Using Propeller PPK with the Anzu Raptor


If you fly an Anzu Raptor, you can use the Propeller PPK workflow to process the images with high accuracy (5-10cm). 

Data Capture

Review these considerations when using an Anzu Raptor to produce the most accurate model possible. 

Ground Control

AeroPoint 2s are required for all situations when processing Anzu Raptor data with Propeller PPK. 

AeroPoint 1s are not compatible with the Anzu Raptor + Propeller PPK workflow.

Camera and Mission Settings

If you have questions about troubleshooting, drone setup, using Anzu Raptor, etc., please refer to the Anzu FAQ page or review our Anzu Raptor Support Article for additional resources. Anzu support can be reached by email at info@anzurobotics.com.

Propeller recommended mission settings

Camera Settings Set to Question to Ask Yourself Reason
Camera mode Manual Do I want all of the photo settings to automatically adjust, or do I need to set certain settings? Setting to Manual allows the pilot to adjust required settings, like Shutter Speed.
Auto Exposure (AE) Unlocked How bright do I want my images? You want your ISO to adjust to the conditions of the day.
Shutter 1/1000 How fast should the shutter close? 1000 is usually a good place to start for sunny conditions. In low light conditions, reduce the shutter speed to ~1/800 and lower the speed.
Camera Slider Bars Set to Question to Ask Yourself Reason
Image ratio 4:3 How much of the image should I delete? 4:3 deletes nothing, utilizing the whole sensor. Everything else deletes data.
Image format JPEG How should the images be saved? Images must be in a JPG format to upload to Propeller.
Lock Gimbal While shooting On Do you want the gimbal to lock in place while it takes a photo? Leave this on its default setting. This will help prevent blurry images.
Mechanical Shutter On Do I want my camera to use the mechanical shutter? A mechanical shutter uses the conventional front and rear shutter curtains at the front of the sensor. Not using the mechanical shutter will introduce distortion.
All other settings Leave on Default Are these settings related to the mission I am flying? We have found any remaining settings do not need to be adjusted for optimal data collection.
       
Mission Setting Set to Question to Ask Yourself Reason
Aircraft Model Raptor Series Which drone am I flying? Anzu uses the same Aloft Interface for the Raptor T series.
Camera Model Raptor Which camera are you planning to use for this mission? Mission options can vary based on the camera type selected. Be sure to select the correct camera type.
Lens WIDE Which Lens am I using? The mission parameters will differ for different lenses, so ensure this is set accurately.
Ortho/Oblique Collection Ortho Collection Am I performing a 2D photogrammetry mission? In a 2D photogrammetry mission, the camera should only face straight down for the entire mission.
Ortho GSD *Default   *The Ortho GSD will change depending on your mission height. Once you set the Route Altitude, the Ortho GSD will be set accordingly. Changing the GSD setting will automatically change your mission height settings.
Altitude Mode Relative to Takeoff Point (ALT) What elevation is your mission altitude referring to? Unless you are referencing to altitude above sea level (ASL) in the EGM96 geoid model, set this to ALT.
Route Altitude 200-400ft (60-120m) How high would I like to fly compared to the take-off point? The height balances how fast you would like to complete the survey (higher makes it faster) and the ground sampling distance you need (lower makes it better).
Elevation Optimization Disabled Is the terrain or altitude expected to vary during the flight? When enabled, the drone will take a few oblique images at the end of the flight. You do not need these to process your data with Propeller.
Safe Takeoff Altitude User Preference What is the height of the lowest potential obstacle in my survey boundary? The drone will take off vertically to that height and then fly at a diagonal to the start point for the rest of the ascension to the start point.
We recommend setting it to the same altitude as the mission.
Speed *Max Speed Allowable How fast should I fly? *Unless you’re trying to reach the required 10 minute flight time, increase speed to minimize the overall flight time. In low light conditions, reduce the speed and the shutter speed to ~1/800.
Course Angle User Preference What direction should I fly to cover the survey area? Fewer turns mean more area covered per battery. For linear/narrow surveys, use the Linear Flight Mission mode instead of Mapping.
Upon Completion Return to Home What should I do after completing the mission? Using this setting is safer and prevents losing your drone. Once completed, the drone will go back to the home point automatically.
Advanced Settings Set to Question to Ask Yourself Reason
Target Surface to Takeoff Point 0 Is the terrain I want to survey at a different altitude than my home point? Unless the terrain that you are surveying is at a much different height than your home point, leave this at 0.
Front and Side Overlap ~80% How much should each of the images overlap? This provides enough overlap for some images to be missing or of poor quality while still building a contiguous model. The lower the detail on the surface below, the higher your overlap should be.
If you have a large area to survey, you can reduce the horizontal overlap (no lower than 60%) to increase the area you can cover per battery
Margin 0 How much margin do you want to leave around the survey area? Provided you have covered the entire area you would like to survey accurately, you don’t need any margin.
Photo Mode Distance Interval Shot What metric is used to capture images? Distance shooting allows the drone to capture images with consistent overlap.

Data Upload 

After creating a site, you can then begin the upload process. 

Upon the drone’s first upload, you will be prompted to register the drone in Propeller.
