing researcher, vice president Professor Dan Daguo Chinese Interpol college, Dean of Chinese People's Public Security University Institute of criminal science and Technology Professor Jiang Zhanqing, National Police Commission Expert China, public safety magazine editor Yang Jincai, and from Jiangxi, Guangdong, Shanghai, Tianjin, Guangzhou, Shenzhen Dalian, Lanzhou, Dongguan and other provinces and municipalities, including criminal technology, forensic identification, police protection and other industry departments and Ministry of public security quality inspection center, the research institutes of the Ministry of physical identification, image technology, document inspection, inspection and a total of 28 experts in the industry.

On the morning of the same day, all the experts travelled by car to Dari and the company's location in Nanshan Science and Technology Park, visited the R & D center and the production workshop of wayho techonology. The company's technicians demonstrated the products on the spot. Experts were interested to watch the "hyperspectral imager" show various functional applications, one after another to express approval and approval, and on the technical issues of concern with the company's technical personnel were discussed.

Subsequently, Cui Dongwei, product director of the company, demonstrated and explained the research and development background, process and results of the "hyperspectral imager" project. According to the introduction, the key technology of the "hyperspectral imager" project will move towards a higher appraisal capability. The main competitive advantages are the design of LCTF liquid crystal tunable filter device and the encapsulation of compact cascade structure, the large aperture liquid crystal filter and high resolution. High frame frequency array image sensor photoelectric integration and synchronization control technology, spectral resolution enhancement and angle of view compensation technology; staring hyperspectral imager data acquisition, Collaborative control and high speed transmission technology and equipment lightweight compact process structure design; space, spectrum, time 3D information fusion and feature extraction technology, and joint diagnostic spectral features, Intelligent analysis method of spectral data of spatial structure feature and time correlation; establishment of one-key performance monitoring and fault intelligent diagnosis method of spectral video imager; design of the whole machine test scheme of the system for indoor and outdoor tests, The performance evaluation system and authenticity test of spectral imager are established, the feedback mechanism of each test link is established, the performance parameters of the instrument are optimized, and a set of spectral data collection is established. The standardized technical scheme and application demonstration flow of preprocessing and special application in the field of forensic evidence.

After listening to the project report of wayho techonology, the experts advised the main R & D technicians of the company, and discussed the technical, reliability and practicability of the project. The hyperspectral imager has made a breakthrough in the research and development of key technologies such as liquid crystal tunable filter (LCTF) design and technology. It has its own intellectual property rights and has obtained many patents and software copyright. Hyperspectral imagers can quickly and simply capture spectral images, and can obtain spatial information and spectral information of each pixel in the range of full visual field, which provides a new nondestructive testing method for forensic scientific evidence testing and analysis.

Therefore, the experts of the review team agreed that LCTF, the core technology of the hyperspectral imager, had filled the gap in China, and its comprehensive technical level was leading in China and was the first in China, reaching the advanced level of similar international products. It is a new high-tech product for forensic scientific evidence inspection and analysis. It is agreed that the project has passed this review. Meanwhile, it is suggested to further increase the application in the field of public security according to the market requirements.


In addition, in order to better improve the functions of the intelligent perceptive staring hyperspectral imager and accelerate the shaping of the equipment, The Criminal Technology Department of the Criminal Police detachment of Shenzhen Public Security Bureau and wayho techonology Science and Technology Co., Ltd. jointly set up a "hyperspectral technology application joint laboratory."
