Of a plurality of learning models learned to output geometric information corresponding to a captured image, a learning model corresponding to a setting region is acquired.

Information processing apparatus, information processing method, and non-transitory computer-readable storage medium

An image processing apparatus that determines a correction parameter for correcting distortion or a position of an image projected on a screen by a projection unit, the apparatus comprises a holding unit which holds a reference pattern constituted by a background region and a plurality of significant pixels scattered in the background region and having a pixel value different from a pixel value of the background region, a generating unit which generates a pattern image to be projected by changing a value of a pixel near the significant pixel in the reference pattern, an acquisition unit which acquires a captured image obtained by an image capturing unit by capturing the pattern image generated by the generating unit so as to include a projection image projected by the projection unit, and a determining unit which determines the correction parameter from the captured image.

Image processing apparatus, control method, and non-transitory computer-readable storage medium

An image processing apparatus for processing an image of a projection content to be projected onto a projection target object including a pattern or a figure in a part thereof, including: a positioning unit configured to perform positioning of the image of the projection content and the projection target object with respect to each other; a transformation unit configured to transform the image of the projection content on the basis of the result of the positioning by the positioning unit; and an output unit configured to output the image transformed by the transformation unit to a projection device.

Image processing apparatus, image processing method, and storage medium

There is provided with an image processing apparatus. A captured image of a target object that is captured by an image capturing apparatus is obtained. Information that indicates a deterioration degree of the captured image is obtained for a position in the captured image. A feature of the target object is extracted from the captured image based on the deterioration degree. The feature of the target object and a feature of the three-dimensional model observed when the three-dimensional model is arranged in accordance with a predetermined position and orientation are associated. A position and orientation of the target object with respect to the image capturing apparatus are derived by correcting the predetermined position and orientation based on a result of association.

Image processing apparatus, image processing method, and non-transitory computer-readable medium

An information processing apparatus comprises a first feature extraction unit configured to extract, as a first feature, a feature of a component assembly in which components are assembled for each of viewpoints; a second feature extraction unit configured to extract a feature of the components as a second feature for each of the viewpoints; and a determination unit configured to determine, based on the first feature and the second feature, a viewpoint for inspecting an assembled state of the components.

Information processing apparatus, method for controlling information  processing apparatus, and storage medium

To perform robust position and orientation measurement even in a situation where noise exist, an image including a target object is obtained, an approximate position and orientation of the target object included in the obtained image are obtained, information related to a shadow region of the target object in the obtained image is estimated, the approximate position and orientation are corrected on the basis of the estimated information related to the shadow region, and a position and orientation of the target object in the image are derived on the basis of the corrected approximate position and orientation and held model information.

Image processing apparatus, image processing method, and storage medium for position and orientation measurement of a measurement target object

There is provided a method for accurately estimating a position and orientation of an object even if the object is more dispersive in shape than a three-dimensional geometric model with a standard shape. The statistic of deviation of a feature constituting a three-dimensional model representing a three-dimensional standard shape of an object is estimated to determine a reliability for each feature. The amount of deviation is calculated between the feature extracted from observation data obtained by an imaging apparatus and the feature in the three-dimensional model. The three-dimensional position and orientation of the object is estimated based on the amount of deviation and the reliability related to each feature extracted from the three-dimensional model.

Position and orientation estimation method and apparatus therefor

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.
