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 technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a co-existence of an intervening component. When a component is considered to be "set on" another component, it ...

Abstract

The present 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 includes step S1: calculating the pictures taken by the constructed neural network to obtain moiré-removed pictures, and the moiré-removed pictures The picture is decoded by Gray code; step S2: generate a mark table after processing the decoded picture, and determine the mapping relationship between the projector pixel and the picture pixel according to the mark table corresponding to different Gray code digits; step S3: according to the The mapping relationship generates a two-dimensional mapping picture of the perspective of the projector; step S4: edit the two-dimensional mapping picture as a draft, and output the edited content to the projected object through the projector to realize 3D projection. The 3D projection implementation method provided by the present invention calculates the two-dimensional mapping picture of the perspective of the projector, and directly performs corresponding artistic operations on the corresponding two-dimensional mapping picture, without any distortion adjustment on the picture, and the operation is simple .

Description

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