Problems solved by technology

But it also has some obvious shortcomings: the first projected object needs to prepare a relatively high-precision 3D modeling in advance, which undoubtedly greatly reduces the application scenarios of this technology
In addition, the hardware equipment required in 3D projection is extremely expensive, at least two high-resolution industrial cameras and other auxiliary equipment are required, so the cost is relatively high

Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0054] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

The invention relates to the technical field of projection and image processing, and discloses a remote fast 3D projection method based on structured light scanning, which comprises the following steps: S1, calculating a shot picture through a constructed neural network to obtain a moire-removed picture, and carrying out Gray code decoding on the moire-removed picture; s2, generating a mark table after the decoded picture is processed, and determining a mapping relation between the pixel points of the projector and the pixel points of the picture according to the mark table corresponding to different Gray code digits; s3, generating a two-dimensional mapping picture of the visual angle shadow of the projector according to the mapping relation; and S4, editing by taking the two-dimensional mapping picture as a manuscript, and outputting the edited content to a projected object through a projector to realize 3D projection. According to the 3D projection implementation method provided by the invention, the two-dimensional mapping picture of the visual angle of the projector is calculated, and the corresponding artistic operation is directly carried out on the corresponding two-dimensional mapping picture without carrying out any distortion adjustment on the picture, so that the operation is simple.

Description

technical field [0001] The invention relates to the technical field of projection and image processing, in particular to a remote fast 3D projection method and system based on structured light scanning. Background technique [0002] At present, there are two main applications of projection (mapping) on ​​the market: one is fine projection for 2D flat content, and the other is 3D projection technology for 3D stereoscopic content. [0003] At present, there are mainly two ways to realize the 3D projection of 3D stereoscopic content. One is similar to the fine projection of 2D flat content, which relies on artificially adjusting the distortion of the output image. The other is to use multiple high-precision cameras to reconstruct the three-dimensional scene of the projected object, to accurately determine the spatial relationship between the projector and the projected object, and to realize real-time tracking and automatic automatic correction of distortion. In terms of reali...
