Problems solved by technology

There are also some embedded architectures, but the overall structure has not changed. They are all in the mode of obtaining images from cameras and then processing them, which cannot be used for remote monitoring and processing.
Moreover, such products have disadvantages such as high cost, poor stability, difficulty in upgrading and maintenance, and incompatibility with existing monitoring networks.

Embodiment 1

[0049]Embodiment 1: it has a network interface module 1, is used for receiving the video stream or figure from network; A dual-core chip SOC module 2, is used for detecting the video stream image and figure that receive from network, judges whether wherein contains people face information, and identify the face; the network interface module 1 is connected with the dual-core chip SOC module 2; the address decoding 3 of a CPLD is used to manage the peripheral equipment of the dual-core chip SOC module 2; a DDR2 high-speed Computational memory 4 is used as the memory of dual-core chip SOC module 2; an external program memory NAND Flash5 is used to store detection and identification programs, and a hard disk 6 with an IDE is used to realize large-capacity access of local data; the above-mentioned dual-core The chip SOC module 2 is connected to the DDR2 high-speed computing memory 4 through the DDR2 data bus; the address decoding 3 of the CPLD is connected to the external program me...

Embodiment 2

[0050] Embodiment 2: What is different from the above-mentioned embodiment is: without a hard disk, realize the processing of local small data, detect people's faces locally and extract feature values, and pass the extracted feature values ​​and the normalized image of people's faces to The monitoring center server implements the comparison algorithm part on the server side. This design is suitable for the comparison and identification of massive image database data.

[0051] 2, in conjunction with accompanying drawing 2,3 and embodiment, the recognition method of a kind of face recognition system of the present invention is further described as follows:

[0052] A recognition method for a face recognition system, the steps are as follows:

[0053] A. Compressed video decoding: perform compressed video decoding on streaming media data transmitted over the network to obtain digital image sequences; input: streaming media data; output: decompressed digital images;

[0054] B. P...

Abstract

The invention relates to a face recognize system, comprising a network interface module, a dual-core chip SOC module connected with the network interface module, a CPLD address code, a DDR2 high-speed operation memory, and an external program memory, or even with a hard disk with an IDE. The dual-core chip module is connected with the high-speed operation memory via a data bus. The CPLD address code via an EMIF bus is connected with the external program memory NAND Flash or connected with the IDE hard disc too. And the whole system is powered by a power module. The recognize method comprises video code compression, pretreatment, motion check, face positioning, organ positioning, normalizing, character extraction, face comparison, and data communication. The invention has the advantages in high recognize rate and high recognize speed, strong data processing ability, better compatibility with prior detect network, stable operation, easy upgrade and maintenance, with low cost.

Description

Technical field: [0001] The invention relates to a face recognition system and recognition method, which is a special embedded technology for automatic face recognition from network streaming media data, belongs to the field of electronic automatic recognition technology, and is especially suitable for network monitoring systems with high intelligence requirements , such as: urban public security monitoring and alarm system, identity confirmation through face recognition, and it can also be used as a video surveillance system in customs, airports and other occasions to record and save video recordings. technical background: [0002] Computer face recognition refers to the use of computer analysis image and pattern recognition technology to identify or verify one or more faces from static or dynamic scenes based on the known face sample library. Usually, the basic information that can be obtained after the recognition process includes the position, scale and posture informati...
