| 摘要 |
<p>The invention concerns a method for detecting an object (601) in a zone (603) located proximate to an interface (602) between two liquid (604) and/or gaseous media having different refractive indices, in particular of the air/water type. The method comprises: a step which consists in producing at least a video image of said interface (602) and of said zone (603); a step which consists in producing electric signals (608) representing each video image; a step which consists in digitising the electric signals (608); a step which consists in processing said data by discriminating the data corresponding to the video image of a real object (601) from those corresponding to the apparent video image generated by said interface (602).</p> |
