A disclosed display method includes: projecting data of a space that includes a first display provided by a first display device to a perspective view; causing a second display device to display the perspective view on a second display; accepting a designation of a first position on the second display; converting the first position into a second position on the first display, upon detecting that the first position is inside an area that corresponds to the first display; and operating an image displayed on the first display based on the second position.

Display method and display control apparatus

An information processing method including: storing sequential data relating to movements of a target object over a specified plane, sequentially estimating a plurality of first likelihoods of a position of the target object in a direction of the specified plane based on the sequential data, each of the plurality of first likelihoods associating with each hypothesis on the movements of the target object, sequentially estimating a plurality of second likelihoods of touch of the target object on the specified plain based on the sequential data, each of the plurality of second likelihoods corresponding to each of the plurality of first likelihoods, and updating the plurality of first likelihoods based on the plurality of second likelihoods.

Information processing method, information processing apparatus, and storage medium

A content display control method includes displaying a content image on a screen, detecting reflection light of a beam of light reflected off the screen, the beam of light being emitted from a portable device onto the screen, selecting, based on the detected reflection light, a desired one of modes set in association with states of the reflection light changed in accordance with a distance between the screen and the portable device, detecting a user's operation in a period from selecting the mode to turning off the beam of light, based on the state of the reflection light in association with the selected mode, and controlling display of the content image on the screen based on the detected user's operation.

Content display control method and system

A robot of the present invention moves to a place where a user is, in response to the voice of the user who is calling the robot. Then, when the user presses a switch, the robot recognizes that the user desires to send an urgent call and dials a pre-registered telephone number for sending urgent calls. When a receiver responds, the robot reads out and delivers a predetermined message to the receiver as a voice message, and switches the telephone to the handfree state so that the user can talk without holding the telephone.

Robot

A robot system is provided and includes an autonomous mobile robot. In the system in which monitoring is performed using the autonomous mobile robot which travels along a predetermined path, an interval between the time when a user requests transmission of images and the time when the user obtains the images may be reduced. The autonomous mobile robot travels along a predetermined path at predetermined times, a camera takes photographs at predetermined locations during the travel along the predetermined path, images taken by the camera are stored, and the stored images are sent to a requesting cell phone in response to a transmission request from the cell phone.

Robot system and autonomous mobile robot

An image processing process wherein an image is divided into small areas, a polar transformation is applied to the image in each of the small areas, and image processing is performed based on the result of the polar transformation. Further, each of a plurality of images is divided into small areas, a polar transformation is applied to the image in each of the small areas for each of the plurality of images, and correlation is obtained between the results of the polar transformation for the plurality of images. One-dimensional filter processing is applied to the polar-transformed output.

Process and apparatus for extracting and recognizing figure elements

An image processing apparatus is provided which is capable of a high-speed process for obtaining a projection histogram. A digitizing unit subjects a video signal, obtained by acquiring an image of a target mark with a camera, to horizontal scanning and slicing to obtain a binary signal. A window signal output unit, coupled to the digitizing unit, outputs a window signal in accordance with a preset window area. An in-window signal output unit is connected to the outputs of the digital unit and the window signal output unit to perform a logical AND operation on the binary signal and the window signal and outputs an in-window binary signal. A histogram creating unit is coupled to the output of the in-window signal output unit to create a projection histogram by successively counting the high- and low-level states of the in-window binary signal generated as the horizontal scanning progresses. During a horizontal scanning (image scanning) corresponding to one screen, digitization of the video signal, window setting, and generation of the in-window binary signal are carried out, and further a histogram is created based on the in-window binary signal. Namely, scanning the video signal (image) once is sufficient to create a projection histogram.

Image processing apparatus for determining positions of objects based on

A method of extracting a line segment contained in an original image includes the steps of clipping an image, which conforms to the size of a receptive field defining a small area, from the original image, projecting the clipped receptive-field image from a predetermined projection direction onto an axis (.rho. axis) that intersects the projection direction to obtain projection values at positions along the .rho. axis, subjecting the projection values to differentiation processing along the .rho. axis, similarly subjecting projection values, which are obtained by successively varying a projection-direction angle .theta. incrementally a predetermined amount, to differentiation processing along the .rho. axis to thereby obtain a differential value at each position on a .rho.-.theta. plane, and extracting a line segment contained in the receptive-field image based upon a peak position (.rho.,.theta.) of the differential values.

Method and apparatus for extracting line segments from an image of an

An information extraction device including a coordinate transformation unit for transforming the coordinate values of points on a plane in question to the coordinate values of the points on a spherical surface corresponding to the points on the plane, and a mapping unit for mapping the points on the spherical surface to great circles. This information extraction device is applicable to the detection of the three-dimensional direction of a single line or a single plane existing in space.
