    摘要: Panoramic video acquisition guidance is automatically provided as feedback during panoramic video capture. Commensurate with receiving a panoramic video being captured, at least one panoramic video acquisition guidance indicator is provided. This panoramic video guidance acquisition indicator(s) provides real-time acquisition feedback on the panoramic video being captured, and is based, at least in part, on the panoramic video being captured or movement of a video capture device capturing the panoramic video. In one or more implementations, the panoramic video guidance indicator may include a video rotation progress indicator, a video tilt or video pitch indicator, and/or a video rotation speed indicator.

    摘要: An indoor area may be localized to provide end users with a mobile-accessible map to guide the end user in navigating the indoor area. A preliminary version of a map of the indoor area to be localized is processed to identify different navigable routes within the indoor area. A user may access the processed map and collect sensory data using the mobile device while moving along any of the navigable routes. The different sensory data that is collected at the same moment in time may be associated based on the location of the mobile device when the data is collected. The localized map is then generated with visual indications of the locations of the corresponding sensory data. The end user may then access the localized map on a mobile device to navigate the indoor area and to locate specific points of interest corresponding to the sensory data.

    摘要: Systems and methods provide approximations of latitude and longitude coordinates of objects, for example a business, in street level images. The images may be collected by a camera. An image of a business is collected along with GPS coordinates and direction of the camera. Depth maps of the images may be generated, for example, based on laser depth detection or displacement of the business between two images caused by a change in the position of the camera. After identifying a business in one or more images, the distance from the camera to a point or area relative to the business in the one or more images may be determined based on the depth maps. Using this distance and the direction of the camera which collected the one or more images and GPS coordinates of the camera, the approximate GPS coordinates of the business may be determined.

    摘要: A method for creating a three-dimensional mesh model of a structure includes accessing a set of three-dimensional points associated with a set of images of the structure. For each three-dimensional point in the set of three-dimensional points, the method determines a reference image, identifies a subset of images from the set of images of the structure taken within a distance from the reference image, determines a subset of three-dimensional points seen by the subset of images, filters the subset of three-dimensional points to retain only a set of co-visible points that lie in a visibility cone of the reference image, and selects a normal using the set of co-visible points. The three-dimensional mesh model of the structure is computed using the selected normal, and the model may be provided to a second computing device.

    摘要: Methods and systems permit automatic matching of videos with images from dense image-based geographic information systems. In some embodiments, video data including image frames is accessed. The video data may be segmented to determine a representative image frame of a segment of the video data. Data representing information from the representative image frame may be automatically compared with data representing information from a plurality of image frames of an image-based geographic information data system. Such a comparison may, for example, involve a search for a best match between geometric features, histograms, color data, texture data, etc. of the compared images. Based on the automatic comparing, an association between the video and one or more images of the image-based geographic information data system may be generated. The association may represent a geographic correlation between selected images of the system and the video data.

    摘要: Aspects of the present disclosure provide systems and methods for generating models of a wireless network environment in an indoor space which may be used to predict an indoor location. The disclosure relates to collecting wireless network access point identifier information and power level observed at various locations are collected to generate various signal maps. The signal maps may be used to generate models of the indoor space. In one example, a voting model may use a probability distribution of a plurality of signal maps in order to identify a location with a highest probability of overlap with current signals received at a client device. Once a location has been identified, it may be used to assist with any number of navigational functions, such as providing turn by turn directions to another indoor location, for example, a conference room or exit, or simply providing information about the current location.
