Technical Examples
- Embodiments provide geometric consistency in overlapping areas when a tiling projection is performed where adjacent projection images have overlapping areas using a plurality of projectors. Embodiments provide a method in which a geometric correction function is formed on the basis of geometric association between positions, in display areas of projectors PJa to PJd, of features included in pattern images projected from the projectors and positions, in projection areas of the projectors, of features included in pattern-photographed images obtained by photographing the pattern images projected onto a projection plane from the projectors and in which the projection images projected from the plurality of projectors are corrected to have geometric consistency on the projection plane using the geometric correction function. The densities of feature points in specific areas of the display or projection areas of the projectors are set higher than those of areas other than the overlapping areas.
- The method for automatically calibrating a multi-projector system with at least two projectors, a digital camera and a control unit for controlling the projectors and the camera is performed according to the following steps:
- The invention relates to a wash basin (2) for rinsing or washing hair of the head, comprising an illuminating device (3) having a plurality of light projectors (5) for illuminating an inner region (14) of the wash basin (2). Said wash basin (2) consists of a light permeable material (4), the light projectors (5) of the illuminating device (3) being arranged outside the wash basin (2) in such a way that at least one partial region (11) of an outer side (6) of the wash basin (2) can be subjected to light (12).
- A system and method in which one or more acoustic projectors transmit broad bandwidth waveforms having known characteristics, and one or more acoustic receivers detect the transmitted waveforms, with the measurement of a propagation time from the projectors to the receivers being based on knowledge of the transmitted waveforms. The measurements are performed such that there is a low probability that other third party receivers will detect the transmission. The measurements may also be performed in an environment supporting multiple propagation paths. The system and method may further measure the Doppler shift induced by relative motion between the acoustic projector and the acoustic receiver.
- The invention relates to a digital information system (10) for displaying information on at least one display means with the aid of at least one projector (22). The exposures are presented at places accessible to and frequented by a general public. The information system (10) includes external information mediators (24) and information is controlled dynamically through the medium of a communication interface (26) and through the medium of an exposure handler in a central computer (28). The inventive system also include a communication interface (14) against an elective number of station computers (34) having connected projector computers (38) which control projectors (22) for displaying pictures or exposures. The station computers (34) and peripheral equipment are situated at mutually distanced places. According to one particular field of use, the places mentioned are subway stations (16, 18, 20) and projectors (22) project exposures or pictures onto display means positioned at selected places in the stations (16, 18, 20).
