Embodiment 1

[0018] A device for automatically calibrating the face of a human body with a monitoring camera, comprising at least one group of movable camera mechanisms, the camera mechanism is provided with an infrared detection component, and the infrared detection component is used to obtain a human body height signal and transmit it to a single-chip microcomputer, The single-chip microcomputer sends a control signal to the camera mechanism to lift it to a suitable height and align it with the face of the human body.

[0019] In this embodiment, the camera mechanism moves up and down, and both up and down are provided with limited positions.

[0020] The camera in the camera mechanism in this embodiment moves on the track through a stepping motor.

[0021] The equipment of this embodiment can be installed on the wall, and also can be installed on fixed equipment such as ATM machine panel.

Embodiment 2

[0023] as attached figure 1 As shown, a method for automatically calibrating a human face by a surveillance camera includes the following steps:

[0024] A. The single-chip microcomputer is initialized, and the infrared detection part is used to obtain the real-time signal of the human body height and send it to the single-chip microcomputer;

[0025] B. The single-chip microcomputer calculates the height position of the camera according to the height information of the human body, and sends a signal to the stepping motor;

[0026] C. The stepper motor controls the camera on the track to move up and down to the calculated height position, so that the camera is aimed at the face of the human body.

[0027] There are upper and lower limits on the track to set the moving range of the camera. Within the specified range, the camera moves up and down driven by a stepping motor.

Abstract

The invention relates to a control device and method for a surveillance camera, in particular to a device and method for automatically alighting the surveillance camera with the human face. According to the device and method, height information of a human body is collected through infrared detection and fed back to a single-chip microcomputer, the single-chip microcomputer controls the camera to ascend or descend to a proper height position to collect videos, and the problem that a fixed surveillance camera can not be aligned with the human face is solved.

Description

technical field [0001] The invention relates to a control device and method for a monitoring camera, in particular to a device and a method for automatically calibrating a human face by a monitoring camera. Background technique [0002] Under the existing technology, in order to make the figure in the camera clearer, most of all self-service equipment rely on adding a camera for online intercom or video monitoring, because the ordinary camera installation is only fixed on the machine to transmit the image. And because people's heights are different, if the camera is fixedly installed, the situation that the monitoring video will not be aimed at the face will appear, that is, it will not be able to play its due role. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a device and method for automatically calibrating the face of a human body with a monitoring camera, which collects human body height information ...
