    摘要: A mapping device receives a request for localization using current sensor data which is image-based sensor data or structure-based sensor data, access image-based map elements and structure-based map elements, each map element being associated with a capturing time indicating a time of capturing the sensor data based on which it was derived, identify pairs of corresponding map elements, each pair including an image-based map element and a structure-based map element representing features at the same real-world location, and for each pair of corresponding map elements: determine an information difference metric between the image-based map element and the structure-based map element, and select one of the map elements of the pair of corresponding map elements for updating the heterogenous map based on a comparison of the respective capturing times, a type of the current sensor data, and the information difference metric.

    摘要: Techniques are disclosed for systems and methods to provide assisted navigation based on surrounding threats. In one example, an assisted navigation system receives data from a plurality of sensors associated with a mobile structure. The assisted navigation system determines a plurality of navigational hazards disposed within a monitored area associated with the mobile structure. The assisted navigation system processes the data and/or the navigational hazards to determine an operational context of the mobile structure. The assisted navigation system generates a context-dependent navigational chart for the mobile structure, wherein the navigational chart comprises greater or fewer of the navigational hazards in response to the determined operational context. The assisted navigation system updates the navigational chart in response to changes in the data. Additional systems and methods are provided.

    摘要: A route determination system according to the present application includes: a terminal device serving as a reference of a route for a mobile object; and a determination apparatus. The terminal device has an obtaining unit that obtains correction information generated on the basis of data received from an artificial satellite, and a calculation unit that calculates position information on the terminal device on the basis of the correction information obtained by the obtaining unit. The determination apparatus has a determination unit that determines a movement route for a mobile object on the basis of the position information calculated by the calculation unit.
