Problems solved by technology

However, as mentioned earlier, the projected objects in the projection mapping are usually irregularly shaped objects, so when manually re-generating the mask layer in the projection mapping content, the creator cannot automatically form a shape that is not the same as the mask layer through software, etc. The edge contour of the regular object exactly matches the object contour, and the object contour needs to be manually drawn in the mask layer, which is a very time-consuming and complicated process

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] First, a brief introduction is made to the technical terms involved in the present disclosure.

[0022] As mentioned earlier, projection mapping is a projection technology used to turn real objects into display media for video projection. Among them, videos / images produced by tools such as computers are called projection mapping content, objects as the display medium for projection are called objects to be projected, and the overall result obtained after projecting projection projection content onto objects is called Projection projection works. The projection projection content is usually composed of a content layer and a mask layer. The content layer is the background, which is usually specific content such as video, image, animation, etc...

Abstract

The invention provides a method, equipment and system for generating a lightscribe projection content. The method comprises: after a position change of lightscribe projection equipment is obtained, the lightscribe projection equipment is used for shooting an image of a projected material object; all profile points, corresponding to the profile of the projected material object, in a mask layer of an original lightscribe projection content before the position change are determined; on the basis of stereoscopic vision matching, corresponding points of all profile points in the obtained image of the projected material object are determined, and a new mask layer is formed based on the set of the corresponding points; and with the new mask layer, a new lightscribe projection content after the position change of the lightscribe projection equipment is generated. On the basis of the lightscribe projection content generation technology, the new mask layer can be formed automatically by using the stereoscopic vision technology when the position of the projection equipment changes, so that the new lightscribe projection content can be generated rapidly and conveniently. Therefore, problems of lightscribe projection content offset and light leak can be solved.

Description

technical field [0001] The present invention generally relates to augmented reality, and in particular to a method, device and system for generating projection mapping content. Background technique [0002] Light sculpture projection, also known as video projection or spatial augmented reality, is a projection technology used to turn real objects, especially irregularly shaped objects, into display media for video / image projection. At present, there are mainly two types of projection mapping, namely, static projection projection and dynamic projection projection. For a static projection mapping work, the relative position between the object being projected and the projector is fixed; while for a dynamic projection mapping work, the object being projected is moving relative to the projector. Fig. 1(a) illustrates some examples of static projection mapping works; Fig. 1(b) illustrates some examples of dynamic mapping projection works. [0003] In order to create a static pro...
