<p>Method and apparatus for the detection, by means of ultrasonic pulses, of the coordinates of objects with respect to a reference system. The method is based on the transmission of pulses (15) from two senders (2), provided on a testing device (1) at the measuring position, and are received by three sensors (4), arranged with mutual known geometry, and located fixed with respect to the object, for example a car to check. The delays of the pulses transmitted as they are received are measured for determining the position of the two senders (2) and then of a probe (3) to which they are integral. The apparatus allows to detect the distances between points, their symmetries, and, after a calibration step, to determine the position in the space of the measured points, according to a chosen reference system X, Y, Z. The appatus has a software which, by means of a database, allows to compare the measures of the object with the theoretical ones, in order to determine the deformation thereof. The amount of the deformation is indicated both in a numerical and graphical way.</p> |
