Abstract

The invention discloses a filter-frequency-adjustable high-precision face recognition system based on linear driving. The system is mainly composed of a facial image collector, a microprocessor MCU, a signal processing circuit, an adjustable filter circuit, a constant current source circuit and a pattern recognition circuit, wherein the microprocessor MCU is connected with the facial image collector, the signal processing circuit, the adjustable filter circuit, the constant current source circuit and the pattern recognition circuit are connected with the microprocessor MCU, the constant current source circuit is connected with the adjustable filter circuit, and the pattern recognition circuit is connected with the constant current source circuit. The system is characterized in that a linear driving circuit is further arranged between the signal processing circuit and the adjustable filter circuit; the linear driving circuit is composed of a driving chip U, a triode Q3, a triode Q4, a triode Q5, a triode Q6 and the like. The linear driving circuit enables the recognition system to maintain good stability even in the process of recognizing faces at different distances.

Description

technical field [0001] The invention relates to a face recognition system, in particular to an adjustable filter frequency high-precision face recognition system based on loss suppression. Background technique [0002] With the vigorous development of high technology, the face recognition system has been widely used as a human body password because of its convenience. In addition, intelligent management has entered people's social life now, and intelligent buildings have sprung up one after another to meet the needs of the information age. As a noble building and office environment, it must meet the current and future development needs functionally. Become a base for cultural and economic development. Therefore, the face recognition system has been applied to Daxia's access control recognition system. However, due to the flaws in the design of the current face recognition system, it is inevitable that the recognition of the face recognition system will be rejected when the ...
