Knowing how to calibrate the Mavic 2 Pro and Zoom vision sensors is very important.

If your are receiving the Mavic 2 vision system error, or if your quadcopter is flying erratically, perhaps not hovering correctly, then you need to calibrate the Mavic 2 Vision Positioning System.

Also, if the Mavic 2 vision system is not working correctly, then it may not detect and avoid obstacles.

Below are the instructions to calibrate the Mavic 2 Pro and Zoom vision system including videos.  You will also find tips to fix the Mavic 2 vision sensor and system errors.

If you are flying your Mavic 2 and the Vision Sensor Calibration error or Vision System Error occurs, you need to fly the quadcopter in straight away and re-calibrate the Mavic 2 VPS using the below instructions.

If the Mavic 2 calibration doesn’t fix the flying difficulties, then check to see if there is a Mavic 2 update available and use the excellent tips below to fix the Mavic 2 vision system error.

The full Mavic 2 calibration is done with the DJI Assistant 2 software. However, if you have no computer with you, then you can perform a quick vision sensor calibration using the DJI Go 4 app.

If you have the original Mavic Pro, then you visit our Mavic Pro vision calibration article as there are differences in the Mavic Pro and Mavic 2 vision system calibration.

Calibrate Mavic 2 Vision Sensor Using DJI Go 4

It is possible to do a quick calibration of the Mavic 2 vision sensors using the DJI Go 4 app. This could be a quick fix if you receive the DJI Mavic Vision Sensor Calibration error or Vision System Error.

Other reasons to calibrate the Mavic 2 VPS is if you feel the Mavic 2 isn’t hovering as stable as it normally does or if you feel the Mavic 2 is slow detecting obstacles or just not flying as it should.

If you don’t have a laptop with the DJI Assistant 2 app to do a full Mavic vision sensor calibration, then you can do a quick Mavic vision sensor calibration using the DJI Go 4 app.

To do the quick Mavic vision calibration, tap on the Aircraft Status in the DJI Go 4 app. Then click on Vision Sensors and start the quick calibration.

What To Do If Mavic 2 Vision Sensor Calibration Fails

  1. Insure that you have the latest Mavic 2 firmware before calibrating the vision sensors.
  2. Only calibrate the Vision Sensors when the light is good and never calibrate near or over reflective surfaces.
  3. Remove the propellers before starting the calibration.
  4. It is best to have batteries full or as close to full on your laptop and Mavic 2 just in case the vision sensor calibration takes longer.
  5. Give yourself plenty of space and have no interruptions while you calibrate the Mavic 2 vision sensors.
  6. Calibration of the Mavic 2 vision sensors require more or less only wrist movement to pivot, tilt and rotate the drone to follow the blue squares on the screen.
  7. Insure you fingers aren’t covering or close to the vision sensors while calibrating the Mavic 2.
  8. Leave the Mavic 2 on during the full process until you see the “Calibration Complete” message.
  9. Don’t forget to restart the Mavic 2 after calibration.
  10. If you are using a laptop and the DJI Assistant 2 is not properly recognizing the Mavic 2 sensors, then try it on a normal desktop computer with external display.

Fix Mavic 2 Vision System Error

The Mavic 2 vision system error does not have to be coming from the vision sensors. It could be caused by the infrared sensors, which are part of the whole Mavic 2 Vision Positioning System. So the process of calibrating the vision sensors would not correct the system error if the problem is with the infrared sensors.

If you’re quadcopter is only new and you are receiving the Mavic 2 vision system error, it is important to troubleshoot the problem as quickly as possible.

With all new DJI products, there is always the option to return the quadcopter but this return period is not very long. However, don’t send it straight back without checking the Mavic 2 and following the below steps as it could be something very simple causing the Mavic 2 vision system error.

Here are some instructions on what to try when you receive the DJI Mavic Vision system errors.

  1. If the Mavic is only new, check that there is no tape or packaging covering the vision sensors on the forward, rear, downward and both sides.
  2. Switch off the Mavic 2, take the battery out and leave it off for about 3 minutes.
  3. If the light is insufficient, then the Mavic 2 vision sensors won’t work properly. See below.
  4. The Mavic 2 vision system won’t work correctly or not at all over polished or reflective surfaces giving cause to the vision sensor See below.
  5. Ensure the vision sensors are clean. Use a soft cloth to remove any dust or debris from the sensors.
  6. Check other parts of your Mavic 2. If the quadcopter isn’t flying correctly because of bent or broken propellers or other parts,  then incorrect information will be sent back to the flight controller, which could lead to the to the system error.
  7. Check to see if there is new Mavic 2 firmware available.
  8. Calibrate the Mavic 2 vision sensors using DJI Assistant 2 software  as described above.
  9. Try the DJI Go 4 Mavic quick calibration described above
  10. Check that you are getting a strong GPS signal in P-Mode.
  11. Calibrate the Mavic 2. If the IMU / compass is not calibrated, the flight control system will not receiving correct information and this may effect the vision system error.

As well as vision sensor issues, you may be having issues where the Mavic disconnects from the Remote Control or DJI Go 4 app.  If you are experiencing these Mavic 2 disconnect issues, then read our article on fixing Mavic Pro and Mavic 2 disconnects.

Performance Of The Mavic 2 Vision System

The Mavic Vision System is affected by its surroundings with the infrared sensor under the Mavic been affected greatly by the surfaces it is being flown over.

Here are some notes on instances and surroundings which can adversely affect your Mavic Vision system;

  • Flying over monochrome surfaces such as pure black, white, pure red, pure green.
  • Flying over reflective surfaces.
  • Flying over transparent surfaces.
  • Flying over moving objects or surfaces.
  • Flying over surfaces that strongly reflect infrared waves away such as mirrors.
  • Flying at high speeds of over 31 mph forward and 27 mph backward to allow the Mavic 2 sufficient time to brake.
  • Flying over small and fine objects such as power lines or tree branches.
  • Flying when the lighting changes frequently and drastically.
  • Flying over extremely dark surfaces. ( lux 40,000).
  • Flying over surfaces without a clear pattern or texture.
  • Flying over surfaces with identical repeating patterns.

Mavic 2 Obstacle Sensing Vision System Information

How To Calibrate DJI Mavic 2 Vision Sensor system

The new Mavic 2 Pro and Zoom can sense objects in 6 directions.  Known as Omnidirectional Obstacle Sensing, this includes left, right, up, down, forward and backward obstacle sensing.

Obstacle sensing for left and right directions is only available in ActiveTrack or Tripod Mode.

Now, while all 6 sides of the Mavic 2 are covered for obstacle sensing, Omnidirectional Obstacle Sensing does not fully cover the full 360 degree circumference arc of the quadcopter.

Please see the DJI Mavic 2 user manual for diagrams showing the obstacle sensing coverage around the quadcopter.

How the Mavic 2 Obstacle Sensing Works

The Mavic 2 Pro and Mavic 2 Zoom are equipped with Forward, Backward, Downward and Lateral Vision Systems including Upward and Downward Infrared Sensing Systems. These all provide omnidirectional obstacle detection, providing lighting conditions are adequate.

The main components of the Forward, Backward and Downward Vision Systems are 6 camera sensors located on the nose, rear end and underside of the Mavic 2 quadcopter.

The lateral Vision System are 2 cameras with one camera on each side of the Mavic 2 quadcopter.

The main components of the Upward and Downward Infrared Sensing Systems are 2 x 3D infrared modules located on the top and underside of the Mavic 2 quadcopter.

The Downward Vision System and Infrared Sensing System helps the Mavic 2 maintain its current position and hover in place very precisely. The Vision and Infrared Sensing system allow the Mavic 2 to fly indoors or in other areas where a GPS signal is unavailable.

Mavic 2 Bottom Auxiliary Light

The Auxiliary light located on the underside of the Mavic 2 improves visibility for the Downward Vision System in bad light conditions.

Obstacle Sensing is fascinating technology and you can read further in this article entitled “Top Collision Avoidance Drones And Obstacle Detection Explained“.
