INTRODUCTION
A gimbal, whether handheld or mounted on a drone, is considered to give the camera operator the freedom of photographing or filming without camera vibration or shake.
Generally motorized by three brushless motors (3-axis), the gimbal can keep the camera level on all axes (pan, roll, tilt) as the operator moves the camera. An inertial measurement unit (IMU) retorts to movement and uses its three separate motors to stabilize the camera.
With the control of algorithms, the stabilizer can notice the difference between deliberate movement such as pans and tracking shots from unwanted shake. This allows the camera to look as if it is floating through the air.
Design, Parts and Top Gimbals for Aerial Filming
Having a top-quality drone gimbal is fundamental to capturing great aerial film, 3D mapping, photography, photogrammetry and other sensor driven imagery.
For drones to be widely used across different sectors, UAV gimbal stabilization technology must keep in line with drone innovation. This is very much the case so far.
Here is a snappy overview of the design and workings of a drone gimbal, including the gimbal components. With this knowledge, you will be able to choose the best drone gimbal for your aerial cinematography.
Knowing the aerial gimbal components will help you if you need to troubleshoot any gimbal issues.
Now, when it comes to drone gimbal innovation, we are finding that the 3rd party manufacturers of cameras and sensors (lidar, thermal, ultrasound etc.) are playing catch up with the drone and gimbal innovation to date.
Drone manufacturers such as DJI, Yuneec and Walkera are not waiting around and have filled this gap by producing their integrated gimbal/cameras.
DJI, Yuneec and Walkera have also partnered with Flir to allow thermal vision sensors to be mounted on their drones.
The latest top drones have almost perfect flight and gimbal stability even in very blustery conditions. This flight and gimbal stabilization is the result of significant improvements in all drone components, including the software controlling these components.
Also, most quality drones today all have 4k cameras, including a multitude of camera settings to capture superb aerial shots in all lighting conditions.
Part of a Drone Gimbal
Two or 3-Axis Drone Gimbal
3-axis gimbals provide better video stability than 2-axis gimbals. This is because 3-axis gimbals stabilize your video on all three axes (yaw, pitch and roll) while a 2-axis gimbal will stabilize only on the pitch and roll axis.
Jittery horizontal, jello or rolling shutter movement, is more evident in videos taken using a 2-axis gimbal due to the lack of stabilization in the yaw axis.
3-axis gimbals can significantly reduce and sometimes eliminate jello due to the third motor, which helps absorb unwanted movement in the yaw axis. However, 3-axis gimbals are more substantial and more expensive than their 2-axis counterparts. They draw more battery power due to having more motors.
CONCLUSION
When it comes to filming, the less vibration and camera shake, the better, you then can capture the best video and still shots for the flight. Afterwards, back in the home or office, there is more work to do, whether it is editing the film or photos and packaging them into a video or catalogue.
It is also correct when it comes to creating 3D models, or 3D maps of structures, the less vibration of the drone and camera is vital. Using a drone to fly autonomously, taking hundreds or even thousands of photos of a land area or building structure needs serious software and computing power to stitch the images together.
