A map image is displayed via a user interface. A user selection of a location marker or one of a set of textual driving directions is received via the user interface. In response to the received user selection, an interactive information window overlaid within the map image is generated. Generating the interactive information window includes providing additional information regarding a location related to the marker or to the one of the set of textual driving directions.

The present invention relates to a method and a system for creating a map based on 3D laser. The method for creating a map comprises: planning a route, and acquiring data in a movement process of a mobile robot; loading acquired data by using a map creating tool; performing initial alignment to adjacent laser data; performing accurate alignment to the adjacent laser data; performing closed-loop association to the same area passed through by the mobile robot, and establishing a closed-loop constraint; performing global optimization solution to an entire map for which the closed-loop constraint is established; and superposing all laser data, and outputting a laser map. The present invention does not depend on GPS and is not restricted by GPS signals; no surveying and mapping device such as a total station is used, and cumbersome surveying and mapping operations are avoided; a manual loop closing method can be used, and large-scale maps of various indoor and outdoor environments can be created; and data acquisition can be separated from map creation, maps can be finely adjusted off line, and high-accuracy maps can be created.

A management system 1 for a work machine includes: a plurality of dump trucks 2 each creating a map information piece DTI of a sectioned region DT around the own vehicle; and a management device 10 that manages map information pieces DTI of a plurality of sectioned regions DT created by the plurality of dump trucks 2 and transmits, to each of the dump trucks 2, a map information piece DTI of a sectioned region DT where each of the dump trucks 2 exists and a map information piece DTI of a sectioned region DT adjacent to the sectioned region DT where each of the dump trucks 2 exists on the basis of information related to a position of each of the dump trucks 2.

Embodiments of the disclosure provide systems and methods for updating a high-resolution map. The system may include a communication interface configured to receive a plurality of image frames captured by a binocular camera equipped on a vehicle, as the vehicle travels along a trajectory. The system may further include a storage configured to store the high-resolution map and the plurality of image frames. The system may also include at least one processor. The at least one processor may be configured to generate point cloud frames based on the respective image frames. The at least one processor may be further configured to position the vehicle using the point cloud frames. The at least one processor may be further configured to merge the point cloud frames based on the vehicle positions. The at least one processor may also be configured to update a portion of the high-resolution map based on the merged point cloud.

In response to confirmation request from an onboard terminal in a state where updated data after start of a temporary road change is available, a map update server distributes the updated data and instructs the onboard terminal to temporarily use the updated data. In response to the confirmation request in a state where the updated data after end of a temporary road change is available, the server instructs the onboard terminal to use the updated data from before the start of the temporary road change. In response to being instructed to temporarily use the updated data, the terminal uses the updated data that has been distributed. In response to being instructed to use the updated data from before the start of a temporary road change, the terminal temporarily uses the updated data by using map data from before the start of the temporary road change instead of the updated data.

A mobile assistance system includes: a mobile assistance terminal to be mounted on a mobile body and configured to acquire mobile body peripheral information as information on a periphery of the mobile body; and a mobile assistance apparatus configured to update map information, based on the mobile body peripheral information transmitted from the mobile assistance terminal.

A map image is displayed via a user interface. A user selection of a location marker or one of a set of textual driving directions is received via the user interface.

A method is provided for setting, by a processor, a minimum and maximum symbol size for rendering at different zoom levels on a digital map. In another embodiment of the invention, the size of overlay features, such as line widths, received by a processor is automatically adjusted for different zoom levels depending on the average size of map features, such as polygons. In one example, line widths are decreased, and/or made partially transparent, as the map views are zoomed out, finally being altogether eliminated. In one embodiment, the system automatically analyzes received data to determine an appropriate way to map the data.

An identification unit obtains a plurality of photographic images including two or more markers. The makers are placed on a different object, respectively. The identification unit identifies, from the plurality of photographic images thus obtained, three-dimensional positions of the two or more markers. A generating unit transforms coordinate system of the plurality of photographic images into a common coordinate system. Relative positions of the two or more markers based on a specific location are indicated in the common coordinate system. The generating unit generates map data which associates the positions of the two or more markers.

Techniques are disclosed for collaborative map construction using multiple vehicles. Such a system may include a ground vehicle including a first computing device and a first scanning sensor, and an aerial vehicle including a second computing device and a second scanning sensor. The ground vehicle can obtain a first real-time map based on first scanning data using the first scanning sensor, and transmit a first real-time map and position information to the aerial vehicle. The aerial vehicle can receive the first real-time map and the position information from the first computing device, obtain a second real-time map based on second scanning data collected using the second scanning sensor, and obtain a third real-time map based on the first real-time map and the second real-time map.
