Definitions

  • the present invention relates to methods and apparatus for producing panoramic images, and more particularly, to a method and apparatus for tracking an object of interest in such panoramic images and zooming into desired portions of such panoramic images.
  • a number of techniques have been proposed or suggested for capturing the plurality of overlapping images that are used to generate the panoramic image.
  • a number of systems employ multiple cameras to record the multiple images. The multiple images are then processed to create the desired panoramic image. Since the relationship between the various cameras is typically fixed, the relationship between the images is also known. The problem with a multiple camera arrangement, of course, is the additional expense relative to a single camera implementation.
  • a number of systems obtain the plurality of images using a single camera.
  • International Patent Application Number WO 99/62252 discloses a video camera that rotates at a constant speed to capture video images of a panoramic scene of interest. The digital video file can then be processed to create the desired panoramic image.

Abstract

L'invention concerne un procédé et un appareil permettant de suivre un objet présentant un intérêt dans une image numérique présentant au moins une partie à haute résolution. Dans un 'mode de réalisation à miroir profilé', un miroir rotatif profilé agrandit au moins une partie de l'angle de champ de telle sorte qu'une caméra fixe obtient une image à plus haut niveau de résolution correspondant à la région agrandie. Dans un 'mode de réalisation à deux caméras', deux caméras fixes de résolution différente sont focalisées sur un miroir rotatif plat. Une première caméra fixe de moindre résolution produit l'image panoramique d'ensemble et la seconde caméra fixe présentant un plus haut niveau de résolution produit l'image à plus haut niveau de résolution avec un angle de champ plus petit. Dans le mode de réalisation à miroir profilé, un miroir rotatif comprend une région grossissante qui agrandit une partie de l'angle de champ et des régions additionnelles qui réduisent les autres parties de l'angle de champ. Dans ce mode de réalisation, donné comme exemple, le miroir rotatif est bombé pour produire des régions à résolution d'agrandissement variable. Dans le mode de réalisation à deux caméras, donné comme exemple, une image panoramique couvrant 360 degrés est obtenue au moyen d'une première caméra fixe et d'un miroir rotatif plat. Une seconde caméra fixe présentant un plus haut niveau de résolution ou de zoom que la première caméra est également utilisée. Un miroir semi-réfléchissant transmet un pourcentage prédéfini de la lumière réfléchie à la première caméra et réfléchit un pourcentage prédéfini de la lumière réfléchie à la seconde caméra.
