The invention relates to a spatial model construction method and system based on fusion point cloud data, and the method comprises the steps: responding to a plurality of obtained point cloud data groups, and transferring each point cloud data group into a same coordinate system; screening two groups of point cloud data in one group of point cloud data group to obtain two groups of feature points; generating a feature curve segment based on a group of feature points; and comparing the lengths of the two characteristic curve sections belonging to the same group, when the lengths of the two characteristic curve sections belonging to the same group are equal or within an error range, obtaining a standard base point, generating a guide curve based on the obtained standard base point, and generating a three-dimensional model of the cable according to the guide curve. According to the fusion point cloud data-based spatial model construction method and system disclosed by the invention, modeling is carried out on th
