Distance and height measurement between insulators in steel tower

Take multiple steel tower images from drone and pick up two images and measure distances
Input standard point will make measurement more accurate and measurement anywhere on images possible

Procedure1) Standard point confirmation

Procedure2) Distance measurement (insulators)

Procedure3) Change of standard point

Procedure4) Distance measurement (height)

Creation of 3d point cloud

This system can calculate camera position automatically and create 3d point cloud.
