(FR) PROCÉDÉ ET SYSTÈME DE TRAITEMENT D'IMAGE
Abstract: front page image
(EN) A method and a system for processing images are disclosed herein. The method includes: obtaining video images or capturing a series of images in real time; detecting difference between two adjacent images, and reserving one of the images when the difference is less than a preset threshold; detecting feature information of the obtained images; and performing definition-related treatment for the images detected as having the feature information, comparing definition of each image with a preset definition criterion, and reserving clear images. In the prior art, the camera calibration method cannot select a proper clear image automatically, and involves participation of multiple persons, thus bringing much inconvenience. The embodiments of the present invention overcome such problems, select the images which have distinct feature information, and are suitable for calibration among the video images automatically in real time, thus automating steps of image processing.
(FR) L'invention porte sur un procédé et système de traitement d'image, le procédé comprenant : l'acquisition d'une image vidéo ou l'acquisition d'une série d'images isolées en temps réel; la vérification de la différence entre les deux images précoces ou tardives, lorsque la différence entre les deux images est inférieure à la valeur de seuil réglée au préalable, la sauvegarde d'une image isolée dans celles-ci; la vérification des informations caractéristiques de l'image isolée acquise, le traitement de l'image isolée qui a les informations caractéristiques après la vérification correspondant à la définition, et la comparaison à la norme de définition réglée au préalable, la sauvegarde d'une image claire.
