摘要： Disclosed is a method for improving the calibration of multiple projector systems in Spatial Augmented Reality systems where multiple projectors are used to project images directly onto objects of interest. The methods and system described herein improve the calibration of multiple projector systems in order to improve the alignment and clarity of projected images by reducing ghosting that can occur with poorly aligned projectors. The system uses a planar photodiode and the projector is used to project a plurality of projection regions, such as scan lines, across the planar photodetector and calculating the position based on weighting measurements by the measured light intensity and projected images in SAR.

摘要： A Spatial Augmented Reality (SAR) system is described. The SAR system includes a SAR device, such as a computer, and a SAR platform such as a set of projectors and object tracking systems that are used for producing a SAR environment. The SAR device can include a loader for receiving and executing one or more SAR application modules and a SAR engine for receiving the input data and for interfacing between the SAR application modules and the output. The architecture of the SAR engine provides a SAR environment independent interface between the SAR application modules and the projectors and object trackers. The SAR engine is responsible for providing perspectively correct projected images in the SAR environment and performing coordinate transformations, and providing updates to application modules, as well as automating many common tasks.
