Principle of 3-axis gimbal stabilizer/ What is a 3-axis gimbal stabilizer？

The 3-axis cell phone gimbal stabilizer is a handheld device that works in tandem with three rotational axes (pitch, roll, and heading) and built-in motors to counteract the shaking of the cell phone while filming, and help the user to take smoother and more stable videos or photos.

Core Composition and Principle:
Three-axis structure:

Pitch axis (Pitch): controls the phone to tilt up and down (e.g. head up/down).

Roll: Prevents the phone from tilting left or right (e.g. sideways).

Heading axis (Yaw): adjusts the phone's left/right horizontal steering (e.g. turn left/right to shoot).

Sensors and Algorithms:

Built-in gyroscope, accelerometer and other sensors detect the movement of the phone in real time.

Through the algorithm to calculate the compensation direction, drive the motor reverse movement to offset the jitter.

Motor Drive:

Brushless motor responds quickly and accurately adjusts the position of the phone to keep the picture stable.

Core Functions and Uses:
Dynamic Anti-Shake: eliminates picture shake when running, walking or shooting on the move.

Multi-mode shooting:

Follow Mode: Lock the subject to automatically track (e.g. people, pets).

Time-lapse: Stabilizes long time moving time-lapse video.

Panorama Mode: Aids the phone in smooth panoramic shots.

Extended control:

Bluetooth connection to the phone, remote control shooting (zoom, switch mode, etc.) through the handle buttons or APP.

Some of them support gesture recognition or AI tracking (e.g. than gesture to start shooting).

Advantage comparison:
VS two-axis stabilizer: three-axis can cope with more complex motion scenes (such as going up and down stairs, rotating the lens), and the anti-shake is more comprehensive.

VS Mobile phone electronic anti-shake: physical stabilization avoids image cropping and retains higher picture quality and wider viewing angle.

Applicable scenes:
Vlog shooting: keep the image stabilized in the scene of walking and talking.

Sports Recording: Capture clear images during cycling, skateboarding and other sports.

Professional creation: microfilm, product display and other scenes that require fine lens movement.

For example: when shooting a person following the camera, the gimbal can smoothly rotate the phone through the heading axis and adjust the shooting angle with the tilt axis, so that even if you follow the camera quickly, you can still output movie-level smooth images.
