Augmented reality virtual guide system

A computer-implemented method for providing an augmented reality interface, comprising:npreloading a plurality of image snippets from a server based on a location information of a portable electronic device, each of the plurality of image snippets being a smaller image file of a corresponding stored image;acquiring an image of a real-world scene and metadata with a camera of a portable electronic device;overlaying one or more of the plurality of image snippets corresponding to a location and a direction at which the image was originally captured based on the location information and a orientation information of the portable electronic device without manipulating the plurality of image snippets based on corner features of the image of the real-world scene;manipulating a retrieved image corresponding to an displayed image snippet based on matching corner feature information of the displayed image snippet generated and provided by the server and corner features of the image of the real-world scene, wherein the retrieved image is retrieved with metadata having selected features;combining the manipulated retrieved image with a currently observed real-world scene viewed with the portable electronic device; andproviding guide information related to the selected features;wherein manipulating the retrieved image comprises applying a transformation matrix to a plurality of nested views of the retrieved image, wherein the transformation matrix approximates a perspective distortion caused by a movement of the camera.

A system for providing an augmented reality interface, comprising:na processor; anda memory containing instructions that, when executed by the processor cause the processor to:preload a plurality of video snippets from a server based on a location of a location information of a portable electronic device, each of the plurality of video snippets being a smaller video file of a corresponding stored video;acquire a video of a real-world scene and metadata with a camera of a portable electronic device;overlay one or more of the plurality of video snippets corresponding to a location and a direction at which a corresponding video was originally captured based on the location information and a orientation information of the portable electronic device without manipulating the plurality of video snippets based on corner features of the video of the real-world scene;manipulate a retrieved video corresponding to an displayed video snippet based on matching corner feature information of the displayed video snippet generated and provided by a server and corner features of the video of the real-world scene, wherein the retrieved video is retrieved with metadata having selected features;combine the manipulated retrieved video with a currently observed real-world scene viewed with the portable electronic device; andprovide guide information related to the selected features;wherein the retrieved video is manipulated by applying a transformation matrix to a plurality of nested views of the retrieved video, wherein the transformation matrix approximates a perspective distortion caused by a movement of the camera.

A computer program product for providing an augmented reality interface, comprising a non-tangible computer readable medium tangibly embodying non-transitory computer-executable program instructions thereon that, when executed, cause a computing device to:npreload a plurality of video snippets from a server based on a location of a location information of a portable electronic device, each of the plurality of video snippets being a smaller video file of a corresponding stored video;acquire a video of a real-world scene and metadata with a camera of a portable electronic device;overlay one or more of the plurality of video snippets corresponding to a location and a direction at which a corresponding video was originally captured based on the location information and a orientation information of the portable electronic device without manipulating the plurality of video snippets based on corner features of the video of the real-world scene;manipulate a retrieved video corresponding to an displayed video snippet based on matching corner feature information of the displayed video snippet generated and provided by the server and corner features of the video of the real-world scene, wherein the retrieved video is retrieved with metadata having selected features;combine the manipulated retrieved video with a currently observed real-world scene viewed with the portable electronic device; andprovide guide information related to the selected features;wherein the retrieved video is manipulated by applying a transformation matrix to a plurality of nested views of the retrieved video, wherein the transformation matrix approximates a perspective distortion caused by a movement of the camera.

A system for providing an augmented reality interface, comprising:nmeans for preloading a plurality of video snippets from a server based on a location of a location information of a portable electronic device, each of the plurality of video snippets being a smaller video file of a corresponding stored video;means for acquiring a video of a real-world scene and metadata with a camera of a portable electronic device;means for overlaying one or more of the plurality of video snippets corresponding to a location and a direction at which a corresponding video was originally captured based on the location information and an orientation information of the portable electronic device without manipulating the plurality of video snippets based on corner features of the video of the real-world scene;means for manipulating a retrieved video corresponding to an displayed video snippet based on matching corner feature information of the retrieved video generated and provided by the server and corner features of the video of the real-world scene wherein the retrieved video is retrieved with metadata having selected features;means for combining the retrieved manipulated video with a currently observed real-world scene viewed with the portable electronic device; andmeans for providing guide information related to the selected features;wherein the means for manipulating the retrieved video comprises means for applying a transformation matrix to a plurality of nested views of the retrieved video, wherein the transformation matrix approximates a perspective distortion caused by a movement of the camera.
