Description
Technical field
Invention is related to control projection regulation technology field, particularly belong to a kind of one projector three-dimensional surface projection and present be
System.
Background technology
When projection target thing is on-plane surface, need to consider the rectification with the surface of 3D solid for the projected picture of plane.
For example when need on cubical three faces project when, traditional scheme be using three projectors respectively toward on a face
Projection, in traditional three-dimensional surface projection, core concept is to set up an accurate 3 d surface model, then by this
The co-ordinate zero point in 3D engine put into by model, and the virtual camera position in engine be set to physical projector with respect to
The three dimensional space coordinate on solid threedimensional surface.But this process is extremely difficult, need the position continuously attempting to adjust projector
And angle, to reach satisfied effect.Particularly after projector rocks, adjustment again is wasted time and energy.
Content of the invention
The purpose of invention there is provided a kind of one projector three-dimensional surface projection presentation system, can rapidly calibrate three
Dimension surface projection, as long as whole process takes several seconds, and three-dimensional projection plane's laminating degree is fine.
