摘要： Generation of an inappropriate image portion in an orthographic image due to occlusion is prevented. An image processing device includes an image data receiving part that receives image data of multiple photographed images taken by photographing an object from different positions, a coordinate designating part that receives designation of a specific position in the object, and an optimum-condition satisfying image selecting part that selects a photographed image that is taken from a direction in a specific range relative to the specific position, from among the multiple photographed images. The selected photographed image is used to obtain pixel information of the specific position.

摘要： Embodiments of the present invention disclose a depth information obtaining method and apparatus, and an image acquisition device. The image acquisition device includes a first camera and a second camera. When detecting that shaking occurs, the depth information obtaining apparatus may obtain images captured by the first camera and the second camera, detect an initial distance between a target shooting object in the two images, correct the initial distance by using an offset difference between a first image and a second image, and determine a depth of the target shooting object by using the corrected initial distance. In the embodiments of the present invention, the two cameras may both have an OIS function, or either of the cameras has an OIS function. When performing OIS, the depth information obtaining apparatus corrects the distance between the same shooting object in the images obtained by the two cameras, so that finally obtained depth information is relatively accurate. This can accurately and quickly implement focusing on the shooting object.

摘要： A method of calculating a most likely map based on batch data includes gathering a corpus of sensor measurements indexed by a location of a sensor throughout an environment to be mapped. The method also includes determining, after gathering the corpus of sensor measurements, a most likely occupancy level of each voxel of multiple voxels of the environment in accordance with the corpus of sensor measurements and a stochastic sensor model. The method further includes calculating the most likely map based on the determined most likely occupancy level.

摘要： According to an embodiment, a pose estimation apparatus includes first and second imagers and an estimator. The first imager generates first and second standard images respectively captured at first and second times. The second imager generates first and second reference images respectively associated with the first and second times. The estimator estimates, based on the first and second standard images and the first and second reference images, (a) a pose of the first imager at the first time, with a pose of the first imager at the second time being regarded as a standard and (b) a positional shift of the second imager capturing the first reference image from an estimated position of the second imager at the first time.

摘要： A 3D imaging system is proposed in which an object is successively illuminated in at least three directions and at least three images of the object are captured by one or more energy sensors. A set of images is produced computationally showing the object from multiple viewpoints, and illuminated in the at least three directions simultaneously. This set of images is used stereoscopically to form an initial 3D model of the object. Variations in the brightness of the object provides features useful in the stereoscopy. The initial model is refined using photometric data obtained from images in which the object is illuminated in the at least three directions successively.

摘要： An image acquisition block 42 of an information processing apparatus 10 acquires stereo images taken by a first camera 13a and a second camera 13b that make up an imaging apparatus 12. An input information acquisition block 44 accepts a user manipulation. A first positional information acquisition block 52 of a positional information generation block 46 identifies an approximate position of an object to be imaged through predetermined means. A second positional information acquisition block 56 determines an estimated distance range of a target on the basis of the identified approximate position of the object to be imaged, detects corresponding points by executing block matching on stereo images thorough only a search range corresponding to the determined estimated distance range, and obtains a position of the target with high resolution and accuracy. An output information generation block 50 generates output data on the basis of the position of that target and outputs the generated output data.
