Head-mounted display equipment calibration method and device and head-mounted display equipment calibration system

The invention discloses a head-mounted display equipment calibration method, a head-mounted display equipment calibration device and a head-mounted display equipment calibration system, and belongs to the technical field of augmented reality. The head-mounted display device calibration method comprises the following steps: controlling an image sensor to collect contents displayed by a head-mounted display device to obtain a first image; acquiring a displacement vector between a to-be-tracked feature point in the first image and a central point of the first image, and when the modulus length of the displacement vector exceeds a first target threshold value, controlling a simulated eyeball to rotate so as to adjust the position of the image sensor, and then re-capturing display content so as to refresh the first image; and when the displacement vector modulus length does not exceed a first target threshold value, controlling the simulated eyeball to stop rotating. The head display device calibration method can
