Vision sensor error
One or more vision cameras is not working correctly.
DJI vision sensor error
DJI vision sensor error: causes, checks and repair.
DJI drones use pairs of vision cameras to hold position and avoid obstacles. When the app shows "Vision sensor error", "Vision system abnormal", "Vision sensor calibration required" or "Obstacle sensing unavailable", the drone can drift indoors and will not brake for obstacles. Sometimes cleaning or recalibrating fixes it; after a crash it often needs a repair.
Error messages this page covers
Forward, backward, downward and side vision systems can all report faults.
Vision system abnormal / vision sensor blocked
Sensors are dirty, covered or see an image that does not match.
Vision sensor calibration required / calibration error
The stereo camera pair needs to be recalibrated, or calibration failed.
Downward vision sensor error
Positioning and landing protection may not work; the drone can drift.
Obstacle sensing unavailable
Obstacle avoidance and APAS are switched off until the fault clears.
Drone drifts while hovering
Vision positioning is not holding the drone in place.
Safe checks to try first
Try these before booking a repair.
Clean the sensors
Wipe every vision sensor lens with a clean microfibre cloth. Smudges, dust and propeller residue are common causes.
Check lighting and surface
Vision positioning needs good light and a textured surface. Water, glass, plain floors and darkness confuse it.
Unfold the arms fully
Folded or half-folded arms can block a sensor and cause errors or calibration failure.
Restart and update
Power-cycle the drone and controller and update the aircraft firmware.
Calibrate with DJI Assistant 2
On supported models, vision calibration runs in DJI Assistant 2 on a computer. Use a flat (not curved) monitor at its default resolution, as DJI support advises.
When it needs a repair
Book a diagnosis if the error stays after cleaning and calibration, or if:
There was a crash or hard landing
Impacts can crack a sensor, shift a camera module out of alignment or damage its cable.
Calibration fails at the calculation step
Often a misaligned or faulty sensor pair rather than a software issue.
A sensor lens is cracked or fogged
Moisture or a cracked cover glass needs cleaning or replacement.
The error came with other warnings
Combined vision, IMU or compass errors can point to frame or board damage.
How NVX repairs vision sensors
We check each vision camera, its cable and mounting, clean or replace damaged sensors and cover glass, recalibrate the vision system and test hover stability and obstacle sensing where safe. We work on DJI Mini, Air, Mavic, Avata, Phantom and enterprise models. NVX is an independent repair service and not a DJI-authorised service centre.
How it works
The same tracked process for every repair, whether you visit or courier the drone.
1. Submit a repair request
Model, what happened and a few photos. It takes about three minutes.
2. Drop off or courier
Bring it to Connaught Place or send it by courier. Contact us first about damaged batteries.
3. Diagnosis and quote
A technician finds the fault and quotes before any work starts.
4. Repair, calibrate, test-fly
Approved work is done, sensors are calibrated, and the drone is test-flown where safe.
5. Collect or receive
Pick it up or get it couriered back, with a summary of the work done.
FAQ
DJI Vision Sensor Error: common questions
How do I fix a DJI vision sensor error?
Clean all sensors, fly in good light over a textured surface, unfold the arms fully, update firmware and calibrate the vision sensors with DJI Assistant 2 where supported. If the error remains, book a diagnosis.
Is it safe to fly with a vision sensor error?
Only with caution in open space. Positioning and obstacle avoidance may not work, so the drone can drift and will not brake for obstacles.
Why does DJI vision calibration fail?
Common causes are a curved or small monitor, folded arms, dirty sensors, or a sensor knocked out of alignment in a crash.
Can a DJI downward vision sensor be repaired?
Yes. The sensor, cover glass or cable can be cleaned or replaced and the system recalibrated. You get a quote after inspection.
How much does vision sensor repair cost?
It depends on the model and which sensor is damaged. NVX diagnoses first and quotes before any work.
Do you repair DJI vision sensors in Delhi NCR?
Yes, at our Connaught Place workshop in New Delhi, with courier for Noida, Gurugram and the rest of India.
