The LiDAR (Light Detection and Ranging) mapping drones have revolutionized several industries. Such as agriculture, construction, and urban planning by reflecting and showing highly detailed 3D topography and spatial objects. Moving forward with building your own homemade LiDAR mapping drone may turn into an exciting and joyful project. It is yours to get the design you want within your budget. In this article, we will describe the process of building a LiDAR mapping drone from scratch. We’ll also explain, from choosing the appropriate parts to assembling and testing the drone.

Understanding LiDAR Technology

LiDAR is a spaceborne sensing method that emits laser beams that go a long distance to objects on Earth, including seas and oceans. LiDAR system impresses with its precision timed out of shooting a laser beam. And analyze the echo of the light once it has hit a target. Detecting reflective signals from the target area, a LiDAR system develops topographic maps of buildings, trees, vegetation, etc. All details can be recognized precisely.

Selecting the Right Components

In addition, you should assemble all the parts you need for your LiDAR mapping drone. You will also have to order them. Here’s a list of essential components: 

Drone Frame: Select a strong, rigid frame that can hold the LiDAR sensor and support other devices.

Flight Controller: The UAV controller plays a leading role in stabilizing and regulating flight. It can be called the heart of the UAV.

LiDAR Sensor: The primary concern for choosing a LiDAR sensor is that it should be able to measure a three-dimensional environment accurately with better resolution and a much wider scan range.

GPS Module: GPS is one of the vital tools for geotagging CLASS data and, thus, confirming the actual location of the depicted items within the surveyed area.

Battery and Power System: For your smoothed-out drone, use the stable battery and electrical system that the drone could…

Communication System: Develop a communicator system, which may be a radio and TV telemetry or telemetry as required for real-time monitoring and control of the drones.

Assembling the Drone

To do this, collecting the required parts for the drone has to come next. 

Attach the Frame:

The flight controller, LiDAR sensor, GPS module, and so on on the drone frame shall be installed according to the manufacturer’s specifications.

Connect the Electronics:

Collect all the electronic parts mentioned, including the flight controller, LIDAR sensor, GPS module, and communication. A graphic diagram from the manufacturer guides is provided along with the product.

Install the Propellers:

Place propellors onto motors and secure them using pertinent maintenance tools while at the same time ensuring their equal balance.

Calibrate the System:

Ensure your process obtaining the proper pilot licenses and personal certificates, except those that will allow a space traveler to a breakaway point.

Testing and Calibration:

Before deploying your LiDAR mapping drone for actual mapping missions, it’s essential to conduct thorough testing and calibration: 

Flight Testing:

Test the prototype during flight missions and check if it behaves according to the plan, is as maneuverable as expected, and covers all mission characteristics. Get the right systems in place, check the laser scanning’s precision in advance, and do excellent data collection.


Establish the calibration of LiDAR sensors and other sensors so they can distinguish high degrees of temperature and time. Transitionally (transitioning phrase): This process enables the data to be worked with, valid, and trustworthy.

LiDAR Targets

For this LiDAR survey, control points or objects distributed throughout the survey area are called LiDAR surveying targets. Targets are used to make LiDAR mapping more reliable and accurate. This provides one baseline for an electromagnetic emitting beam system, followed by the LIDAR sensor. Referencing and ground control are established through these positional comparison measurements. Placing the LiDAR spots in the study area in a planned manner will be beneficial, as it will improve the quality of the mapping information and the errors of the maps.


Mapping drones is an intricate and rewarding hobby, especially when you practice some hands-on skills with your own LiDAR mapping drone. This interface provides the ability to use different sentiments in any geospatial mapping and remote sensing activities. So, preparing the drone according to a schedule and performing detailed testing and adjustment is the way to perfection. Read more blogs here:
