The invention discloses a spherical permanent magnet trajectory tracking method and system based on sub-pixel visual positioning. The method comprises the following steps: configuring a first sample set representing sample spherical permanent magnets; configuring at least one convolution model; respectively updating the first sample set into second sample sets through at least two interpolation rules, training a convolution model according to a plurality of second sample sets corresponding to different interpolation rules, and selecting a trained convolution model corresponding to one interpolation rule as an optimal model; acquiring first visual images of a spherical permanent magnet to be detected at at least two moments; obtaining the first visual image as a second visual image according to an interpolation rule corresponding to the optimal model; obtaining image coordinates of the second visual image according to the optimal model; and according to the image coordinates at the at least two moments, obtain
