Abstract: Disclosed are a method and an electronic device for determining a homing position of a game gun on a display screen. The method includes: when detecting that a binocular camera accesses, a multicolor filter in the binocular camera is controlled to change colors, the binocular camera is controlled to acquire images of different colors of light spots on a screen of a display screen; identifier information of a plurality of current game guns corresponding to the light spots in the acquired images are determined; and homing positions of the plurality of current game guns on the screen are respectively determined according to the acquired images of the light spots, parameters of the binocular camera, a screen display parameter of the screen and position information between the camera and the plurality of current game guns.

Abstract: Disclosed are a video image processing method and electronic device based on virtual reality. The method comprises: determining a curtain resolution and a monocular rendering resolution in a virtual scene; determining a scaling according to the curtain resolution and the monocular rendering resolution; acquiring a video frame of decoded video data, and scaling the video frame according to the scaling; and transmitting the scaled video frame to a three-dimensional image processor, and carrying out texture mapping according to the scaled video frame and the virtual scene. According to the method, a professional two-dimensional image engine preset in a chip of a chip plant is used for scaling the video frame at first after decoding, and then the scaled video frame is transmitted to a three-dimensional image processor for displaying as a texture, so that the purpose of saving three-dimensional graphic processing resources is achieved.

Abstract: The disclosure provides a method and electronic device for playing subtitles of a 3D video, and a storage medium. The method includes: obtaining subtitles in at least one timestamp of the 3D video; determining whether subtitle contents in the same timestamp among the obtained subtitles are duplicated; if so, then playing the 3D video by playing the subtitle of the 3D video as 3D subtitles; and otherwise, playing the 3D video by processing the subtitles of the 3D video into 3D subtitles, and then playing the 3D subtitles. With the technical solution according to the disclosure, a display effect of the 3D video can be improved.

Each of the knowledgebase models can include a semantic specification and a syntactic specification. The control system can periodically filter non-compliant web services from the web service registry, where a non-compliant web service fails to comply with a predetermined knowledgebase model associated with the web service registry. Other embodiments of the web service management systems, architectures, and methods are also disclosed.

Abstract: In a system for parallelizing polygon overlay operations, a potential for intersection between polygons is determined by the bounding box of each polygon on a base layer in relation to the bounding box of each polygon on an overlay layer. The potential for intersection exists when a vertex of a bounding box around an overlay layer feature is within a bounding box around a base layer feature and vice versa. Calculations to determine the presence of vertices within bounding blocks are performed in parallel on multiple processors. Polygon overlay operations are performed only between features that have a potential to intersect.
