Abstract: A video compression/decompression method designed to carefully balance the amount of work done by the CPU and GPU processes only key image frames to allow fast seeking and backward playback. By using only uniform sized discrete cosine transformation blocks partial frame decoding can be achieved, without using intraframe prediction, enabling playback at increased speeds and skipping decoding of frames that are not displayed. The disclosed video codec may optionally support alpha channel data.

Abstract: A system for mapping a stage includes a lighting fixture, a scanner, and a controller. The lighting fixture includes a visible light source and an infrared light source. The lighting fixture at least partially illuminates the stage with structured infrared light. The scanner detects the structured infrared light on the stage. The controller is connected to the lighting fixture and the scanner. The controller turns on the visible light source in a visible light mode and turns on the infrared light source in an infrared light mode. The infrared light source illuminates at least a portion of the stage with the structured infrared light. The controller also directs the scanner to scan the structured infrared light on the portion of the stage, receives signals from the scanner as scan data, and translates the scan data into three-dimensional location data.

Abstract: A protocol for controlling lighting devices within a network enables bidirectional communication between different connected devices, any of which may function as a server, a device, a broker, or multiple of these roles. Upon initialization of the network, a server device requests a basic configuration data file from each device on the network and, thereafter, requests a more extensive configuration data file identifying capabilities and functionalities of the device which the manufacturer has made discoverable. Each device sends its basic configuration file to the server device upon any of power on, reboot, reset, hardware configuration change, or software change to the respective device. A device on the network can also be a collection of sub-devices each of which may be separately identified, and their respective capabilities evaluated, so that the server can separately control either the device or any of the individual sub-devices.

Abstract: Systems and methods for determining lighting fixture arrangement information (e.g., position and/or orientation). A lighting beam from the lighting fixture is directed among three discrete locations on a reference surface (e.g., by a controller). The fixture's position is determined using perspective inversion based on angular changes of the lighting fixture and coordinate data of the discrete locations (e.g., determined using a camera and a reference point on the surface). Distances from the fixture to the three discrete locations are estimated based on perspective inversion. The position of the lighting fixture is trilateralized based on the distances. Spherical coordinates of the fixture's orientation relative to the reference surface are determined, and yaw, pitch, and roll of the fixture are extracted.

Abstract: A method of surveying a venue includes scanning at least a portion of the venue using an unmanned aerial vehicle having at least one scanner, converting scan data gathered by the at least one scanner into three-dimensional location data, displaying the three-dimensional location data as a three-dimensional model, analyzing the three-dimensional model, and designating portions of the three-dimensional model with semantic mapping.

Abstract: Methods and systems for generating a lighting design for a venue. A lighting visual is selected. The lighting visual may be based on a different venue or a generated image. An electronic processor converts the lighting visual into lighting visual parameters. The processor receives mounting locations for lighting fixtures at the venue. A database of candidate lighting fixtures is accessed and a lighting design is generated that includes an arrangement of lighting fixtures and indicates which of the lighting fixtures is to be mounted in which location to produce a lighting effect at the venue that approximates the lighting visual. The lighting design may be based on multiple lighting visuals and corresponding visual parameters to produce multiple lighting effects at the venue that approximate the multiple visuals.

Abstract: Systems and methods for generating a three-dimensional model of a lighting fixture. The systems include a controller that includes an electronic processor coupled to a memory. The memory is configured to store instructions that when executed by the electronic processor configure the controller to receive first scanning data related to a lighting fixture while the lighting fixture is in a first configuration, receive second scanning data related to the lighting fixture after an adjustment to the lighting fixture to a second configuration, compare the first scanning data and the second scanning data, perform three-dimensional mesh reconstruction based on the first scanning data and the second scanning data, and generate the three-dimensional model based on the first configuration of the lighting fixture and the second configuration of the lighting fixture representing an operational capability of the lighting fixture.

Abstract: Systems and methods for controlling transitions in a lighting system based on a lighting graph. The system includes a light fixture, a controller, and a memory. The controller stores three or more lighting states and associates each with a respective lighting parameter for controlling the light fixture. Multiple input state transition paths and multiple output state transition paths are associated with each lighting state. The controller receives an input signal and determines an output state transition path that indicates a second lighting state of the three or more lighting states. The determination of the transition path is based on a condition or is unconditional. A light control signal is transmitted to the light fixture based on the respective lighting parameter associated with the second lighting state. A lighting state includes all of the parameters to execute the state, or parameters that define a difference from a prior lighting state.

Abstract: Systems and methods for generating a lighting design for a venue. The system includes a display device and a controller including an electronic processor connected to a memory. The memory stores instructions that when executed by the electronic processor configure the controller to receive object data based on a detected object in the venue, display the object data as a representation of the detected object in an interactive lighting environment, receive a user input via the interactive lighting environment to change lighting data that controls virtual lighting represented in the interactive lighting environment, and alter the virtual lighting represented in the interactive lighting environment based on the user input.

Abstract: A lighting fixture at a venue is controllable using augmented reality on a user-device that displays virtual elements on an image of the lighting fixture and/or a scene at the venue. User input for controlling the lighting fixture is received via the virtual elements and a signal is transmitted by the user device to alter the lighting fixture in the venue based on the user input. The virtual elements change in the display to reflect the change of state of the actual lighting fixture. Altering the lighting fixture includes changing brightness, color, or focus of light, or changing a position of the lighting fixture. The virtual elements may include a selection box around the lighting fixture, manufacturer data, channel numbers, DMX addresses, diagnostic information, a slider, a switch, a knob, a button, a virtual lighting shutter, pan/tilt axes, a moveable virtual beam of light, or a scenery element.
