An photometric sampling apparatus for an object surface shape and reflectance extraction system includes an array of point light sources spaced apart from one another in an arcuate configuration about a common site at which an object is placed from inspection, an array of extended light sources spaced apart from one another in an arcuate configuration about and oriented in different directions toward the common site, and a viewing device for viewing the object from a single direction when placed at the common site in order to extract information corresponding to the image of the object viewed. The array of point light sources can be activated for emitting light therefrom along different orientation angles toward the object at the common site. The array of extended light sources are generated on the surface of a light-diffusing medium, such as a translucent globe, disposed between the array of point light sources and common site. Each extended source emits light from an area of points unlike each point source which emits light from a single point. A scanner device is connected to the point light sources for sequentially activating them to emit light therefrom. In response to the sequence of emitted light, the extended light sources are generated in a scanning fashion for producing a sequence of images of the object at the viewing device.

A Mixed Reality display system and others capable of experiencing Mixed Reality by changing own line of sight of a user in a case where a plurality of users experience a synthesized image are provided. The Mixed Reality display system is a system in which an image providing server and a plurality of client terminals are constructed to be capable of being communicated with each other, the image providing server represents a virtual object, synthesizes the represented object and an omnidirectional image taken by an omnidirectional image obtaining camera, and then delivers the synthesized image information to a plurality of client terminals. The client terminal extracts a partial area image from the synthesized image indicated by the synthesized image information received from the image providing server based on the portion/pose information defining the line of sight of a user observing the client terminal, and then displayed the extracted image.

A system and process for efficiently representing an object and allowing the synthesizing of photo-realistic images of the object that depict both diffuse and specular reflections therefrom. This is accomplished using a sparse set of input images and a geometric model of the object. In particular, the reflectance components (i.e., diffuse and specular) are separated out of the input images based on the intensity variation of object surface points. The diffuse reflection component is characterized with a global texture map, while the specular reflection components are used to model the illumination distribution of the environment surrounding the object and to estimate the surface reflectance parameters. This framework provides a very compact representation of the object's appearance. Photo-realistic virtual images of the object from any desired viewpoint can be synthesized using the previously computed global texture map, illumination distribution, and reflectance parameters.

A feature amount of an inter-mobile unit relative movement are detected as an observation amount by an observation amount detecting section 26, time series of the observation amounts are stored as an observation series into a storage section 27 to calculate a similarity of the observation series to a predetermined collision observation series by a classification section 28. A determination section 29 determines to be a collision accident if, in a case where the similarity is larger than a predetermined value, a mobile unit associated with the similarity is at rest in a stoppage prohibition area set in a storage section 30 and another mobile unit is moving, and to be a mobile unit failure if collision determination conditions except for the similarity are met. By consisting of not only a first scalar obtained by quantizing a relative velocity vector between mobile units but also a second scalar obtained by quantizing a relative position vector between mobile units as the observation amount, a relative movement between mobile units is classified in more detail. A mobile unit is tracked in units of block by a mobile unit tracking section 25 to discriminate overlapped mobile units in pictures.
摘要:
By narrow region communication between a gate side communication apparatus (G-COM) and a mobile unit side communication apparatus (M-COM) passing through an on-road real gate at an interconnection, the G-COM assigns a real identification code (R-ID) ID1 including an intersection number to the M-COM after receiving a R-ID ID0 having been assigned from the M-COM, while time series pictures of the intersection including all real gates are taken by a camera 15 installed to assign a virtual identification code (V-ID) to a mobile unit passing through a slit, corresponding to a real gate, in pictures by processing them. In response to the assignment of the R-ID, the R-ID is brought into correspondence with the V-ID. The mobile unit is tracked and when an anomalous behavior thereof is detected in pictures, warning information is transmitted to the M-COM using the corresponding R-ID. By gathering sets of ID0 and ID1 associated with each other in a plurality of intersections, a mobile unit having displayed an anomalous behavior is tracked.

A registration processing apparatus generates a polynomial to calculate a value corresponding to a distance from the surface of a target object in a first image, and acquires a plurality of position coordinates on the surface of the target object in a second image. Then the apparatus respectively calculates a value corresponding to the distance from the surface of the target object in the first image using the polynomial, for position coordinates obtained by coordinate conversion of the plurality of position coordinates. The apparatus coordinate-converts the position coordinates of the second image by a coordinate conversion method for the plurality of position coordinates determined based on the calculated values.
