    摘要: A cross reality system enables any of multiple devices to efficiently and accurately access previously persisted maps of very large scale environments and render virtual content specified in relation to those maps. The cross reality system may build a persisted map, which may be in canonical form, by merging tracking maps from the multiple devices. A map merge process determines mergibility of a tracking map with a canonical map and merges a tracking map with a canonical map in accordance with mergibility criteria, such as, when a gravity direction of the tracking map aligns with a gravity direction of the canonical map. Refraining from merging maps if the orientation of the tracking map with respect to gravity is not preserved avoids distortions in persisted maps and results in multiple devices, which may use the maps to determine their locations, to present more realistic and immersive experiences for their users.

    摘要: Techniques for determining map data for localizing a vehicle in an environment are discussed herein. A vehicle can capture sensor data such as image data and can detect objects in the sensor data. Detected objects can include semantic object such as traffic lights, lane lines, street signs, poles, and the like. Rays based on a pose of the sensor and the detected objects can be determined. Intersections between the rays can be determined. The intersections can be utilized to determine candidate landmarks in the environment. The candidate landmarks can be utilized to determine landmarks and to eliminate other candidate landmarks. The map data can be determined based on the three-dimensional locations and utilized to localize vehicles.

    摘要: An autonomous driving device includes a first map including a first content and a second content associated with positions respectively, a second map including the first content associated with the position and in which the second content is not a recording target, and a control unit performing the autonomous driving. When the autonomous driving is performed using the first map, the control unit determines information necessary for the autonomous driving using a first method based on the first content and the second content. When the autonomous driving is performed using the second map, the control unit determines the information necessary for the autonomous driving using a method same as the first method based on the first content corresponding to a second position recorded in the second map and information indicating that the second content corresponding to the second position recorded in the second map is not present.

    摘要: A map generation apparatus includes: an in-vehicle detection unit configured to detect a situation around a subject vehicle in traveling; and a microprocessor and a memory connected to the microprocessor. The microprocessor is configured to perform: extracting one or more feature points from a detection data acquired by the in-vehicle detection unit; generating a map using the feature points extracted in the extracting while the subject vehicle is traveling; collating the feature points extracted in the extracting with the map to recognize a position of the subject vehicle on the map when the subject vehicle travels in a region corresponding to the map; and deleting, from the map, a feature point whose result of collation in the recognizing is less than a predetermined degree among the feature points included in the map.

    摘要: A vehicle controller includes a processor configured to detect an inconsistent section where information on a road represented in a first map is inconsistent with information on the road represented in a second map, make a first driving plan for a first section from a current position of a vehicle to a control switching point which is a start point of the inconsistent section or is nearer the vehicle than the start point, based on one of the first and second maps, make a second driving plan for a second section beyond the control switching point including the inconsistent section, based on the other of the first and second maps, before the vehicle reaches the control switching point, and control the vehicle so as to follow the first driving plan on the first section and follow the second driving plan on the second section.
