Insulator Vectorization

Insulator Vectorization Toolbar is as below, including Hang Insulator, Modify Insulator, Auto Hang Insulator.

Hang Insulator

Vectorize insulator. Click Hang Insulator button and a window will pop up. The operation steps are as below:

• Clip Tower: Uncheck by default. If check this function for editing convenience, then the point cloud file will be clipped into several separate files by tower mark and buffer size.
• Buffer Size (meter, 10 by default): The half length of the XY plane of the cutting bounding box is used to control the size of the cutting area.
• Current Tower Index: Index of tower being edited.
• Insulator Length (meter, 3 by default): Insulator length of straight tower.
• Translate X (meter, 0.1 by default): Set translation distance along X-axis of the last drawn insulator.
• Translate Y (meter, 0.1 by default): Set translation distance along Y-axis of the last drawn insulator.
• Translate Z (meter, 0.1 by default): Set translation distance along Z-axis of the last drawn insulator.

1. Set tower type and enter tower index corresponding to towers in viewer.
2. Use length measurement tool to measure the length of insulator and set average length as insulator length.
3. Left click to pick up hang point(point connecting insulator and power line). For tension tower, insulator is vectorized as point; for straight line tower, insulator is vectorized as line.
4. Vectorize next insulator, or right click to exit insulator vectorization.

Modify Insulator

Edit position of selected insulator, the operation steps are as below:

• Translate X (meter, 0.1 by default): Set translation distance along X-axis of the selected drawn insulator.
• Translate Y (meter, 0.1 by default): Set translation distance along Y-axis of the selected drawn insulator.
• Translate Z (meter, 0.1 by default): Set translation distance along Z-axis of the selected drawn insulator.

1. Click Modify Insulator button, then click and select the insulator to be edited. Set edit parameters in the pop up window.
2. Click the right mouse button to hide the dialog and continue to modify the next insulator.
3. After the modification is completed, right-click again to exit the function.

Auto Hang Insulator

In order to automatically hang insulators, it is necessary to first classify powerlines, towers, and insulators.

• Insulator Length(meter, 3.0 by default): Set the insulator length for straight line towers.
• Clustering Threshold(meter, 4.0 by default): Set the clustering calculation radius for insulators.
• Elevation Compensation(meter, 0.0 by default): Set the elevation compensation of conductor end hanging point.
• Extract Tower End Hanging Point: Unchecked by default. When checked, tension tower insulators are hung at the tower end.
• Extract Lowest Hanging Point: Unchecked by default. When checked, hanging point of conductor end is hung lowest point near the powerline.

Note: When the voltage level of the detection line in the Engineering Configuration is less than or equal to 10kV, it is a distribution network line and does not require insulator point classification or insulator length parameters.

Note: please add in corresponding tower file(*.LiTower) before using insulator vectorization tools.
