Abstract: Aiming to solving the problem of positional discrepancy of corresponding objects in multi-scale polygonal object matching and that the potential matching pairs can't be directly identified by the method of areal overlapping, it is proposed that a multi-scale polygonal object matching method based on minimum bounding rectangle combinatorial optimization algorithm. The basic idea of our method is that:①identifying the potential matching pairs of 1:1, 1:N and M:N with combinatorial algorithm and simple shape characteristic;②establishing multi-characteristic artificial neural network model to evaluate these potential matching pairs. The proposed method is demonstrated in the experiment of matching between 1:2000 and 1:10000 polygonal objects of residential buildings and industrial facilities in Zhoushan, Zhejiang Province. The experimental results showed that the proposed matching method show superior performance against a method of area overlapping and artificial neural network. Its precision and recall are 96.5% and 89.0% under the positional discrepancy scenario, and it successfully match 1:0, 1:1,1:N and M:N matching pair.
