Extract by Segmentation

Functional Overview

The Extract by segment tool extracts point clouds based on user-selected ranges of integer single-component additional attributes. This feature currently only supports the processing of a single point cloud.

Usage

Click Data Management > Point Cloud Tools > Extract by segment

Parameters Settings

• Point Cloud: Select the point cloud data file, currently only one point cloud data is supported. File format: *.LiData.
• Select Label: The user needs to select the additional attribute name from the checkbox as the label. The label must be integer but component. This function cannot be run if the point cloud data does not contain additional attributes of integer single component. The selected additional attributes will be used as tags, and points with the same tags will be extracted as a file. Assuming that LiData contains an integer single-component additional attribute A,in which the A attribute value of 10 points is "1", and the A attribute value of 20 points is “2”,then the function will generate two files C after running. (including 10 points, the attribute is "1") and D (including 20 points, the attribute is "2");
• Range Selection: Select the range of labels. Only point clouds whose labels are within this range are extracted.
• Export Format: The format for exporting point clouds, currently DXF and Las are supported.
• Output Path: The path of the extracted output file after the function is executed.
