Drones have already taken many industries by storm, because it seems there may be rather more to drones than flying wedding ceremony cameras. Most industrial drones are able to path planning and semi-autonomous flight, however to be really autonomous they might want to incorporate precision touchdown.
What’s drone precision touchdown you ask? Virtually all drones will come geared up with a GPS which permits the drone to fly primary missions after which land. The issue is a drone with solely GPS guided touchdown is just correct to round 10 toes. For some drone functions like land surveying, most likely received’t hinder the efficiency of the mission.
Nonetheless, in lots of potential drone functions, 10 toes accuracy merely doesn’t get the job completed. Enter precision touchdown, which permits an uav to land on a goal with round 10 inch accuracy. Try the video under for an instance of 1 technique of imaginative and prescient primarily based precision touchdown (mentioned later).

Drone Functions Requiring Precision Touchdown
- Package deal supply
- Precision agriculture
- Drone in a field
- Warehouse stock scanners
- Charging stations
- Surveillance
Think about attempting to ship a package deal to somebody’s yard with solely a ten ft accuracy. Feels like damaged home windows and lawsuits to me. Mainly, to be a very autonomous drone utility with no human involvement within the mission, precision touchdown is a requirement.
Of observe, with the data of python drone programming, any one in every of these drone functions could possibly be scripted.
Precision Touchdown Strategies
Because of the requirement of precision touchdown in unlocking so many drone functions of the long run, numerous options are arising. Virtually all strategies include some drone-side digicam or sensor, which is monitoring some object on the bottom. The place of the drone relative to the touchdown goal is then calculated and communicated to the drone’s firmware. From right here, the drone will place itself to attenuate the space from the goal.
Overview of Precision Touchdown Drone Strategies
I. Laptop Imaginative and prescient Precision Touchdown
With this technique, all that’s bodily required is a digicam and companion pc on the drone, and an aruco marker on the bottom. The scale of the aruco marker is pre-determined, in order that the space between the drone and the marker will be calculated primarily based on how massive or small the marker seems within the body.
Utilizing the dronekit and openCV libraries in python, this complete course of will be simply achieved. This technique is engaging as a result of the bottom facet goal doesn’t require energy, as it’s merely a paper picture with an array of black and white containers.
PROS:
- Floor facet goal doesn’t require energy
- Scalable
- Low-cost
CONS:
- Requires guide openCV python scripting
- Doesn’t work in fog or darkness
II. IR Lock Precision Touchdown
A substitute for a pc imaginative and prescient primarily based technique is the patron prepared product IR Lock. Right here, a modified PixyCam with an IR-lens is hooked up to the drone, and the groud-side goal is an IR-emitting sensor referred to as a markone beacon. With this technique, there is no such thing as a python or openCV scripting required. Merely activate the proper parameters within the firmware, and the drone is precision touchdown succesful.
PROS:
- Shopper prepared/don’t want particular data
- Works in fog or darkness
CONS:
- Comparatively costlier in comparison with imaginative and prescient primarily based precision touchdown
- Not as scalable (Each touchdown goal would require a powered markone beacon)
Subsequent Steps
In case you are all for studying develop your individual imaginative and prescient primarily based precision touchdown techniques on your personal functions, I extremely advocate trying out our complete Precision Landing and Drone Delivery course right here on the Drone Dojo.
After completion, you’ll not solely know design your individual sturdy precision touchdown techniques, but additionally first take a look at your design on a simulated digicam drone in gazebo. Then within the thrilling capstone undertaking, we present how you should use your precision touchdown data to design your individual drone supply mission. Taco Copters for everybody!
