摘要： A method of processing image information is disclosed, for detecting the movement of an object with a simplifed system structure, and high speed treatment. The method is comprised of the steps of entry of a stereoscopic image of an object, extraction of edges of the object, and dividing it into segments based on the local feature of the image. On each segment, tracing points (sampling points) are selected, the inter-frame correlation of selected points is obtained, the three-dimensional coordinates of the points are measured, and thus the position and attitude of the object are detected, wherein the inter-frame correlation is performed by evaluating the similarity between frames based on correlation between the tangential direction of tracing points and the luminance value of the surface.

摘要： An object movement tracking apparatus and its method tracks an object with an unknown initial position and which object is continually moving, the apparatus for recovering a tracking process even when the tracking has failed and includes an observing device such as a video camera for observing a scene at a video frame rate. Time-sequentially acquired image data from the observing device are stored in an image memory device and the data processed in parallel. During data processing, an object recognition module selects a frame memory based on predetermined information. An estimated value of position/posture of the object are calculated from the image data and transmitted. A movement tracking module receives transmitted data from the object recognition module, replacing a current frame with a next frame and waits until image data in the next frame are inputted. When image data inputting is finished, the up dated replacement in position/posture of the object and its evaluated value are calculated by comparing image data and the object model. The system mode is changed and updated based on the obtained evaluated value.

摘要： After stereo image is inputted (S1), the tracing point corresponding to the silhouette of a curved object observed by the stereo image is selected on the basis of the information on the present position of the object (S2), using a three-dimensional geometric model. And the corresponding points on the silhouette corresponding to respective tracing points are sampled from the stereo image (S3), and their three-dimensional coordinates are measured (S4). Then, from the group of the three-dimensional coordinates of tracing points and corresponding points, the position/posture of the object concerned and the measurement error are determined (S5), to discriminate the error (S6). In case the error is not small enough, processes starting from (S2) are repeated, regarding the detected position/posture as a renewed present position, while, if the error is small enough, processes are repeated starting from (S1), regarding the detected position/posture as a renewed present position, thereby providing the technique for high-speed tracing of three-dimensional rigid body motion of an arbitrarily-curved and smooth faced object utilizing an object model, applying a stereo camera system as sensors.
