DEVICE AND METHOD FOR LOCATING IMPACTS ON THE OUTER SURFACE OF A BODY

摘要

A method and device to locate an impact on an outer surface of a body including: locating the impact on the outer surface of a virtual model of the body; selecting a first and a second visual reference element on the virtual model; positioning an acquisition module on the outer surface of the actual body at the impact; measuring, using an acquisition module, measuring distances between the impact and the first visual reference element and between the impact and the second visual reference element; calculating a first arc around the first visual reference element and a second contour around the second visual reference element wherein each arc has a radius equal to one of the measured distances; determining a point of intersection of the first and second contours; and calculating coordinates of the point of intersection on the virtual model to locate the impact on the virtual body.

1. A method for locating an impact on an outer surface of a body comprising:
accessing a virtual model of the body stored in a database; locating, via a man-machine interface, the impact on the outer surface of the virtual model of the body displayed on a display screen; selecting a first and a second visual reference element on the virtual model of the body; positioning an acquisition module on the outer surface of the body at the impact; measuring, using an acquisition module, a first curvilinear distance between the impact and the first visual reference element on the body and a second curvilinear distance between the impact and the second visual reference element on the body; calculating, by a central processing unit and as a function of the first and second distances, a first contour around the first visual reference element on the virtual model and a second contour around the second visual reference element; determining, by the central processing unit, a point of intersection of the first and second contours; calculating, by the central processing unit, coordinates of said point of intersection on the virtual model of the body, and the coordinates of said point as being representative of the coordinates of the impact, and generating by the central processing unit a presentation presenting the coordinates of the impact.
