The keeper's note
Optimizes a projector by analyzing test images of projected patterns on a surface to correct for the surfaces properties.
Abstract
The present disclosure relates to a method and system for optimizing a projector for projection of content. In one embodiment the method includes receiving by a processing element a plurality of test images corresponding to test patterns projected by the projector on a projection surface, where each of the test patterns include at least two points, comparing by the processing element the plurality of test images to assess one or more projector characteristicsrelated to a distance between the two points, generating by the processing element a projector model representing the one or more projector characteristics, and utilizing the model to determine a projection path of the projector for the content.
