Identification et reperage d'objets simples en 
cartographie en temps réel 
Résumé 
Dans le présent exposé, on se penchera sur deux aspects de la 
cartographie en temps réel. D'abord, on traitera de "13 
combinaison des capteurs de collecte de données, comme les 
capteurs de positionnement et d'imagerie utilisés en cartographie 
par ordinateur. Ensuite, on considérera l'élaboration d'une 
méthodologie cartographique, c'est-à-dire de méthodes et 
d'algorithmes d'identification et de repérage d'objets sur 
lesquels des renseignements doivent être captés et stockés dans 
une base de données. Étant donné l'aspect temps réel de ce type 
de cartographie, ces méthodes doivent être simples et fiables. En 
pratique, cependant, il ^en est tout. autrement. Une piece 
d'équipement cartographique permet à son utilisateur d'identifier 
et de repérer des objets dans un cadre de référence absolu. 
Notre exposé portera sur une opération de repérage et 
d'identification des panneaux de signalisation routiére. Nous 
avons élaboré pour cette opération une méthode permettant de 
réduire considérablement le travail du cartographe dans la 
préparation d'une carte des panneaux de signalisation. Cette 
méthode de cartographie automatique comporte plusieurs étapes. On 
segmente d'abord l'image en une zone d'intérêt et une Zone 
d'arrière-plan à l'aide d'un couple stéréoscopique révélant le 
mouvement. On dérive ensuite le champ vectoriel de décalage pour 
cette région. La déconvolution du flou attribuable au mouvement 
produit une meilleure segmentation. On détermine ensuite le 
contour clos de la zone d'intérêt .et..;on.ndérives ses 
caractéristiques affines et invariantes. Enfin, on identifie des 
classes d'objets pour les panneaux de signalisation repérés en 
déterminant.. la: classification. la plus probable a partir de ces 
caractéristiques. Les expériences décrites dans cet exposé ont 
été réalisées en laboratoire et sur le terrain.
