The keeper's note

A wavelength-multiplexed show display system that illuminates ride/show set surfaces for viewers wearing 3D glasses tuned to specific wavelength sets per eye.

Abstract

A display system for illuminating surfaces of objects in a ride or show set for viewing by a viewer ina viewing space wearing three-dimensional (3D) glasses or headgear. The 3D glasses or headgear is adapted to pass or transmit light associated with a first set of three wavelengths to a left eye and to pass or transmit light with a second set of three wavelengths differing from the first set of three wavelengths. Each of these wavelengths may be associated with a primary color wavelength for providing left and right eye content to a viewer. The system, therefore, may include a wavelength multiplex visualization (WMV) projection system projecting light having the first and second sets of three wavelengths to provide the viewer stereo content via the 3D glasses or headgear.

Background

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a diagram or functional block diagram of an amusement park ride with a 3D display system of the present description showing use of a WMV light source or fixture to provide normalized or balanced show lighting for a physical set for viewing by a viewer wearing WMV-based 3D glasses;

FIG. 2 illustrates flow diagram of a control algorithm or process that may be carried out by a controller of a 3D display system to operate a WMV light source to achieve a desired display or special effect;

FIG. 3 illustrates a perspective view of an operating WMV light source with two arrays of three LED emitters or bulbs (i.e., two sets of RGB LED emitters or bulbs);

FIGS. 4A-4C illustrate the WMV light source of FIG. 3 in three additional operating states (e.g., in response to control signals from a controller such as the one shown in FIG. 1); and

FIG. 5 illustrates a functional block or schematic drawing of another 3D display system of the presentdescription.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The inventors recognized that more and more amusement park attractions such as dark rides are being developed and implemented that use stereo projection to deliver show scenic and story content. The stereo or 3D projection is typically one of the two types of wavelength multiplexing visualization (WMV) technology discussed above in the background, and these two types of WMV technology are based on a comb filter t

Claims

1. A display system for illuminating surfaces of objects for a viewer in a viewing space wearing 3D glasses or headgear passing light associated with a first set of three wavelengths to a left eye and passing light with a second set of three wavelengths differing from the first set of three wavelengths, comprising: a wavelength multiplex visualization (WMV) projection system projecting light having the first and second sets of three wavelengths to provide the viewer stereocontent via the 3D glasses or headgear; and a WMV light source providing colored light for illuminating the surfaces of the objects for the viewer to observe through the 3D glasses or headgear, wherein the colored light comprises light at a wavelength matching one or more wavelength in the first and second sets of three wavelengths. 10. A display system foran amusement park ride following a ride path, comprising: along a first length of the ride path, a 3D projection system projecting stereo content including left eye imagery with red light at a first wavelength, green light at a second wavelength, and blue light at a third wavelength and further including right eye imagery with red light at a fourth wavelength differing from the first wavelength, green light at a fifth wavelength differing from the second wavelength, and blue light at a sixth wavelength differing from the third wavelength; along a second length of the ride path, a physical set; and a light source adapted for illuminating the physical set with lighting comprising red light at the first wavelength, green light at the second wavelength, blue light at the third wavelength, red light at the fourth wavelength, green light at the fifth wavelength, and blue light at the sixth wavelength. 15. A method of illuminating a physical set, comprising: first providing show lighting comprising first light with light matching at least one wavelength defined in a setof left eye wavelengths for a WMV projection system; and second providing show lighting comprising second light with light matching at least one wavelength defined in a set of right eye wavelengths for the WMV projection system.
