no. 1 example

[0050] refer to figure 2 , figure 2 It is the first embodiment of the method for shielding the occlusion area by the projection device of the present invention, and the method for shielding the occlusion area by the projection device includes the following steps:

[0051] Step S110, acquiring display content of the projection area.

[0052] In this embodiment, the projection device mainly refers to a projector. A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. 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. The occluded area refers to an area blocked by an occluder, and the occluder may be a person or an object, which is not limited here. Computer (computer), c...

[0059] refer to image 3 , image 3 The second embodiment of the method for shielding the occlusion area for the projection device of the present invention includes:

[0060] Compared with the first embodiment, the second embodiment includes step S210, step S220, step S230, and step S240, and other steps are the same as the first embodiment, and will not be repeated here.

[0061] Step S210, performing shape correction on the projection area.

[0062] In this embodiment, because there may be certain shape changes in the projection area, such as excursion, contraction, etc., the computer needs to correct the shape of the projection area to ensure the projection effect.

[0063] Step S220, after the shape correction is completed, the projection content of the projection area is captured by the camera; there is no abnormality in the projection area.

[0064] In this embodiment, after the shape correction is completed, the computer captures the projection content of the project...

Abstract

The invention discloses a method for shielding an occlusion area of projection equipment. The method comprises the following steps: acquiring display content of a projection area; comparing the display content with the emitted projection content to obtain an abnormal change area of the projection area; and superposing the occlusion area on the projection content according to the abnormal change area. The invention further discloses a device and a computer readable storage medium, and the problem that in the prior art, projection content is shielded by a shielding object, and user experience isaffected is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular to a method, a device and a computer storage medium for shielding an occlusion area of ​​a projection device. Background technique [0002] At present, projection equipment, such as a projector, is a common display device in contemporary daily life, and can be used for teaching display, business promotion, etc. In daily meetings, etc., it is even more impossible to participate without a projector. [0003] However, in the daily application of the projector, we often encounter embarrassing situations such as the presence of occluders blocking the projected content, so that the projected content is also projected on the occluder. For example, when we stand in front of a projector to explain documents to customers or students, the projector will also project images onto people, resulting in colorful people, which will affect the effect of demonstration or explanation, an...
