The invention discloses a spatio-temporal data matching method, device and equipment, relates to the technical field of satellite remote sensing, and is used for solving the problem of low spatio-temporal data matching efficiency in the prior art. The method comprises the following steps: acquiring at least two to-be-matched data, and setting a space-time window; performing data screening and data structure unification on the to-be-matched data to obtain first to-be-matched data; sorting the time parameters in the first to-be-matched data and taking an intersection to obtain second to-be-matched data; continuing to sort based on the latitude parameters and taking an intersection to obtain third to-be-matched data; sorting the data meeting the preset longitude range according to the longitude parameters and taking an intersection to obtain fourth to-be-matched data; performing distance calculation on data in the fourth to-be-matched data in the space-time window; and storing the points smaller than the space w
