Embodiment Construction

[0022] The present disclosure generally relates to optimizing projection paths for scanning laser projectors. With scanning laser projectors, the occurrence of flicker is affected by a variety of factors such as the total scan path length of the projector, the order of path traversal, the number of vertices to be displayed, and temporal path consistency. The disclosed systems and methods minimize these factors while also maximizing the number of displayable points.

[0023] In one embodiment, the method includes capturing information of the scanning behavior of the laser projector under various path tracings. Using this information, a model is generated that describes the behavior of the laser with respect to the relevant properties. This model is used to compute an approximate optimal scan path for one or more images, which is a spatially accurate projection of the input points in a minimum amount of time, and which also takes into account the spatiotemporal path distributio...

Abstract

The present invention relates to a projector optimization method and system. The present disclosure relates to methods and systems for optimizing projectors for projecting content. In one embodiment, the method comprises receiving, by the processing element, a plurality of test images corresponding to test patterns projected by the projector on the projection surface, wherein each of the test patterns comprises at least two points, by The processing element compares the plurality of test images to evaluate one or more projector characteristics related to the distance between two points, generates by the processing element a projector model representing the one or more projector characteristics, and utilizes the The above model is used to determine the projection path that the projector uses for the content.

Description

technical field [0001] The techniques described herein generally relate to methods and systems for optimizing one or more projectors. Background technique [0002] Image projectors are used to project images onto a projection surface such as a screen. In some applications, video projectors are used to enhance, supplement, or otherwise augment objects on surfaces to create dynamic and enjoyable user experiences, such as amusement park attractions. For example, characters or objects may be projected on a surface that virtually "interacts" with real objects on the surface. [0003] Traditional video projectors have many limitations. In particular, conventional video projectors have limited color gamut and brightness. Due to these limitations, presentations using only traditional video projectors can appear dim and unremarkable. Also, in the presence of ambient lighting, the resulting image may appear washed out and unrealistic. In contrast, laser projectors, such as laser ...
