用于通路传感器数据的数据过滤的系统和方法
摘要：
一种用于通路传感器数据的数据过滤的系统和方法包括利用柔性细长装置穿过多个通路，并且在穿过期间使用耦接到柔性细长装置的一个或多个传感器记录位置数据。位置数据包括在柔性细长装置进入第一通路的第一插入期间所记录的第一多个位置数据点和在柔性细长装置在第一通路内的第一缩回期间所记录的第二多个位置数据点。所述系统和方法还包括将第一多个位置数据点和第二多个位置数据点标记为第一共同通路位置数据点并且将位置数据与多个通路的模型配准，其中配准包括将第一共同通路位置数据点与对应的第一共同通路模型数据点匹配。
摘要（英）：

A system and method for data filtering of passageway sensor data include traversing a plurality of passageways with a flexible elongate device and recording, during the traversing, positional data using one or more sensors coupled to the flexible elongate device. The positional data includes a first plurality of positional data points recorded during a first insertion of the flexible elongate device into a first passageway and a second plurality of positional data points recorded during a first retraction of the flexible elongate device within the first passageway. The system and method further include labeling the first plurality of positional data points and the second plurality of positional data points as first common passageway positional data points and registering the positional data with a model of the plurality of passageways, wherein the registering includes matching the first common passageway positional data points with corresponding first common passageway model data points.
