Abstract: An information processing device causes an information processing section to perform information processing of a game for example, based on a user's operation received by an input information acquiring section and on images acquired by a stereo camera and obtained through an acquired image obtaining section. The information processing device causes an output data generating section to output the result of the information processing to a display device. At this point, a tracking processing section detects corresponding marker images from stereoscopic images and, based on a parallax therebetween, obtains position information about a target object. In accordance with vertical position misalignment between the detected marker images, a calibration determining section determines whether camera calibration is needed and requests the output data generating section to notify the user of the determined need.

Abstract: As a user guide, the state of overlooking a real space including an imaging device and a user is presented by one of two images: an image in reference to the position of the imaging device, or an image in reference to the user's direction. In both images, a rectangle indicative of the imaging device and a circle representative of the user are presented in a manner reflecting the actual positional relations and directions involved. Also presented are an area denoting a play area in the horizontal direction determined by a camera angle of view for example, and an arrow pointing to the direction in which the user is to move.

Abstract: A detection area is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area, coordinate points (white and black dots) represented by pixels making up a silhouette of the hand in a depth image enter the detection area. In the detection area, a reference vector is set that shows the direction which the hand should face relative to the shoulder as a reference point. Then, an inner product between two vectors, a vector from the reference point to each of coordinate points and the reference vector, is calculated, followed by comparison between the inner products. Positions of coordinate points whose inner products are ranked high are acquired as the position of tips of the hand.

Abstract: [Object] To perform more stable and highly accurate attitude estimation.[Solution] The attitude optimization unit optimizes the articulation position, the angle, the number of articulations, and the like which are attitude parameters of a human body model (tree structure) by a plurality of optimization techniques so as to match a region in which a human body can exist, and switches among a plurality of optimization techniques and uses an optimum technique. Note that optimization techniques include 1. initial value, 2. algorithm, and 3, restriction, and optimization is performed by switching among these three. For example, it is possible to apply the present disclosure to an image processing device that performs image processing of optimizing the articulation position and angle of a human body model.

Abstract: An image acquisition block of an information processing apparatus acquires stereo images taken by a first camera and a second camera that make up an imaging apparatus. An input information acquisition block accepts a user manipulation. A first positional information acquisition block of a positional information generation block identifies an approximate position of an object to be imaged through predetermined means. A second positional information acquisition block 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 generates output data on the basis of the position of that target and outputs the generated output data.
