Long-distance anti-counterfeiting face iris capturing apparatus and method of moving target

Abstract

The invention, which belongs to the protection equipment field, discloses a long-distance anti-counterfeiting face iris capturing apparatus and method of a moving target. The capturing apparatus comprises at least one camera group including a plurality of pairs of cameras, a shooting camera for shooting an anti-counterfeiting face iris of a moving target, and a zoom lens control device connected with a control module. Each pair of cameras is capable of forming binocular parallax independently and has same shooting areas; one large camera group includes a plurality of camera pairs; each pair of cameras has different focal lengths; all camera groups are connected with the control module as central data processing and control equipment. The zoom lens control device cooperating with the shooting camera is used for adjusting the focal length of the shooting camera. Compared with the prior art, the long-distance anti-counterfeiting face iris capturing apparatus has the following advantage: the plurality of cameras that are formed by a plurality of camera pairs and correspond to long-distance, intermediate-distance, and short-distance targets are capable of detecting moving targets at different distances in the monitoring area, so that a problem that the cameras extract too small target signals because of long distances of the targets and thus the targets can not be extracted or are extracted unstably, so that the system is not reliable is solved.

Description

technical field

[0001] The invention belongs to the field of security equipment, and in particular relates to an anti-counterfeit human face iris capture device and method for a long-distance moving target. Background technique

[0002] Safety issues have always been one of the core issues of public concern. Using the monitoring system to identify suspects or criminals is an important function. For example, using the captured target image for manual interpretation or comparison with the face and iris in the database or automatically identifying suspicious, criminal or fugitive personnel, play a role in security warning, role in assisting investigations. If the captured image of the target is not clear enough, it will be difficult for the monitoring system to function.

[0003] The cameras and camera lenses currently used in monitoring systems are basically fixed-focus lenses. For example, to capture a car running a red light at a traffic intersection, a fixed-focus lens i...
