DJI Vision Sensor Calibration (Mavic Pro/ Phantom 4/ Mavic 2 / FPV)

Vision sensors are so important for drones for safety features like obstacle avoidance. Actually, they are the eyes of the drone (as the name sounds), even though it has more than two. DJI engineers have put so much effort into optimizing and advancing the vision sensors of DJI drones. So There is no argument that DJI drones have advanced vision sensors.

Even though those vision sensors are capable of figuring out obstacles, they need to be calibrated before use, in order to function properly. If DJI vision sensors are not properly calibrated, vision sensor calibrations errors would be popped on the DJI Go/ DJI Fly app.

Why you should calibrate DJI vision sensors?

Vision sensors are so important to figure out obstacles, and surrounding and avoid crashing into them when the user is unable to manage the situation. In order for vision sensors to function in those situations, need to be calibrated before. Unless users have to be so careful when flying the drone because won’t be able to save itself from a crash.

When you should calibrate DJI vision sensors?

When the DJI drone requires vision sensor calibration, the DJI GO/ DJI Fly app would alert you with forward/backward/downward vision sensor calibration errors. So whenever you see that kind of error on DJI Go/ DJI Fly app, you should calibrate vision sensors. Also if you notice some malfunctions of features like obstacle avoidance, it’s advisable to calibrate vision sensors.

Before calibrating the vision sensors download and install the latest DJI Assistant 2 to your PC.

How to install DJI Assistant 2 to PC.

If you have already installed outdated DJI Assistant 2, first uninstall that application from your PC.

Then open your browser (Google Chrome/ Firefox/ Safari) and visit the DJI Download center.
Then choose Software> DJI Assistant 2 for Phantom/ Mavic from the left sidebar.

If you are a mac OS user, click on pkg and download the package file and download it. If you are a Windows OS user, click on “exe” or “zip” to download the installation file of Assistant 2.

Once it is downloaded, install the DJI Assistant 2 application to your OS.

How to Calibrate DJI Mavic Pro/ Mavic 2/ Mavic Air/ DJI FPV Vision Sensors.

Open the DJI Assistant 2.

Connect the aircraft to the PC using the USB cable.

Click on the box that popped on the screen.

Then enter your DJI account details that is connected to your drone and log in.
Then click on the “Calibration” tab on the left sidebar.

Now you’ll see some tutorials on calibration. Once you are ready, click “calibrate now”.

Backward and side vision sensor calibration won’t be available for some drones.

Forward vision sensors calibration.

Face the drone front to the screen and bring it closer to coincide red corners with green corners. (hold the drone in the position as shown on the left side of the screen). The green markers would go away and a blue box would pop on the screen. Also, you see another blue box which is the position of the forward vision sensor.

Then move the vision sensor box onto the blue marked box on the screen. When moving the vision sensor, think like the drone is connected to a tripod and just tilt instead of moving the drone around.

Keep following the blue mark pop on the screen. Eventually, the forward vision sensor calibration would be finished.

Downward vision sensors calibration.

As before, face the drone belly to the screen and bring it closer to coincide red corners with green corners. (hold the drone in the position as shown on the left side of the screen)

Then keep following the blue mark by tilting the aircraft’s belly. Eventually, the downward vision sensor calibration would be finished.

Backward vision sensors calibration.

Face the aircraft back to the screen and bring it closer to coincide red corners with green corners. (hold the drone in the position as shown on the left side of the screen)

Then keep following the blue mark by tilting the aircraft’s back. Eventually, the backward vision sensor calibration would be finished.

Side vision sensors calibration.

Before calibrating side sensors, fold the drone legs.

Face the right sensor to the screen and bring it closer to coincide red corners with green corners. (hold the drone in the position as shown on the left side of the screen)
Then keep following the blue mark by tilting the aircraft. Eventually, the right-side vision sensor calibration would be finished.

To calibrate the left sensor, turn around the aircraft and face the left-side vision sensor to the screen.
Then bring it closer to coincide red corners with green corners.
Then keep following the blue mark by tilting the aircraft. Eventually, the left-side vision sensor calibration would be finished.

Calculation process.

Then wait for a few minutes until the calculating process is done and settings are applied to the drone.

Once the calibration process is done, restart the aircraft.

How to Calibrate DJI Phantom 4 Vision Sensors.

Open the DJI Assistant 2.

Power on the Phantom 4 and connect to the PC using the USB cable.

Click on the Phantom 4 box that popped on the screen.

Then enter your DJI account details that is connected to your Phantom 4 and log in.

Then click on the “Calibration” tab on the left sidebar.

Now you’ll see instructions to calibrate vision sensors. Once you are ready, click “Start calibration”.

DJI Phantom 4 forward vision sensors calibration.

Face the aircraft’s front to the screen and bring it closer until the red corners of the box coincide with the corners of the blue box.

Then hold it in that position and wait for a few seconds.

Then tilt the aircraft up to down to fill the vertical progress bar.

Then tilt the aircraft left to right to fill the horizontal progress bar.

Then move to the downward vision sensor calibration.

DJI Phantom 4 downward vision sensors calibration.

Face the aircraft’s belly to the screen (the battery compartment should point to the right) and bring it closer until the red corners of the box coincide with the corners of the blue box.
