摘要： An image processing unit detects a region that corresponds with a subject from a captured image sequence in which a camera and the subject move, based on the three-dimensional shape and motion of the subject. Regions included in captured images are extracted, correspondence is established between the extracted regions, the shape of the corresponding region is estimated by using three-dimensional positions of feature points in the corresponding region, rigid motion of the corresponding region is estimated by calculating motion of each feature point, and region integration or separation is performed based on the estimated rigid motion, whereby the amount of image feature miscorrespondence can be reduced.

摘要： The tunable impedance circuit comprises capacitors C1 and C2, an inductor L1, and an inductor L2 magnetically coupled with the inductor L1. The control current Icontrol with variable phase and amplitude from the control circuit 13 flows in the inductor L2. The impedance of the inductor L1 is changed by changing the phase and amplitude of the control current Icontrol. The output impedance is set to an optimum level by setting an effective inductance and an effective quality factor of the tunable impedance circuit 12a to be optimum by means of the phase and amplitude of the control current Icontrol relative to output current IRF of RF PA 11.

摘要： A color-drift correcting method in an image forming apparatus includes a first and a second color-drift correcting. The first color-drift correcting includes correcting the color-drift amount in a sub scanning direction and a skew relative to the reference color image being based on each color-drift amount of at least three mark-patterns, each of which mark-pattern is formed each color image, so as to decide a corrected-image line as a virtual image line for each color, assumed when the color images are superposed onto a transfer media. A second color-drift correcting includes correcting the color-drift amount in the sub scanning direction so that the virtual image lines corresponding to each of the colors other than the reference color intersect with the virtual image line of the reference color at at least two points.

摘要： Markers are laid out to express a predetermined code string by a plurality of continuous markers. The markers which form a marker string include at least two types of markers having different features which can be identified by image processing. Markers detected in the captured image are converted into numerical information, and are collated based on the numerical information and the predetermined code string. Using information associated with the markers, the coordinate information of each collated marker is calculated. The position and orientation of an image capturing device are calculated using the coordinate information. With a simple arrangement, the position and orientation of an image capturing device can be calculated.

摘要： A measurement apparatus (100), which measures the relative position and orientation of an image-capturing apparatus (50) capturing images of one or more measurement objects (10) with respect to the measurement object, acquires a captured image using the image-capturing apparatus (50). Moreover, the respective geometric features present in a 3D model of the measurement object (10) are projected onto the captured image based on the position and orientation of the image-capturing apparatus (50), thereby obtaining projection geometric features. Projection geometric features to be used in calculation of the position and orientation are then selected from the resultant projection geometric features based on distances between the projection geometric features in the captured image. The relative position and orientation of the image-capturing apparatus (50) with respect to the measurement object is then calculated using the selected projection geometric features and image geometric features corresponding to the selected projection geometric features detected in the captured image.

摘要： A measurement line segment projection unit (400) projects, onto a sensed image, a three-dimensional model which is arranged at the position and orientation of a physical object (199). A search range is set for each side of the virtual object projected onto the sensed image, near the side of the virtual object in the sensed image based on a positional relationship between the side and other sides of the virtual object. A side of the physical object (199) on the sensed image is searched for within the search range for each side of the virtual object. The position and orientation relationship between the physical object (199) and an image sensing device (50) is calculated using the correspondence relationship, determined based on the search result, between each side of the three-dimensional model projected onto the sensed image and each side of the physical object (199) located on the sensed image.
