Method for determining the movements of an object from a stream of images

摘要

According to one aspect, the invention relates to a system for determining the movements of an object from a stream of images of said object. The system includes, in particular, a computer having a memory and a central processing unit, said central processing unit including: a reading unit (12) for recording each image of the stream of images in an input buffer memory (22); a processing unit (13) making it possible to determine, for each image, a change in the position and/or in the deformation of said object relative to the image immediately preceding said image in the stream; the reading and processing units being synchronized such that the processing of each of said images of the stream of images is carried out either simultaneously at the time of the reading of an image following said image in the stream of images, and of the recording thereof in the input buffer memory (22).

主权项

1. A method carried out by a computer for determining movements of an object from a stream of images of said object, comprising for each image of the stream of images:
recording said image in an input buffer memory; processing said image by a processing unit, the processing comprising the determination of a change in position and/or deformation of said object relative to an image directly preceding said image in the stream; and synchronizing the recording and processing steps in such a way that the processing of an image is carried out simultaneously with the recording of an image following said image in the stream of images, wherein the synchronizing step comprises:
transmitting to a control unit information relating to the recording of an image in the input buffer memory and to an end of processing of an image; andtransmitting by said control unit instructions relating to a start of processing of an image, a processing start instruction being transmitted to start the processing of an image following the reception of the information relating to the recording of said image and the reception of the information relating to an end of processing of the image directly preceding said image in the stream of images.
