Security check machine used for people, certificate and ticket verification system

Abstract

The invention discloses a security check machine used for a people, certificate and ticket verification system. A chassis is locked on a desk body through bolts and nuts; the middle of the chassis is provided with an internal thread; a supporting tube is hollow; an external diameter is tapped with one section of thread; the supporting tube and the chassis are connected through the thread; the vertical regulation of the height of the security check machine is the degree 1 of freedom of the security check machine; and the horizontal rotation of the supporting tube is the degree 2 of freedom of the security check machine. The security check machine used for the people, certificate and ticket verification system has the advantage of multi-degree-of-freedom regulation, and tested people of different heights can guarantee to be captured and locked within a certain range by a camera through the regulation of each degree of freedom. The security check machine is provided with at least one group of LED (Light Emitting Diode) supplement lights which can be automatically turned on at night or under the environment, including underground passages, with poor illumination condition through the control of a photosensitive sensor, a face is irradiated to obtain a clear imaging effect.

Description

technical field [0001] The invention relates to a security inspection instrument, in particular to a security inspection instrument used in a person card verification system. Background technique [0002] The acquisition of images in face recognition is very important, directly related to the success or failure of witness inspection, accuracy and detection rate, first of all, high-resolution high-definition cameras should be considered in the selection of cameras, wide-angle without distortion is more advantageous, specific The security inspection instrument of the present invention adopts Logitech C920USB output high-definition camera, automatic focusing, and can obtain 30 frames of images per second; secondly, the ideal shooting angle is also crucial, and the adjustable support of the security inspection instrument of the present invention has multiple degrees of freedom adjustable , through the adjustment of each degree of freedom, it can ensure that the measured persons ...
