| 摘要 |
The invention relates to a sensory system which is based on ultrasonic trilateration measurements and which can be used to measure the position of an object in the three Cartesian co-ordinates thereof, X, Y and Z, with millimetric precision, in external environments with air currents, even when the object to be located is not visible in relation to the static markers required in order to apply the principle of trilateration. In addition, the inventive device can be used to obtain the profile or contour of the object, which can in turn be used to characterise said object in terms of shape and orientation in relation to the major axis of symmetry thereof. The device is designed and intended to be used to determine the position co-ordinates, the shape and the orientation of objects found during the excavation of paleo-archaeological sites, although it is also suitable for use in other sectors.
