Abstract
An installation for separating and singulating non-uniform postal articles of the small parcel or packet type is characterized in that it comprises a platform for storing a pile of loosely placed postal articles, a vision system adapted to form digital images of the pile of loose postal articles, which pile is static on the platform, and a pneumatic pickup head of a robotized arm. The vision system comprises at least one laser source that projects a beam of fanned-out laser lines onto the pile of articles, thereby making it possible, on the basis of images including the laser lines on the pile of articles, to compute accurately a map of depths, and to perform digital silhouetting so as to singulate an article from the pile of loose articles.
