Abstract

Industrial automation, robotics and automatic inspections include the processing of image sequences. Especially the registration of dynamic process parameters such as velocity and acceleration is realized with real time image processing. In this paper a visual motion detection system is used for contactless measurement of dynamic process parameters in a continuous rolling process. The motion of hot tubes is detected during an image sequence analysis by observing the translation of specific templates that are extracted from the texture of the tubes' surfaces. The texture is necessary for faultless operation of the system. Actually there are some tubes without a clearly visible texture. The paper presents methods for preprocessing the image's data in order to model pseudo texture. The motion is analyzed by using correlation procedures in several areas of interest in an image. The paper describes the problems of an on- line motion detection in an image sequence and offers theoretical and practical approaches to solve them.
