Does DJI have to be calibrated every flight?

If the App prompts for visual calibration, it is recommended that you conduct visual calibration in time. In order to ensure the best flight positioning accuracy, the aircraft will automatically detect the deviation of the binocular vision system. At this point, binocular vision calibration can be solved by adjusting the parameters of App or PC. We suggest that you carry out visual calibration regularly to ensure that the visual system of the aircraft is in normal condition.
