| Abstract(in English) | A new configuration of spatial localized reticles is proposed for applications in real-time object tracking task. While the proposed method is based on spatial filter velocimetry, the motion of a planar object in a three-dimentional environment is decomposed into global affine-motion parameters in the image plane. Global affine-parameters, such as translation, dilation, rotation, and shear can be isolated and identified by measuring the temporal frequency of the reticles arranged on concentric circles in the image plane. Experiments were performed in order to maintain the size and the position of the object's image by controlling the attitude of a camera on the basis of the estimated motion parameters. The proposed system, composed of only a commercially available PC, exhibited good tracking performances with processing rate of 15 frames per second. |
