The keeper's note

CV-driven interactive entertainment/ride system.

Abstract

The present disclosure describes a method for providing an interactive experience. The method includes illuminating, by an enhancer, an area with light having wavelength invisible to humans. A plurality of image detectors capture at least two images of a person in the area including a portion of the light reflected from the person. A processing element determines a first skeletal feature of the person based on the at least two images. The processing element determines a position characteristic of the first skeletal feature; constructs, from the first skeletal feature, a vector in three dimensions corresponding to the position characteristic; and outputs an interactive effect based on the position characteristic.

Background

BACKGROUND

Motion capture systems that detect and translate the pose of a person, including the position and motion of the person's figure to a computer for use in rendering virtual characters or other visual effects, are widely used in gaming, entertainment, filmmaking, and other applications. Traditional motion capture systems that detect a person's pose may use markers placed on the person, for instance at joints of limbs, on the skin above facial muscles, clothing, or other locations on, or associated with, a person. The markers are then detected in images by cameras and used to re-create the pose in a virtual space, for example generating an animation of the pose via a computer. The virtual pose of the person may enable the person to interact with a virtual environment, or may be used as the basis for the pose of a virtual character.

However, as these types of traditional systems require a person to wear markers on his or her body and that such markers are accurately positioned, such systems require intensive calibration and setup processes, which limits their application and use. As such, these types of systems may not allow seamless, immersive theatrical, gameplay, theme park ride, or other entertainment experiences. BRIEF SUMMARY

A method for providing an interactive experience is disclosed. The method includes illuminating, by an enhancer, an area with light having a wavelength invisible to humans. A plurality image detectors receive at least two

Claims

1. A method for providing an interactive experience comprising: illuminating, by an enhancer, an area with light having a wavelength invisible to humans; receiving, by a plurality of image detectors, at least two images of a person in the area including a portion of the light emitted by the enhancer and reflected from the person; determining, by a processing element, a first skeletal feature of the person based on the at least two images; determining, by the processing element, a position characteristic of the first skeletal feature; constructing from the first skeletal feature, by the processing element, a vector in three dimensions corresponding to the position characteristic; and outputting an interactive effect based on the position characteristic. || 23. A method of calibrating a camera comprising: positioning a calibration target within a field of view of a camera; capturing, by the camera, an image of the calibration target; determining a difference between the image of the target and a physical characteristic of the calibration target; determining a characteristic of the camera based on the difference; and moving the target automatically by an actuator on a predefined path within the field of view of the camera. || 25. A method of calibrating a camera system comprising: positioning a calibration target in a physical environment within a field of view of a plurality of cameras; capturing, by each of the plurality of cameras, an image of the calibration target; determining a reference point in the image; determining a respective position of the reference point with respect to each of the plurality of cameras; adjusting position information of the camera based on the respective position of the reference point; constructing a virtual representation of the field of view in three dimensions based on the reference point in the physical environment. || 27. A system for augmenting a user experience comprising: a wearable article adapted to be worn by a person, a wearable article including: a processing element that encodes data related to a virtual characteristic of the wearable article, a transmitter that transmits the encoded data to an entertainment environment; a detector in the entertainment environment that detects the transmitted data; a processing element that receives the data detected by the transmitter and changes a characteristic of the entertainment environment according to the virtual characteristic of a wearable article.
