Embodiment Construction

[0031] Such as Figure 10 Shown is a schematic block diagram of a projection system in a preferred embodiment of the present invention, the projection system includes a projection lens unit, an image processing unit, a space recognition unit, and a picture storage unit; wherein, the picture storage unit is used to store preset Project the application screen.

[0032] When working, the space identification unit is used to collect three-dimensional space information on the projection space defined by the projection imaging unit and its projection display area, so as to identify whether there are at least two intersecting surfaces and / or at least one three-dimensional object in the projection space, and Reconstructing three-dimensional space information; the image processing unit processes the projection application picture based on the three-dimensional space information output by the space recognition unit, so as to form a picture corrected based on the at least two intersectin...

Abstract

The invention discloses an automatic three-dimensional mapping projection system and a method. the projection system comprises a projection lens unit, an image processing unit, a space recognition unit and a picture storage unit, wherein the space recognition unit carries out three-dimensional space information acquisition on the projection space and three-dimensional space information reconstruction is carried out; and the image processing unit processes a projection application picture on the basis of the three-dimensional space information to form a graph-corrected picture, the picture is then mapped by the projection lens unit, and a projection image matched with at least two intersection surfaces and / or at least one three-dimensional object is formed in the projection display region.

Description

technical field [0001] The present invention relates to a projector, and more specifically relates to a projection system for automatic three-dimensional mapping and a method thereof. Background technique [0002] Ordinary projectors project images onto a flat surface for people to watch or play games. When there are other three-dimensional objects in the projection display area, the integrity of the picture will be destroyed, and normal projection cannot be performed. [0003] Some projector systems, such as light shows, use three-dimensional buildings as the background, and pre-set the corrected image content to give the audience a pleasing feeling. However, such presetting by manual calculation is time-consuming and laborious, and cannot automatically identify the three-dimensional object in the projection display area, and process the projection application screen to form a graphic-corrected screen based on the three-dimensional object. Contents of the invention [00...
