Embodiment Construction

[0042] figure 1 A projection system 100 (hereinafter referred to as system 100 ) is shown according to some non-limiting embodiments. System 100 includes: 3D (“Three-Dimensional”) rendering device 101 (hereinafter referred to as device 101 ); content player 103 ; alignment system 105 ; and projector 107 . Typically, device 101 is in communication with content player 103 and alignment system 105 , and content player 103 is in communication with projector 107 . Such as figure 1 As shown, device 101 and content player 103 may be combined into one device 108, but in other embodiments, device 101 and content player 103 may also be separate devices. The alignment system 105 is configured to generate pose data 109p, and transmit the pose data 109p to the device 101, which will be described in detail later; wherein the pose data 109p includes feature data corresponding to the virtual camera of the projector 107, so The feature data of the virtual camera is the virtual position,

Abstract

The present invention provides a system and method for geometric distortion correction in projection mapping. Applying a low-resolution mesh to at least one region of the mesh model that is misaligned with a corresponding region of the real-world object. One or more points in the low-resolution mesh are moved; correspondingly, one or more corresponding points in the mesh model are moved, thereby facilitating alignment of the region in the mesh model with a corresponding region of the real world object. Save the updated mesh model. One or more projectors are controlled to project projection images corresponding to the updated mesh model onto real world objects.

Description

technical field [0001] The present invention mainly relates to the field of projectors, in particular to a system and method for correcting geometric deformation in projection mapping. Background technique [0002] Projection mapping is a projection technique that uses specialized software and other techniques to deform and blend images to be projected onto irregularly shaped "screens," such as building surfaces, interior spaces, and natural landscapes. Virtually any surface can be modified to become a dynamic video display of an image that can transform and / or heighten and / or enhance "reality" for the viewer. The most important factor in generating the augmented reality experience described above is an accurate model of the real world object, as any inaccuracy between that model and the object the image is projected on could lead to errors in the projected image, which would at least detract from the viewer experience. One solution to correct the above inaccuracies is to ...
