| 20080240550 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - By applying identification processing to each index included in a captured image, a set of an identifier, image coordinates, and an image number is acquired for each index, and the acquired set is registered in a data saving unit. The data saving unit manages the numbers of times of previous identification for respective identifiers. A display unit displays the number of times managed in association with an identifier in a set to be registered every time the set is registered. An index position and orientation calculation unit calculates the positions and orientations of indices corresponding to a set group using the set group registered in a memory. | 10-02-2008 |
| 20080285854 | MARKER ARRANGEMENT INFORMATION MEASURING APPARATUS AND METHOD - A marker arrangement information measuring apparatus includes an image acquiring unit configured to acquire a captured image, a marker detecting unit configured to detect markers from the captured image, a marker identifying unit configured to identify the marker detected by the marker detecting unit, an arrangement information calculating unit configured to calculate arrangement information of the marker based on an identification result of the marker identifying unit, an analyzing unit configured to analyze the identification result of the marker identifying unit, and a display unit configured to display an image corresponding to an analysis result of the analyzing unit on the captured image in a combined manner, thus presenting the analysis result to a user. | 11-20-2008 |
| 20080291219 | Mixed reality presentation apparatus and control method thereof, and computer program - Position and orientation information indicating the relative position and orientation relationship between the viewpoint of the observer and a physical space object on a physical space is acquired. A virtual space image is generated based on the acquired position and orientation information, and is rendered on a memory. A physical space image of the physical space object is acquired. By rendering the acquired physical space image on the memory on which the virtual space image has already been rendered, the physical space image and the virtual space image are combined. The obtained composite image is output. | 11-27-2008 |
| 20090022369 | POSITION/ORIENTATION MEASUREMENT METHOD AND APPARATUS - This invention relates to a position/orientation measurement apparatus which can measure a position and orientation while achieving both high stability and precision. An image including indices laid out on a space is captured, and the indices are detected from the captured image. When a plurality of indices are detected, their distribution range is calculated, and an algorithm to be applied in position/orientation calculations is selected according to the size of the range (S | 01-22-2009 |
| 20100226550 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - This invention is directed to appropriately searching for case data similar in the process of a disease. A similar case search apparatus ( | 09-09-2010 |
| 20100277572 | INFORMATION PROCESSING APPARATUS AND CONTROL METHOD THEREOF - A technique for reducing the time required before a tracking process is performed again in calculating the position and orientation of an image capturing apparatus or an object. Images captured by the apparatus are acquired, the acquired images are stored in order per frame, straight lines detected in the captured images and straight lines in a three-dimensional space model are matched, the position and orientation of the apparatus are initialized by obtaining correspondences having the highest consistency, a captured image to be processed is selected from the captured images, the change in position and orientation of the apparatus is measured using the change in position and orientation of a target object in the selected image based on the initialized position and orientation of the apparatus, and if the measured change in position and orientation is not within a predetermined threshold, initialization is performed using the selected image. | 11-04-2010 |
| 20100295924 | INFORMATION PROCESSING APPARATUS AND CALIBRATION PROCESSING METHOD - An information processing apparatus, which provides images for stereoscopic viewing by synthesizing images obtained by capturing an image of real space by a main image sensing device and sub image sensing device to a virtual image, measures the position and orientation of the main image sensing device, calculates the position and orientation of the sub image sensing device based on inter-image capturing device position and orientation held in a holding unit and the measured position and orientation of the main image sensing device. Then the information processing apparatus calculates an error using the measured position and orientation of the main image sensing device, the calculated position and orientation of the sub image sensing device, and held intrinsic parameters of the main image sensing device and sub image sensing device. The information processing apparatus calibrates the held information based on the calculated error. | 11-25-2010 |
| 20110131158 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - An information processing apparatus that selects a plurality of feature amounts acquired by applying a filter to learning data and generates a discriminator based on the selected feature amounts includes a time specification unit configured to specify a calculation time required for acquiring a feature amount of a selection candidate by applying the filter to the selected feature amounts or the learning data, a precision specification unit configured to specify a precision of a discriminator generated based on the feature amount of the selection candidate and the selected feature amounts, a selection unit configured to select the feature amount of the selection candidate based on the calculation time and the precision, and a generation unit configured to generate the discriminator based on the selected feature amounts. | 06-02-2011 |
