    • A system includes a transformation module, alignment module and aligned localization module. The transformation module is configured to receive first and second pose estimates of a mobile platform movable within an environment. The first and second pose estimates are relative to different, respective first and second digital maps of the environment in different, respective first and second coordinate systems. The transformation module, then, may be configured to calculate a geometric transform between the first and second digital maps based on the first and second pose estimates. The alignment module may be configured to align the first and second digital maps based on the geometric transform, and thereby generate an aligned digital map. And the aligned localization module may be configured to localize the mobile platform relative to the aligned digital map, and thereby calculate an aligned pose estimate of the mobile platform.
    • 系统包括转换模块,对准模块和对准的定位模块。 变换模块被配置为接收在环境内可移动的移动平台的第一和第二姿态估计。 第一和第二姿势估计是相对于不同的,相应的第一和第二坐标系中的环境的不同的,相应的第一和第二数字地图。 然后,变换模块可以被配置为基于第一和第二姿势估计来计算第一和第二数字地图之间的几何变换。 对准模块可以被配置为基于几何变换对准第一和第二数字地图,从而生成对准的数字地图。 并且对齐的定位模块可以被配置为相对于对准的数字地图本地化移动平台,并且由此计算移动平台的对准姿态估计。
