The present disclosure relates to a control device, a control method, and a mobile object that effectively use storage capacity while saving the storage capacity and efficiently plan a movement route by storing or forgetting (deleting) a past detailed map according to importance during autonomous movement. When a global route is set, by storing or forgetting (deleting) a detailed map according to the importance on the global route to plan a local route from a frequently used global route, it is possible to efficiently plan a local route by combining detailed maps stored in the past.

A digital map representing a physical location as a hierarchical structure of cells. Each cell has attributes including but not limited to permeability in each direction of a three-dimensional coordinate system and associated with one or more faces or edges of a boundary. The permeability pertains separately to transmissions of radio frequency signals and to physical travel of objects and persons.

An approach is provided for mapping a parking facility using multi-modal trajectories collected using mobile device(s). The approach, for example, involves collecting sensor data from sensor(s) of mobile device(s). The sensor data represents the multi-modal trajectories comprising (1) vehicle trajectory segments during which the device(s) traveling into/out of a parking facility, and (2) pedestrian trajectory segments during which the device(s) traveling to/from pedestrian entry/exit point(s) of the parking facility. The approach also involves processing the sensor data to determine semantic event(s) associated with parking in the parking facility based on the multi-modal trajectories. The approach further involves determining parking spot location(s) and/or orientation(s) of the parking facility based on the semantic event(s). The approach further involves generating map data indicating the parking spot location(s) and/or orientation(s). The approach further involves providing the map data as an output.

A system and method for monitoring safety of an environment is provided. The system includes a plurality of sensors, a non-transitory memory storing an executable code, and a hardware processor executing the executable code to receive a first input from a first sensor, the first input including a first current condition information, compare the first current condition information with a current condition database, receive a second input from a second sensor, the second input including a second current condition information, compare the second current condition information with the current condition database, determine an event based on the comparison of the first current condition with the current condition database and the comparison of the second current condition with the current condition database, and transmit a signal in response the determination of the event.

An indoor location is mapped into a grid comprising grid cells, each cell associated with items or objects detected as being present in the corresponding cell. The grid, grid cells, and linked items and/or objects are generated and updated using an Augmented Reality (AR) algorithm that maps a physical environment into cells and measures distances and directions within the environment relative to each cell. Walking paths (routes) to the items within the indoor location are generated using the grid information. As a user walks a path, the user's position within the indoor location is mapped and tracked to the cells and the path revised based on the user's actual position. A user device provides video via an AR application to track the user's position; a rendering of the position and path are superimposed within the video being viewed by the user on the user-operated device.

A security monitoring system may implement a building space mapping process using a drone. The process involves generating a floor plan of the building space by performing pre-mapping and detailed mapping protocols, and allowing the user to specify particular areas of interest that may restrict or enhance the drone's ability to move through the building space. The drone may generate and travel along a trajectory path based on the floor plan and information collected during the mapping protocols.

In implementations of systems for generating indications of traversable paths, a computing device implements a navigation system to receive map data describing a map of a physical environment that includes a destination, locations of display devices and relative orientations of the display devices in the physical environment. The navigation system forms a navigation graph by representing the destination and the locations of the display devices as nodes of the navigation graph and connecting the nodes with edges that indicate traversable path segments in the physical environment. Request data is received describing a request for navigation to the destination and a source of the request. The navigation system generates indications of a traversable path to the destination for display by the display devices based on the navigation graph and the relative orientations of the display devices.

Provided are embodiments for a system and method for performing real-time detection for mapping. The embodiments include one or more processors, a scanner, and a mobile computing device removably coupled to the 2D scanner where the mobile computing device having a display.
