Abstract: Provided is a system that includes an event-driven vision sensor and an information processing device. The event-driven vision sensor includes a sensor array where a first sensor and a second sensor are arranged in a predetermined pattern. The first sensor generates a first event signal when detecting a change in an intensity of light incident through a first filter. The first filter selectively passes light in a first wavelength band. The second sensor generates a second event signal when detecting a change in an intensity of light incident through a second filter. The second filter selectively passes light in a second wavelength band that is different from the first wavelength band. The information processing device includes a first processing section and a second processing section. The first processing section executes a first process on the basis of the first event signal. The second processing section executes a second process different from the first process on the basis of the second event signal.

Abstract: Provided is a calibration apparatus that performs calibration by using a captured image of a chart including a plurality of plane surfaces forming a predetermined angle θ. An imaging apparatus simultaneously images chart patterns depicted on each of the plane surfaces of the chart. In this instance, the chart pattern depicted on each of the plane surfaces of the chart is inversely projected in accordance with a distance from an imaging plane such that patterns in which feature points are uniformly distributed within the captured image are obtained.

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.

Abstract: Pulsed light emitted from a light emitter of a TOF sensor at an intensity is divided into light that is reflected by an object having transmissivity and reaches a light receiver at an intensity and light that passes through the object and reaches an object at an intensity. The latter is reflected by the object at an intensity, partly passing through the object to reach the light receiver at an intensity. A local maximum point is detected in a change in a degree of photons observed by the light receiver, to acquire both distances to the object and the object.
