An information processing apparatus determines which of a first method for generating virtual viewpoint video upon receiving from an external apparatus object data used for generation of the virtual viewpoint video or a second method for receiving from the external apparatus virtual viewpoint video generated upon a virtual viewpoint designated for generation of the virtual viewpoint video to use as a delivery method for delivery of the virtual viewpoint video; and obtains the virtual viewpoint video by using the determined delivery method.

Information processing apparatus, information processing method, video display system, and storage medium

To prevent an object that should exist in a virtual viewpoint video image from disappearing suddenly. Positional information on a specific object is acquired from a positional information notification unit included in the specific object. Then, based on the positional information, three-dimensional shape data on the specific object is output in association with information specifying a position of the specific object in a three-dimensional space.

Information processing apparatus, control method thereof and storage medium

To prevent an object that should exist in a virtual viewpoint video image from disappearing. The image processing apparatus generates three-dimensional shape data on a moving object from images based on image capturing from a plurality of viewpoints and outputs the data to the apparatus that generates a virtual viewpoint video image. Then, in a case where it is not possible to generate three-dimensional shape data on an object that behaves as the moving object during a part of the period of the image capturing, three-dimensional shape data on the object generated in the past is output to the apparatus that generates a virtual viewpoint video image.

The present invention provides a hall-type electric propulsion that exhibits both overheating protection and operational stability, thereby simultaneously solving the problem of waste heat, which worsens with micronization, and the problem of discharge current oscillation. First, the magnetic flux distribution in ionization/acceleration channel is formed to optimize ion velocity vector, whereupon a propellant flow passage (propellant conduit) is disposed in a magnetic pole of the propulsion, or more specifically in the vicinity of the acceleration channel, and then propellant is passed through the flow passage. Thus, the magnetic pole, which is overheated by the generated plasma, can be cooled, and at the same time the propellant can be heated. Furthermore, the heated propellant is choked immediately before being introduced into the ionization/acceleration channel by a throat region provided immediately before the ionization/acceleration channel, and as a result the sonic speed of neutral species (propellant) is increased.

Hall-type electric propulsion

A pneumatic classifier having a dispersion chamber with crushing function disposed between a material supply port and a classifying chamber so that the material is sufficiently crushed and dispersed before entering the classifying chamber.

Pneumatic classifier

In a classifier having a rotary classifying impeller in a casing for discharging fine powder to the outside of the casing, a leakage prevention apparatus is provided for the classifier which has a rotary seal member mounted on the upper plate of the rotary classifying impeller at the boundary portion between the rotary classifying impeller and a fine powder discharge duct. The upper portion of the rotary seal member protrudes outwardly from an opening in the top plate of the casing to separate the reduced air pressure in the discharge duct perfectly from the high pressure in the raw material dispersion chamber which is radially outside of the seal member. Furthermore, the rotary seal member can be provided with a circular groove in a J-shaped sectional structure. The end portion of this rotary seal member can also be formed into a square shape, a rounded shape or an inclined acute shape.
