A motion sensor device including: an image sensor; first and second light sources; and a controller configured to control the image sensor and the first and second light sources. The controller makes the image sensor capture a first frame with light emitted from the first light source at a first time, makes the image sensor capture a second frame with light emitted from the second light source at a second time, performs masking processing on a first image gotten by capturing the first frame and on a second image gotten by capturing the second frame based on a difference between the first and second images, and obtain information about the distance to an object shot in the first and second images based on the first and second images that have been subjected to the masking processing.

Examples described herein provide a method for performing a predictive collision analysis. The method includes initiating, on a processing system, the predictive collision analysis to be performed on the processing system. The further method includes defining a virtual mirror property for a virtual mirror for the predictive collision analysis. The method further includes performing, by the processing system, the predictive collision analysis. Performing the predictive collision analysis includes generating a virtual mirror graphical representation including the virtual mirror based on the virtual mirror property.

The present invention relates to a virtual sport system for acquiring a good image of a ball by controlling a camera according to the surrounding brightness. One embodiment of the present invention provides a virtual sport system which comprises a photographing unit, having a camera for acquiring an image of a ball, and a simulator, for calculating the physical quantity of the ball on the basis of the image of the ball; and which further comprises a control unit that extracts image information from at least one image acquired by the photographing unit by means of the camera, and determining, on the basis of the image information, a control signal for adjusting the image gain or the exposure time of the camera.

The present invention relates to a system and method for photographing a moving subject by means of a camera, and acquiring the actual movement trajectory of the subject on the basis of the photographed image. One embodiment of the present invention provides a method for acquiring the movement trajectory of a subject, the method comprising: a step for photographing a moving subject by means of a camera; a step for collecting, from the camera, information on multiple images of the subject and the positions of the images on a camera image frame, and collecting information on the size of the images; and a step for acquiring the movement trajectory of the subject on the basis of the information collected.

A system for performing 3D scanning of an object using multiple projectors projecting a grid of source light signals on surface points of the object, with at least two of the projectors projecting overlapping source light signals; multiple cameras capturing images defining a grid of corresponding light intensities on the outer surface of the object varying over time to define a received light signal for each surface point; and a computing device controlling each one of the projectors such that each source signal of the grid of source light signals projected therefrom has a unique signal characteristics allowing a subsequent demultiplexing of received light signals for surface points where the source light signals of at least two overlapping projectors are combined, and perform signal processing on each received light signal to isolate therefrom constituent source light signals having the unique signal characteristic associated to a corresponding one of the projectors
