  • Publication number: 20230168745
    Abstract: The present invention provides a gesture recognition apparatus in which a gesture intended to be used for an interface operation is performed at the closest mode of the camera, thus allowing the gesture to achieve interface control. A gesture recognition apparatus according to the present invention includes: an image capturer that sequentially captures distance image data taken by an imaging apparatus; a closest point detector that detects, from the distance image data, a closest point from the imaging apparatus; a gesture measurer that calculates an input switching border for switching ON and OFF of interface input, based on a trajectory of the closest point that is the gesture of the user detected from a plurality of distance image data items; a gesture recognizer that determines whether the input is ON or OFF, in accordance with the input switching border; and an interface controller that performs the interface control associated with the gesture if it is determined that the input has been turned on.

  • Patent number: 8107679
    Abstract: The purpose of the present invention is, in a horse race or a motorboat race, to display the progress of the race (trail) of each horse, by obtaining analysis data of a plural number of patrol images provided around the race course, by acquiring position information of each horse at the moment and by tracking the specific horse through judging similarity between consecutive pictures of said patrol image. The position information analyzing and displaying method for each horse or boat or the like of the present invention, for continuously captured race images, identifies each horse or boat or the like by similarity analysis and tracks continuously the trail of each horse or boat or the like in said racing images, and also analyzes said position information of each horse or boat or the like by using the positional relationship with the fixed position information in said images, in order to display the trail of each horse or boat or the like.

  • Patent number: 7821531
    Abstract: To provide an interface apparatus capable of achieving noncontact and unrestricted arm pointing actions of multiple users in an indoor space, and facilitating the recognition of all typical arm pointing actions in standing, sitting, and lying postures and the operation of indoor units in the indoor space by the arm pointing actions. The interface apparatus includes: image processing means for picking up images of the interior of an indoor space 5 with a plurality of stereo cameras 1-1 to 1-n, and producing a distance image based on the picked-up images within the visual field on a camera-by-camera basis and the coordinate system of the indoor space 5; means for extracting the posture and arm pointing of a user 4 from the distance information from the stereo cameras 1-1 to 1-n; and means for determining, when the arm pointing has been identified, whether the arm pointing is an intended signal, from the direction pointed by the arm and the motion of the arm.

  • Patent number: 7680295
    Abstract: An interface is provided that corresponds to an individual person without being restricted to a particular place within a room, by performing gesture recognition while identifying an individual person. A stereo camera (1) picks up an image of a user (4), and based on the image pickup output, an image processor 2 transmits a color image within a visual field and a distance image to an information integrated recognition device (3). The information integrated recognition device (3) identifies an individual by the face of the user (4), senses the position, and recognizes a significant gesture based on a hand sign of the user (4). The information integrated recognition device (3) executes a command corresponding the identified user (4) and performs operations of all devices (6) to be operated in the room (such as a TV set, an air conditioner, an electric fan, illumination, acoustic condition, and window opening/closing).

  • Patent number: 7460686
    Abstract: The present invention provides a more reliable safety monitoring device on the station platform, where the safety monitoring device detects the fall of a person on the platform edge on the railroad-track side onto a railroad track with stability, recognizes at least two persons, and obtains the entire action log thereof. The present invention recognizes the person at the platform edge by distance information and texture information and determines the position on the platform edge. At the same time, the present invention detects the case where the person falls onto the railroad track with stability and automatically transmits a stop signal or the like. At the same time, the present invention transmits an image of the corresponding camera. Further, the present invention records the entire action of all persons moving on the platform edge.
