SIGGRAPH/LOS ANGELES – (August 4, 2015) – Christie®, the leader in visual and audio technologies, is proud to once again be a Platinum-level sponsor at the 42nd International Conference and Exhibition on Computer Graphics and Interactive Techniques (SIGGRAPH) taking place August 9-13 at the Los Angeles Convention Center. Christie is participating in an Emerging Technologies demonstration displaying its latest digital “sandbox.” Attendees will also see Christie projection technology in action across the conference, including lighting up BARTKRESA Design’sShogyo Muyo 360-degree projection mapping installation.
Projection mapping in 30 seconds or less
Attendees to SIGGRAPH 2015 will see the latest in projection mapping technology from Christie in an Emerging Technology demonstration displaying its latest digital “sandbox,” taking place in South Hall G. Using auto-calibration, Christie is taking a process that was once complicated to execute and time consuming to calibrate and scaled it down to less than 30 seconds. Attendees will see a 3D printed apartment building projection-mapped in real-time, a process for which Christie claimed two patents on June 2, 2015.
The patents are the collaborative work of several Christie team members including John Vieth in the Advanced Technology team, Roy C. Anthony on Christie’s Research and Innovation team and former Chief Technology Officer, Paul Salvini. Christie patented a dynamic, mapping-calibration process that uses cameras, projectors and 3D geometry to augment any real object's surface with imagery defined by a virtual model.
The first patent claims the invention of using cameras to “see” what is in front of the projector, sending that information to a computer, which then uses that information to determine in 3D what is being projected on. The process then identifies the objects in the scene, looks up the virtual imagery corresponding to those objects, adjusts the image to be projected accordingly and sends that adjusted image to the projector for display. When 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. Only the frame rate capability of the projector limits how quickly the image can be adjusted and projected.
The second patent claims a specific application of the general invention. The application covers scenarios where the parameters of the projected image would alter themselves in response to variations in the scene the camera sees.
“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 at SIGGRAPH 2015.
