Abstract: L'invention concerne un procédé de montage de module de caméra et une plate-forme mobile utilisés pour la conduite automatique ou la conduite intelligente. Le procédé de montage de module de caméra suppose de monter un module de caméra sur la plate-forme mobile. Le module de caméra est parallèle au sol sur lequel la plate-forme mobile est située. Le module de caméra comprend un groupe de lentilles et un capteur d'image. Le groupe de lentilles contient au moins une lentille. La projection du centre du groupe de lentilles sur le plan du capteur d'image est une première position. La distance entre la première position et le centre du capteur d'image est supérieure à un premier seuil. Le premier seuil est supérieur à 0. De cette manière, puisque le module de caméra peut être parallèle au sol sur lequel la plate-forme mobile est située, il est possible de s'assurer que la direction de mouvement est perpendiculaire au plan du capteur d'image. Par conséquent, la précision et la robustesse de l'estimation du mouvement de la caméra peuvent être améliorées, les erreurs de positionnement cible sont réduites et la plage de détection requise peut être satisfaite sans monter obliquement le module de caméra.  Le procédé peut être appliqué à l'Internet des véhicules, telles les communications de véhicule à tout (V2X), Long Term Evolution-véhicule (LTE-V) et de véhicule à véhicule (V2V).
