| description | The video-laser detection device comprises means of transporting in a predetermined direction the part to be analysed, at least one laser source for directing towards the part to be analysed a light beam in a lighting plane whose intersection with the base plane of the object is perpendicular to the said predetermined direction, and at least one matrix video camera whose field corresponds to the said lighting plane and whose scanning lines are perpendicular to the said intersection. So as to accurately determine in real time the profile of the part, means of processing the video signal emitted by the video camera when the part to be analysed is illuminated via a laser lighting plane comprise a circuit (20) for extracting line and frame synchronising signals, an analog/digital convertor (30), a device for extracting the point of maximum luminance per line and computational circuits for determining the characteristics of the part to be analysed from the coordinates of the points of maximum luminance of each of the video signal lines. |
