The invention relates to a three-dimensional mold matching method for a wood template, which comprises the following steps of: 1, establishing a three-dimensional model of a structure, and matching the mold of the wood template in a three-dimensional environment based on the model; 2, during mold matching, conducting mold matching according to the sequence from a floor formwork, a beam plate template a wall plate formwork to a stair formwork and according to the principle of matching between the formworks; 3, performing collision check on the three-dimensional mold matching model, discoveringproblems and performing modification in time in the three-dimensional environment, so that the mold matching efficiency and precision are improved; 4, counting and analyzing the template model and specification of the summarized mold matching data and the utilization rate of a single plate; fifthly, in order to improve the utilization rate of a single plate, reasonably combining templates of different specifications; and 6, generating a final template blanking scheme. The use rate of the wood template is increased, waste is reduced, and the total use amount of the template is reduced.
