Forward and downward binocular vision is used for visual positioning, and the downward ToF is used for providing height information for the Z-Axis.

The forward and downward binocular vision sensors are suitable for scenarios with ample sunlight and texture details, while the downward ToF is more suitable for scenarios that feature objects with low reflectivity.

The effective measurement height is within 4 m for objects with reflectivity >30%, and within 2.5 m for reflectivity >7%.

DJI's proprietary computer vision, deep learning technology, and the robust computing power of CineCore 3.0 allow ActiveTrack Pro to support the reliable tracking of almost any subject. It can effectively recognize human faces, heads, shoulders, and even arms and legs. Continuous tracking of people is available even from longer distances. You can now attain tracking shots effortlessly and even adjust composition at any time during tracking.

Yes, but the Z-Axis is not available in underslung mode.

No.

1. Before using the Z-Axis, make sure the axis lock on the base plate is unlocked and the Z-Axis is balanced. For balancing, please refer to the after-sales tutorial video Balancing.
2. To make the best use of the Z-Axis, try to hold the Ronin 4D upright during use.

Auto Calibration calibrates control parameters according to current payload, and eliminates accumulated errors of the sensor to ensure optimal gimbal performance. We suggest Auto Calibration any time after changing the lens, installing the X9 Focus Motor, or adding a counterweight, and re-balancing. During calibration, place the stabilizer on a level surface.

Make sure the gimbal and Z-Axis are fully balanced. Then, conduct Auto Calibration.
To use the LiDAR Range Finder and electric lens, we suggest using the X9 Counterweight (106 g) before balancing and Auto Calibration. If you are using a contactless manual lens, you can directly mount the X9 focus motor without the X9 Counterweight (106 g).
If tilt-axis jitter still occurs after the operations above, contact DJI Support for assistance.

Tap the gimbal balance detection icon and check the balance of the gimbal and Z-Axis.
If the balance detection icon turns yellow/red, calibrate the gimbal/Z-Axis according to the instructions.
After balancing, go to HOME - Stabilizer - Calibration and tap Auto Calibration to calibrate gimbal stiffness.

Please refer to the tutorial video - Focus Point Control.

The LiDAR Range Finder is ready to use without the need for calibration.

The LiDAR Range Finder currently supports only DJI Ronin 4D.

Ronin 4D uses LiDAR focusing. The LiDAR Range Finder can cast 43,200 ranging points.

The 3D focusing system of DJI RS 2 uses single-point focusing that only focuses on the center of the target, while the LiDAR Range Finder can cast 43,200 ranging points, enabling faster and more accurate focusing and providing visual focusing with the LiDAR Waveform.

Please refer to the tutorial video - Focus Point Control.

Currently no.

Calibration is required when working with manual lenses or lenses that do not support electronic focusing. Calibration steps: After installing the focus motor, Press the HOME button once to enter the menu, go to Lens - Calibration, tap Focus Motor Initialize, and wait for it to finish.

The actual operating and environmental temperature, number of existing files, and total bytes written (TBW) when using a third-party USB-C SSD can greatly affect the write performance. For accidents like frame loss or recording stops, please check the following:
1. Make sure the SSD is running within an appropriate temperature range. It is recommended to use it in a cool and well-ventilated environment and to use a metal frame with adequate heat dissipation performance to fix the SSD. Overheating can reduce the write performance of the SSD. For recommended operating temperature of the SSD, please consult the manufacturer.
2. Before using the USB-C SSD to record, make sure you have formatted it on DJI Ronin 4D. If the SSD is already storing many files written by other devices, the write performance may decrease significantly as affected by wear leveling and garbage collection algorithms of the SSD.
3. When TBW of the SSD is large, bad blocks can increase and significantly reduce the write performance. It is therefore recommended to use the SSD with smaller TBW when recording.
