Projection Mapping is Now Possible in Just 30 Seconds with Christie
FEEMONT, CA: Christie, a provider of visual and audio technologies, introduces its latest digital ‘sandbox’, a projection mapping technology. The platform showcases a 3D printed apartment building projection-mapped in real-time, a process for which Christie claimed two patents this year.
With a capability to augment real object's surface with imagery defined by a virtual model, the technology is a dynamic, mapping-calibration process that uses cameras, projectors and 3D geometry. The first patent seeks sanction for the invention of cameras to capture the object in the front of the projector and send the information to a computer thus using that information to determine in 3D what is being projected on. When the visual imagery is projected for display, the process repeats at a sufficiently high rate, and with minimal latency, the viewer will recognize the imagery as attached to the object even if the object is in motion. The technology claims to deliver projection mapping in 30 seconds or less while the speed in adjusting and projecting the image depends on the frame rate capability of the projector.
“Your imagination is the only limitation with Christie technology, and our projection mapping demonstration proves that our technology allows users to put pixels anywhere,” says Roy C. Anthony, Senior Product Manager at Christie and production sessions program chair. The technology was initially showcased in the 42nd International Conference and Exhibition on Computer Graphics and Interactive Techniques (SIGGRAPH).
