Primitive position relationship matching method and device and computer equipment

The invention provides a primitive position relationship matching method and device and computer equipment. The primitive position relationship matching method comprises the steps of firstly obtaining feature information of each standard legend in a standard library, and then searching a target core primitive of which the category is the same as that of a basic core primitive of each standard legend in a drawing; searching for whether a target legend with the target core primitive as the center exists in the drawing or not, wherein the category and number of reference primitives contained in the target legend are the same as those of basic primitives contained in the corresponding standard legend. If yes, judging whether the position topological relation between the reference primitives contained in the target legend is the same as the position topological relation between the basic primitives contained in the standard legend or not, and if yes, determining that the target legend is matched with the standard
