Abstract
An apparatus, method for lens barrel distance adjustment, device and computer medium are provided. The method includes: obtaining an eye image of a user; determining a pupillary distance of the user based on the eye image; obtaining a first output voltage determined by a hall sensor; in response to that the first output voltage indicates that an absolute value of a difference value between a distance between left and right lens barrels of a head-mounted device and the pupillary distance of the user is greater than a predetermined threshold, sending a control instruction corresponding to the difference value to an adjustment circuit, causing the adjustment circuit to adjust a distance between the left and right lens barrels based on the control instruction. The hall sensor and the adjustment circuit are provided on the head-mounted device.
