    摘要: The invention relates to a detection system for determining data embedded into the light output of a light source in a form of a repeating sequence of N symbols. The detection system includes a camera and a processing unit. The camera is configured to acquire a series of images of the scene via specific open/closure patterns of the shutter. The processing unit is configured to process the acquired series of images to determine the repeating sequence of N symbols. By carefully triggering when a shutter of the camera is open to capture the different symbols of the encoded light within each frame time of a camera, a conventional camera with a relatively long frame time may be employed. Therefore, the techniques presented herein are suitable for detecting the invisible “high frequency” coded light while using less expensive cameras as those used in the prior art.

    摘要: Coded light has been proposed to enable advanced control of light sources and transmit information using light sources. It is based on invisibly embedding of data and identifiers in their light output. Methods, devices and systems configured to efficient assignment of addresses in a coded lighting system, still allowing for unique identification, are proposed. More specifically, the assignment of addresses occurs in two phases, where in the initial phase wide area unique addresses are used, while in the second phase only local area unique addresses are used. Also, methods, devices and systems configured to efficiently distribute a set of addresses over a set of light sources in this second phase, to maximize the performance of the illumination contribution estimation, and positioning, are disclosed.

    摘要: The present invention relates to light-based communication, and more particularly it relates to methods for configuration of at least one remote light-sensing device, to a central light-emitting unit and to a light-sensing device. According to the invention, spatial configuration of remote light-sensing devices (e.g. peripherals such as loudspeakers or light devices), will be achieved by transmission of embedded identifiers or configuration information in light emitted in a plurality of directions from a central light-emitting unit. With a different identifier or different configuration information for each direction of transmission, the directions can be distinguished from each other. The invention enables a user to place remote light-sensing devices in a desired spatial position and the central light-emitting unit will be able to determine location and spatial function, i.e. for example whether the peripheral is an audio device and/or a lighting device. As a result, the peripherals will be correctly configured without any user interaction required.

    摘要: There is provided a method for advanced configuration and initialization of a luminaire system. The luminaire system comprises one or more lighting devices (102), an apparatus (104) and a user interface (106). The apparatus comprises a light sensor. One or more of the lighting devices are not connected to a central controller by means of a wired/wireless connection. Therefore, techniques and procedures to use manual interaction by an operator (114) to control these lighting devices are proposed. The proposed techniques enable backward compatible and low-cost implementations of advanced luminaire initialization and configuration. Moreover, this invention proposes to combine the user input, sensing and control functionality into one device, thereby reducing the total cost of implementation and ownership of the proposed system. A corresponding system and apparatus are also presented.

    摘要: The invention relates to a detection system for determining whether a light contribution of a light source is present at a selected position within a 2D scene. The light contribution includes an embedded code comprising a repeating sequence of N symbols. The detection system includes a camera and a processing unit. The camera is configured to acquire a series of images of the scene via specific open/closure patterns of the shutter. Each image includes a plurality of pixels, each pixel representing an intensity of the light output of the light source at a different physical position within the scene. The processing unit is configured to process the acquired series of images to determine whether the light contribution of the first light source is present at the selected physical position within the scene by e.g. correlating a sequence of pixels of the acquired series corresponding to the selected physical position with the first sequence of N symbols.

    摘要: Commissioning a coded light source in a lighting system is accomplished by using a remote controller. When an identification of a light source is successful, a control message is sent to that light source to at least partly switch off its light emission. Thus the light contribution of the identified light source is suppressed. Thereby the chance of coded light from an already identified light source colliding with identifiers comprised in coded light emitted by other light sources is reduced. When no more coded light is detectable, a sensitivity of the remote controller can be increased until coded light again is detectable. Further light sources can then be identified and commissioned.

    摘要: A vehicle position measurement system (100) and method to determine the (relative) position of a vehicle (110) and an object (120) are proposed. The system comprises at least two light sources (131, 132) capable of emitting light and positioned at a predetermined distance (140) to each other. Furthermore the system comprises at least one detector (150/151, 152) capable of measuring the light emitted. The light emitted by the light sources comprises synchronized light source identification codes. The detector is arranged to determine the position of the vehicle (110) and object (120) on the basis of a phase-difference measurement between the light originating from the individual light sources (131, 132) and a comparison phase. The vehicle (110) may comprise the at least two light sources (131, 132) and the detector (151, 152), while the phase-difference is measured between light reflected from the object (120) and the comparison phase. Alternatively, the vehicle (110) may comprise the at least two light sources (131, 132) while the object (120) comprises the detector (150) and the detector is arranged to obtain the comparison phase from the light received from one of the light sources (131, 132). The object may be a vehicle.
