Referencing in Photogrammetry – Important Basics
Referencing in photogrammetry – is a set of actions in the field and post-processing that allows to scale, orientate and place a photogrammetry project correctly. A photogrammetry project with referencing is in the correct position in relation to the real world, has a scale, and can be measured. Ref
In our blog and software help we often use terminology that might not be clear for everyone. Thus we decided to create our own glossary of most common terms used in the context of photogrammetry. 3D Mesh3D ReconstructionBreaklinesCameraCamera LensCamera PositionsContour LinesDense Point CloudDEMDron
How to use an RTK Drone as a GNSS Rover?
We explored the pros and cons of using an RTK drone and GNSS rover ground control points for accurate aerial photogrammetry referencing in another article. Not unexpectedly best results were achieved using both sources for referencing simultaneously. As we classified the RTK drone and the GCP device
Ground Control Points vs. Real Time Kinematic
With aerial photogrammetry, there are two most commonly used types of referencing – GPS metadata in the photos and ground control points in the scene. GPS metadata can come in the level of RTK precision, while ground control points (further GCPs) are always made with survey-grade equipment. In this
Flight Planner. Do I Need One?
Drones have become a standard instrument for businesses worldwide, including agriculture, real estate, photography, and manufacturing. Unmanned aerial vehicles significantly improved our capacities in 3D mapping, business automation, and even military operations. Flight planner applications are req
RTK Drones: What You Should Know
RTK drones used for drone mapping provide GPS accuracy and order of magnitude better than consumer-grade GPS units. It makes the RTK drones a viable mapping and 3D scanning solution where precision is critical for real-world applicability. Consumer-grade drones utilize consumer-grade GPS units and c
Photogrammetry with DJI Mavic 3 – Orbital Scanning
With no SDK available – manual Orbital Scanning techniques can be crucial if you want to utilize your Mavic 3 camera for photogrammetry. In the previous article, we discussed using currently available functions for nadir scanning. Now we are going to take a look at semi-automatic orbital scanning ca
Photogrammetry with the Mavic 3 – No Flight Planner Required Part 1
It has been a few months since the launch of the Mavic 3, which took the position of the latest and greatest drone from DJI. DJI has yet to release a compatible mobile SDK (software development kit) to enable drone control by third-party apps. No third-party apps mean – no automatic flight planners
Photogrammetry Fails and Issues Part 2
In the previous article, we have started our glance-travel through the most common photogrammetry fails and issues. There are many causes for inaccurate or failed 3D projects. Fortunately, extensive experience of the Pix-Pro team might be of help on how to deal with specific cases in your project. L
