Method, apparatus, and system for providing an item image to a client for display in a contextual environment are described. In some embodiments, the user may select an item for display in the contextual environment, and the user may position a camera coupled to a processing system to capture the contextual environment. A marker may be generated and associated with an item selected by a user. In an embodiment, the generated marker may be placed in a location within the contextual environment, and the user's processing system may send a visual data stream of the camera-captured environment to a server. In an embodiment, the user's processing device may receive a modified data stream including an image of the item, and the user's processing device may display the item image in the same location as the marker.

A system and method for ground truth estimation of an autonomous navigation system is described. The method includes calibrating a ground truth estimation system for the navigator, by determining a calibration pose of the navigator as disposed in relation to each of a plurality of landmarks during a calibration period. The method also includes directing the navigator to travel to a sequence of waypoints, the waypoints including a selected sequence of the landmarks. The method further includes determining the ground truth estimation based on an accuracy pose of the navigator as disposed in relation to the sequence of landmarks, and the calibration poses for the sequence of landmarks.

In various example embodiments, a system and method for visualization of an item in an environment using augmented reality is provided. In example embodiments, environment image data containing an image of an environment is received from a client device. A selection of an item that is under consideration for purchase and placement into an indicated location of the environment is received. An item image of the selected item is scaled to a scale that is based on dimensions determined from the environment image data for the environment. The scaled item image is augmented into the image of the environment at the indicated location to generate an augmented reality image.

There are provided a landmark for recognizing a position of a mobile robot moving in an indoor space and an apparatus and method for recognizing the position of the mobile robot by using the landmark. The landmark includes a position recognition part formed of a mark in any position and at least two marks on an X axis and Y axis centered on the mark and further includes an area recognition part formed of a combination of a plurality of marks to distinguish an individual landmark from others. The apparatus may obtain an image of the landmark by an infrared camera, detect the marks forming the landmark, and detect precise position and area information of the mobile robot from the marks.

A method and apparatus for estimating a position and an orientation of a mobile robot. The apparatus includes: a ceiling image grabber for obtaining a ceiling image of an area where the mobile device travels; a mark detector for detecting a retro-reflective artificial mark from the ceiling image, the retro-reflective artificial mark including a first mark and a second mark, each including a non-reflective portion and an infrared reflective portion; and a position & orientation estimator for estimating a position and an orientation of the mobile device using a position of the artificial mark or encoder information according to whether detection of the artificial mark is successful.

PROBLEM TO BE SOLVED: To provide an artificial mark generating method applied to an environment where lighting is poor or lighting brightness heavily changes, an estimation method for an own position and a direction angle of a moving robot, an estimation device, and an estimation program. SOLUTION: This estimation device for an own position and a direction angle of the moving robot is equipped with a ceiling image acquisition part, a mark detection part, and a position and direction angle estimation part. The image acquisition part acquires a ceiling image of a place where the moving robot travels while the detection part detects the position of an artificial mark from the ceiling image. The estimation part estimates the position and direction angle of the moving robot based either on information on the position of the artificial mark or on information acquired by an encoder sensor. The artificial mark comprises first and second marks, the second mark being spaced apart from the first mark by a prescribed distance. The first and second marks each have a non-reflection portion and an infrared reflection portion, the reflection portion recursively reflecting infrared rays. COPYRIGHT: (C)2005,JPO&NCIPI
