How to Plan a 3D Photogrammetry Mission in GS RTK: Multi-oriented


Before getting started with planning a 3D mission, please contact your Customer Success Engineer. This is a feature that must be turned on prior to uploading your data to the platform.  Since 3D missions differ from 2D missions with both data capture and data upload, your CSE will go over best practices and processing times with you.

3D multi-oriented missions involve a single flight directly overhead of the site with the camera facing straight down (nadir). This is followed by four flight paths with images captured at different camera angles (oblique) for a total of five segments. The oblique segments are optional and can be toggled on or off depending on the requirements of the mission.

This mission type should only be used in specific circumstances, namely when you are flying in a mine or quarry and you need more detail and accuracy on the vertical faces. Please work with your Customer Success Engineer to determine the best mission type for your site

For example, if you need an accurate model of a bench for blasting planning, this mission type can provide a more accurate point cloud than a laser scan of the vertical face, allowing for safer blasting. 

Use the steps below to plan a 3D multi-oriented mission 

1. Tap 3D Photogrammetry (Multi-oriented).

 

2. Locate your site by panning around the map. Use two fingers to adjust the zoom.

3. Drop a pin by tapping the boundary of your site to start creating your survey area. 

4. Drop a minimum of three pins to produce a survey area. To move a pin, tap it again and either use the wheel on the right or drag the pin with your finger. Delete a selected pin by double-tapping it or tapping the trash icon.

Before you can change the mission settings, you must mark your survey boundaries. 

5. Display the mission settings by tapping on the white tab on the right side of the screen. 

Important You can change the settings for individual segments of the mission by tapping on the circled numbers. 

In the first screenshot below, section 1 is selected and appears white. The other segments are gray. In the second screenshot, section 5 (one of the oblique flights) is selected. 

The settings listed below are a good guideline for planning 3D multi-oriented photogrammetry missions.

 

6. Tap Save and give your task a name.
