Embodiment Construction

[0017] The specific implementation of the method for masking a human face in a projection area provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The invention provides a method for masking human faces in the projection area, with figure 1 It is a flowchart of a method for masking a human face in a projection area according to a specific embodiment of the present invention. Such as figure 1 As shown, the method for masking a human face in a projection area according to the present invention comprises the following steps:

[0019] Step S11, providing a projector and a binocular camera whose relative positions are fixed. In order to prevent the strong light projected by the projector from damaging the human eyes, but cannot have a significant impact on the picture projected by the projector, the method adopted in the present invention is to weaken the area of ​​the face projected by the projector, especiall...

Abstract

The invention relates to the technical field of electronic information, and particularly relates to a method for masking a human face in a projection region. According to the method provided by the invention for masking a human face in a projection region, a coordinate set of a human head or a human face in front of a projector in a three-dimensional space is positioned and tracked by using a binocular camera, the three-dimensional coordinate set is mapped to an image plane of the projector so as to acquire a two-dimensional coordinate set corresponding to a human face region, an electronic masking region is established in the coordinate set region, and projection light shielding is realized, so that damages imposed on the human eyes by strong light emitted by the projector are effectively avoided. In addition, the equipment cost is low, the application range of the projector is expanded, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method for masking a human face in a projection area. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living standards, projectors are used more and more in people's lives, especially in business speeches and education industries. A projector, also called a projector, is a device that projects images or video onto a screen. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. In recent years, with the rapid development of LED light source and laser technology, micro projectors have shown a blowout growth, and a large number of families are also using projection equipment. However, the principle of projection equipment determines that it must have an extremely b...
