A map display method comprises: obtaining room map data and regional map data; drawing a room map according to the room map data, and drawing a regional map layer on the room map according to the regional map data; and displaying the room map that is covered by the regional map layer.

A method performed by a computing system for driving in a group includes determining a plurality of mobility devices included in a first group for group driving. The method also includes identifying a leading device among the plurality of mobility devices included in the first group. The method additionally includes transmitting first route information set in a navigation of the leading device to a trailing device included in the first group together with the leading device. The method further includes setting a first route based on the first route information in a navigation of the trailing device. The method further still includes transmitting second route information set in the navigation of the leading device to the trailing device in response to the leading device deviating from the first route. The method additionally includes setting a second route based on the second route information in the navigation of the trailing device.

A driving assistance method for assisting driving of a mobile machine, the driving assistance method includes: executing processes of, by one or more processors, acquiring at least one of a first position on an autonomous driving route and a first angle indicating a direction in which the mobile machine travels at the first position when the mobile machine deviates from the autonomous driving route by switching from autonomous driving to manual driving, and outputting driving assistance information for assisting the manual driving according to at least one of a difference between the first position and a second position that is a position of the mobile machine traveling by the manual driving, and a difference between the first angle and a second angle indicating a direction in which the mobile machine is traveling at the second position.

A map display method comprises: obtaining room map data and regional map data; drawing a room map according to the room map data, and drawing a regional map layer on the room map according to the regional map data; and displaying the room map that is covered by the regional map layer.

An operation system performs autonomous operation by using an operation server for an autonomous driving vehicle. The operation server includes a memory unit containing three-dimensional map data. An autonomous driving vehicle connects to the operation server via a wireless network. A vehicle control unit creates a traveling route based on the map data received and, when an elevator of a building is to be used, creates elevator usage information and elevator control information, including the boarding and exiting floors. The elevator is equipped with an elevator control unit that is connected to the operation server to control ascending and descending of an elevator cage. A control unit of the autonomous driving vehicle transmits the elevator usage information and the elevator control information to the elevator control unit. The elevator control unit gives a voice announcement from a voice output unit in the elevator cage.

Provided are a system and method for intelligently interpreting an exhibition scene. The system is configured for automatically following an interpretation user or a visitor by means of an intelligent following apparatus, so as to improve visiting experience of the visitor. The system includes a positioning apparatus and the intelligent following apparatus, the positioning apparatus is configured for determining positioning information of target users, and the intelligent following apparatus is configured for following the target users to move according to the positioning information of the target users.

A remote support system is a remote support system for one remote operator to remotely support a plurality of mobile objects. The remote support system includes a situation acquisition unit, a support difficulty level calculation unit, and a notification unit. The status acquisition unit acquires the work status of the remote operator based on information transmitted from an operator interface operated by the remote operator. The assistance difficulty level calculation unit calculates the assistance difficulty level of the remote operator based on the work status of the remote operator. The notification unit notifies the mobile objects of the assistance difficulty level.

A system and method for animating and displaying images via a mobile robot. The mobile robot includes a screen and a processor wherein the processor executes computer readable commands, thereby displaying animations onto the screen. The method includes the steps of creating animations as GIF files, converting images into code, optimizing frame sequence, translating optimized frames into a C programming data structure, and displaying the optimized frames onto the screen of the mobile robot.

Provided are a map drawing method, a map drawing device, a computer-readable storage medium and an electronic apparatus. The map drawing method comprises scanning a boundary of a surface medium region to generate an initialized region; merging boundary coordinates of the initialized region to obtain a merged region; dividing the merged region into a plurality of sub-regions according to a preset shape; and drawing the boundary of the surface medium region based on the sub-regions and the merged region to obtain a map of the surface medium region. The method can improve the detailedness of the drawn map of the surface medium region.
