Drone 3D Modeling

Drone 3D Modeling is to use the aerial photogrammetry to generate a 3D model. Drone 3D Modeling is using the using a series of photographs taken by a drone as it can generate with a data point cloud 3D map to measure everything in the 3D model such as volumetric calculation, distance measurement and etc. Drone 3D Modeling will be getting more important for clients as the 3D modeling can visualize the building before they start the projects. Drones enable us to capture details, intricacies, and beauty of a structure not easily seen from the ground level. MIRS Innovate Singapore is the drone specialist to provide Drone 3D Modeling services as MIRS Innovate has the professional production team with full of experience to provide the solutions to our clients. Our fully licensed and insured drone filming teams are able to provide 2D and 3D mapping services to the clients.

Drone 3D Modeling has even been used in Hollywood

Drone 3D Modeling will utilize the data from the drone camera to generate the 3D model. This method of generating a 3D modeling of environment is widely being used in the film movie production and this is why all the movie stars acting in the green or blue screen.

Drone 3D Modeling is cheaper than what you expect

Drone 3D Modeling will not as expensive as what you think. Drone 3D Modeling function addresses an increasing need in the construction industry. Drone mapping services and 3D modeling are getting more time and cost effective due to the latest drone camera technology can save more labour cost to generate the data for the 3D modeling.

Workflow Summary of Drone 3D Modelling

Step 1: Buy a Drone

Drones are getting cheaper, smaller and increasingly powerful by the minute. For this workflow, we used the DJI Phantom 4 RTK. It costs SGD 6,800, weighs less than 2 kilograms and it can fly for 20 minutes on one battery. The DJI Phantom 4 can also cover a distance of 10 kilometers and make 4K video and high quality images with good resolution. This is adequate for our purpose of creating 3D environments as a backdrop for architecture design or visualization. 

I will recommend to buy some extra batteries for the 3D modeling projects as it could spend you half day to do it.

Step 2: Capture Drone Images

Using a special app on your tablet for controlling a drone such as DJI GS RTK APP, the second step is to capture images around the area of interest.

A new GS RTK app allows pilots to intelligently control their Phantom 4 RTK with two planning modes – Photogrammetry and Waypoint Flight – alongside a more traditional flight mode. The planning modes let pilots select the drone’s flight path while adjusting overlap rate, altitude, speed, camera parameters and more, offering an automated mapping or inspection workflow.

The GS RTK app has been built with its users in mind and therefore has a range of features built for specific mapping or inspection workflows. The app has implemented direct loading of KML area files for in-office flight planning, a new shutter priority mode to keep exposure consistent across all photos and a strong wind alarm to warn pilots of adverse conditions.

The Phantom 4 RTK is compatible with the DJI Mobile SDK, opening up its functions to automation and customisation through a mobile device.

Support your Phantom 4 RTK missions with the D-RTK 2 Mobile Station – providing real-time differential data to the drone and forming an accurate surveying solution. The Mobile Station’s rugged design and OcuSync 2.0 transmission system ensures you can gain centimetre-level accurate data with your Phantom 4 RTK in any condition.

Do five runs of the same flight path above the desired area, but make sure you assign a different camera angle for each flight. For instance, you can fly the first run with the camera pointed down and the other four runs with the camera tilted at 45 degrees. Each run takes 7 to 15 minutes, so the entire flying will take about 1.5 to 2 hours overall without setting ground control point.

Step 3: Data Processing

Gather all of your images and import into software such as Pix4d, Context Capture and etc to do the data processing. You will need a high specification of PC to run the data processing smoothly. The 3D modelling will be ready after certain hours.
