A mobile body spatial information calculation apparatus according to an embodiment includes an input section configured to receive sensor information including information on one or more target objects based on a position of an own mobile body from a sensor apparatus, an object recognition section configured to recognize the target object based on the sensor information, a calculation section configured to calculate a collision prediction time and a target portion angle based on the sensor information on the target object recognized by the object recognition section, and a spatial information generation section configured to generate spatial information according to the collision prediction time and the target portion angle using the collision prediction time and the target portion angle calculated by the calculation section and store the generated spatial information.

Mobile body spatial information calculation apparatus and collision avoidance system

A distance measuring apparatus includes at least one projection unit configured to project a light pattern on a target object, at least one imaging unit configured to capture an image of the target object on which the light pattern is projected, an acquisition unit configured to acquire information about a distance from the projection unit or the imaging unit to the target object based on the image captured by the imaging unit, a grouping unit configured to group surfaces of the target object, and a determination unit configured to determine a light pattern to be projected by the projection unit based on the surfaces grouped by the grouping unit.

Distance measuring apparatus and method

On the basis of captured images at the time of projecting multiple-frequency slit-shaped light patterns having no overlapping edge positions onto an object, the edge portions of the slit-shaped light patterns are identified. When the edge portions overlap in the captured images of two or more slit-shaped light patterns, the reliability of the computed distance values of the positions corresponding to the edges is lowered.

Three-dimensional measurement apparatus, method for three-dimensional measurement, and computer program

A network camera system is provided that detects an occurrence of a condition change at a periphery of an image pickup apparatus, obtains a direction of the detected condition change, and notifies a user of the occurrence of the condition change and a direction of the condition change on a display of a terminal device.

Network camera system and control method therefor in which, when a photo-taking condition changes, a user can readily recognize an area where the condition change is occurring

Subject-distance information is acquired by a light-weight, small-size arrangement without a significant change in the structure of a conventional image processing apparatus. The apparatus acquires diffraction images obtained by sensing the image of a subject, using an image sensing unit, obtained via a diffraction grating and imaging optical system, detects a real image from luminance gradients of the diffraction images, calculates the distance between the detected real image and a virtual image corresponding to this real image in the diffraction images, and calculates the depth distance between the subject and the diffraction grating using the distance calculated by first calculating unit.

Image processing apparatus and method

An imaging apparatus includes a zoom operation unit operable to perform a zoom operation, an extraction unit configured to extract a main object from an captured image plane, and a control unit configured to control a zoom speed by using the size of a region occupied by the main object with respect to the captured image plane and operation information of the zoom operation unit.

Imaging apparatus having enhanced zoom operation

Network camera system and control method therefore

An image distribution method for distributing an image acquired by a camera on a network includes the steps of receiving control information for the camera from an image reception apparatus via a packet-switched network; and sending an image acquired by the camera to the image reception apparatus via a circuit-switched network.

Image distribution method employing both a first network whose bandwidth is not assured and second network whose bandwidth is assured for control and image transmission

A character string is extracted from an image photographed by a camera. It is determined whether or not the extracted character string includes an address on a network. Software for accessing the address runs. Accordingly, a user can easily access a desired address on the network.
