Linear Inspections with Hammer

Overview

Whatever your use-case, Hammer can adapt to it.

Tutorial

  1. Horizontal Inspection — of buildings, roofs, and other infrastructure.
  2. Linear Inspection — of pipelines, railroads, rivers and other linear objects.
  3. Vertical Inspection — of building walls, cliffs and other vertical structures.

Linear Inspection

In this mission, Hammer calculates picture points on top of a user-defined line and flies the drone to these points maintaining a constant altitude throughout the mission. The drone stops at every point in the mission, adjusts its heading to match the line’s heading and takes a high resolution picture of the linear structure.

Steps to Create

  1. Tap on the add(+) button in the top right corner.
  2. Choose ‘Linear Inspection’ from the missions view
  3. Draw a line over the area to be inspected.

Note: A line can also be drawn by flying the drone to the appropriate GPS coordinates and tapping the back (right) button on the remote controller.

4. Once you are happy with the line, click OK on the right panel.

This will generate a dotted string of points on top of the line.
