Abstract
The present invention relates to a device () for inspecting objects () moving in a flow (F) on a surface () moving in a direction (D), this device () comprising a lighting means () providing an illuminated strip () at the surface (), a detection means () having an optical axis (AO) and, finally, a means () for processing and evaluating the signals supplied by the detection means () in order to detect the presence of the moving objects (), map their height and/or determine their volume. This device () is characterised in that the median plane (PM) of the light beam () and the optical axis (AO) of the detection means () have an angle (AP) between them, in that the image of the illuminated strip () acquired by the detection means () has a width equal to at least three times the resolution of the means (), and in that the lighting means () is configured in such a way that the illuminated strip () generated at the support surface () is delimited by two opposing straight parallel edges and has a sufficient contrast with respect to the non-illuminated zones (), regardless of the colour of the object ().
