1. A system, comprising:

  • an unmanned aerial vehicle comprising a plurality of cameras;

    a head-mounted wearable device comprising;

    a transparent display through which physical objects of a physical, real-world environment are visible and on which is presented virtual information in relation to the physical objects; and

    a pattern that is recognizable by the plurality of cameras; and

    a computing device in communication with the plurality of cameras and the head-mounted wearable device, the computing device configured to;

    provide an augmented reality interface at the transparent display of the head-mounted wearable device;

    provide, at the augmented reality interface, directions for a wearer of the head-mounted wearable device to move between a plurality of locations with respect to the plurality of cameras;

    receive a first indication that a first camera of the plurality of cameras mounted on a first side of the unmanned aerial vehicle recognized the pattern at a first location with respect to the first camera;

    receive a second indication that a second camera of the plurality of cameras mounted adjacent to the first camera recognized the pattern at a second location with respect to the second camera;

    generate a confirmation message when it is determined that the first location and the second location correspond to a same location with respect to the unmanned aerial vehicle;

    access existing calibration data for at least the first camera and the second camera; and

    validate the existing calibration data with respect to the first camera and the second camera based at least in part on the confirmation message.
