Description

Technical Field

[0001] The present invention relates to a positioning data transmission system and a transmission method for identifying the spatial position information of a light-emitting device. More specifically, in an event space such as a concert hall, a sports stadium, a large-scale event, an exhibition hall, etc., the position information (for example, seat number or zone number of the standing zone, etc., hereinafter referred to as "spatial position information") of each participant who holds a light-emitting device (for example, "penlight") in the event space can be identified by each light-emitting device itself. The present invention relates to a system and a transmission method for transmitting positioning data for identifying the spatial position information of a light-emitting device to a plurality of light-emitting devices in an event space.

Background Art

[0002] The present invention relates to a technology in which a performer can generate various lighting patterns, that is, formations, in real time at a concert hall and transmit them to each light-emitting device (for example, a penlight) to perform a lighting show.

[0003] A formation is a concept similar to a light plot that means a lighting arrangement design in normal concert lighting. It means an operation of clustering the coordinates of light-emitting devices held by individual participants who participated in the concert hall into specific forms or patterns and configuring them so that each can be operated like a single lighting device.

[0004] The inventors have presented a "real-time dynamic crowd control system and method" in Korean Patent Application No. 10-2024-0068851, which generates and wirelessly transmits formation data in real time at a performance venue, enabling multiple light-emitting devices to simultaneously realize lighting effects. Unlike conventional light-emitting device control technologies that required pre-prepared data to be stored in light-emitting devices before the performance, this technology generates formation data in real time during the event and transmits it simultaneously to light-emitting devices within the event space. As a result, it has the advantage that the formation of lighting effects using light-emitting devices (such as penlights) in the event space can be changed and added in real time according to the atmosphere and situation at the venue.

[0005] However, such technologies for controlling multiple light-emitting devices had the inconvenience that each participant had to possess a smart device (for example, a smartphone with an app for controlling the light-emitting devices installed) to input the spatial location information of each light-emitting device.

[0006] Therefore, a method was needed that would allow the light-emitting devices to identify spatial location information without each participant having to input that information into a separate smart device for each device.

[0007] Furthermore, even when generating formation data before the start of a performance and transmitting it to the light-emitting devices, a method was still needed to enable each light-emitting device to identify its own spatial position for effective performance staging.

[0008] Korean Patent Application No. 10-2024-0068851 [Overview of the project] [Problems that the invention aims to solve]

[0009] The present invention has been made as needed, and aims to provide a system and transmission method for transmitting positioning data for spatial position identification of light-emitting devices to multiple light-emitting devices within an event space, such as a performance venue, sports stadium, large-scale event, or exhibition hall, so that each light-emitting device can identify the location information of each participant who possesses a light-emitting device within the event space. [Means for solving the problem]

[0010] To achieve the above objectives, a positioning data transmission system and a positioning data transmission / reception system including a plurality of light-emitting devices according to one embodiment, the positioning data transmission system for identifying the spatial position information of light-emitting devices in a performance venue, includes a master console that generates positioning data so that each of the plurality of light-emitting devices can identify its own spatial position information, a directional beam projector that projects a directional beam onto at least one target light-emitting device among the plurality of light-emitting devices that identifies its own spatial position information, and a positioning signal broadcaster that broadcasts a positioning signal modulated to include the positioning data to the plurality of light-emitting devices within the performance venue.

[0011] In this case, the master console may further include a data management unit that generates and stores the positioning data for at least one target light-emitting device for each sequence based on seat map data for the performance venue and spatial position information of each object within the performance venue; a directional beam control unit that generates a directional beam control signal to control the operation of the directional beam projector; and a positioning signal broadcaster control unit that generates a positioning signal broadcaster control signal to control the positioning signal broadcaster.

[0012] Furthermore, the object may include at least individual seats arranged in the performance venue, the directional beam projector, and the positioning signal broadcaster.

[0013] Furthermore, the directional beam control unit may transmit a trigger signal to the directional beam projector to initiate the spatial position information identification process of the target light-emitting device.

[0014] Furthermore, the positioning signal broadcaster control unit may transmit the positioning data to the positioning signal broadcaster for each sequence and control it so that the positioning signal is transmitted in a sequence synchronized with the directional beam.

[0015] Furthermore, the positioning signal may also be a radio frequency signal.

[0016] Furthermore, the directional beam projector may further include a beam modulator that modulates a directional beam based on a trigger signal transmitted from the directional beam control unit, a light source that emits the directional beam modulated by the beam modulator based on the trigger signal, and an optical system that adjusts the optical properties of the directional beam emitted by the light source.

[0017] Furthermore, the directional beam projector may further include a communication interface for receiving trigger signals, directional beam modulation signals, and directional beam control signals from the master console.

[0018] Furthermore, the directional beam projector may further include a directional beam actuator for moving the projection area of ​​the directional beam.

[0019] Furthermore, the directional beam may be a directional infrared beam.

[0020] Furthermore, the positioning data may include, as positioning data elements, at least a portion of the following: spatial position information of the directional beam projector, projection angle of the directional beam, beam projection distance from the directional beam projector to the target light-emitting device, intensity of the directional beam, arrival time of the directional beam, and unique identification value of the directional beam projector.

[0021] Furthermore, the positioning data may include at least one positioning data element in a particular sequence.

[0022] On the other hand, according to another embodiment, a method for transmitting positioning data for identifying the spatial position information of light-emitting devices in a performance venue by a positioning data transmission system including a master console, a directional beam projector, and a positioning signal broadcaster may include the steps of: the master console generating positioning data for at least one target light-emitting device to identify its own spatial position information; the master console generating a directional beam control signal for a target projection area of ​​a directional beam; the master console transmitting the positioning data to the positioning signal broadcaster for each sequence and generating a positioning signal broadcaster control signal to control the positioning signal broadcaster; the directional beam projector projecting the directional beam onto the target projection area based on the directional beam control signal; and the positioning signal broadcaster generating a positioning signal modulated to include the positioning data and broadcasting the positioning signal within the performance venue based on the positioning signal broadcaster control signal so as to be transmitted in a sequence synchronized with the directional beam.

[0023] In this case, the positioning data may be generated for each sequence based on the seat map data for the performance venue and the spatial position information of each object within the performance venue.

[0024] Furthermore, the step of projecting the directional beam onto the target projection area may further include: generating an infrared beam modulated such that a trigger signal for the directional beam projector to start identifying the spatial position information of the target light-emitting device is included based on the directional beam control signal; and adjusting the optical characteristics of the infrared beam by the directional beam projector based on the directional beam control signal so that the infrared beam has directivity.

[0025] Furthermore, the step of projecting the directional beam onto the target projection area may further include the step of moving the projection area of the directional beam by the directional beam projector based on the directional beam control signal.

[0026] Also, in the step where the master console generates positioning data for at least one target light-emitting device to identify its own spatial position information, when the spatial position calculation algorithm of the light-emitting device is a method of receiving spatial position information for a specific object and comparing the reception times to identify the spatial position information, the positioning data may include the spatial position information of the specific object as a positioning data element.

[0027] Alternatively, in the step where the master console generates positioning data for at least one target light-emitting device to identify its own spatial position information, when the spatial position calculation algorithm of the light-emitting device is a method of identifying spatial position information by performing an operation using trigonometric functions on the spatial position information and projection angle data of two directional beam projectors, the first spatial position information and the first projection angle of the first directional beam projector, and the second spatial position information and the second projection angle of the second directional beam projector may be included as positioning data elements.

[0028] Alternatively, in the step where the master console generates positioning data for at least one target light-emitting device to identify its own spatial position, if the spatial position calculation algorithm for the light-emitting device is a method of identifying spatial position information by performing calculations using trigonometric functions on the directional beam projection distance and projection angle data from the directional beam projector, the distance between the directional beam projector and the light-emitting device, and the projection angle of the directional beam projector may be included as positioning data elements. [Effects of the Invention]

[0029] According to the present invention, it is possible to realize a system and transmission method for transmitting positioning data for spatial position identification of light-emitting devices to multiple light-emitting devices within an event space, such as a concert hall, sports stadium, large-scale event, or exhibition hall, so that the position information of each participant possessing a light-emitting device within the event space can be identified by each light-emitting device.

[0030] Furthermore, since each participant possessing a light-emitting device can identify their own location within the event space, it becomes possible to control the subsequent flashing of the devices individually or in groups based on this information. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0032] The following describes in more detail an embodiment of a positioning data transmission system and transmission method for identifying the spatial position information of a light-emitting device, with reference to the drawings.

[0033] Throughout the specification and drawings, unless otherwise specified, each term is defined as follows:

[0034] Performance venue

[0035] Event spaces such as music venues, sports stadiums, large-scale events, and exhibition halls (hereinafter referred to as "performance venues"), broadly include spaces where seating, zones, or specific areas are clearly separated and organized.

[0036] Participants (audience)

[0037] "Participants" refers to individuals who are carrying their assigned light-emitting device within the performance venue.

[0038] Participant's location

[0039] "Participant location" refers to the physical space each participant actually occupies within the performance venue. This includes designated seats, specific points in standing zones, or other clearly demarcable spatial locations of participants, and refers to the actual location where the participant's light-emitting device is positioned.

[0040] Participant location information

[0041] "Participant location information" refers to a unique identifier or mark used to identify and distinguish the location of each participant within the performance venue. This can be expressed in the form of a seat number, zone identifier, combination of queues, or location indication within a standing zone. Throughout the specification and drawings, unless otherwise specified, participant location information has the same meaning as the location information of the light-emitting device assigned to that participant.

[0042] Spatial location information

[0043] Inside the performance venue, objects such as individual seats, directional beam projectors, positioning signal broadcasters, master systems, and light-emitting devices are arranged.

[0044] Spatial position information refers to information that indicates the actual physical location of each object within the performance venue within the actual space of the venue.

[0045] For example, the unique coordinate values ​​assigned to a seat with a specific seat number within a performance venue, within a coordinate system defined for that venue, can constitute spatial positional information for that seat.

[0046] Therefore, spatial position information can be used to indicate the physical location of each participant (or the light-emitting device assigned to each participant) within the performance venue.

[0047] Spatial location information broadly includes, but is not limited to, the data types exemplified in Table 1 below. 1. Numerical coordinate values ​​using a 2D or 3D coordinate system 2. Identifiers representing designated zones or sections within the performance venue. 3. Relative distance and direction from a specific reference point 4. Location code based on grid system 5. Angle and distance information using polar coordinates 6. Vector representation in 3-dimensional space 7. Explanation of the relative location based on major landmarks within the performance venue. 8. Traditional seat numbering system 9. Relative position expressed as a percentage of the size of the performance venue. 10. Location data obtained through various technologies such as depth sensors, RFID, Bluetooth beacons, and acoustic positioning.

[0048] Spatial location information can be represented in a single format or in combination of multiple formats, and the most suitable format can be selected or converted depending on the structure of the performance venue, the purpose of use, and the technical requirements.

[0049] Furthermore, spatial positional information is used to accurately determine the location of light-emitting devices, group them, and control them individually, enabling diverse and sophisticated performance productions.

[0050] Positioning data

[0051] Positioning data refers to all data necessary to identify the spatial position of an object (e.g., a light-emitting device) within a performance venue. "Identifying" spatial position information broadly includes deriving a result value calculated using established rules and algorithms, verifying given spatial position information, and determining a specific value as spatial position information after approximate calculation and / or inference.

[0052] Positioning data can be transmitted to each light-emitting device via transmitters within the performance venue. The positioning data may include spatial reference information. Furthermore, the positioning data may include parameters related to the transmitter, namely parameters related to the directional beam projector and parameters related to the positioning signal broadcaster. In addition, the positioning data may include other additional information used to identify the spatial position information.

[0053] Spatial reference information may include positioning data elements such as the following: - Spatial location information itself for a specific location (e.g., coordinate data) - Spatial position information of reference points within the performance venue - Information regarding the structure and seating arrangement of the performance venue. -Location data of major landmarks within the performance venue -Spatial location information - Information regarding the logical structure of the performance venue (For example, grid systems and zoning)

[0054] The parameters related to the transmitter may include the following positioning data elements. - Spatial position information of the infrared (IR) transmitter (e.g., coordinate data of the IR transmitter) - Beam projection angle of IR transmitter - Beam projection distance between IR transmitter and specific light-emitting device -IR signal strength - IR beam projection duration -When multiple IR transmitters are used, the unique identification information and related data of each IR transmitter

[0055] Other additional information may include the following positioning data elements. - Correction coefficient required for calculations performed by light-emitting devices to identify their own spatial position information. - Positioning algorithm parameters - Information necessary for calculations and / or corrections that other light-emitting devices perform to identify their own spatial position information.

[0056] In other words, the positioning data necessary for a light-emitting device to identify its own spatial position includes, specifically, the positioning data elements shown in Table 2 below.

[0057] [Table 1]

[0058] The positioning data may consist of only one positioning data element or may consist of multiple positioning data elements, depending on various factors such as the calculation algorithm used to identify spatial position information ("spatial position calculation algorithm"), the characteristics of the performance venue, and the required accuracy.

[0059] The positioning data is used by light-emitting devices within the performance venue, which receive the directional beam (e.g., directional infrared beam) and positioning signal (e.g., positioning RF signal) of the positioning data transmission system, to identify their own spatial position.

[0060] More specifically, when a directional infrared beam is projected onto a specific light-emitting device within the performance venue, the light-emitting device initiates a procedure to identify its own spatial position information in response to a trigger signal contained in the directional infrared beam. That is, the light-emitting device demodulates the broadcasted positioning signal to extract positioning data for that sequence, and then identifies its own spatial position information by performing calculations using a predetermined spatial position calculation algorithm based on the positioning data.

[0061] In other words, unlike conventional technology, even if spatial location information is not provided to the light-emitting device by an external device (for example, each participant's smartphone with an app for configuring the light-emitting device installed) or by pre-configuration work on each light-emitting device, according to the present invention, the light-emitting device can identify its spatial location information in real time.

[0062] Spatial position calculation algorithm

[0063] A spatial position calculation algorithm is a general term referring to the calculation methods used by light-emitting devices to identify their own spatial position using positioning data.

[0064] The spatial position calculation algorithm is built into the data storage device (e.g., memory) of each light-emitting device.

[0065] The spatial position calculation algorithm can be adapted to the characteristics of the performance venue, the type of transmitter used, the required accuracy, etc., by selecting an appropriate method or using a combination of multiple methods.

[0066] Each light-emitting device has multiple pre-configured spatial position calculation algorithms to suit various needs such as the characteristics of the performance venue, the type of transmitter used, and the required accuracy. The light-emitting device can identify spatial position information by appropriately selecting or combining the spatial position calculation algorithms that are appropriate for its needs.

[0067] Figure 1 shows an example of a positioning data transmission system for identifying the spatial position of a light-emitting device.

[0068] As shown in Figure 1, the positioning data transmission system 10, together with multiple light-emitting devices 20 in the performance venue, constitutes a positioning data transmission and reception system 1 for spatial position information identification, and provides positioning data to each light-emitting device 20a, 20b so that it can identify its own spatial position information.

[0069] The positioning data transmission system 10 comprises a master console 100, a directional beam projector 120, and a positioning signal broadcaster 140.

[0070] The directional beam projector 120 projects a directional beam onto at least one of the light-emitting devices 20a, 20b, which are held by each participant in the performance venue (used throughout the specification as equivalent to "assigned to each participant" and not necessarily meaning that they must be in contact with the participant's body).

[0071] The directional beam transmits a trigger signal that the light-emitting device 20a, which is the target of the beam, uses to identify its spatial position.

[0072] For this reason, the trigger signal is modulated into a form suitable for the characteristics of the directional beam. For example, when the trigger signal is pulse-width modulated (PWM) and included in a directional infrared beam, the trigger signal is first modulated into a signal with a constant pattern (pulse width). Then, the directional infrared beam is output in a blinking manner, turning on and off according to the pattern of the modulated trigger signal.

[0073] The trigger signal is used as a signal (trigger) to initiate the process of identifying its own spatial position information in the light-emitting device 20a. The directional beam must have directionality (collimation) so that it is projected only onto a specific area within the performance venue and the trigger signal is selectively provided only to the light-emitting devices 20a belonging to that area. As long as these conditions are met, the directional beam may be light (e.g., infrared), sound waves (e.g., ultrasound), or radio waves.

[0074] On the other hand, instead of having a single directional beam projector 120 project a directional beam to all areas within the performance venue, a combination of two or more directional beam projectors, each responsible for a portion of the performance venue, may be used to project a directional beam to all areas within the venue.

[0075] As an example of a directional beam projector 120, a so-called "moving light" or "moving head" (hereinafter referred to as "moving light") equipped with a directional beam light source can be considered. By using a moving light, the directional beam light source can be moved at a desired speed by an actuator that is electrically / mechanically driven according to a control signal, and the size of the projection area can also be adjusted.

[0076] Another example of the directional beam projector 120 is a method that controls the directional beam light source using DLP (Digital Light Processing), LCOS (Liquid Crystal on Silicon), SLM (Spatial Light Modulator), etc.

[0077] In particular, this includes cases where a high-power, highly directional infrared light source, such as an infrared laser, is used as the directional beam light source.

[0078] For example, the DLP (Digital Light Processing) method uses a micromirror array to control the reflection of the laser beam, resulting in high compatibility with laser light sources and excellent resistance to the heat of infrared lasers.

[0079] LCOS (Liquid Crystal on Silicon) is a method that uses reflective liquid crystals to control the beam light source and is suitable for lasers in the infrared wavelength band.

[0080] A Spatial Light Modulator (SLM) is a device that can precisely adjust the phase and intensity of a laser beam, and can therefore be used when high-precision control of an infrared laser beam source is required.

[0081] A directional beam, modulated to transmit a trigger signal, is projected onto a light-emitting device 20a within the target projection area in synchronization with a sequence of positioning signals. Various methods are possible, as needed, including a method in which the directional beam sequentially scans the entire target projection area, or a method in which the directional beam moves across the projection area to form a specific pattern. The trigger signal is used as an important temporal and spatial reference in the spatial position calculation algorithm.

[0082] The positioning signal broadcaster 140 broadcasts a positioning signal, which is a modulated signal containing positioning data, within the performance venue, thereby ensuring that a single piece of positioning data is simultaneously provided to all light-emitting devices 20a and 20b within the performance venue.

[0083] The basic concept of positioning data is as described above.

[0084] The positioning signal broadcaster 140 can be, for example, a radio frequency transmitter (RF transmitter). More specifically, it could be an RF transmitter in the 2.4GHz radio frequency band used for Bluetooth, Zigbee, or Wi-Fi, but as long as the condition that the radio frequency signal containing the positioning data must be broadcast to all light-emitting devices in the performance venue is met, the positioning signal broadcaster 140 can use a wide range of frequency bands, modulation schemes, and communication protocols, and can use a radio frequency signal containing positioning data.

[0085] The master console 100 generates positioning data based on seat map data and spatial position information for objects within the performance venue.

[0086] Spatial position information refers to information that indicates the actual physical location of physical objects present within the performance venue within the actual space of the venue, as described above.

[0087] A seat map refers to the correspondence between seat numbers in a performance venue and the actual seats within the venue. Therefore, seat map data can be represented in the form of a data table that shows the correspondence between seat numbers in a performance venue and the actual seats within the venue.

[0088] Furthermore, the seat map may also include the correspondence between zone numbers within the performance venue (for example, numbers assigned to each standing zone in a standing concert venue, or numbers assigned collectively to multiple seats in a specific area of ​​the performance venue) and the actual zones within the venue. Therefore, the seat map data may also include a data table relating the correspondence between zone numbers and the actual zones within the performance venue.

[0089] Sheet map data and spatial position information are input from an external sheet map data generator 30 connected to the positioning data transmission system 10. The sheet map data generator 30 generates, stores, and manages sheet map data and spatial position information for objects within the performance venue.

[0090] According to one embodiment, the sheet map data generator 30 may be integrated as part of the positioning data transmission system 10, or as part of the master console 100.

[0091] Meanwhile, a positioning signal (e.g., RF) modulated to include positioning data is transmitted from the positioning signal broadcaster 140 to all light-emitting devices 20a and 20b within the performance venue.

[0092] The master console 100 controls the positioning signals to precisely synchronize with the sequence of directional beams projected from the directional beam projector 120.

[0093] Figure 2 is a block diagram of the master console of the positioning data transmission system.

[0094] The embodiment shown in Figure 2 illustrates a case in which a directional infrared beam light source is used for the directional beam projector 120 of the positioning data transmission system 10, and a transmitter that broadcasts RF radio frequency signals in the 2.4 GHz band is used for the positioning signal broadcaster 140.

[0095] As shown in Figure 2, the master console 100 includes a data management unit 102, a directional beam control unit 104, a positioning signal broadcaster control unit 106, and an interface unit 108.

[0096] The data management department 102 has three main roles.

[0097] (1) Store and manage seat map data for seats in the performance venue and spatial position information for objects within the performance venue.

[0098] (2) For each sequence, positioning data that must be transmitted to that sequence is set. As described above, the positioning data includes at least one positioning data element.

[0099] (3) Positioning data for each sequence is transmitted to the positioning signal broadcaster control unit 106 and used to generate the positioning signal broadcaster control signal. As a result, the sequence of the trigger signal transmitted via the directional beam and the positioning data transmitted via the positioning signal are strictly synchronized.

[0100] The directional beam control unit 104 has two main functions.

[0101] (1) Generate a trigger signal and transmit it to the directional beam projector. The trigger signal is transmitted via the directional infrared beam to the light-emitting device in the target projection area, allowing the light-emitting device to recognize the directional infrared beam and initiate its own spatial position information identification process.

[0102] (2) The operation of the directional beam projector 120 (direction of movement, speed of movement, projection angle, beam size, etc.) is controlled so that the directional infrared beam is projected onto the target projection area within the performance venue at the scheduled time. If the optical system of the directional beam projector 120 includes a lens system and an aperture system, the lens system and the aperture system can be controlled to adjust the projection range of the directional infrared beam.

[0103] In this regard, the rotational motion of a directional beam actuator can be controlled to sequentially move the projection point of the directional infrared beam in synchronization with a sequence of positioning signals broadcast within the performance venue.

[0104] The positioning signal broadcaster control unit 106 performs three main functions.

[0105] (1) Positioning data including directional beam-related parameters is generated for each sequence.

[0106] (2) The generated positioning data is transmitted to the positioning signal broadcaster 140, causing the positioning signal broadcaster 140 to generate a positioning signal (for example, a signal in the radio frequency band) that is modulated to include the positioning data.

[0107] (3) A positioning signal broadcaster control signal is generated, thereby controlling the operation of the positioning signal broadcaster 140 so that the positioning signal is broadcast to light-emitting devices in the performance venue in synchronization with the directional infrared beam of the same sequence.

[0108] The interface unit 108 further includes an input / output interface unit 1081 and a communication interface unit 1082.

[0109] The input / output interface unit 1081 includes an input interface device (e.g., keyboard, mouse, touchscreen, microphone, various sensor devices, etc.) for receiving commands from the user for the operation of the positioning data transmission system 10 and the master console 100. It also includes an output interface device (e.g., display, speaker, lamp, etc.) for displaying the operating status of the positioning data transmission system 10 and the master console 100.

[0110] The communication interface unit 108 is responsible for transmitting signals and data that are input to or output from the master console 100. For example, when sheet map data and spatial position information are generated by the sheet map data generator 30 outside the master console 100, they are input to the positioning data transmission system 10 via the input / output interface unit 1081. In addition, positioning data, positioning signal broadcaster control signals, directional beam control signals, etc., generated by the master console 100 can be transmitted to the directional beam projector 120 and the positioning signal broadcaster 140. Depending on the embodiment, the communication interface unit 108 can be appropriately selected from various types of wired communication modules that perform wired communication and various types of wireless communication modules that perform wireless communication.

[0111] Figure 3 shows an example of a directional beam projector in a positioning data transmission system.

[0112] Similar to Figure 2, Figure 3 also illustrates the case where an infrared light source is used in the directional beam projector 120 of the positioning data transmission system 10.

[0113] The directional beam projector 120 illustrated in Figure 3 includes a beam modulator 1200, an infrared light source 1210, an optical system 1220, and a directional beam actuator 1230.

[0114] The beam modulator 1200 modulates the directional infrared beam (e.g., PWM modulation) based on a trigger signal transmitted from the directional beam control unit 104. Meanwhile, the light-emitting devices 20a and 20b, which receive the directional beam, demodulate the trigger signal embedded in the directional beam and begin their own spatial position information identification process.

[0115] The infrared light source 1210 generates a directional infrared beam that is modulated by the beam modulator 1200 based on a trigger signal.

[0116] The infrared light source 1210 is a device that generates light in the infrared wavelength range (approximately 700 nm to 1 mm).

[0117] In particular, infrared light sources used in directional beam projectors must emit a directional infrared beam focused in a specific direction and possess high consistency and efficiency. Therefore, the following types of infrared light sources can be primarily considered.

[0118] (1) Infrared laser diode (IR Laser Diode)

[0119] Features: Emits high-power infrared beams at specific wavelengths (e.g., 808nm, 980nm, 1550nm, etc.), generating highly directional and consistent light waveforms.

[0120] Application fields:

[0124] Advantages: Generates a small, low-power, and highly efficient infrared beam.

[0125] (2) Infrared light-emitting diode (IR LED)

[0126] Features: Similar to a typical LED, but emits light in the infrared band (700nm~1mm), and when combined with a special lens, the beam can be focused in a specific direction.

[0127] Application fields:

[0128] - Remote control: Control of televisions and electronic devices

[0129] - Sensors: Infrared distance measurement, proximity sensor

[0130] -Vision system: Vehicle driving support system

[0131] - Limitations: Lower directivity and output compared to laser diodes.

[0132] The optical system 1220 modifies the characteristics of the directional infrared beam generated by the infrared light source 1210 so that the directional infrared beam has even stronger directivity. To this end, the optical system 1220 consists of a combination of lenses, mirrors, filters, etc., designed to suit the application and purpose.

[0133] For example, a collimator lens among the lenses aligns the infrared beam generated from an infrared diode or infrared LED in parallel. That is, the directional infrared beam generated from the infrared light source 1210 can have its directivity and density further enhanced as it passes through the optical system 1220.

[0134] The infrared light source 1210 and the optical system 1220 determine characteristics such as the size and intensity of the directional infrared beam in response to the directional beam control signal.

[0135] The directional beam actuator 1230 plays a role in moving the projection area of ​​the directional infrared beam.

[0136] The directional beam actuator 1230 can be a three-axis actuator driven by an electric motor. That is, as mentioned above, as an example of the directional beam projector 120, a so-called "moving light" or "moving head" (hereinafter referred to as "moving light") equipped with an infrared light source 1210 can be considered. By using a moving light, the directional beam light source can be moved to a desired speed by an actuator that is electrically / mechanically driven according to a control signal, and the size of the projection area can also be adjusted.

[0137] Figure 4 shows an example of a method for transmitting positioning data for identifying the spatial location of light-emitting devices within a performance venue.

[0138] As shown in Figure 4, a method for transmitting positioning data for light-emitting devices within a performance venue, performed by a positioning data transmission system including a master console, a directional beam projector, and a positioning signal broadcaster, includes the steps of: generating positioning data (S100); generating a directional beam control signal (S110); generating a positioning signal broadcaster control signal (S120); projecting a directional beam onto a target projection area (S130); and broadcasting a positioning signal within the performance venue (S140).

[0139] In the step of generating positioning data (S100), the master console generates the positioning data. The positioning data is used by at least one target light-emitting device to identify its own spatial position. The positioning data may be generated for each sequence based on seat map data for the performance venue and the spatial position information of each object within the performance venue.

[0140] The seat map data generator maps information about the location of all objects within the performance venue (e.g., participants, light-emitting devices assigned to participants, master console, directional beam projector, positioning signal broadcaster, etc.) configured according to the venue's layout (e.g., seat number of a specific seat) to spatial location information. It also generates and stores a seat map containing the spatial location information mapped to each object within the performance venue.

[0141] On the other hand, if the master console includes a component for generating seat map data, a step (S102) may be performed before the step (S100) for generating positioning data, in which case seat map data for the performance venue and spatial position information for each object within the performance venue may be performed.

[0142] Alternatively, if the master console receives sheet map data for the performance venue and spatial position information for each object within the performance venue from an external sheet map data generator, a step (S104) in which the sheet map data for the performance venue and spatial position information for each object within the performance venue are received from the external sheet map data generator may be performed before the step (S100) in which the positioning data is generated.

[0143] In the step of generating a directional beam control signal (S110), the master console generates a directional beam control signal for the target projection area of ​​the directional beam. The directional beam control signal may be generated based on the directional beam projection path and beam travel time.

[0144] For example, the master console can read a seat map and spatial position information, and generate positioning data based on the spatial position information.

[0145] In this case, the master console may set the travel path and travel time for the directional beam's target projection area on the seat map according to the layout of the performance venue. The master console may also set a sequence in which a positioning signal modulated to include positioning data is broadcast in accordance with the spatial position information of each participant (i.e., the light-emitting device assigned to the participant) belonging to the travel path of the target projection area.

[0146] In step (S120), which generates a positioning signal broadcaster control signal, the master console transmits positioning data to the positioning signal broadcaster for each sequence and generates a positioning signal broadcaster control signal.

[0147] In the step of projecting a directional beam onto a target projection area (S130), the directional beam projector projects a directional beam onto the target projection area based on the directional beam control signal. This step may further include the step of generating an infrared beam that is modulated (e.g., pulse-width modulated (PWM)) so that the directional beam control signal includes a trigger signal. The trigger signal is used by the target light-emitting device that receives it to initiate a spatial position information identification process. The step of projecting a directional beam onto a target projection area (S130) may further include the step (not shown) in which the directional beam projector adjusts the optical properties of the infrared beam based on the directional beam control signal so that the infrared beam is directional.

[0148] The step of projecting a directional beam onto a target projection area (S130) may further include a step (not shown) in which the directional beam projector moves the projection area of ​​the directional beam based on a directional beam control signal. For example, the directional beam actuator of the directional beam projector may move the projection area of ​​the directional beam based on a directional beam control signal. The target projection area projected by the directional beam projector can be moved along a freely set path on a coordinate system mapped to the performance venue.

[0149] In step (S140), which involves broadcasting a positioning signal within the performance venue, a positioning signal broadcaster broadcasts the positioning signal within the venue so that it is transmitted in a sequence synchronized with the directional beam based on the positioning signal broadcaster control signal. In this step, the positioning signal broadcast in synchronization with the directional beam in a particular sequence may include positioning data elements relating to the direction of movement of the directional beam in that sequence, and positioning data elements relating to the movement time of the directional beam.

[0150] On the other hand, the method for a light-emitting device to identify its own spatial position, i.e., the spatial position calculation algorithm, can be designed in a variety of ways. In this case, the positioning data elements that must be included in the positioning data may differ depending on the spatial position calculation algorithm.

[0151] For example, the following can be considered as spatial position calculation algorithms.

[0152] Spatial position calculation algorithm

[0153] Algorithm 1) A method for identifying spatial location information by receiving spatial location information for a specific object and comparing the reception times.

[0154] Algorithm 2) A method for identifying spatial position information by receiving spatial position information and projection angle data of a directional beam projector and performing calculations using trigonometric functions on these positioning data elements.

[0155] Algorithm 3) A method for identifying spatial position information by receiving directional beam projection distance and projection angle data from a directional beam projector and performing calculations using trigonometric functions on these positioning data elements.

[0156] The positioning data elements that are always required for the positioning data in each of these three spatial position calculation algorithms are summarized in Table 3 below.

[0157] [Table 2]

[0158] In addition to the three spatial position calculation algorithms mentioned above, there may be various other algorithms that utilize positioning data elements to enable light-emitting devices to identify their own spatial position information.

[0159] On the other hand, the spatial position calculation algorithm can be programmed to be included in the program for identifying spatial position information, and then embedded in the memory of each light-emitting device.

[0160] The program for identifying spatial location information, which embodies the spatial location calculation algorithm, is usually embedded in the memory of each light-emitting device before the performance. However, it is also possible for it to be downloaded in real time during the performance using methods such as OTA (On-The-Air) and then stored in the memory of each light-emitting device.

[0161] In this way, when each light-emitting device identifies its own spatial position information, a central control system for performance effects can control the light-emitting state of each light-emitting device individually or in groups based on the spatial position information of each device, thereby realizing various lighting effects within the performance venue. For example, by utilizing the technology exemplified in the inventor's Korean Patent Application No. 10-2024-0068851, diverse lighting effects can be realized in real time within the performance venue.

[0162] In particular, the present invention offers unique advantages such as the ability to quickly and accurately determine the spatial position information of large-scale light-emitting devices "without participant intervention," and the ability to update the spatial position information of each light-emitting device in real time during a performance, enabling dynamic performance productions.

[0163] Figure 5 shows an example of a light-emitting device.

[0164] As shown in Figure 5, the light-emitting device 20 includes an IR receiver 200, an RF receiver 210, a memory 220, a processor 230, a light-emitting unit 240, and a power supply 250.

[0165] The light-emitting device 20 is an electrically powered light-emitting device that is held by audience members at performance venues. The light-emitting device 20 can be implemented in various forms, such as LED penlights and LED wristbands.

[0166] The light-emitting device 20 can perform various performance effects by changing its illumination state under the control of a central control system for performance effects. The central control system for performance effects may be integrated with the positioning data transmission system 10, or it may be implemented as a separate control system connected to the positioning data transmission system 10 by wired or wireless means.

[0167] The light-emitting device 20 receives a positioning signal (e.g., an RF signal) and a directional beam (e.g., a directional infrared beam) transmitted from the positioning data transmission system 10, demodulates the positioning signal and directional beam to extract positioning data and a trigger signal, respectively, and then identifies its own spatial position information according to a spatial position calculation algorithm based on the positioning data and trigger signal.

[0168] The embodiment shown in Figure 5 describes a light-emitting device in which a 2.4 GHz band RF signal is used as the positioning signal and a directional infrared beam is used as the directional beam.

[0169] The IR receiver 200 recognizes the directional infrared beam projected by the directional beam projector 120. For example, an infrared sensor can be used as the IR receiver 200.

[0170] The IR receiver 200 further includes an IR demodulator 202. The IR demodulator 202 demodulates the infrared beam and extracts a trigger signal according to a control program stored in the processor 230 and memory 220.

[0171] The RF receiver 210 receives positioning signals broadcast within the performance venue. For example, a Zigbee receiver that receives RF signals in the 2.4GHz band can be used as the RF receiver 210. However, even when using a Zigbee receiver, it is not necessary to use the Zigbee communication protocol as the communication protocol.

[0172] The RF receiver 210 further includes an RF demodulator 212. The RF demodulator demodulates the positioning signal and extracts positioning data for each sequence according to a control program stored in the processor 230 and memory 220.

[0173] Memory 220 stores control programs, spatial position calculation algorithms, performance production data, etc. It can also store positioning data. Furthermore, it can temporarily store data calculated by the spatial position information calculation algorithm. A wide variety of types and methods of memory suitable for these purposes can be widely used for memory 220.

[0174] The processor 230 controls the IR receiver 200, RF receiver 210, IR demodulator 202, RF demodulator 212, and light-emitting unit 240 according to a control program stored in the memory 220. The processor 230 also identifies the spatial position information of the light-emitting device 20 using a spatial position calculation algorithm, trigger signals, and positioning data. Furthermore, by controlling the blinking state of the light-emitting unit 240 (on, off, brightness, duration, etc.) according to the performance effect data, the processor ensures that the intended performance effect is achieved within the performance venue.

[0175] The light-emitting unit 240 operates to blink (on, off, brightness, duration, etc.) under the control of the processor 230. The light-emitting unit 240 can use light-emitting diodes (LEDs), but a wide variety of lighting elements and lighting devices that can be used for the purpose of obtaining performance effects can also be used.

[0176] The power supply 250 supplies power to the light-emitting device 20. Since it is often embodied in the form of an LED penlight or LED wristband held by the audience, the power supply 250 can use a rechargeable battery and its charging control circuit. However, a wide variety of power supply means (batteries, AC power supply for wired power supply, miniature power devices, etc.) can be used to supply power to the light-emitting device 20.

[0177] Figures 6A and 6B illustrate the first algorithm, which is a spatial position calculation algorithm related to a method in which a light-emitting device in a performance venue receives spatial position information for a specific object and identifies the spatial position information by comparing the reception times.

[0178] Depending on the spatial position calculation algorithm used by the light-emitting device, one or more positioning data elements that must be included in the positioning data for the master console to identify its own spatial position information by at least one target light-emitting device are specifically identified.

[0179] In order for the light-emitting devices within the performance venue to identify spatial position information according to the first algorithm, the positioning data element must necessarily include "spatial position information of a specific object," as shown in Table 2.

[0180] To this end, the positioning data transmission system broadcasts a positioning signal, which includes the spatial position information of a specific object as a positioning data element, to light-emitting devices within the performance venue through the following specific process.

[0181] Step 1.

[0182] The seat map data generator maps the positional information (which may include seat numbers, etc.) of all objects within the performance venue (individual seats, master console, directional beam projector, positioning signal broadcaster, and other objects with defined positions) that are configured according to the venue's layout, to coordinate values ​​in the coordinate system used by the seat map data generator.

[0183] The sheet map generated by the sheet map data generator includes the location information and corresponding coordinate values ​​of all objects within the performance venue. Depending on the case, the sheet map may also include information about the type of coordinate system used in the sheet map (e.g., plane orthogonal coordinate system, spatial orthogonal coordinate system, plane polar coordinate system, spatial polar coordinate system, etc.).

[0184] Figure 6A shows the case where a sheet map is generated using an XY plane orthogonal coordinate system that has an X axis (horizontal axis) and a Y axis (vertical axis).

[0185] Step 2.

[0186] The master console reads system data generated by the seat map data generator (which may be an external device or a component integrated into the master console) and spatial position information of all objects within the performance venue into the data management unit.

[0187] Step 3.

[0188] Depending on the layout of the performance venue, the master console inputs the movement paths and travel times for the X and Y axes of the target projection area of ​​the directional beam projector on the seat map.

[0189] Step 4.

[0190] The master console sets the range and sequence of coordinate values ​​broadcast by the positioning signal broadcaster, corresponding to the position of each object (e.g., a seat) belonging to the movement path of the directional beam projector's target projection area.

[0191] The target projection area of ​​the directional beam projector can be moved, for example, in the X-axis and Y-axis directions.

[0192] (1) In the case of X-axis coordinate transmission, under the control of the master console, the directional beam projector projects a directional beam while moving the trajectory of the directional beam in the left and right directions along the X-axis path. Simultaneously, the positioning signal broadcaster broadcasts a sequence of X-axis coordinate values ​​at regular time intervals in synchronization with the movement of the directional beam trajectory. Light-emitting devices included in the directional beam trajectory detect the directional infrared beam with an IR receiver and the positioning signal with an RF receiver, and identify their own X-axis coordinate values ​​by demodulating the trigger signal and positioning data at the time of recognition and applying a spatial position calculation algorithm. The identified X-axis coordinate values ​​are stored in the memory of the light-emitting device.

[0193] (2) In the case of Y-axis coordinate transmission, under the control of the master console, the directional beam projector projects a directional beam while moving the trajectory of the directional beam vertically along the Y-axis path. Simultaneously, the positioning signal broadcaster broadcasts a sequence of Y-axis coordinate values ​​at regular time intervals in synchronization with the movement of the directional beam trajectory. Light-emitting devices included in the directional beam trajectory detect the directional infrared beam with an IR receiver and the positioning signal with an RF receiver, and identify their own Y-axis coordinate values ​​by demodulating the trigger signal and positioning data at the time of recognition and applying a spatial position calculation algorithm. The identified Y-axis coordinate values ​​are stored in the memory of the light-emitting device.

[0194] On the other hand, depending on the size, structure, and arrangement of the performance venue, one or more directional beam projectors can be installed and used in a performance venue to cover the entire target projection area, as needed. When using two or more directional beam projectors, the transmission of X and Y axis coordinate data can be performed by dividing the target projection area into multiple zones depending on the size, structure, and arrangement of the performance venue, and each directional beam projector responsible for a zone can project a directional beam within that zone.

[0195] Figure 6A illustrates a case where a directional beam projector projects a directional infrared beam by moving the trajectory of the directional beam from A to B in the X-axis direction for a certain period of time (T1-T0).

[0196] The shaded circular areas AB1 and AB2 represent the target projection areas of a directional beam, each with a radius R1. For a certain period of time (T1-T0), the directional beam moves along a trajectory with areas AB1 and AB2, and the area AB12 between them, as its target projection areas.

[0197] For convenience, let T0 be the time when the rightmost point of the directional beam's projection area is at point A, and T1 be the time when the leftmost point of the directional beam is at point B.

[0198] Figure 6B illustrates a sequence of X-axis coordinate values.

[0199] The data sequence shown in Figure 6B is a sequence of X-axis coordinate values ​​to be assigned to objects within the trajectory of the target projection area from time (T0) to time (T1). This data sequence, or positioning data element, includes the corresponding X-axis coordinate value for each seat number on the seat map.

[0200] Referring to Figure 6A, in an embodiment in which X-axis coordinate values ​​are transmitted to light-emitting devices located in seats (C1-C31) in "Row C", the following conditions can be considered to explain a specific method for calculating the X-axis coordinate values.

[0201] - Distance between A and B: 1,550 cm -Seat spacing: 50cm -Total number of seats: 31 seats (C1~C31) - Directional infrared beam diameter (2 × R1): 200 cm -Modulation frequency of directional infrared beam: 38kHz -The travel time (T1-T0) from point A to point B for the rightmost point of the directional infrared beam's projection area to point B is 30 seconds. -Data sequence of X-axis coordinate values ​​broadcast during travel time (T1-T0): Figure 6B

[0202] For example, the process by which the light-emitting device of seat (C24) identifies its own X-axis coordinate value according to the first algorithm is as follows:

[0203] Step 1

[0204] (1) If the diameter of the directional infrared beam in the target projection area is 200 cm, the number of seats per projection area is 4.

[0205] (2) When the directional infrared beam moves along the trajectory under the above conditions, the projection time of the directional infrared beam assigned to each seat is an average of 0.97 seconds (30 seconds / 31 seats). Therefore, seat (C24) receives the beam for approximately 3.88 seconds (0.97 seconds × 4).

[0206] (3) At this time, when the seat (C24) light-emitting device demodulates the positioning signal it has received, it becomes positioning data that includes X-axis coordinate values ​​(X23, X24, X25, X26) as positioning data elements. The seat (C24) light-emitting device can determine the coordinate value (X24) of the sequence corresponding to the midpoint between the time (T2) when the directional infrared beam was first detected and the time (T3) when it was last detected as its own coordinate value. However, a modified embodiment is also possible in which the coordinate value of the sequence corresponding to a different point in time is determined as the coordinate value instead of the midpoint time. For example, the midpoint value, average value, etc. of the X-axis coordinate value data sequence received in synchronization with the directional infrared beam can be made to approximate the actual spatial position information. Therefore, a wide range of calculation methods can be used to calculate values ​​that are close to the actual spatial position information.

[0207] The method for determining the Y-axis coordinate values ​​according to the first algorithm can be performed in the same way as the method for determining the X-axis coordinate values.

[0208] Through this process, the light-emitting device of the seat (C24) can identify its own spatial position information, consisting of a pair of X-axis and Y-axis coordinate values, on the XY plane Cartesian coordinate system using the first algorithm.

[0209] Figure 7 illustrates a second algorithm, which is a spatial position calculation algorithm related to a method for identifying spatial position information by receiving spatial position information and projection angle data of a directional beam projector and performing calculations using trigonometric functions on these positioning data elements.

[0210] In order for the light-emitting devices within the performance venue to identify spatial position information according to the second algorithm, the positioning data elements must include "spatial position information and projection angles of two directional beam projectors," as shown in Table 2.

[0211] In this scenario, the two directional beam projectors each project a directional infrared beam onto the same light-emitting device. The beam projection times to the same light-emitting device do not need to be identical.

[0212] To this end, the positioning data transmission system broadcasts a positioning signal to light-emitting devices within the performance venue through the following specific process, which includes the spatial position information (first spatial position information) and projection angle (first projection angle) of the first directional beam projector, and the spatial position information (second spatial position information) and projection angle (second projection angle) of the second directional beam projector as positioning data elements for the two directional beam projectors.

[0213] Step 1.

[0214] The seat map data generator maps the positional information (which may include seat numbers, etc.) of all objects within the performance venue (individual seats, master console, directional beam projector, positioning signal broadcaster, and other objects with defined positions) that are configured according to the venue's layout, to coordinate values ​​in the coordinate system used by the seat map data generator.

[0215] The sheet map generated by the sheet map data generator includes the position information and corresponding coordinate values ​​of all objects within the performance venue. Depending on the case, the sheet map may also include information about the type of coordinate system used in the sheet map (e.g., plane orthogonal coordinate system, spatial orthogonal coordinate system, plane polar coordinate system, spatial polar coordinate system, etc.).

[0216] Figure 7 shows the case where a sheet map is generated using an XY plane orthogonal coordinate system that has an X axis (horizontal axis) and a Y axis (vertical axis).

[0217] Step 2.

[0218] The master console reads system data generated by the seat map data generator (which may be an external device or an integrated component of the master console) and spatial position information of all objects within the performance venue into the data management unit.

[0219] Step 3.

[0220] Depending on the layout of the performance venue, the master console inputs the movement paths and travel times for the X and Y axes of the target projection area of ​​the two directional beam projectors on the seat map.

[0221] Step 4.

[0222] The master console sets a data sequence containing [coordinates of the first directional infrared beam projector, coordinates of the second directional infrared beam projector, first projection angle, and second projection angle] corresponding to the position of each object (e.g., a seat) located within the movement path of the target projection area of ​​the two directional beam projectors.

[0223] In the embodiment shown in Figure 7, the target projection area of ​​the first directional beam projector can be moved, for example, from left to right on the X-axis, and the target projection area of ​​the second directional beam projector can be moved in the opposite direction, from right to left on the X-axis.

[0224] (1) In the case of X-axis coordinate transmission, under the control of the master console, the first directional beam projector projects a directional beam while moving the trajectory of the directional beam from left to right along the X-axis path. The second directional beam projector projects a directional beam while moving the trajectory of the directional beam from right to left along the X-axis path.

[0225] (2) Simultaneously, the positioning signal broadcaster broadcasts a sequence of positioning signals containing [coordinate values ​​of the first directional infrared beam projector, coordinate values ​​of the second directional infrared beam projector, first projection angle, and second projection angle] in synchronization with the movement of the directional beam's trajectory. Light-emitting devices included in the trajectory of the directional beam detect the directional infrared beam with an IR receiver and the positioning signal with an RF receiver, demodulate the trigger signal and positioning data at the time of recognition, and apply a spatial position calculation algorithm. Therefore, when the beam of the first directional beam projector is detected, the coordinate values ​​of the first directional beam projector and the first projection angle can be identified. Also, when the beam of the second directional beam projector is detected, the coordinate values ​​of the second directional beam projector and the second projection angle can be identified. The identified coordinate values ​​of the first directional beam projector, the coordinate values ​​of the second directional beam projector, the first projection angle, and the second projection angle are stored in the memory of the light-emitting device.

[0226] Figure 7A shows a case where a first directional beam projector, positioned at point (D) within the performance venue with coordinate values ​​(x1, y1), projects a directional infrared beam at a projection angle (θ1), and a second directional beam projector, positioned at point (E) with coordinate values ​​(x2, y2), projects a directional infrared beam at a projection angle (θ2).

[0227] The shaded area (DF) shows the trajectory of the target projection area of ​​the first directional beam projector, and area (EF) shows the trajectory of the target projection area of ​​the second directional beam projector. Point (F) is the common area of ​​areas (DF) and (EF).

[0228] For example, according to the second algorithm, the process by which a light-emitting device of a seat located at point (F) identifies its own spatial position information (coordinate values ​​on the XY plane Cartesian coordinate system) is as follows:

[0229] Step 1

[0230] (1) The light-emitting device located at point (F) stores the coordinate values ​​of the first directional beam projector, the coordinate values ​​of the second directional beam projector, the first projection angle, and the second projection angle in its memory, as described above.

[0231] (2) As shown in Figure 7A, a triangle (DEF) is created by connecting points (D), (E), and (F) with an imaginary line. In this case, the interior angle of vertex (D) is the first projection angle (θ1), and the interior angle of vertex (E) is the second projection angle (θ2). Therefore, using the given data values ​​and trigonometric functions, the coordinates of point (F), that is, the coordinates of the light-emitting device placed at point (F), can be determined using trigonometric functions.

[0232] Figure 7B is a diagram illustrating how to determine the coordinates of a light-emitting device from a triangle (DEF).

[0233] The memory of the light-emitting device stores positioning data elements as shown in Table 4.

[0234] [Table 3]

[0235] The distance (l) between point (D) and point (E) can be calculated using equation 1.

[0236] [Formula 1]

number

[0237] If the distances between point (D) and point (F), and between point (E) and point (F), are r and s, respectively, then the distance (r) can be calculated using equation 2.

[0238] [Formula 2] l = DF + FE = r·cos(θ1) + s·cos(θ2), r = (l - s·cos(θ2)) / cos(θ1).

[0239] When the line segment connecting point (D) and point (E) is perpendicular to the line segment connecting point (F) and point (G), the distance (h) between point (F) and point (G) can be calculated using equation 3.

[0240] [Formula 3] h = r sin(θ1) = s sin(θ2), r = s·sin(θ2) / sin(θ1).

[0241] Using equations 2 and 3, the distance (s) can be calculated using equation 4.

[0242] [Equation 4] r = (l - s·cos(θ2)) / cos(θ1) = s·sin(θ2) / sin(θ1), therefore, s = l sin(θ1) / sin(θ2+θ2).

[0243] The angle (φ) that the line connecting points (D) and (E) makes with the x-axis can be found using equation 5, where (x1, y1) is the coordinate of point (D) and (x2, y2) is the coordinate of point (E).

[0244] [Formula 5]

number

number

[0245] Therefore, the coordinates (x3, y3) of the light-emitting device placed at point (F) can be determined by equation 6.

[0246] [Formula 6]

number

[0247] For example, in Figure 7A, when the spectator seats are mapped to an XY plane orthogonal coordinate system of the same scale, if the coordinates of the location (D) where the first directional beam projector is placed are (5, 1) and the first projection angle is 40.3 degrees, and the coordinates of the location (E) where the second directional beam projector is placed are (25, 1) and the second projection angle is 61.9 degrees, then the coordinate values ​​of the seats and light-emitting devices placed at location (F) will be (18, 81, 12, 68). Therefore, the light-emitting device at location (F) can be identified as having its own spatial position information (i.e., coordinate values ​​in the XY plane orthogonal coordinate system) as (19, 13).

[0248] The embodiment shown in Figure 7 illustrates the case where a plane orthogonal coordinate system with identical X and Y axis scales is used for the sheet map. However, depending on the performance venue, it may be possible to generate a coordinate system using an XY plane orthogonal coordinate system with different X and Y axis scales to suit the performance venue, taking into account factors such as seating distances in three-dimensional space.

[0249] Figure 8 illustrates a third algorithm, which is a spatial position calculation algorithm related to a method for identifying spatial position information by receiving directional beam projection distance and projection angle data from a directional beam projector and performing calculations using trigonometric functions on these positioning data elements.

[0250] According to the third algorithm, in order for light-emitting devices within the performance venue to identify spatial positional information, the positioning data elements must include "directed beam projection distance and projection angle of the directed beam projector," as shown in Table 2.

[0251] To this end, the positioning data transmission system broadcasts a positioning signal to the directional beam projector, which includes the directional beam projection distance (i.e., the distance between the directional beam projector and the target projection area) and projection angle at the time of directional beam projection, as positioning data elements, to light-emitting devices within the performance venue through the following specific process.

[0252] Step 1.

[0253] The seat map data generator maps the positional information (which may include seat numbers, etc.) of all objects within the performance venue (individual seats, master console, directional beam projector, positioning signal broadcaster, and other objects with defined positions) that are configured according to the venue's layout, to coordinate values ​​in the coordinate system used by the seat map data generator.

[0254] The sheet map generated by the sheet map data generator includes the position information and corresponding coordinate values ​​of all objects within the performance venue. Depending on the case, the sheet map may also include information about the type of coordinate system used in the sheet map (e.g., plane orthogonal coordinate system, spatial orthogonal coordinate system, plane polar coordinate system, spatial polar coordinate system, etc.).

[0255] Figure 8 shows the case where a sheet map is generated using an XY plane orthogonal coordinate system with an X axis (horizontal axis) and a Y axis (vertical axis).

[0256] Step 2.

[0257] The master console reads system data generated by the seat map data generator (which may be an external device or a component integrated into the master console) and spatial position information of all objects within the performance venue into the data management unit.

[0258] Step 3.

[0259] According to the layout of the performance venue, the master console inputs the movement path and movement time of the X-axis or Y-axis of the target projection area of the directional beam projector on the seat map respectively.

[0260] Step 4.

[0261] Corresponding to the position of each object (for example, a seat) belonging to the movement path of the target projection area of the directional beam projector, the master console sets a data sequence including [the distance between the directional beam projector and the target projection area at the directional beam projection time, the projection angle].

[0262] (1) As shown in FIG. 8, the trajectory of the directional infrared beam may move vertically along the Y-axis path or horizontally along the X-axis path under the control of the master console.

[0263] (2) At the same time, the positioning signal broadcaster broadcasts a sequence of positioning signals including [the distance between the directional beam projector and the target projection area at the directional beam projection time, the projection angle] in sequence in synchronization with the movement of the trajectory of the directional beam. The light-emitting devices included in the trajectory of the directional beam detect the directional infrared beam with an IR receiver and the positioning signal with an RF receiver, demodulate the trigger signal and positioning data at the recognized time point, and apply a spatial position calculation algorithm. Therefore, when the beam of the directional beam projector is detected, the distance from the directional beam projector at the projection time of the directional beam projector and the beam projection angle can be identified. The identified positioning data elements are stored in the memory of the light-emitting device.

[0264] FIG. 8 shows a case where a directional beam projector arranged at a point (H) in the performance venue projects a directional infrared beam at a projection angle (θ) to a point (I), and the distance between the point (H) and the point (I) is d_HI.

[0265] The area (HI) covered with a net indicates the target projection area of the directional beam projector.

[0266] For example, the process by which a light-emitting device of a seat located at point (I) identifies its own spatial position information (coordinate values ​​on the XY plane Cartesian coordinate system) according to the third algorithm is as follows:

[0267] Step 1

[0268] (1) The light-emitting device located at point (I) stores in memory the distance (d_HI) between the directional beam projector and the target projection area at the time of directional beam projection, and the projection angle (θ), as described above.

[0269] (2) When point (J) is the intersection of a line drawn perpendicular to the X-axis at point (I) and the X-axis, a triangle (HIJ) is created by connecting points (H), (I), and (J) with an imaginary line, as shown in Figure 8B. In triangle (HIJ), the interior angle of vertex (H) is the projection angle (θ), and the distance between point (H) and point (I) is distance (d_HI).

[0270] In this case, if we define point (H) as the origin, the coordinates of point (H) are (0,0), and therefore the coordinates (x4, y4) of point (I) can be found using equation 7.

[0271] [Equation 7] (x4, y4)=(d_HI·cosθ, d_HI·sinθ).
