摘要： Aspects of the disclosure provide methods and mobile robots for providing information to a pedestrian. In some examples, a mobile robot includes processing circuitry. The processing circuitry obtains, via a sensor, sensing data that indicates an ambient environment of the mobile robot. The processing circuitry determines path indication information according to the sensing data. The path indication information includes a planned path of the mobile robot. The processing circuitry projects the path indication information on a target projection surface.

摘要： A method and an apparatus for displaying a statistical chart. The method includes determining whether a screen rotation event of switching from portrait-orientation display to landscape-orientation display is received. The method further includes obtaining additional to-be-shown data added during switch from a portrait-orientation-display drawing area to a landscape-orientation-display drawing area if yes, and drawing the landscape-orientation-display drawing area. The method further includes displaying a statistical chart in the drawn landscape-orientation-display drawing area, where the additional to-be-shown data is shown in the statistical chart. A statistical chart fills a drawing area in a landscape-orientation state.

摘要： A method and device for panorama-based inter-viewpoint walkthrough and a machine readable medium are provided. The method includes: selecting a current viewpoint image from a panorama, and obtaining a three-dimensional model of the current viewpoint image; selecting a sub-image from the current viewpoint image to perform a feature detection, so as to obtain feature points of neighboring viewpoints; performing a matching calculation on the feature points of the neighboring viewpoints, and determining a distance between the neighboring viewpoints according to a result of the matching calculation; and performing three-dimensional walkthrough on the three-dimensional model of the current viewpoint image, where a walkthrough depth is the distance between the neighboring viewpoints. After application of the embodiments of the present disclosure, smooth panorama-based inter-viewpoint transition can be realized, and the effect of smooth walkthrough can be enhanced, by accurate determination of distance between the viewpoints.

摘要： Transitions between street view images are described. The described techniques include: obtaining an original street view image and a target street view image; constructing a three-dimensional model corresponding to the original street view image by three-dimensional modeling; obtaining matching pairs of feature points that are extracted from the original street view image and the target street view image, and simulating a virtual camera in the three-dimensional model according to matching pairs of feature points to capture street view image sequence; and switching from the original street view image to the target street view image according to the street view image sequence. Transition stability is thereby improved.
