The present invention relates to a device (4) and method for producing data concerning one or more properties of an environment, the device (4) comprising: a transducer (6) mechanically connected to a sensor (5), a relative position and orientation of the sensor and the transducer being fixed with respect to each other, said transducer being arranged to receive signals from signal sources in the environment. Said transducer is configured to determine a direction (Õ 1 , ˜ 1 ; Õ 2 , ˜ 2 ; Õ3, ˜ 3 ) of a sightline extending between the transducer and each of at least three of the signal sources with each determined direction measurement comprising two angular measures (Õ i , ˜ i ) measured relative to the transducer, and calculating the position and orientation of the transducers. The sensor (5) is configured to measure a property of the environment at, at least one position or along a line correspondingly. The device further comprises: means for calculating the sensor's position and orientation relative to the environment, the sensor's position and orientation being calculated with at least four degrees of freedom and means for generating at least three sets of data, and using i one or several of degrees of freedom of the calculated position and orientation of the sensor and ii the measured property of the environment from at least three sets of data to produce a model of the environment, said model being one of for zero (0) to two (2) spatial dimension sensors, the device emits said measured environmental information in at least one additional spatial dimension than the number of spatial dimensions output from the sensor, or a 3D model of the environment viewable from plural perspectives. |
