Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0037] A method for automatically capturing a high-definition human face in a target area, comprising steps in the following order:

[0038] 1. Input the parameters of the target area (the length, width, and height of the target area are denoted as L, W, and H), the height of the camera installation from the ground is hc, and the distance from the left-hand wall of the students when they are sitting is lc.

[0039] 2. Take the installation position of the PTZ camera as the coordinate origin O(0,0,0), pass through the point where the PTZ camera is located, and establish a spatial rectangular coordinate system (xyz), and take the wall where the camera is installed as the plane where the x-axis and y-axis are located , the z-axis passes through point O and is perpendicular ...

Abstract

The invention discloses a high-definition face automatic snapshot method in a target area. The method comprises the following steps in sequence: establishing a space rectangular coordinate system; and establishing a space model through the geometric position, and calculating a shooting angle and a zooming multiple of a shooting target relative to a camera mechanical holder; meshing a shooting scene, and positioning geometric positions of all positions relative to a pan-tilt camera in a target area; and performing grid traversal to realize non-blind area automatic cruise shooting, and inversely calculating the position data of the grid in the space coordinate system through the grid number to guide the control of a pan-tilt control program. The system is used for realizing automatic non-blind area face photo snapshot, can realize automatic non-perceptual image recognition face attendance checking, and reduces the manual workload.

Description

technical field [0001] The invention relates to the field of face recognition and attendance checking, in particular to a method for automatically capturing high-definition faces in a target area. Background technique [0002] It is a high-frequency demand for daily management work, such as maintaining the normal teaching discipline and order of the school, and ensuring that the various work tasks of the school can be carried out smoothly. It is a very important key link, and it is also a very important means to strengthen the discipline management of the region and restrain daily learning and behavior. In the prior art, the above-mentioned management work is done manually, and the work efficiency is low and error-prone. [0003] Therefore it is necessary to propose a new technical solution to solve the above problems, to better complete the above management work. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings and ...
